Action Concurrency refers to the revenues and expenses balances of a group of agents in any period and describes their similarity in actions at the same time. Stützel defines Action Concurrency as follows: "Action Concurrency occurs, when - by accidence - the same that applies to the overall economy, applies to individual agents, too" Wolfgang Stützel: Volkswirtschaftliche Saldenmechanik. Tübingen 2011. p. 29 For example, if revenues would be fully spent (without delay) in favor of other agents and all other agents act the same way (strict revenue-expense concurrency), then the demand for credit of each of the agents would be zero.

After turning south to leave US 70, Highway 27 follows US 70 west, ending the concurrency that began in Norman. The highway continues southeast to form a concurrency with Highway 84 which continues into Clark County.

Research and literature on concurrency testing and concurrent testing typically focuses on testing software and systems that use concurrent computing. The purpose is, as with most software testing, to understand the behaviour and performance of a software system that uses concurrent computing, particularly assessing the stability of a system or application during normal activity. Research and study of program concurrency started in the 1950s, with research and study of testing program concurrency appearing in the 1960s. Examples of problems that concurrency testing might expose are incorrect shared memory access and unexpected order sequence of message or thread execution.

The three highways begin a curve to the east-southeast, and SR 22 departs the concurrency to the south-southeast on Crawfordville Road. US 78/SR 10 cross over Long Creek, before curving to the south-southeast and then to the east-southeast.

The two highways bring up a short concurrency before US 64 turns northwest off of I-25 in Raton, then continuing to travel east, this time bringing up a concurrency with US 87 through the towns of Capulin, Des Moines, Grenville, and Mount Dora. The two highways split in Clayton, and US 64 forms another new concurrency with US 56 and US 412\. The three highways barely touch the Texas Panhandle before continuing into Oklahoma.

In Loogootee, the highway begins a concurrency with US 231. The concurrency heads north through the downtown area of Loogootee as a two-lane highway, passing commercial and residential properties. The concurrency ends when US 50 and US 150 turn east and with US 231 heading north. The highway heads east from Loogootee towards Shoals; in Shoals US 150 heads southeast towards Paoli and Louisville, Kentucky, and US 50 heads northeast towards Bedford.

Consequently, a vast body of related research has been accumulated since database systems emerged in the early 1970s. A well established concurrency control theory for database systems is outlined in the references mentioned above: serializability theory, which allows to effectively design and analyze concurrency control methods and mechanisms. An alternative theory for concurrency control of atomic transactions over abstract data types is presented in (Lynch et al. 1993), and not utilized below.

It meets I-22 and US 78 at a diamond interchange, just within the corporate limits of Tremont. Past the interchange, MS 23 changes back to a two-lane road and intersects MS 178, the beginning of a short concurrency through the town. Once the concurrency begins, MS 23 and MS 178 travel westward through the center of Tremont. MS 23 departs from MS 178 to the north less than later, ending the concurrency.

At this intersection, SR 42 joins the concurrency. The three highways curve to the northwest into Musella, where SR 42 departs the concurrency. US 341/SR 7 continues on a nearly northwestern routing and enters Monroe County. They cut through the northeastern corner of Culloden.

In Locust Grove, it meets Alternate U.S. Highway 412. It then heads towards Salina, where it begins a concurrency with SH-20. The two routes split up after running through Spavinaw. SH-82 then has a brief concurrency with SH-28 west of Langley.

The highways curve to the north-northeast and enter Winfield. They intersect the southern terminus of CR 147\. They then have a very brief unsigned concurrency with CR 146\. They curve to the northeast and have a one-block unsigned concurrency with CR 49\.

It turns east again and junctions with SR 13. SR 13 continues north independently and continues south with US 43 at this junction. It does not maintain a concurrency past this point. The route passes through Berry and maintains a concurrency with CR 63.

SR 58 heads east from the western end of the concurrency with SR 45\. SR 58 then has a concurrency with State Road 54 (SR 54). At the intersection with State Road 37 SR 54 ends and SR 58 follows SR 37 south toward Bedford.

North of the downtown area, it has an interchange with Interstate 95 at its exit 130. Starting in Fairfield, SR 104 has a concurrency with SR 139. There is also an intersection with SR 23 which has a concurrency with the SR 104/SR 139\.

About later, the route is joined by PA Route 198, and the concurrency enters the borough of Conneautville. In the borough, Route 198 leaves the concurrency nearly later, and Route 18 continues northward, passing through the borough of Springboro just over north of Conneautville.

At North Main Street, they meet SC 184, which joins the concurrency. The three highways travel through Erskine College and pass Erskine Theological Seminary. Immediately afterward, SC 20/SC 185 splits off onto Anderson Drive. Just after leaving town, the concurrency crosses over Chickasaw Creek.

The route begins at its southern terminus and heads north, turns right, and goes over the Clyde River. It then turns left in Bonshaw for a concurrency with Route 1. Turning right to leave the concurrency, it continues north until it reaches its northern terminus.

Almost immediately is an interchange with I-16/US 17 (Jim Gillis Historic Savannah Parkway). At this point, US 17 joins the concurrency. A short distance later, the concurrency crosses over some railroad tracks of CSX and have an incomplete interchange with Tremont Road.

It passes Wagener–Salley High School. It curves to the north-northeast and begins a concurrency with SC 302 (Aiken Road). The concurrency intersects SC 39 (Railroad Street). Just over later, SC 113 and SC 302 split, with SC 113 heading to the north-northwest.

At Oak Street, SR 135 Byp. joins the concurrency. At North College Street, SR 135 Byp.

It enters Hollifield, where it intersects KY 58\. The two highways have a one-block concurrency.

In 1972, the segment of the highway from the north end of the SR 168 concurrency to Pearson was shifted eastward to travel concurrently with US 221/SR 31 into the city. In 1976, all of the highway from Pearson to SR 158 was hard surfaced. By March 1980, the portion between the SR 135 intersection and the south end of the SR 168 concurrency was shifted to the northwest to form a concurrency with SR 135 to an intersection with SR 168, and then on a longer concurrency with that highway to resume its previous departure. Later that year, the northern terminus was truncated to the SR 158 intersection.

After departing the concurrency heading west once again the road enters the village of Shingō, then crosses into Akita Prefecture. Curving to the north, the road reaches the southern shore of Lake Towada and reenters Aomori Prefecture where it shares a concurrency with National Route 103 as the roads travel west along the shore of the lake. The concurrency enters Akita Prefecture once again before National Route 103 leaves the concurrency, heading southwest while National Route 454 continues north along the western shore. Upon reaching the northern shore of the lake, the route enters Aomori Prefecture once more and has a junction with National Route 102 immediately after.

Then after passing a riverside RV Park, has several more local intersections before the overlap comes to an end. At the end of this concurrency, US 90 turns west along with the Old Spanish Trail toward Marianna, while SR 71 turns northeast at a wye intersection onto Greenwood Highway. The west leg of the wye does not come without some strings though, specifically the concurrency with CR 164 that runs as far west as the west end of the US 90/SR 73 concurrency. This concurrency is short-lived as it branches to the northeast towards Dellwood, Hornsdale, and Chattahoochee State Park in Alabama, while SR 71 curves north.

SR 224 begins at an intersection with SR 26 (Spaulding Road) just east of Montezuma. Just before entering Perry, it meets SR 127 (Marshallville Road). SR 127 begins a concurrency into town. In Perry, the two routes intersect US 41/SR 7, which join the concurrency.

Here, US 221 joins the concurrency. The four highways travel to the north-northwest and curve to the northwest just before reaching East Park Avenue. Here, US 221/SR 31 departs the concurrency. US 41/SR 7 curves to the west and intersects SR 125 (Bemiss Road).

Truck U.S. Route 98-301 was a truck bypass of the concurrency of U.S. Routes 98 & 301 in Dade City, Florida. The road is also unsigned State Road 533. In February 2007, this section was converted into the main branch of the US 98-301 concurrency.

The Ohio Department of Transportation (ODOT) created a temporary eastern terminus for the route at the north end of the SR 7/822 concurrency, where the bridge approach ramps began. The eastern terminus was changed to the south end of the SR 7/822 concurrency in 2013.

Just after entering Millen, they begin to curve to the north-northeast and intersect SR 17 Byp. (South Gray Street), which joins the concurrency. At an intersection with SR 17 (Winthrope Avenue), SR 17 Byp. ends, and SR 23/SR 67 depart the concurrency to the east.

A section of FM 1266 shared a concurrency with SH 96, providing access to FM 646 to the south and FM 518 to the north. This concurrency was removed on May 29, 2003 when sections of FM 1266 within League City were returned to the city's jurisdiction.

Henry Will Jones Bridge. After that, US 221/SR 31/SR 122 depart the concurrency to the north-northeast. Less than later, they meet the western terminus of SR 37 Conn. Then, US 129/SR 11 leave the concurrency, while SR 37 continues to the east.

From the western terminus SR 236 heads east. SR 236 passes through a concurrency with State Road 59 (SR 59) that begins in Guion and heads east towards Milligan. SR 236 heads towards U.S. Route 231 (US 231). SR 236 and US 231 have a rshort concurrency.

When they split, KY 270 resumes its east-southeast direction. It intersects the western terminus of KY 1177 and crosses over Smith Ditch. The highway has a very brief concurrency with KY 141\. During their concurrency, they travel to the north- northeast and cross over Bishop Ditch.

Less than later, they enter Lowndes County. The two highways enter Lake Park, where they have a concurrency with SR 376\. During the concurrency, the three highways travel north of Clayton Lake and the Francis Lake Golf Course. After the concurrency ends, US 41/SR 7 travels northeast of Horselot Lake and to the east of the Twin Lakes. After traveling through Dasher, they have an intersection with the southern terminus of US 41 Bus./SR 7 Bus.

Hierarchical state machines are finite state machines whose states themselves can be other machines. Since a communicating finite state machine is characterized by concurrency, the most notable trait in a communicating hierarchical state machine is the coexistence of hierarchy and concurrency. This has been considered highly suitable as it signifies stronger interaction inside the machine. However, it was proved that the coexistence of hierarchy and concurrency intrinsically costs language inclusion, language equivalence, and all of universality.

The concurrency enters Junction and the concurrency ends with SR 637 heading east and SR 111 heading northeast. The highway leaves Junction heading northeast with the Auglaize River close to the south side of the roadway, resulting in that side of the highway becoming primarily wooded, while the northside of the highway remains bounded by farmland.

SR 58 heads southeast from Carlisle towards Freelandville. In Freelandville SR 58 has an intersection with the northern terminus of State Road 159.

Algorithms such as producer-consumer that are implemented so as to require two or more threads are one example of requiring concurrency to work properly. For instance, consider a bounded container with a capacity for only three items and a program which has one thread doing “PUT PUT PUT PUT,” and another thread doing “GET GET GET GET,” each doing their actions only four at a time. Such a program requires interleaving (concurrency). A program that requires concurrency is more difficult to debug.

Connecting with the city of Hertford, it switches concurrences with U.S. Route 17 Business (US 17 Bus.) in Winfall. After a concurrency, it travels solo again as it goes through downtown Winfall then northeasterly through Belvidere. At Gliden, it rejoins NC 32 for a short concurrency, entering Gates County and through Mintonsville, before separating again at Mitchells Fork. Traveling through the communities of Willow and Vivian, it goes through downtown Gatesville, where it shares a short concurrency with US 158 Bus.

Concurrency control techniques are of three major types: # Pessimistic: In Pessimistic concurrency control, a transaction blocks the data access operations of other transactions upon conflicts, and conflicts are non- materialized until blocking is removed. This is done to ensure that operations that may violate serializability (and in practice also recoverability) do not occur. # Optimistic: In Optimistic concurrency control, the data access operations of other transactions are not blocked upon conflicts, and conflicts are immediately materialized. When the transaction reaches the ready state, i.e.

The highway begins at its intersection with Highway 70 in Grantsburg.The intersection is also the northern terminus of Highway 87. The highway runs south from the intersection in a concurrency with Highway 87, passing through the community of Branstad before leaving the concurrency and running east from it. Near Trade Lake (community), Wisconsin, the highway intersects with four county highways; Y, O, M, and Z. It continues east from there until it reaches Frederic, where a concurrency starts with Highway 35.

Two major generalizing variants of CO exist, extended CO (ECO; Raz 1993a) and multi-version CO (MVCO; Raz 1993b). They as well provide global serializability without local concurrency control information distribution, can be combined with any relevant concurrency control, and allow optimistic (non-blocking) implementations. Both use additional information for relaxing CO constraints and achieving better concurrency and performance. Vote ordering (VO or Generalized CO (GCO); Raz 2009) is a container schedule set (property) and technique for CO and all its variants.

SR 141 then enters New Middleton and has an interchange with I-40 at Exit 254, where it moves to the south side of the interstate and begins a concurrency with SR 53.

All three route heads southeast towards Delphi, west of downtown Delphi State Road 25 joins the concurrency. Then all four routes turn northeast towards downtown Delphi. When in downtown Delphi SR 25 leaves the concurrency on a northeast route as US 421/SR 18/SR 39 turn southeast. South of Delphi SR 18 leaves the concurrency with US 421 and SR 39\. SR 18 heads due east towards Flora where SR 18 has an intersection with State Road 75. SR 18 heads east towards Galveston passing through a concurrency with State Road 29. In Galveston SR 18 has an intersection with U.S. Route 35. Then just east of Galveston SR 18 has an intersection with U.S. Route 31.

The generalizing variants also guarantee global serializability without distributing local concurrency control information (each database has the generalized autonomy property: it uses only local information), while relaxing CO constraints and utilizing additional (local) information for better concurrency and performance: ECO uses knowledge about transactions being local (i.e., confined to a single database), and MVCO uses availability of data versions values. Like CO, both generalizing variants are non-blocking, do not interfere with any transaction's operation scheduling, and can be seamlessly combined with any relevant concurrency control mechanism. The term CO variant refers in general to CO, ECO, MVCO, or a combination of each of them with any relevant concurrency control mechanism or property (including Multi-version based ECO, MVECO).

North Dakota Highway 13 has its western terminus in Emmons County with ND 1804 and travels east about thirteen miles before entering Linton and beginning a concurrency with US 83.

Oz contains most of the concepts of the major programming paradigms, including logic, functional (both lazy evaluation and eager evaluation), imperative, object- oriented, constraint, distributed, and concurrent programming. Oz has both a simple formal semantics (see chapter 13 of the book mentioned below) and Oz is a concurrency-oriented language, as the term was introduced by Joe Armstrong, the main designer of the Erlang language. A concurrency-oriented language makes concurrency easy to use and efficient. Oz supports a canonical graphical user interface (GUI) language QTk.

A short distance later, they intersect the western terminus of CR 396 and then CR 394 in close succession. Approximately later, they intersect CR 73\.

At Columbus, US-160 begins a concurrency with U.S. Route 69, which goes east to Crestline, then north to Frontenac, Kansas. Also at Crestline, it picks up a second concurrency with U.S. Route 400, which goes north and ends just south of Pittsburg, Kansas. After Frontenac, it turns east and enters Missouri.

This bridge is just south of the Fishing Creek Dam. Just after the bridge, the concurrency intersects US 21, which joins them. Immediately, they enter Great Falls. SC 97 departs the concurrency and travels along the northern edge of the city limits of the town until it intersects SC 99 (Chester Avenue).

Continuing north, Route 5 has a short concurrency with Route 7, and it continues to North Smithfield. Route 5 crosses the Route 146 expressway without an interchange and terminates at the Massachusetts state line, though the northernmost Route 5 shields are around Route 102 at the south end of the Route 146A concurrency.

The northern terminus of SR 221 was not moved, resulting in a concurrency between SR 11 and SR 221 that existed until at least 2007.. By 2011, new signage had been installed indicating that SR 221 was truncated to the intersection of West Road and East Road, eliminating the concurrency with SR 11.

When the road was designated as an autobahn, the B 41 designation remained. The concurrency is indicated on all distance signs along the A 623, a rarity for German roads. The concurrency continues a further three junctions to the east along the A 8\. There is no junction 6 along the A 623\.

SH-58 continues north, meeting US-60 again near Ringwood. It then has a brief concurrency with State Highway 45 near Helena. Near Jet, it overlaps U.S. Highway 64 and SH-8. North of Cherokee, the Alfalfa County seat, US-64 splits off and State Highway 11 joins the three-route concurrency.

At this intersection, SR 19 departs the concurrency to the south, while SR 29 joins. The concurrent highways circle around the Laurens County Superior Court. At Washington Street, US 319/SR 31 also joins the concurrency. The five highways cross over the Oconee River on the Herschel Lovett Bridge and enter East Dublin.

Vernon is the site of a wrong-way concurrency at the intersection of NJ 94 and CR 517 in McAfee.

In Powell, they intersect and have a short concurrency with SR 131 before leaving Powell and crossing into Anderson County.

It's more mathematically natural to refer to these equations as concurrency equations, but photogrammetry literature does not use that terminology.

At the southern terminus of the concurrency, NY 364 shifts from an east-west route to a north-south roadway.

In 1993, the concurrency with US-183 was removed from the route. The route has not been modified since 1993.

The freeway ends to the north, near Laconia Airport, and NH 11 splits off from US 3 after a concurrency.

Then, they cross over the Oconee River on the LCPL Melvin Poole Memorial Bridge into Montgomery County. In Mount Vernon is an intersection with US 221/SR 56 (Railroad Avenue). The concurrency travels through nearby Ailey and enters Higgston. Here is an intersection with SR 15/SR 29 (James Street), which join the concurrency.

The highway passes through woodland and crosses over a railroad track. The concurrency ends at an intersection with SR 669 turning towards the east and SR 93 continuing towards the south. The highway heads east through woodland, with some farmland and houses. SR 669 begins a concurrency with SR 555, heading towards the north-northeast.

This intersection also marks the western terminus of Bob White Avenue. Two blocks later, the concurrency begins to travel around the town square. On the east side of this square, SR 62 departs the concurrency. The concurrent highways continue northward, crossing over some railroad tracks of Norfolk Southern Railway, and intersect SR 62 Byp.

Upon leaving Alfalfa County, US-64 passes into Grant County. The first town the highway passes through in Grant County is Nash, where it begins a concurrency with SH-132. This concurrency lasts for before SH-132 splits away. east of this junction, US-64 intersects US-60 and US-81 in a T junction.

Right after this intersection, the concurrency travels along the northeastern edge of Sheffield. They pass administration offices of the Tennessee Valley Authority (TVA). The five-highway concurrency passes offices of the Alabama state troopers and then the TVA Muscle Shoals Reservation and Wilson Dam. The highways curve to the northwest and enter Sheffield proper.

Just under later, US 129/US 441/SR 24 join the concurrency on the northeastern corner of Walton Park. The six routes head to the northeast, past Hill Park, before reaching downtown. Once in downtown Madison, SR 83 leaves the concurrency and travels to the northwest, toward Monroe. It passes through the town of Bostwick.

Then north of Linton SR 54 turns west toward Dugger. SR 59 heads north passing through the east side of Jasonville. SR 59 heads north from Jasonville towards Clay City where SR 59 has a concurrency with State Road 246. During the concurrency there is an intersection with State Road 157 in downtown Clay City.

Right after entering Caddo County, it has a concurrency with State Highway 58, and then it meets State Highway 146 near Binger.

The intersection with Anderson Avenue marks the beginning of US 79's long concurrency with SR 76, while the overlaps with SR 19 and US 70/SR 1 both end at the intersections with Jefferson Street and East Main Street, respectively. US 79/SR 76 begins a concurrency with US 70A at that point.

However, if contention for data resources is frequent, the cost of repeatedly restarting transactions hurts performance significantly; it is commonly thought that other concurrency control methods have better performance under these conditions. However, locking-based ("pessimistic") methods also can deliver poor performance because locking can drastically limit effective concurrency even when deadlocks are avoided.

The highway passes through farmland and begins a concurrency with SR 37, on the south side of Mount Blanchard. The concurrency heads north through Mount Blanchard, before SR 103 turns due east, just north of the town. SR 103 heads east, until a sharp turn due north. Followed by a second turn due east.

Then, SD 10 curves to the southeast and then travels through an area that has a lot of lakes. It travels just south of Sixmile Lake and then just south of Cottonwood Lake. Just south-southeast of the appropriately-named Lake City, the highway begins a concurrency with SD 25\. This concurrency is just under .

It crosses over part of Lake Hartwell on an unnamed bridge. A short distance later, it begins a concurrency with SC 187 at the Portman Shoals Intersection. The two highways cross over another part of the lake on the Calvin Wesley Belcher Bridge. It then enters West Gate, where SC 187 leaves the concurrency.

This would remain the case until 1995, when the SR 756 concurrency was removed from SR 505, resulting in SR 756 having a new eastern terminus where it currently does at SR 505\. In addition, SR 505 was re-instated to its 1937-1940 status of being free of a concurrency for its entire length.

The 1978 dissertation by David P. Reed which quite clearly describes Multiversion concurrency control (MVCC) and claims it as an original work.

Petri nets are an attractive and powerful model for reasoning about asynchronous circuits. However, Petri nets have been criticized for their lack of physical realism (see Petri net: Subsequent models of concurrency). Subsequent to Petri nets other models of concurrency have been developed that can model asynchronous circuits including the Actor model and process calculi.

The highway passes through the Hoosier National Forest and an intersection with SR 650. Southwest of Bedford US 50 begins a concurrency with SR 37.

At Morgan's Corner, the US 158 concurrency ends, and US 17 crosses the Pasquotank River into Camden County before heading north into Virginia.

The H-13 concurrency was removed in 2004 when the northern segment of H-13 along Miners Castle Road was redesignated H-11.

Versions numbered 0.4.9x are preview releases for version 0.5.0. The most noticeable improvement is undo support, using the adOPTed algorithm for concurrency control.

Following the old US 521 mainline route, this business loop, in concurrency with US 601 Business, goes through downtown Kershaw, via Hampton Street.

The library has been tested in various applications, including database benchmarks, 2D segment tree, 2D interval tree, inverted index and multiversion concurrency control.

After crossing LA 1, LA 107 runs parallel with it for to Cocoville before the two join in a northward concurrency toward Marksville.

Jamestown Road continues northeast as SR 5 beyond SR 199; westbound SR 5 joins SR 199 in a short concurrency west toward Richmond.

The US 1 concurrency south of Hunting Park Avenue was removed, with US 1 shifted to an alignment further to the west concurrent with US 13 Byp. US 13 was also split into a one-way pair along Robbins and Levick streets. The concurrency with US 1 along Hunting Park Avenue was removed in the 1960s after that route was shifted to the Roosevelt Expressway; the PA 73 concurrency along Frankford Avenue was also removed. US 13 was also rerouted to use Church Lane and Baltimore Avenue between Yeadon and West Philadelphia instead of following MacDade Boulevard and Whitby Avenue.

The 1966 GDOT map was the first one to feature an inset of Brunswick. The concurrency with US 84 was indicated to begin at the current western end of the US 82 concurrency near Brunswick and continued to the US 341/SR 27 intersection in the city, where US 84 joined that concurrency. In Savannah, SR 26 Loop, the predecessor of I-516, was proposed on basically I-516's current path. In 1966, the portion of SR 26 Loop used for US 17/SR 25 was indicated to have been under construction from Ogeechee Road to Augusta Avenue.

Highway 103 begins on the border of the National Park Service's Buffalo National River at Highway 43 in Newton County near Ponca. The highway runs north into Carroll County to Osage and passes Stamps Store before forming a concurrency with US 412 to the west. Following this overlap, Highway 103 runs north through Conner and Rule before forming a concurrency with US 62 in Green Forest. The highway turns north, ending this concurrency near the historic Green Forest Water Tower after which the route continues north through unincorporated areas to terminate at Highway 21 in Oak Grove near the Missouri state line.

Once crossing the state line, US 331 immediately enters Florala, where it starts a concurrency with Alabama State Route 54 (SR 54) on the east side of town. The highway continues into downtown Florala, where SR 55 joins the concurrency (this intersection serves as a terminus for SR 54). US 331 continues northward to Opp, where it becomes concurrent with US 84 as a bypass around the eastern side of town. A business route of US 331 continues northward through town and rejoins US 331 north of Opp, just after US 84 leaves the concurrency with US 331.

Interstate 90 enters South Dakota in Lawrence County as a four-lane divided highway. It enters concurrently with U.S. Route 14, and passes through the town of Spearfish, where it shares another concurrency with U.S. Route 85 from exit 10 to exit 17. From there it passes several miles north and east of the tourist town of Deadwood before entering Meade County, going just to the west of Sturgis. Another concurrency is with South Dakota Highway 34 from exit 23 at Whitewood to exit 30, the west exit of Sturgis, where there starts a concurrency with SD 79.

The highway heads east through mostly farmland, before entering Sycamore. On the east side of Sycamore SR 103, begins a concurrency with SR 67\. In the center of the Village SR 67 turns due north onto SR 231, with SR 103 still heading east, concurrent with SR 231\. The concurrency leaves Sycamore and enter rural Wyandot County, where SR 231 leaves SR 103 heading due south. SR 103 crosses into Crawford County. The highway heads towards Chatfield, passing through a very short concurrency with SR 100 and an intersection with SR 19. In Chatfield SR 103, turns northeast concurrent with SR 4\.

NY 100 merges with NY 9A to form a concurrency carrying the names Saw Mill River Road and Briarcliff–Peekskill Parkway, parallel to the Taconic State Parkway. NY 9A exits off this highway along the Briarcliff–Peekskill Parkway, while NY 100 continues straight as Saw Mill River Road. NY 9A merges to form a brief concurrency with US 9 as the Croton Expressway in Ossining just south of the Croton River. The second concurrency between US 9 and NY 9A runs for 1.10 miles, with NY 9A leaving the Croton Expressway at NY 129 in Croton-on-Hudson.

The highway splits off to the east from here, sharing a three-mile (4.8 km) concurrency with US-277/281 and an interchange with Interstate 44 (which is also the Walters toll plaza of the H.E. Bailey Turnpike). Five miles (8 km) east of where this three-route concurrency breaks up, SH-5 turns south in Walters, with the mainline being taken over by State Highway 53. SH-5 heads east again toward Temple, where it has a brief concurrency with State Highway 65, and then turns southeast to pass through Hastings before ending at US-70 in Waurika.

One of the main challenges in building collaborative real-time editors is in concurrency control. The concurrency control technology used by CoWord is Operational transformation. Operational transformation (OT) can incorporate concurrent changes made to replicas of the same document. This means systems built with OT allow multiple users to make concurrent changes to the document and all changes will be incorporated.

DE 71 has an annual average daily traffic count ranging from a high of 29,685 vehicles at the north end of the DE 896 concurrency to a low of 4,533 vehicles at the DE 7 intersection. The portion of DE 71 between Middletown Warwick Road and the north end of the DE 896 concurrency is part of the National Highway System.

The route begins at an intersection with US 19/SR 3/SR 300 north of Thomasville, in Thomas County. It heads due north to a short concurrency with SR 188\. A little ways north of the end of the concurrency, the route enters Colquitt County. It continues heading north until it meets its northern terminus, and intersection with SR 111 southwest of Moultrie.

At SR 10, US 231 turns due west, concurrent with the state road. After , the concurrency ends, with SR 10 traveling south and US 231 continuing north. The highway then enters Porter County on a bridge over the Kankakee River. North of the Kankakee River, the route begins a concurrency with SR 2 at a four-way stop south of Hebron.

The concurrency with Route 111 ends in Ayer in Middlesex County at a rotary junction with Route 2A, where Route 110 begins a concurrency with Route 2A eastward into Littleton. In Littleton, Routes 110 and 2A cross the Fitchburg Line railroad tracks before meeting I-495 at Exit 30, beginning Route 110's long relationship with the interstate. At Route 119.

At this intersection, SR 215 leaves the concurrency to the south. After leaving the city, the concurrency travels to a northeastern direction and enters Abbeville, where is an intersection with US 129/SR 11 (Broad Street). Before leaving the city, they pass Riverside Cemetery. A little under after leaving the city, they cross over the Ocmulgee River into Dodge County.

SR 69/US 64/SR 15 continue west, cross the Tennessee River, and exits Savannah. It continues to Crump, where SR 22 joins the concurrency. Shortly afterwards, SR 69 separates and turns north alone, and goes through Morris Chapel. It continues north and enters McNairy County and immediately comes to another junction and concurrency with SR 22 and they enter Milledegeville.

State Route 343 (SR 343) was a short-lived state highway that existed in the northeastern part of the state. It was completely within Rabun County. Between June 1960 and June 1963, it was established on a concurrency with US 23, US 441, and possibly SR 15 from Tallulah Falls and Wiley. The entire path of this concurrency was paved.

There, it intersects US 280/SR 30/S 165 (2nd Street). At this intersection, SR 117/SR 165 head to the north on a very brief concurrency. After the concurrency ends, SR 117 travels through rural areas of the county and intersects SR 87 (Abbeville Highway), just before entering Eastman. In Eastman, they first meet US 341/SR 27 (Terry Coleman Parkway).

After passing over I-64, Blankenbaker Parkway narrows to two lanes in both directions and passes by the main campus of Southeast Christian Church, one of the largest churches in the United States. It forms a concurrency with KY 1819 at the northeast corner of the church property and carries this concurrency for to its northern terminus at US 60.

A section of the northern extension was marked on maps through 1933 as "under construction". That section was cancelled in favor of another routing near Mancelona. A short bypass of Six Lakes added about a mile to the length of the roadway in 1936. The M-131 concurrency was switched to a US 131 concurrency when the latter was extended in 1939.

In Tolland, Route 74 continues east through town, with a brief concurrency with Route 30. Just prior to the Willington town line, it crosses I-84. In Willington, Route 74 continues eastward, with a brief concurrency with Route 320 in the center of town, and continues into Ashford. In Ashford, Route 74 continues southeastward to its terminus at an intersection with US 44.

The concurrency ends after traveling north for at km 69.2 when Highway 51 continues west and Highway 656 continues east for before veering north. At km 90.8 Highway 656 travels through Landis. At km 91.1 Highway 656 turns onto Highway 13 from a north heading to an east heading. Highways 13, and 656 travel as a concurrency until km 92.6.

At Albatross, is an intersection with Route 39\. Approximately further west is an intersection with Route 97\. At Avilla, there is a concurrency with Route 37\. As the road approaches Carthage, the highway curves south, then curves west again to become Central Street. At Garrison Avenue, the highway begins a concurrency with Route 571 and the road becomes a wide boulevard.

IL 97 starts off in Springfield on East Clear Lake Avenue. It heads west, forming a concurrency with IL 125\. IL 97 splits off and north shortly after, entering Menard County. In Menard County, along a concurrency with IL 123 in New Salem, it passes Lincoln's New Salem State Historic Site near Petersburg, the home of Abraham Lincoln in the 1830s.

The RM of Canwood provides civic governance to Hawkeye, and Ordale, both located just north of Hwy 3. Shellbrook is located southwest of Shell Brook, at the junction of Hwy 240 and Hwy 3. Crutwell is a part of Shellbrook No. 493 RM south of the Hwy 55 – Hwy 3 concurrency. This concurrency at is the longest of the route.

About later, they curve to the east-northeast. Then, they enter Tallapoosa's city limits, where they have a very gradual curve to the east. In the main part of town, they have an intersection with SR 100 (Robertson Avenue), which joins the concurrency for a few blocks, until it turns off onto Alewine Avenue. Here, the concurrency curves to the east-southeast.

US 30 enters Ohio heading southeast, as a four-lane divided highway passing through rural farmland. The highway passes through southwestern Paulding County, before entering Van Wert County.

The concurrency with State Route 104 ends just south of Chillicothe, Ohio, at which point US 23 becomes an expressway. The route bypasses Chillicothe to the east, including a short concurrency with US 35 before once again becoming a divided highway near Kingston. It continues as such through Circleville to the southern edge of Columbus, at the southern junction of Interstate 270.

SR 137 travels through rural areas of the county and has a very brief concurrency with SR 240 in Tazewell. In the northeast, it enters Taylor County and crosses just northwest of the Taylor–Schley county line. Less than later is SR 90/SR 127\. The three highways have a brief concurrency to the north, until SR 137 splits off to the northeast.

At US 50, the concurrency with US 421 ends when it heads east concurrent with US 50\. SR 129 heads east concurrent with US 50 and leaves town, entering Versailles State Park. After passing through Versailles State Park, the concurrency endS when SR 129 turns north towards Batesville. The highway enters Batesville and ends at an intersection with SR 46.

DE 41 was removed from the DE 141 concurrency in the 1970s and was realigned to follow DE 2 east to an interchange with DE 141 in the 1980s, with the old alignment south of DE 2 becoming part of DE 62\. In 2015, the southern terminus was cut back to its current location, removing the concurrency with DE 2\.

Also in 1986, US 74 was extended west, from Asheville to Chattanooga, Tennessee. The routing extension starts at its former western terminus with US 70, going northerly, in concurrency with US 70, to I-240, where it overlaps briefly before joining US 19/US 23\. From Asheville, in concurrency with US 19/US 23, it goes through Canton, Lake Junaluska and Waynesville.

U.S. Route 25 Bypass (US 25 Byp.), in complete concurrency with State Route 67 Bypass (SR 67 Byp.), is the western half of the divided four-lane bypass, west around Statesboro, Georgia also known as "Veterans Memorial Parkway." The eastern half is US 301 Byp., which is in concurrency with SR 73 Byp. The entire length of US 25 Byp.

In downtown Lakeland are intersections with the western terminus of SR 11 Byp. (West Church Avenue) and the northern terminus of SR 11 Conn. (Pecan Street), before meeting SR 122 (West Main Street), which joins the concurrency. Approximately later, they intersect US 221/SR 31/SR 135, which join the concurrency. Immediately, SR 135 departs to the north-northwest on North Carter Street.

There is a rest area south of Chamberlain with an historical marker. To the west of the highway are afforded views of the Arm River valley.

In the central part of town is an intersection with US 23/US 341/SR 27\.

LA 415 begins at Interstate 10's exit 151 in West Baton Rouge Parish, west of Port Allen. Just north of the interchange, LA 415 begins a concurrency with LA 76. The two routes travel north as a four-lane undivided highway with a center turn lane. After LA 76 exits the concurrency, LA 415 continues north and widens to a divided highway.

The concurrency heads northwest into Jackson, where they head to the west for a short while. First SR 16, and then SR 36 join and then leave the concurrency. US 23/SR 42 resume their north-northwest routing, passing Sylvan Grove Hospital before leaving town. They curve to the west again, traveling through the town of Jenkinsburg, then enter Henry County.

Continuing north of the river, the highway twists to the northeast and passes through Uniontown. Just north of Uniontown, K-3 enters a concurrency with U.S. Route 54 (US-54) and turns west. The highways curve to the northwest, running through slightly wooded flat lands. K-3 leaves the concurrency with US-54 just east of the city of Bronson and turns north.

In 2012, the traffic on the route, measured in annual average daily traffic, was found to be between 130 and 2060 vehicles per day. Most of the traffic was present on the concurrency with US-54. K-3's concurrency with US-54 is included in the National Highway System, a system of highways important to the nation's economy, defense, and mobility.

At 286th Street, SD 19 begins a concurrency with U.S. Route 18 (US 18) for just over ; they split at 285th Street. Between 284th and 283rd streets, it briefly travels through the far eastern part of Hurley. At 277th Street, it begins a concurrency with SD 44\. This intersection is also the eastern terminus of County Road 24 (CR 24).

SR 1 then leaves Butler heading due north until it intersects DeKalb County Road 46, at which point the highway turns northwest. The route enter Hamilton and begins a concurrency with SR 427, heading northeast and passing Hamilton Lake. After , SR 1 leaves the concurrency heading due north. The highway then continues in that direction until reaching its northern terminus at US 20.

Most of the route of SR 300 in Albany is on the Liberty Expressway, a freeway-grade bypass of the city's downtown to the northeast. In the southeastern part of the city is an intersection with SR 133, which joins the concurrency, and the eastern terminus of SR 234\. Nearly later, the concurrency intersects US 19 Bus./US 82 Bus.

A number of networking and threading libraries are available, such as EiffelNet and EiffelThreads. A concurrency model for Eiffel, based on the concepts of design by contract, is SCOOP, or Simple Concurrent Object-Oriented Programming, not yet part of the official language definition but available in EiffelStudio. CAMEO is an (unimplemented) variation of SCOOP for Eiffel. Concurrency also interacts with exceptions.

Mississippi Highway 555 (MS 555) is a state highway in southwestern Mississippi. The route has two sections, both in Adams County. The first section starts at Ogden Road and travels northwestward to its terminus at US 61. The second section starts at the concurrency of MS 930 and MS 932 and the concurrency of US 61 and US 84 in Natchez.

In Rochester Township, PA 65 begins a concurrency with PA 18 as it enters the northbound lanes of PA 65 and exits on the southbound lanes. PA 18/PA 65 continue northward paralleling the Beaver River. In New Brighton, the PA 18/PA 65 concurrency ends when PA 65 makes a 90-degree-angle turn towards the northeast as 5th Street.

It then heads east towards Rochester, with an expressway segment beginning at Minnesota State Highway 56 and continuing east into Rochester. Once it enters Rochester, it has a concurrency with U.S. Route 52. After the concurrency, it continues through Rochester as a divided highway. After Rochester, the highway parallels Interstate 90 until Winona, where U.S. 14 gets picked up by U.S. Route 61.

US 129/441/SR 24 will later join these routes in yet another concurrency, although SR 83 leaves at Washington Street. After passing by the Madison Airport, US 129/441/SR 24 leaves the concurrency with US 278/SR 12 at the north end of the Madison Bypass, and turns northeast as it crosses a bridge over a railroad line.

SR 10 became US 68 in 1933. US 33 replaced SR 31 between Pomeroy and Columbus, in 1938, from Columbus to Marysville US 33 became concurrent with SR 31. The southern terminus was moved to Marysville in 1942, removing the concurrency with US 33. In 1951 the concurrency with US 68 was removed, making the northern terminus of SR 31 in Kenton.

It then intersects I-99 in Bedford County before reaching the eastern end of its concurrency with the Turnpike in Breezewood.

NC 28 starts at the Georgia state line in Macon County. From the state line, it follows a winding course northwards to Highlands. There it begins a concurrency with U.S. Route 64 (US 64) on the way northwest to Franklin. Following an interchange with US 23 and US 441, the US 64 concurrency ends and enters the downtown business district of the city.

This concurrency ends in Ripon, where a concurrency with WIS 23 begins. The highway runs north from the concurrent alignment shortly before it reaches Green Lake. While running north, WIS 49 runs through Berlin and many smaller communities before reaching an interchange at US 10. The highway runs concurrently with US 10, which is a freeway for most of its length.

In Walpole, NH 123 runs in a wrong-way concurrency with NH 12 north–south alongside the Connecticut River, the water body that represents the border between New Hampshire and Vermont. For the entire length of the NH 12/NH 123 concurrency, NH 123 South is, in reality, heading north on the compass while NH 123 North is traveling to the south.

A view of U.S. 50 (traveling west) near Albany, Ohio as it is about to leave the concurrency with SR 32 U.S. Route 33 during its brief concurrency with U.S. Route 50 and Ohio State Route 32 in Athens. East of Milford, US 50 becomes a two-lane highway as it travels through Hillsboro and Bainbridge before reaching the outskirts of Chillicothe.

The eastern section begins at an intersection with U.S. Route 421. SR 250 has a concurrency with State Road 62. Then SR 250 leaves the concurrency with SR 62 and then passes through intersections with State Road 129 and State Road 56.

The route crosses the St. Joseph River and enters the downtown business district of Montpelier. The road has a traffic signal and begins a concurrency with SR 576\. The concurrency heads east leaving the business district and ending residential areas.

SAP HANA manages concurrency through the use of multiversion concurrency control (MVCC), which gives every transaction a snapshot of the database at a point in time. When an MVCC database needs to update an item of data, it will not overwrite the old data with new data, but will instead mark the old data as obsolete and add the newer version.

North of Forest Park, the concurrency, now called Old Dixie Road has an interchange with the southern side of Atlanta's interstate loop, Interstate 285.

The South Dakota section of U.S. 18, other than the concurrency with Interstate 29, is defined at South Dakota Codified Laws § 31-4-141.

18–19 Simpson is featured on a New Hampshire historical marker (number 25) along the concurrency of Route 107 and Route 43 in Deerfield.

CO enforcement by itself is not sufficient as a concurrency control mechanism, since CO lacks the recoverability property, which should be supported as well.

A copy of any concurrency or nonconcurrency statements shall be made a part of the administrative record and referenced in the final guidance memorandum.

The highway enters from Colorado into Cheyenne County, and shares a seven-mile (11 km) concurrency through the town of St. Francis with K-27, the first north–south route intersected in Kansas. K-27 splits east of St. Francis and heads south toward Goodland, and US-36 then continues through Bird City and McDonald before intersecting K-25 in Atwood, the seat of Rawlins County. US-36 continues east through Decatur County, intersecting with US-83 in Oberlin before beginning a concurrency with K-383 in Norton County, a concurrency which runs for 12 miles (19 km) through the city of Norton, where it crosses US-283. K-383 splits in eastern Norton County and bends northeast toward Almena and the Nebraska state line, while US-36 enters Phillips County, picking up a brief concurrency with US-183 in Phillipsburg.

After crossing the Kiskiminetas River, PA 66 has entered Armstrong County and begins a concurrency with Pennsylvania Route 56 in Apollo. As they began their concurrency, PA 56/PA 66 were called Warren Avenue in Apollo. As PA 56/PA 66 enter the boro of North Apollo they are paralleling the Kiskiminetas River. In the village of North Vandergrift, the concurrency between PA 56 and PA 66 ends when PA 66 intersects PA 66 Alternate and PA 56 and PA 66 ALT begin their own concurrency into Vandergrift. As PA 66 continues to parallel the Kiskiminetas River, it is called Lincoln Avenue. While paralleling the Kiskiminetas River, PA 66 has snake like curves. In Leechburg, PA 66 becomes Market Street, 3rd Street, and Pershing Avenue. As PA 66 exits Leechburg it is not paralleling the Kiskiminetas River.

As PA 208 enters Mercer County, it turns east-northeast and meets US 19 at the village of Leesburg about later. The routes briefly overlap northward, and then PA 208 continues east-northeastward. About from Leesburg, the route is joined by PA 258 north of the Grove City Premium Outlets, and the concurrency then interchanges with I-79 (exit 113) immediately thereafter. The concurrency ends later at the village of London – prior to the interstate, this was a simple junction between PA 208 and PA 258. PA 208 continues east- northeast about to the borough of Grove City, where it meets PA 58 and PA 173. This point is the westernt terminus of the PA 58/PA 173 concurrency, and the southern terminus of the PA 173/PA 208 concurrency; also at this point, the north- and southbound lanes of the PA 173/PA 208 concurrency are split on one- way streets through the downtown area of Grove City, heading northward for about . Another later, the concurrency ends, and PA 208 continues eastward, leaves the borough, and meets the county line later. PA 208 enters Venango County, and later intersects with PA 8 in the borough of Barkeyville. The route continues eastward where it passes over I-80 before entering the borough of Clintonville later; here the route intersects with PA 308.

After passing under the turnpike, US 127 has a brief concurrency with US 20 and then enters Michigan to the north in rural Lenawee County.

MVCC is particularly adept at implementing true snapshot isolation, something which other methods of concurrency control frequently do either incompletely or with high performance costs.

However, the official definition of the highway contains an unsigned concurrency with US-59 to the point where it crosses the state line into Kansas.

The concurrency enters Tybee Island and meet their eastern terminus, an intersection with Butler Avenue (which continues after the terminus), Tybrisa Street, and Inlet Avenue.

The route begins at an intersection with US 129/SR 11/SR 76/SR 125 in Nashville. It heads southeast to an intersection with SR 64/SR 135 north of Lakeland, where SR 64 begins a concurrency to the east. Farther to the east, SR 64 leaves the concurrency to the northeast.

As Highway 6 leaves Guelph and heads northwards through Wellington County, it narrows to two lanes and passes through farmland. The route meanders northward for before entering Fergus, where it meets County Road 18 and County Road 19\.

For applications that require parallel computing on supercomputers, the degree of concurrency offered by a numerical method becomes relevant. In view of the challenges from exascale computing systems, numerical methods for initial value problems which can provide concurrency in temporal direction are being studied. Parareal is a relatively well known example of such a parallel-in-time integration method, but early ideas go back into the 1960s.

From U.S. Route 97, including the concurrency with U.S. 97 Business, to its departure from OR 140, including the concurrency, OR 39 consists of concurrent parts of the Klamath Falls-Malin Highway No. 50 (see Oregon highways and routes) and the Klamath Falls-Lakeview Highway No. 20. At that intersection, OR 39 then turns due south, and is now known as the Klamath Falls-Malin Highway.

After traveling six miles east, the highway curves to the east-northeast for about five miles to parallel nearby railroad tracks. The highway reaches Verona and begins a concurrency with ND 1. The concurrency heads due south for six miles before heading west along the LaMoure-Dickey county line for about half of a mile. After this, the highways curve south once more and enter Dickey County.

They intersect SR 17 Business (known locally as Poplar Drive to the south and Tignall Road to the north). Here, SR 44 departs the concurrency to the north. After this intersection, US 78/SR 10 begin to curve to the south-southeast. They curve to the east and intersect SR 17, where the concurrency turns right, and all three highways travel to the south-southeast.

Entering Greers Ferry AR 92 begins at US 64 in Plumerville. The route crosses Interstate 40 and continues north through Conway County. A concurrency begins with AR 124 in Springfield and also AR 9 north of Springfield. The AR 9/AR 92/AR 124 concurrency continues north to Center Ridge, when AR 124 turns west, AR 9 heads north, and AR 92 turns east.

Farther into Gainesville is SR 53 Connector/SR 60 (Candler Road/Queen City Parkway). In the main part of the city, US 129/US 129 Business/SR 11 (Athens Highway) meets the concurrency. US 129/SR 11 heads south toward Jefferson, while US 129 joins the concurrency through the rest of the city. Meanwhile, US 129 Business/SR 11 heads north into the heart of Gainesville.

As Leslie Lamport (2015) notes, "While concurrent program execution had been considered for years, the computer science of concurrency began with Edsger Dijkstra's seminal 1965 paper that introduced the mutual exclusion problem. ... The ensuing decades have seen a huge growth of interest in concurrency—particularly in distributed systems. Looking back at the origins of the field, what stands out is the fundamental role played by Edsger Dijkstra".

SR 69 begins a concurrency with SR 66, heading northeast. Soon after the concurrency begin it ends with SR 66 heading due east and SR 69 still heading northeast. At an intersection with the western terminus of SR 68, SR 69 heads due north, before turning northwest. The highway makes a sharp curve heading northeast towards Griffin where it terminates at Interstate 64 (I–64).

From US 31, SR 18 heads east towards Converse passing through a concurrency with State Road 19. SR 18 then heads through Converse, after Converse SR 18 has a concurrency with State Road 13. SR 18 turns southeast towards Marion passing through Sweetser. In Marion eastbound SR 18 is on a Fourth Street and westbound SR 18 is on Third Street and Second Street.

US 78/SR 8 travel due east to an intersection with the southern terminus of Polk Road, where they begin to curve to the east-northeast. They travel through White City, curving back to the northeast. After a very brief jaunt to the east, the concurrency curves to the east-northeast and enters Douglasville. In town, they intersect SR 5 (Bill Arp Road), which joins the concurrency.

US 30 has an interchange with I–77, this interchange is also the eastern end of the US 62 concurrency. East of I–77, US 30 has a short concurrency with SR 43\. The four-lane divided highway with limited access ends at an interchange with Trump Avenue. US 30 heads north on Trump Avenue, as a four-lane highway with a center turn lane.

There, US 23 begins a brief wrong-way concurrency with I-75, then departs for a concurrency with Interstate 475, the western bypass of the Toledo metropolitan area. US 23 and I-475 are concurrent for the latter route's entire north-south portion, until I-475 departs in Sylvania to become an east-west aligned route. US 23 then continues northerly into Michigan as a freeway.

The route begins at Highway 96 in Hartford and runs north to form a concurrency with Highway 252 through Midland. Further north, the route has an Officially designated exception of through downtown Hackett. Slightly north of this exception, Highway 45 runs on the Hackett Creek Bridge and continues north to Bonanza. The route intersects Highway 253 and curves east to form a concurrency with US 71\.

About into Pawnee County, US-64 enters the county seat, Pawnee. Here, the route begins a concurrency with SH-18. The two highways head southeast out of town together for just over before SH-18 splits off to the south toward Lone Chimney. US-64 continues alone to the east for about before beginning another concurrency, this time with SH-99, on the outskirts of Cleveland.

The highway intersects US 82, forming a concurrency east for five blocks. After the concurrency ends Highway 133 continues north to North Crossett where it meets Highway 133 Spur near an industrial area and Highway 52. The highway continues through wooded areas as an alternating passing lane highway, including a junction Highway 189 near Old Milo. Continuing north the route terminates at Highway 8 near Fountain Hill.

East of Zuber, the road intersects SR 326, which originally had a short concurrency, but now directly crosses US 301-441. South of the intersection with CR 329 is an interchange with U.S. Route 441 between Sparr and Lowell, where the US 301-441 concurrency ends. US 301 moves northeast towards Waldo, Starke, and Jacksonville taking SR 200 with it, while US 441 moves northwest.

In Clayton, there is a concurrency with SH 2 which to the south is the better through travel route from Antlers. The town has a monument that indicates that the highway was built by convict labor in 1925. From Clayton, US 271 takes on an easterly trajectory, passing Tuskahoma and Albion, before turning northward prior to Talihina. In Talihina, there is a brief concurrency with SH 63.

One block later, it intersects US 27 Business/SR 1 Business (South Main Street). The three highways travel concurrently to the north through downtown. On the way, they pass east of Blakely Cemetery and intersect SR 62 (Columbia Street), which joins the concurrency. The four highways travel around the city square, with SR 62 departing the concurrency on the east side of the square.

Its interchange has access to both SR 13 and SR 53\. Farther into Gainesville is SR 53 Connector/SR 60 (Candler Road/Queen City Parkway). In the main part of the city, US 129/US 129 Business/SR 11 (Athens Highway) meet the concurrency. US 129/SR 11 head south toward Jefferson, while US 129 joins the concurrency through the rest of the city.

At Leesburg, SR 68 and US 411 intersect and begin a concurrency as they cross Weiss Lake and Weiss Dam and approach Centre. SR 68 diverts from US 411 and begins a concurrency with SR 9 as the two highways again cross the lake, diverting from each other at Cedar Bluff. From there, SR 68 travels to the northeast as it approaches the Georgia state line.

As described below, work has continued in investigating appropriate denotational semantics for aspects of programming languages such as sequentiality, concurrency, non- determinism and local state. Denotational semantics has been developed for modern programming languages that use capabilities like concurrency and exceptions, e.g., Concurrent ML,John Reppy "Concurrent ML: Design, Application and Semantics" in Springer-Verlag, Lecture Notes in Computer Science, Vol. 693. 1993 CSP,A.

Optimistic concurrency control (OCC) is a concurrency control method applied to transactional systems such as relational database management systems and software transactional memory. OCC assumes that multiple transactions can frequently complete without interfering with each other. While running, transactions use data resources without acquiring locks on those resources. Before committing, each transaction verifies that no other transaction has modified the data it has read.

ND 40 begins at a junction with US 2 south of Tioga, in eastern Williams County. It passes through that town and then begins a brief concurrency with ND 50 in McGregor. ND 40 and ND 50 together enter Burke County. ND 40 leaves the concurrency in Battleview by turning northward to ND 5 in Columbus, and then turns west to run concurrently with that highway.

U.S. Route 97 Spur (US 97 Spur) is a long spur route that connects US 97 north of the terminus of the US 2 concurrency to US 2 east of the end of the concurrency, completely located in Orondo, a community in Douglas County. The busiest section of US 97 Spur in 2007 was at the US 97 intersection, with a daily average of 250 motorists.

Mile zero at the Indiana-Illinois border. SR 26 is a two-lane highway that connects with Illinois Route 9 and SR 352 at the Illinois state line in western Warren County. The road heads east passing through agricultural land, before turning south concurrent with U.S. Route 41 (US 41). The concurrency heads southeast, before SR 26 leaves the concurrency heading east towards Lafayette.

Shifting a bit further away from the coast it eventually enters the town of McCormick. From McCormick, it leaves SC 28, and briefly joins a concurrency with U.S. Route 378 until that route breaks away at East Gold Street. From there it continues northeasterly into the woods. After crossing the McCormick-Greenwood County Line, US 221 joins a concurrency with South Carolina Highway 10 south of Bradley.

Business US 60 in Monett begins at Kyler Street (in a concurrency with Route H) in south central Monett. It crosses over a viaduct, where Kyler Street becomes 13th Street and joins the old alignment of US 60 in the city. At Cleveland Street, the concurrency with Route H ends and the business route turns east, eventually rejoining the main route east of the city.

Business US 60 in Poplar Bluff begins in the northwest corner of the city at the interchange of US 60 and US 67 (Future I-57). It begins in a concurrency with Business US 67. At Pine Boulevard, Business US 60 leaves the concurrency, turning east. Pine Boulevard curves to run northeast through the city, and the business route rejoins the main route east of the city.

US 6/US 50 travel concurrently to Grand Junction, Colorado. I-70/US 6 run mostly parallel between here and just east of Idaho Springs, Colorado with the two routes, joining, separating and crossing over each other several times in this span. ;Colorado : northwest of Minturn (as part of a concurrency with I-70). : east of Empire (as part of a concurrency with I-70).

The highway continues south along the concurrency until it reaches Luck, where it runs east from. In Cumberland, it follows a short concurrency with U.S. Route 63. After passing Highway 25 and an interchange with U.S. Route 55, it passes through Rice Lake. It continues east from Rice Lake, passing through a few villages and unincorporated communities before terminating at Highway 40 in Weirgor.

A new direct routing south to the QEW along Bronte Road was established. During the spring of 1974, the route was extended north to Highway 89\. A concurrency with Highway 24 was established east of Ospringe to Trafalgar Road, which the route followed north to Highway 9\. The entire route of Highway 104 became part of Highway 25, and a concurrency with Highway 9 created.

At Shore Road, the state route curves sharply to the north and its name changes to Douglas Highway. It now parallels the Jordan River where the road passes many small businesses and sand pits. SR 184 shares a concurrency with SR 204 in this area. After the concurrency, the road passes the town offices of Lamoine and begins to start curving to the northeast.

The route begins at the western terminus and heads east to Falkner, where it runs concurrently with MS 15 and heads south to Ripley. There, it turns east again, leaving MS 15 for a short overlap with MS 2 and MS 4\. Leaving the concurrency, it travels south through Dumas to Pleasant Ridge. It then joins MS 30 for a short concurrency between Pleasant Ridge and Graham.

This intersection also doubles as the terminus of the NY 78 and NY 98 concurrency as NY 98 proceeds south on NY 77's right-of-way. NY 78 northbound along the wrong-way concurrency through Java with NY 98 southbound NY 78 bends northwest on Main Street and out of Java Center as a two-lane rural roadway through the town of Java.

AR 98 begins at US 82 west of Waldo. An officially designated exception begins at US 371 (Olive Street) in Waldo, and a concurrency of . Continuing east past the National Register of Historic Places-listed Waldo Water Tower, AR 98 intersects AR 98B (its only business route) in McNeil. The highway forms a concurrency with US 79 briefly north before turning east then south.

Here, SR 16's and SR 212's eastbound lanes depart the concurrency and SR 83 departs the square and the concurrency. SR 83 then leaves Monticello, passing the Hunter Pope Country Club, and continues to travel to the northeast. On the way, the route has an intersection with SR 142 in Shady Dale. Shortly after, it reaches its northern terminus at the Morgan County line.

SR 247 begins in Maury County at an intersection with SR 50 in Williamsport. It heads east through rural farmland and slightly hilly terrain, running parallel to the Duck River, to Santa Fe, where it has a short concurrency with SR 7. The highway leaves the river and passes northeast through mountains for several miles to pass through Theta before reentering farmland and having over a long concurrency with SR 246 just south of Burwood. SR 247 the enters Spring Hill and passes along the northern edge of Spring Hill Manufacturing before passing through downtown, where it has an extremely short concurrency with US 31/SR 6.

K-61 passes through the towns of Preston, Turon, Langdon (unincorporated) and Partridge, while paralleling a line of the Union Pacific Railroad, then beginning a six-mile (10 km) concurrency with US-50. It shares a short concurrency with K-14 and K-96 near South Hutchinson. After breaking to the northeast from US-50, K-61 passes through the east side of Hutchinson (Where it is signed locally as the Ken Kennedy FreewayGoogle Maps). It bypasses Medora (unincorporated), Inman, and Groveland before ending at I-135 and US-81 south of McPherson. Its last two miles share a "wrong-way" concurrency with US-81 Business.

The route continues its concurrency with PA 381 for another until it splits at Jones Mills. As soon as the concurrency ends, the route has another short concurrency with PA 31 from Jones Mills to the town of Donegal. Continuing on PA 31 will take you to the Pennsylvania Turnpike, where the Donegal Exit (Exit 91) lies very close to PA 711 (Signage on the Turnpike shows this as a route to PA 711). After PA 711 itself passes over the Pennsylvania Turnpike, the route passes through Donegal, and heads northeast to the village of Stahlstown, where it has an intersection with PA 130.

After re-entering Texas, US 62 continues east through Seminole where US 180 heads east towards Lamesa and US 62 turns north northeast along a concurrency with US 385 through Seagraves and Brownfield. In Brownfield, US 62 picks up US 82/US 380 from Plains for a four-way concurrency for about two blocks, where US 380 heads east toward Tahoka. US 385 drops off approximately later to head northwest toward Levelland. US 82 continues as a concurrency with US 62 into Lubbock. US 62 splits from US 82 and joins with State Highway 114 (SH 114) for approximately along the campus of Texas Tech University's southern border.

The South Dakota section of US 81, with the exception of a concurrency with US 14, is defined at South Dakota Codified Laws § 31-4-179.

Established in 1960 as a renumbering of US 15A along Columbia and Franklin Streets, in concurrency with US 501 Business. It was decommissioned between 1985-1987.

The route continues on northward to Greenwood, where it enters the city's southwest side, ending at the US 25 Bus./US 178 Bus./SC 34 concurrency.

U.S. Route 29 Connector is a connector route, in concurrency with SC 20 Connector, along Anderson Highway. It connects US 29 with SC 20, in Williamston.

Interstate Business Loop 90 ends at exit 180A on I-90/US 218, the latter of which leaves it's concurrency with I-90 at exit 180B.

US 15 exits onto Sheppards Road and has a brief concurrency with US 460 Business north to the northern end of US 15 Business (Third Street).

It begins a concurrency with I-44 at that route's western terminus, and the two routes travel north, crossing the Red River into Oklahoma near Burkburnett.

Established in 1960 as a renumbering of US 501A along Columbia and Franklin Streets, in concurrency with US 15 Business. It was decommissioned between 1985-1987.

On August 13, 1962, the road was relocated in Karnack, creating a concurrency with FM 1915, which became part of SH 43 on June 1, 1967.

In Bushnell, US 301 becomes Main Street. The first main intersection there is County Road 476 (Seminole Avenue), a road that runs from northwestern Hernando County to north of Webster. CR 48 shares a hidden concurrency with US 301, that's not so hidden when it turns onto CR 476. Sumter County Road 48 runs north towards West Belt Avenue, taking the DeSoto Trail with it, while US 301 turns east on East Noble Avenue, and crosses CSX's S-Line, where it once shared a brief concurrency with CR 48 until that designation turned south onto Florida Avenue on its way to Lake County. From there, Route 301 shares an even shorter concurrency with County Road 476, until it curves back north. US 301 passes by the ground of Lake-Sumter Community College's Sumter Campus in Sumterville. Shortly after this, US 301 intersects County Road 470, and both roads share a concurrency. The north end of SR 471 is encountered after this, and then the concurrency with County Road 470 breaks away to head east towards Okahumpka. In Coleman US 301 intersects with an abandoned railroad right-of-way that carried the SAL/Amtrak Silver Meteor until 1988.

The concurrency ends later inside the city limits of St. Clair. The road briefly joins former U.S. Route 66, turns a corner, and ends at Interstate 44.

On August 2, 2017 the new St. Croix Crossing bridge opened and 36 now uses this bridge to cross into Wisconsin, eliminating its concurrency with MN 95.

The road then passes Fraser and Winter Park without major intersections. About later, US 40 starts a concurrency with I-70. About later, I-70 splits off.

Some concurrent programming models include coprocesses and deterministic concurrency. In these models, threads of control explicitly yield their timeslices, either to the system or to another process.

The native C API is an extensive library functions for all database operations. Timestamps, concurrency control, transaction control, database configuration, data navigation, and data changes are supported.

The highways travel concurrently to Tulsa. : in Tulsa. The highways travel concurrently through Tulsa. : in Tulsa. I-444 and US 64 have a hidden concurrency through Tulsa.

Table level locking and multiversion concurrency control are implemented. The 2-phase commit protocol is supported as well, but no standard API for distributed transactions is implemented.

PA 42 was widened to a divided highway between the south end of the US 11 concurrency and the I-80 interchange in Bloomsburg in the 1960s.

The north–south concurrency with US 33 was added in the early 1970s and the southern terminus was moved to Fortville in the mid-to-late 1970s.

It was called Elverson Road, Twin Valley Road and Haycreek Road. In Birdsboro, PA 82 was called Furnace Street and had a small concurrency with PA 724.

Signage along US 9 shows CR 547 leaving the concurrency at 9th Street. Along this stretch, CR 547 runs through wooded areas of homes, crossing CR 526.

On April 1, 1970, the southern end of the highway was rerouted. The section along Guelph Line was decommissioned and the concurrency with Highway 5 was removed.

This often turns transactions into distributed ones, if they themselves need to span multi- processes. In these cases most local concurrency control techniques do not scale well.

After passing through Willard, it sets out across the Pedernal Hills. In Encino, it begins a concurrency with US-285. Just after crossing into Guadalupe County, US-54 joins the concurrency. The three highways pass through Vaughn and then go their separate ways, with US 285 heading southeast towards the direction of Roswell, US 54 heading northeast towards both Santa Rosa and Interstate 40, and US 60 heading east towards Clovis.

SR 122 begins at an intersection with US 19/US 84/SR 3/SR 38/SR 300 (Thomasville Bypass) in Thomasville, in Thomas County. The road heads to the northeast, passing the Thomasville Regional Airport, and travels through rural areas of the county until it reaches the town of Pavo. There, it has a brief concurrency with SR 33\. The concurrency ends at the Thomas–Brooks county line.

Then, it continues to the southeast and curves to the east-northeast, to enter Americus. In the northern part of the city, it begins a concurrency with US 19/SR 3 (North Martin Luther King Boulevard). The three highways travel south-southeast, curve to the southwest, and reach West Lamar Street. At this intersection, SR 30 departs the concurrency by turning left onto US 280/SR 27/SR 49\.

In the main part of the city is an intersection with SR 377 (Lee Street). After passing Oak Grove Cemetery, SR 49 departs to the north on Tripp Street. Less than later, SR 27 departs to the east on Vienna Road, while US 280/SR 30 curve to the southeast. The concurrency passes Brickyard Plantation Golf Club and enters Leslie, where SR 195 (North Bailey Avenue) joins the concurrency.

US 280/SR 30 pass the Jerry Bacon Recreational Park. Continuing east-southeast, they enter Pembroke. At Main Street, SR 67 (from the left side of the concurrent highways) and SR 119 (from the right side) both join the concurrency. One block later, at College Street, those two highways depart the concurrency, traveling in opposite directions from how they joined (SR 67 turns right, while SR 119 turns left).

The road turns to the north and winds through forested areas with occasional residential development. The route curves to the northwest and comes to an intersection with KY 3. At this point, KY 321 turns east to form a concurrency with KY 3, passing through more rural areas with some development including Highlands Regional Medical Center. The road forms a short concurrency with KY 3051 before it curves to the north.

At this intersection, SR 90 joins the concurrency. After traveling on the west side of both Crisp Regional Hospital and the Crisp County-Cordele Airport, the three highways leave the city to the north and enter Dooly County. They enter Vienna, where they intersect SR 27 (Union Street). At this intersection, SR 90 departs the concurrency to the west-northwest, while US 41/SR 7 continues to the north.

In Union County, it passes by the Knoxville Dragstrip before having an intersection and concurrency with SR 61 in Paulette. They then have a short concurrency with SR 144 before entering Maynardville. They go through downtown before SR 61 separates and goes east, then SR 33 goes north and leaves Maynardville. It then meets the eastern end of SR 170 in Hickory Valley before crossing Norris Lake and into Claiborne County.

After US 41, SR 352 leaves Boswell, heading east towards Oxford, passing through farmland and parallel to the Kankakee, Beaverville and Southern Railroad track. SR 352 enters the town of Oxford and begins a concurrency with SR 55. The concurrency heads east before turning north onto Justus Street. SR 55 and SR 352 head north on Justus Street for a block before turning east onto McConnell Street passing downtown Oxford.

The interpreter standard library also provides a seamless interface between Java and AmbientTalk objects, called the symbiosis. The language's concurrency features, which include support for futures and event-loop concurrency, are founded on the actor model and have been largely influenced by the E programming language. The language's object- oriented features find their influence in languages like Smalltalk (i.e. block closures, keyworded messages) and Self (prototype-based programming, traits, delegation).

At this point, SR 130 ends and US 6 turns north to run in concurrency with SR 51 to the junction with Interstate 80/Interstate 94 in Lake Station. The concurrency with US 6 ends here and SR 51 continues north a short distance to its northern terminus at US 20. No segment of State Road 51 in Indiana that is included in the National Highway System (NHS).

All three routes head southeast, until SR 18 turns due east. SR 18 heads east towards Brookston, passing through an intersection with U.S. Route 231 and an interchange with Interstate 65 (I-65). In Brookston SR 18 has a concurrency with State Road 43. From Brookston SR 18 heads east towards Pittsburg, just west of Pittsburg SR 18, begins a concurrency with U.S. Route 421, and State Road 39.

The two routes form a concurrency and together head northeast into Sandy Township. While the Tuscarawas River heads south towards Dover, SR 212 now begins to follow the Conotton Creek which it will for the remainder of the route. After , SR 212 breaks off of the SR 800 concurrency, the latter heads north towards Mineral City. SR 212 crosses the Conotton Creek and parallels it through Fairfield and Warren townships.

The northern SH-82 begins at Interstate 40 exit 297 just south of Vian. In Vian, SH-82 meets US-64. Six miles north of Vian, SH-82 runs through Box before meeting SH-100 and forming a concurrency with it on the east shore of Lake Tenkiller. After splitting from SH-100, SH-82 heads through Keys before forming another concurrency, this time with US-62 and SH-10.

In 1938, another rerouting moved State Route 117's western terminus to its current terminus. Its route through Mendon was recertified as State Route 707. In 1950, State Route 117 was once again routed in a concurrency to Bellefontaine, this time with U.S. Route 33 (which had replaced State Route 32 in 1938). This concurrency was ended in 1968, and State Route 117 was truncated at its current eastern terminus.

Akka is a free and open-source toolkit and runtime simplifying the construction of concurrent and distributed applications on the JVM. Akka supports multiple programming models for concurrency, but it emphasizes actor- based concurrency, with inspiration drawn from Erlang. Language bindings exist for both Java and Scala. Akka is written in Scala and, as of Scala 2.10, the actors in the Scala standard library are deprecated in favor of Akka.

At an interchange with SR 50 (Williamsport Pike), the concurrency briefly re- enters the city before leaving again. The concurrency curves to the east- southeast and has an interchange with SR 7 (Santa Fe Pike). Then, they intersect US 31 and US 412 Bus (Nashville Highway). Here, US 43 ends, US 412 continues to the east-southeast on Bear Creek Pike, and SR 6 turns left onto US 31 north.

PA 52 passes through suburban and rural areas along its route. PA 52 was first designated by 1928, continuing northeast from West Chester to New Hope along a concurrency with US 122 (later US 202). This concurrency was removed by 1930 and the northern terminus of PA 52 was cut back to its current location in West Chester. In 2011, a portion of PA 52 north of US 1 was realigned.

NC 461 was established in 1964 as a new primary routing from NC 561 in Saint John to US 13 south of Winton. In 1999, NC 461 was extended east, with a short concurrency with US 13 it splits near Winton, where it follows along Old Highway 13 to NC 45, then in concurrency until Farmers Chemical Road, where it continues as a new primary spur to the steel plant.

In downtown Wrens, they intersect SR 80 (Broad Street), where SR 88 departs the concurrency to the east-northeast. They curve to the northeast and intersect the eastern terminus of SR 47\. Here, US 221 departs the concurrency, with it and SR 47 traveling to the north-northwest. After leaving Wrens, US 1, SR 4, SR 540, and the FLF cross over Reedy Creek on the Floyd L. Norton Memorial Bridge.

SR 24 was designated on the Louisville–Augusta segment, via Wrens. By October 1926, US 1 was designated on the current path. The route of SR 15 between Alma and Hazlehurst, including its concurrency with US 1, was shifted to the east-northeast. SR 32 was designated on the Alma–Baxley segment, with a concurrency with US 1/SR 15 from Alma north to a point southwest of Baxley.

As of today, most organizations use a database management system to support OLTP. OLTP is carried in a client-server system. Online transaction process concerns about concurrency and atomicity. Concurrency controls guarantee that two users accessing the same data in the database system will not be able to change that data or the user has to wait until the other user has finished processing, before changing that piece of data.

KY 63 starts at the Tennessee state line at the northern terminus of Tennessee State Route 56. Just north of that point is Gamaliel, where it intersects Bugtussle Road (KY 87 section 2), and begins its concurrency with KY 100. The two routes have intersections with KY 1860, and KY 1366 during the concurrency from Gamaliel to Tompkinsville. The two routes split at their junction with KY 163 in Tompkinsville.

PA 770 begins in Lafayette Township at an intersection with PA 59. The route goes east to the village of Custer City, where it has a short concurrency with US 219. After the concurrency with US 219, the route continues southeast to its terminus at PA 646 in the village of Aiken. The route goes by 3 names at various points—Warren Road, Buffalo–Pittsburgh Highway, and Minard Run Road.

In Bergen County, CR 501 leaves its concurrency with Route 63 in Palisades Park, using Central Boulevard to connect to the US 1/9/46 concurrency and Route 93. It is then concurrent with Route 93 until it reaches that route's northern terminus at Route 4 in Englewood. CR 501 continues north from this junction through Rockleigh, crossing the New York State Line and becoming New York State Route 340.

The concurrency with SR 121 is short-lived though, as it branches away to the northeast. The US 27-41 concurrency is one of the few segments that are only two lanes wide, and it begins to lean to the northwest until briefly shifting straight north before approaching Archer, where it intersects CR 346, then a former Florida Railway and Navigation Company right-of-way, and finally State Road 24.

After a brief concurrency with PH 4, the highways split in Daxi. Highway 3 continues southwest to Longtan before entering Hsinchu County. In Hsinchu the highway serves as a scenic alternate to Freeway 3, passing through the rural parts of Guanxi, Hengshan, Zhudong, Beipu, Emei, and continues to Miaoli County. In Miaoli the highway had a brief concurrency with County Route 124 in Sanwan before highway 3 splits and continues south.

North of Hertford, it then shares a concurrency with US 17 Bus. before returning on its routing towards Winfall; its old alignment was replaced by US 17 Bus. In June 2016, NC 37 was extended south from St. Johns, in a concurrency with NC 32 and NC 94, into Washington County near Beasley; it splits onto new primary routing to its southern terminus at US 64's exit 548.

The concurrency end at an intersection with SR 18, when SR 13 heads east concurrent with SR 18 and SR 19 heads west concurrent with SR 18\. The concurrency with SR 18 passes through Converse, before SR 19 turns north and SR 18 still heading west. The highway heads towards Peru, passing through rural farmland. The highway enters Peru from the southeast, having an intersection with SR 124\.

The Hewitt, Bishop and Steiger approach concerns sequential processing and inter-process communication in digital, serial, kinematic computers. It is a parallel or pseudo-concurrent theory as is the theory of concurrency. See Concurrency. In Pask's true field concurrent theory kinetic processes can interrupt (or, indeed, interact with) each other, simply reproducing or producing a new resultant force within a coherence (of concepts) but without buffering delays or priority.

In the main part of town is an intersection with SR 32\. On the northern edge of town is an intersection with SR 206 Conn. (North Connector Road). US 441/SR 31 curve to the northwest and enter Broxton, where SR 268 briefly joins the concurrency. After they leave town, they continue to the northwest and have a short concurrency with SR 107, a few miles south of Jacksonville.

Hampton at the western terminus of SR 20 In the seat of Lamar County, Barnesville, US 41 briefly turns to the southwest to meet US 341 at its northern terminus. Here SR 7 joins US 41 again. Proceeding northwest around Barnesville the concurrency is joined by SR 36\. Now turning to the north on the west side of Barnesville, SR 18 leaves the concurrency heading west towards Zebulon.

K-3 was designated in 1927. At that time, the route was almost completely gravel; only the concurrency with US-54 was paved. By 1950, the portion of K-3 in Crawford County had been paved. The portion of the route from the Crawford-Bourbon county line to the west end of the concurrency with K-39 was paved in 1953, and the remainder of the road was paved by 1958.

The byway begins Cocke County at the Tennessee–North Carolina state line along US 25 in Cherokee National Forest. Northbound, the byway crosses the French Broad River twice before reaching the unincorporated community of Del Rio. Departing Del Rio, the byway crosses the Pigeon River and enters the city of Newport. The byway ends its unsigned concurrency (road) with US 25 and begins its concurrency with US 25E/SR 32\.

US 62 leaves US 82/SH 114 in Ralls before beginning a concurrency with State Highway 207. The highway's concurrency with SH 207 ends in Floydada, with US 62 beginning an overlap with U.S. Route 70. US 62 has a lengthy overlap with US 70 that lasts from Floydada to Paducah. In Paducah, US 62 begins an overlap with U.S. Route 83, with the two highways running through Childress.

The second section of SR 5 begins near the historic Legion Field stadium in Birmingham, where US 11 and SR 5 intersect with US 78. At that point, the concurrency of US 11 and SR 5 ends, and the -long concurrency of US 78 and SR 5 begins. US 78 and SR 5 formerly traveled concurrently from Birmingham to Jasper, passing through the Birmingham suburbs of Forestdale, Adamsville, and Graysville.

At this point, US 17 joins the concurrency. A short distance later is an incomplete interchange with Tremont Road. At Ogeechee Road, US 17/SR 25 depart the concurrency to the southwest, while US 80/SR 26 depart to the northeast. I-516/SR 21 continue to the south- southwest and have an interchange with the northern terminus of Veterans Parkway, just before curving to the east-southeast.

PA 66 then joins the concurrency for two miles (3 km) to an exit with U.S. Route 422 Business southeast of downtown Kittanning. Here, US 422 leaves the freeway and heads east toward Indiana while PA 28 and PA 66 remain concurrent as they progress northward. The freeway ends with a concurrency with Pennsylvania Route 66. In Rayburn Township, PA 28/PA 66 intersects the western terminus of Pennsylvania Route 85.

The north section, which is in concurrency with G30 Lianyungang–Khorgas Expressway, was finished in 1995 as a section of the Kaifeng-Luoyang Expressway, which is one of the earliest expressways in Henan. The east section is in concurrency with G4 Beijing–Hong Kong–Macau Expressway, and was finished in 2004. The south and west section, also known as Zhengzhou Southwest Ring Expressway, was finished in August 2005.

US 33 enters Indiana from Ohio heading northwest towards Decatur, as a rural two-lane highway, passing through farmland with a few houses. Along the way passing through a short concurrency with State Road 101 (SR 101), in Pleasant Mills. The highway enters Decatur by curving due west. The road begins a concurrency with US 27, heading due north as a four-lane highway with a center turn lane.

If the check reveals conflicting modifications, the committing transaction rolls back and can be restarted. Optimistic concurrency control was first proposed by H.T. Kung and John T. Robinson. OCC is generally used in environments with low data contention. When conflicts are rare, transactions can complete without the expense of managing locks and without having transactions wait for other transactions' locks to clear, leading to higher throughput than other concurrency control methods.

In the center of Cheshire, the concurrency becomes a 0.15 mile triplex with Route 10. After the Route 70 concurrency ends, Route 68 becomes a 4 lane road as it enters Wallingford. The road narrows to 2 lanes as it passes through Yalesville where it intersects Route 150. After passing under the Wilbur Cross Parkway (Route 15) without an interchange, it meets US 5 at a grade separated interchange.

It reused many ideas and classes from Doug Lea's Collections package, which was deprecated as a result. Sun Microsystems chose not to use the ideas of JGL, because they wanted a compact framework, and consistency with C++ was not one of their goals. Doug Lea later developed a concurrency package, comprising new Collection-related classes. An updated version of these concurrency utilities was included in JDK 5.0 as of JSR 166.

Highway 150 begins at Highway 181 north of Gosnell and the Arkansas International Airport. The highway has a spur route that serves as a shortcut to travelers looking for US 61 southbound and later intersects and begins a concurrency near Yarbro. After the concurrency ends, Highway 150 intersects Interstate 55 at exit 71. East of this junction the route meets Highway 321 before terminating at Highway 137 at Huffman.

Fields and forests surround this thinly populated stretch of highway. At the intersection with Blue Harbor Road, VT 74 turns to the east and heads toward downtown Shoreham. Within central Shoreham, VT 74 is known as Main Street and has a short concurrency with VT 22A. As VT 74 leaves the densely populated portion of Shoreham, the concurrency ends and VT 74 takes an eastward turn toward Cornwall.

Included on the initial discussion report was the I-96/I-275 concurrency with a request for comments by November 5 of that year. When the unit released its final recommendations on March 17, 1983, no changes were proposed regarding the I-96/I-275 concurrency. Other recommendations, such as removing US 2 and US 10 from overlaps with I-75 were implemented in later in 1983 and in 1985, respectively.

The concurrency with US 54 lasts until Tularosa, and the highway remains divided until US 70 and US 54 diverge. After splitting off to the northeast, US 70 begins an ascent into the Sacramento Mountains and enters the Lincoln National Forest. The road then runs across the Mescalero Apache Indian Reservation and near the resort town of Ruidoso. In Hondo, it begins another concurrency, this time with US 380\.

In Dawson, there is an intersection with SR 45, which begins a short concurrency with SR 520\. A short distance later is an intersection with SR 32, followed by US 82/SR 45/SR 50, where the concurrency with SR 45 ends and the one with US 82 begins. Just before leaving town, US 82/SR 520 intersect SR 55\. The two highways head southeast until they reach Albany.

Having concurrency with shared memory gave rise to the problem of concurrency control. Originally, this problem was conceived as being one of mutual exclusion on a single computer. Edsger Dijkstra developed semaphores and later, between 1971 and 1973, Tony Hoare and Per Brinch Hansen developed monitors to solve the mutual exclusion problem. However, neither of these solutions provided a programming language construct that encapsulated access to shared resources.

To the northeast, they pass through East Point, where they have an interchange with SR 154/SR 166 (Arthur B. Langford Jr. Parkway), just before they enter Atlanta and pass Fort McPherson. At this interchange, SR 154 joins the concurrency. They pass through the Oakland City neighborhood before SR 139 departs to the west on Ralph David Abernathy Boulevard. After leaving the concurrency, it passes through the West End neighborhood.

Route 13 begins at the Arkansas state line in Blue Eye. After leaving the town, it travels through the rugged countryside of the southwest Missouri Ozarks, part of the Mark Twain National Forest. Route 13 forms a concurrency with Route 86 before bridging Table Rock Lake south of the town of Branson West. In Branson West, it leaves the national forest and forms a concurrency with Route 76 and Route 265\.

The highway collects Interstate 39, southeast of Tomah (near Portage). This concurrency of about is one of only two three-route concurrency of the Interstate Highway System existence, the other being in Milwaukee. I-39 continues along I-90 for the remaining in Wisconsin. I-94 breaks away eastward toward Milwaukee at what is commonly known as the Badger Interchange, where the three Interstates meet with WIS 30.

SR 141 continues generally southward until reaching Center Hill Dam. At this point, SR 141 starts a concurrency with SR 96. This concurrency turns northeastward and goes across the dam, then SR 96 splits off at a four-way intersection with Edgar Evins State Park Road and Medley-Amonette Road (SR 96). SR 141 continues east as Wolf Creek Road through hilly terrain before crossing into Putnam County.

In Bethel Township, PA 66 meets the northern terminus of PA 66 Alternate. In Ford City, PA 66 becomes Main Street and intersects the northern terminus of Pennsylvania Route 128 at an "Y" intersection. Southeast of Kittanning, PA 66 begins a concurrency with U.S. Route 422 and Pennsylvania Route 28 at an interchange. At the next exit US 422 leaves the concurrency and PA 28/PA 66 continue north at-grade.

About nine miles east of the concurrency, the route enters the city of Grafton. In central Grafton, ND 17 forms a very short concurrency with US 81 which remains inside the city limits. Ten miles east of Grafton, the highway shares an interchange with Interstate 29. The highway then heads east for a mile and a half more before crossing the Red River of the North and entering Marshall County, Minnesota.

NC 132 ends at a roundabout with NC 133 just south of Castle Hayne. NC 133 and US 117 continue together to the north on a separate concurrency.

The concurrency has an interchange with SR 53 (Experiment Station Road). To the north-northeast, they intersect US 129 Bus./US 441 Bus./SR 15/SR 24 Bus.

It joins the concurrency as an unsigned highway. Almost immediately, first SR 69 and then CR 44 split off. At this point, US 43 resumes a northward direction.

US 33 was rerouted onto its modern concurrency with SR 13, between 1970 and 1971. The southern end was moved to Fortville from Greenfield between 1976 and 1977.

Pennsylvania Route 951 began at the concurrency of U.S. 219/U.S.322 in Luthersburg/Clearfield County and ran for 10 miles to U.S. 322 in Prescottville/Jefferson County.

In Crescent City US 24 intersects IL 49\. In Watseka, it overlaps IL 1 through the town; the final concurrency, with US 52 in Sheldon carries into Indiana.

The ConGolog language provides concurrency and interrupts. Other dialects like IndiGolog and Readylog were created for real time applications in which sensor readings are updated on the fly.

Other CO articles followed. (Bernstein and Newcomer 2009) note CO as one of the four major concurrency control methods, and CO's ability to provide interoperability among other methods.

The Java collections framework was designed and developed primarily by Joshua Bloch, and was introduced in JDK 1.2. The original concurrency classes came from Doug Lea's collection package.

The route begins at US Route 49 in Brinkley, just north of Interstate 40. The route heads north for about 8.4 miles (13.5 km) before intersecting Highway 38 in Cotton Plant. Both highways share a concurrency heading east for about 1.7 miles (2.7 km) before heading north again. From there, the route continues to head north, intersecting Highway 306 north of Cotton Plant, and Highway 260 sharing a concurrency south of Patterson. The route will come to another three-way intersection with US Route 64 in Patterson, and will share a concurrency with US Route 64 for about 2 miles (3 km) until turning north in McCrory at the intersection of US Route 64 and Highway 145.

SR 623 just east of Emporia, Virginia US 58 enters Virginia and travels east to Jonesville, where Alternate US 58 branches off and travels to the north. East of Jonesville, US 58 intersects US 421, and the two routes stay concurrent through Duffield (where the concurrency also picks up U.S. 23), Gate City, Weber City (where the US 23 concurrency ends), and Bristol, where US 58 begins a concurrency with Interstate 81. The two routes stay concurrent until I-81 exit 19 in Abingdon, where US 58 resumes its eastward journey close to the Virginia–North Carolina state line. The route is signed as the J.E.B. Stuart Highway and the A. L. Philpott Memorial Highway.

About later, or west of the borough of Emlenton, the route is joined by PA 38; this route, just south of this intersection, meets I-80 (exit 42). The concurrency meets the northern terminus of PA 268 about later in the borough, and turns north to cross the Allegheny River. The concurrency turns east at the center of the town, then crosses into Clarion County later, winding northward, eastward, and finally east-northeastward, crossing back into Venango County again later. The concurrency meets the northern terminus of PA 478 later; just south of this intersection, PA 478 has a partial interchange with I-80 (exit 45) for traffic exiting or entering eastbound.

State Route 568 (SR 568) is an east-west state highway in the northwestern portion of the U.S. state of Ohio. The western terminus of this highway is at a signalized intersection in downtown Findlay where it meets State Route 12 and State Route 37. The eastern terminus of State Route 568 is in downtown Carey at a signalized intersection that serves as all of the northern split of the U.S. Route 23/State Route 103 concurrency, the western split of the State Route 103/State Route 199 concurrency and the southern split of the U.S. Route 23/State Route 199 concurrency. State Route 568 was created in the middle of the 1960s.

Then the road heads towards Ligonier, passing through a four-stop intersection with SR 9 in Merriam. Then in Wolf Lake the road has an intersection with SR 109 at the main intersection in town. Then south of Ligonier the road passes through Kimmell and the route begins a concurrency with SR 5\. The concurrency with SR 5 ends at the intersection with US 6 in Ligonier. Both US 6 and US 33 head west away from Ligonier as a two-lane highway passing through farmland with some houses, for . Then US 33 turns north, now concurrent with SR 13, the concurrency with SR 13 last for , with SR 13 turning east and US 33 turning northwest.

The concurrency remains as Lee Highway through Calhoun and intersects and has a short concurrency with SR 163 (Lamonville Road/Bowater Road) and then continues to the northeast. US 11 Business splits away in Riceville with SR 39 (Riceville Road) and goes northeast through downtown Athens as US 11/SR 2 continues northeast, briefly running a concurrency with SR 39 in Riceville before it heads into downtown concurrent with US 11 BUS, and around the northwest side of downtown Athens as Congress Parkway. It then intersects SR 30 (Decatur Pike) before leaving Athens. Just north of Athens, US 11 BUS/SR 305 (Ingleside Avenue) intersect US 11/SR 2 where US 11 BUS terminates.

As such CO provides a low overhead, general solution for global serializability (and distributed serializability), instrumental for global concurrency control (and distributed concurrency control) of multi database systems and other transactional objects, possibly highly distributed (e.g., within cloud computing, grid computing, and networks of smartphones). An atomic commitment protocol (ACP; of any type) is a fundamental part of the solution, utilized to break global cycles in the conflict (precedence, serializability) graph. CO is the most general property (a necessary condition) that guarantees global serializability, if the database systems involved do not share concurrency control information beyond atomic commitment protocol (unmodified) messages, and have no knowledge whether transactions are global or local (the database systems are autonomous).

At College Street, SR 23 begins a concurrency for a few blocks. At Lewis Street is an intersection with SR 121\. Here, SR 23 splits off to the south.

It offers type 3 flow granularity with concurrency, but with more flow scheduling control than Multipath TCP. It also fully supports mobility in a fashion similar to Multipath TCP.

U.S. Route 601 Truck is an alternate route for trucks to avoid downtown Camden. The route is in complete concurrency with US 521 Truck on Springdale Drive/Boykin Road.

U.S. Route 601 Business is a business loop that follows the original mainline of US 601 along Hampton Street. The route is in complete concurrency with US 521 Business.

U.S. Route 11 Truck (US 11 Truck), which shares a complete concurrency with US 19 Truck, provides a bypass route for truckers avoiding the residential area of Euclid Avenue.

The five-highway concurrency travels to the west-southwest. Immediately, they curve to the west-northwest. An intersection with the southern terminus of Wilkerson Street leads to Memorial Stadium.

The five- highway concurrency travels to the west-southwest. Immediately, they curve to the west-northwest. An intersection with the southern terminus of Wilkerson Street leads to Memorial Stadium.

F. Lynes Parkway). Here, US 17 begins a concurrency with I-16. It crosses over the Springfield Canal just before a partial interchange with SR 204 (West 37th Street).

Io uses actors for concurrency. Remarkable features of Io are its minimal size and openness to using external code resources. Io is executed by a small, portable virtual machine.

After the concurrency with SR 4, the road keeps going south to Turner where the road ends at SR 219 just west of its crossing of the Androscoggin River.

It continues south in a concurrency with G15 Shenyang-Haikou Expressway and G1504 Ningbo Ring Expressway for a short section in Yinzhou District before returning to its southern terminus.

In the even smaller incorporated town of Eros, LA 34 has a brief concurrency with LA 148 and also intersects LA 144, which heads north toward Calhoun and Choudrant.

In Stilson, they intersect the northern terminus of SR 119 Conn. They travel to the southeast and have a brief concurrency with SR 119 just before entering Bryan County.

Just after leaving the city limits, it passes Fort Pond Elementary School. Then, the highway travels through Macedon. It has a concurrency with SC 6\. They split in Edmund.

At Km Km 58.4, Highway 705 begins a short northern bearing concurrency with Highway 36 through the town of Willow Bunch. At Km 59.2, the concurrency ends at Km 59.2 when Highway 705 turns to the east once more. At Km 75.0, Highway 705 turns south until Km 82.2 when it enters Harptree at the Highway 607 junction. The southerly direction is necessary to skirt around the southern shores of Willow Bunch Lake.

SR 174 begins at an intersection with SR 106 northeast of Ila, in Madison County. It heads northeast to an intersection with US 29/SR 8, where the three highways begin a concurrency to the northeast. Just before the concurrency ends they cross the Hudson River and enter Franklin County. After entering the county, SR 174 splits off to the northwest and meets its northern terminus, an intersection with SR 51 west of Franklin Springs.

The Heterogeneity and Autonomy requirements pose special challenges concerning concurrency control in an FDBS, which is crucial for the correct execution of its concurrent transactions (see also Global concurrency control). Achieving global serializability, the major correctness criterion, under these requirements has been characterized as very difficult and unsolved. Commitment ordering, introduced in 1991, has provided a general solution for this issue (See Global serializability; See Commitment ordering also for the architectural aspects of the solution).

Here, the "River Road" name continues to the northwest. SR 230 continues to the northeast until it reaches Byromville, where it has a brief concurrency with SR 90\. It continues heading northeast, before heading east to its intersection with SR 329 northeast of the unincorporated community of Snow Spring, which is west of Unadilla. In Unadilla is an interchange with Interstate 75 (I-75) and a very brief concurrency with US 41/SR 7\.

In computer science, unbounded nondeterminism or unbounded indeterminacy is a property of concurrency by which the amount of delay in servicing a request can become unbounded as a result of arbitration of contention for shared resources while still guaranteeing that the request will eventually be serviced. Unbounded nondeterminism became an important issue in the development of the denotational semantics of concurrency, and later became part of research into the theoretical concept of hypercomputation.

It then heads northward, and begins to curve northwest over the Cache la Poudre River and into Windsor. It intersects SH 392 and abruptly turns west, beginning a concurrency at Main Street; about a mile later SH 257 abruptly turns back northward at 7th Street, ending the concurrency. It then heads all the way north to SH 14, where it terminates. No towns exist on the route from Windsor to SH 14.

To remove the redundant designations, both SH-34 and SH-44 were truncated to their current southern terminus on January 5, 1987. SH-6 was realigned twice in 2004 to allow SH-6 a straighter route in situations where it was concurrent with another highway. The first such section removed a portion of the US-283 concurrency between Blair and Granite; the second realignment took place on the SH-55 concurrency north of Retrop.

Between Newark and Jersey City, US 1/9 runs along the Pulaski Skyway. Trucks are banned from this section of road and must use US 1/9 Truck. The concurrency between US 1 and US 9 is commonly referred to as "1 and 9". Some signage for the concurrency, as well as the truck route, combines the two roads into one shield, separated by a hyphen (1-9) or an ampersand (1&9).

At this intersection, NY 7 forks onto a concurrency with NY 10 south, while NY 145 turns north onto North Grand, running concurrent with NY 10 north. This concurrency lasts three blocks, before NY 10 turns west on Elm Street. NY 145 continues north out of the village of Cobleskill. The route passes west of Cobleskill Rural Cemetery before crossing the town line at Edgewood Drive, back into the town of Cobleskill.

Now named Sunset Avenue, the route passes through developed parts of Springdale, including many restaurants, hotels, and businesses before turning south, forming a concurrency with US 71B. The concurrency ends and US 412 heads east past the Springdale Municipal Airport and Highway 265 out of town. Again becoming four-lane divided, the route winds east to Hindsville. The route nears Hindsville, including an intersection with a former alignment now designated US 412B.

AASHTO policy allows dual numbering to provide continuity between major control points. This is referred to as a concurrency or overlap. For example, I‑75 and I‑85 share the same roadway in Atlanta; this section, called the Downtown Connector, is labeled both I‑75 and I‑85. Concurrencies between Interstate and U.S. Route numbers are also allowed in accordance with AASHTO policy, as long as the length of the concurrency is reasonable.

CR 4011 enters Tomoka State Park just before it crosses over a bridge at the mouth of the Tomoka River. Along the western edge of Bulow Creek State Park, CR 4011 forms a concurrency with CR 2002 then turns west, while the Ormond Trail turns east onto CR 2002\. The northern terminus is at I-95, ending the concurrency of CR 2002/CR 4011\. The southern terminus is SR 430 in Daytona Beach.

East of Bellville SR 97 curves towards the east, passing through farmland and woodland. The route makes a sharp turn towards the south-southeast crossing the Clear Fork Mohican River for the final time. After crossing the river, SR 97 enters Butler and passes through residential properties, before beginning a concurrency with SR 95\. The concurrency curves towards the east, before ending, with SR 95 heading due north and SR 97 continuing towards the east.

The concurrency travels through the Brookview Heights neighborhood, southwest of Carey Park and Williams Elementary School. A short distance later, they intersect SR 280 (locally known as Hamilton E. Holmes Drive to the south and James Jackson Parkway NW to the north). After curving to an eastern routing, the three highways pass Center Hill Park. At an intersection with the southern terminus of Hollywood Road NW, the concurrency curves to the southeast.

They curve to the north-northwest, before curving to the north and meeting US 84/SR 38, which join the concurrency. Immediately afterward, the five highways travel to the north-northeast and leave the city limits. The concurrency travels through rural parts of the county, before traveling through Doctortown, and curving to the northeast and crossing over the Altamaha River into Long County on the Dr. J. Alvin Leaphart Sr. Memorial Bridge.

After continuing to the north-northwest, US 25/SR 67 pass just to the northeast of Paynes Chapel Cemetery and Clifton Cemetery, before they curve to the north-northeast. Then, they intersect SR 121, which joins the concurrency. Approximately later, immediately after traveling through Emmalane, they intersect SR 23, which also joins the concurrency. At Union Camp Logging Road, the four highways curve to the northeast and cross over the Ogeechee River.

SC 9/SC 57 turn right onto US 301/US 501 (North 2nd Avenue) slightly to the northeast. At Julia Lane, they split off from the concurrency to the northwest. They have an interchange with Interstate 95 (I-95) just before leaving the city. At the northern part of Little Rock, SC 57 departs the concurrency curving to the northeast until it meets its northern terminus, the North Carolina state line north of Little Rock.

This interchange is the east end of the US 421 concurrency with I-40 and is also the planned western terminus of Interstate 840. From there Interstate 40 heads through southwestern Greensboro. Interstate 40 passes Wendover Place and Four Seasons Town Centre before having another large interchange with US 220. 1 mile after the interchange with US 220 US 29/US 70 all merge into I-40/US 220 for one large concurrency.

After crossing the Dyer River, the road briefly jogs northwest and then comes to a wye intersection with SR 126\. SR 126 and SR 215 share a short concurrency until SR 215 breaks off the concurrency at a second wye intersection. Now heading north on North Clary Road, the road winds its way through wooded area. It climbs to the top of Brooks Turner Hill and shortly afterwards, comes to an end at SR 32.

After a very brief unsigned concurrency with CR 40 (Campground Road/Sherman Road), it curves to the north- northwest and has another unsigned concurrency with CR 12 (Max Vintson Road/Etteca Road). After curving to the north-northeast, it intersects CR 55 (Doughty Road/Shiver De Freeze Road). US 43 travels to the north and enters Fayette County. ;Fayette County US 43 winds to the north-northeast and intersects the eastern terminus of CR 26\.

SR 83 begins at an intersection with US 341/SR 7 (Peach Blossom Trail) northeast of Culloden, in Monroe County. It heads northeast, briefly paralleling the Monroe–Lamar county line, to Forsyth. Once in Forsyth, the route forms a concurrency with US 41/SR 18, heading to downtown. Once in downtown Forsyth, the route intersects US 41/SR 18/SR 42\. Here, SR 42/SR 83 begin a brief concurrency to the north.

The route begins at an intersection with KY 555 south of Willisburg and heads northeast through the city. It continues northeast into Anderson County and intersects the Martha Layne Collins Blue Grass Parkway. Just south of Beaver Lake KY 53 turns toward the northwest and forms a concurrency with US 62. Further north in Glensboro, it forms a concurrency with KY 44 and continues northwest, briefly passing through Spencer County before entering Shelby County.

Along State Road 101 at its intersection with U.S. Route 224 The fourth and final portion is long and has its southern terminus at SR 124 in southeastern Adams County and heads north passing through farmland. The road enters Pleasant Mills and has a short concurrency with US 33\. North of Pleasant Mills, the road crosses over the St. Marys River. After the river, the road enters Rivare and starts a concurrency with US 224\.

MD 4 has several names over its course. The highway is named St. Andrew's Church Road and Patuxent Beach Road west and east of MD 235, respectively, in St. Mary's County. The highway follows Solomons Island Road throughout its concurrency with MD 2, which at is the longest state-numbered-highway concurrency in Maryland. MD 4 is known as Southern Maryland Boulevard from MD 2 in Sunderland to MD 258 in Bristol.

The highway enters Bremen at Industrial Drive, passing through commercial properties. Between Hope Boulevard and Birkey Street, Plymouth Street curves due east and enters downtown Bremen. In downtown Bremen the street has a traffic light at the western end of the SR 331 concurrency. The concurrency heads east leaving downtown Bremen and passing through residential properties, on the east side of Bremen. SR 106 leaves SR 331 heading north, concurrent with Douglas Road.

Lake Mary Boulevard, Airport Boulevard and State Road 417 cross US 92 in southern Sanford, and it meets the west end of County Road 427A. At 25th Street, southwest of downtown Sanford, State Road 46 comes in from the east and turns north for a concurrency near downtown; County Road 46A heads west on 25th Street. 13th Street marks the west end of County Road 415, and at 1st Street the triple concurrency turns west.

State Route 380 (SR 380) is a north-south state highway in the southwestern quadrant of the U.S. state of Ohio. The southern terminus of SR 380 is at its junction with the concurrency of U.S. Route 22 (US 22) and SR 3 nearly northeast of Clarksville. Its northern terminus is in downtown Xenia, following a brief concurrency with US 68, at the signalized intersection where the U.S. route meets US 42\.

PostgreSQL manages concurrency through multiversion concurrency control (MVCC), which gives each transaction a "snapshot" of the database, allowing changes to be made without affecting other transactions. This largely eliminates the need for read locks, and ensures the database maintains ACID principles. PostgreSQL offers three levels of transaction isolation: Read Committed, Repeatable Read and Serializable. Because PostgreSQL is immune to dirty reads, requesting a Read Uncommitted transaction isolation level provides read committed instead.

County Route 583 (CR 583) is a county highway in the U.S. state of New Jersey. Its northern end is at an intersection with Route 27 in Princeton; its southern end is in a concurrency with U.S. Route 1 Business and U.S. Route 206 at an intersection with County Route 653 in Trenton. The entire route is municipally-maintained except for its concurrency with US 206 where it is maintained by the Mercer County D.O.T.

Here, it becomes Main Street and intersects US 20A, which forms a concurrency with NY 15A along the length of Main Street. The concurrency continues through Hemlock and into rural Livonia, where the overlap ends as US 20A turns west towards Buffalo. NY 15A, meanwhile, heads northward into the town of Lima as Plank Road. It continues across rural terrain for another to the village of Lima, where it becomes Lake Avenue.

State Route 16 (SR 16) is a state highway in the U.S. state of Tennessee. Its southern terminus is at the Alabama State Line, where it continues as State Route 79 (SR 79) in Alabama. From there, it continues to Winchester, where it becomes unsigned in a concurrency with U.S. Route 41A (US 41A). This concurrency lasts until its northern terminus in Williamson County, at a junction with U.S. Route 31A (US 31A).

SR 342 begins inside Panther Creek State Park at the intersection of Panther Creek Park Road and Panther Creek Road. The route then heads southeast to junction with US 11E and the two routes begin a short concurrency to and intersection with SR 160 where SR 342 turns south along SR 160. The two routes begin a short concurrency. Then SR 342 turns southeast and meets its eastern terminus, an intersection with SR 66.

SH-3 and SH-33 concurrency in eastern Blaine County. At mile 94.2, SH-33 reaches an intersection involving five state highways. If the driver continues straight at this intersection, he will be on SH-58, which leads to Canton Lake. A left turn will follow the three-route concurrency of SH-3, US-270, and US-281, which is the so-called Governor George Nigh Northwest Passage to Woodward and the panhandle.

Concurrency::parallel_for (0, width, [=](int x) { //Something parallelizable }); This still requires the developer to know that the loop is parallelizable, but all the other work is done by the library. MSDN describes the Parallel Patterns Library as an "imperative programming model that promotes scalability and ease-of-use for developing concurrent applications." It uses the Concurrency Runtime for scheduling and resource management and provides generic, type-safe algorithms and containers for use in parallel applications.

Concurrency control mechanisms firstly need to operate correctly, i.e., to maintain each transaction's integrity rules (as related to concurrency; application-specific integrity rule are out of the scope here) while transactions are running concurrently, and thus the integrity of the entire transactional system. Correctness needs to be achieved with as good performance as possible. In addition, increasingly a need exists to operate effectively while transactions are distributed over processes, computers, and computer networks.

This model can be applied to an existing instruction set architecture incrementally by providing just five new instructions to implement concurrency controls. A set of microthreads is a static partition of a basic block into concurrently executing fragments, which execute on a single processor and share a microcontext. An iterator over a set provides a dynamic and parametric family of microthreads. Iterators capture loop concurrency and can be scheduled to different processors.

The route begins at SH 1 in Tokoroa and travels west along Maraetai Road, leaving Tokoroa where the road angles in a more southerly direction through the Kinleith Forest. It eventually meets at a three way junction. From here both SH 32 and SH 30 share a short concurrency of , crossing the Waikato River over the Whakamaru Dam. Shortly after reaching the locality of Whakamaru, SH 32 leaves the concurrency and continues south.

New Cleveland. SR 109 heads north concurrent with SR 15 and SR 65, in downtown Ottawa. The route heads through the north side of downtown Ottawa as a two-lane highway with a center turn lane, passing through a mix of residential and commercial properties. The concurrency curves northeast and has a traffic signal at the northern end of the SR 15 concurrency, SR 15 heads northwest and the other two routes continues northeast.

The US 522 concurrency continues until Lewistown. US 22 bypasses the downtown area of Lewistown as a four-lane limited access highway and becomes concurrent with US 322, continuing as a four-lane limited access highway along the Juniata and Susquehanna rivers until Harrisburg. In Harrisburg (with the US 322 concurrency ending at I-81), it continues as N Cameron Street, Arsenal Blvd., Herr St., Walnut St., Jonestown Rd., and Allentown Blvd.

PA 66 approaching its end at US 6 in Kane After crossing the Redbank Creek, PA 28/PA 66 have entered Clarion County. In New Bethlehem, The concurrency between PA 28 and PA 66 ends when PA 66 leaves PA 28. North of PA 28, PA 66 becomes Wood Street and intersects the eastern terminus of Pennsylvania Route 861. In Clarion Township, PA 66 begins a concurrency with Interstate 80 at exit 64.

The routes follow the banks of the Merrimack until Route 110 turns northward along Emerson Street. It crosses Route 97 before having a brief concurrency with Route 125, turning northward.

By August 2013, the peak player concurrency had reached 460,000. By August 2015, over 5 million copies had been sold, at which point the base game became free-to- play.

It initially overlapped NY 174 from Forward Road to Camillus; however, this concurrency was eliminated in the 1960s. NY 321 was rerouted to follow Bennetts Corners Road in the 1980s.

SR 107 has an intersection with SR 268 in Snipesville before reaching its eastern terminus with US 221 north of Denton. West end of SR 112 concurrency in Turner County.

Scala Joins is a library to use Join-Pattern with Scala in the context of extensible pattern matching in order to integrate joins into an existing actor-based concurrency framework.

The highways begin a concurrency to the south. Almost immediately, they leave Buffalo. They cross over the South Fork Grand River. When they split, SD 20 resumes its eastward direction.

Joyce is based on a small subset of Pascal, extended with features inspired from CSP for concurrency. The following sections describe some of the more novel features that were introduced.

This means that if two connections are made to the same database, a `ROLLBACK` made in one connection will not affect any other connections. This is vital for proper concurrency.

US 12 was transferred to the City of Niles. In doing so, the Bus. US 12 designation was decommissioned in the city, removing that designation from the M-51 concurrency.

US 441/SR 15 leaves the concurrency at Exit 12, and US 129 leaves the Athens Perimeter at Exit 14, joining SR 15 Alt. which actually began at Exit 6.

Just north of Thomson is an interchange with I-20. In Washington, SR 17 intersects US 378, and departs the concurrency with US 78/SR 10, before leaving the town.

Shortly after this transition, Route 120 leaves the concurrency, heading north to its northern terminus at an intersection with Aomori Prefecture Route 16 (Shinmachi Street) just east of Aomori Station.

Coroutines are a fine-grained concurrency primitive, which may be required to yield explicitly. They may enable specifying another function to take control. Coroutines that explicitly yield allow cooperative multitasking.

The east-west concurrent segment with SR 124 became just SR 124, while the north-south concurrent stretch with SR 124 turned into a concurrency of SR 7 and SR 124.

In Liberty SR 44 has a concurrency with U.S. Route 27. From Liberty SR 44 heads east towards Ohio; at the Ohio state line SR 44 becomes Ohio State Route 725.

The concurrency curves to the north-northeast and curve back to the north- northwest. They then intersect the western terminus of CR 50\. They intersect the southern terminus of CR 54\.

At Broadway, SH-56 joins the concurrency. Finally, at the north end of town, US-62 turns west on Columbia, while SH-56 turns east; SH-27 ends at this intersection.

Highway 913 is about long. Highway 913 also connects with Highway 963. Traveling 41.2 kilometres is a concurrency with Highway 912 for 5 kilometres. Highway 913 is gravel its whole length.

Other concurrency systems (e.g., process calculi) can be modeled in the actor model using a two-phase commit protocol.Frederick Knabe. A Distributed Protocol for Channel-Based Communication with Choice PARLE 1992.

Four segments had a sand clay or top soil surface: from Lula to the southern part of Homer, from the northern part of Homer to the SR 106 intersection south-southwest of Carnesville, from the east end of the SR 145 concurrency south-southeast of Carnesville to Canon, and the northern half of the Hartwell–Reed Creek segment. Between April 1949 and August 1950, the Lula–Homer segment was hard surfaced. By the end of 1951, two segments were hard surfaced: from the SR 106 intersection to the east end of the SR 145 concurrency and nearly the entire Hartwell–Reed Creek segment. In 1953, the segment from the east end of the SR 145 concurrency to Canon was hard surfaced.

Three segments had completed grading, but was not surfaced: from east-northeast of Homer to the SR 59 intersection west-southwest of Carnesville, a portion just east of the east end of the SR 145 concurrency, and the northern part of the Hartwell–Reed Creek segment. Between June 1954 and June 1955, from Homer to just east of the Banks–Franklin county line, the highway was hard surfaced. Between July 1957 and June 1960, two segments were paved: from Lula to the east end of the SR 145 concurrency and from just east of this point to just south of Reed Creek. By the end of 1965, a portion just east of the east end of the SR 145 concurrency was hard surfaced.

"Dining Philosophers", a classic problem involving concurrency and shared resources In computer science, concurrency is the ability of different parts or units of a program, algorithm, or problem to be executed out-of-order or in partial order, without affecting the final outcome. This allows for parallel execution of the concurrent units, which can significantly improve overall speed of the execution in multi-processor and multi-core systems. In more technical terms, concurrency refers to the decomposability property of a program, algorithm, or problem into order-independent or partially-ordered components or units. A number of mathematical models have been developed for general concurrent computation including Petri nets, process calculi, the parallel random-access machine model, the actor model and the Reo Coordination Language.

In Lewis Center, US 23 once again becomes an expressway, and remains as such until Carey, except for a small portion north of Delaware. Between Marion and Carey, all junctions with other routes are exits, except for SR 529 east of Marion and SR 294 east of Harpster. The route becomes concurrent with US 42 along an eastern bypass of Delaware, then bypasses Waldo and Marion to the east. It bypasses Upper Sandusky to the east and north, mostly in concurrency with US 30. The route then departs the expressway at Carey, becoming concurrent with SR 103 while the expressway continues westerly as SR 15. Within Carey, the concurrency with State Route 103 ends, and a concurrency with SR 199 begins.

In Baldwin US 301 crosses railroad tracks that serve the suspended Amtrak Sunset Limited before making a right turn at a concurrency with US 90 for several blocks. This concurrency may become history if the Florida Department of Transportation decides to build the proposed Baldwin Bypass around the western edge of town.US 301 Expansion; Baldwin Bypass (FDOT, Region #2) Immediately after another railroad crossing, both US 90 and 301 narrow down to two lanes at the east end of this concurrency. US 301 remains a two- lane rural highway until it reaches Callahan where it crosses over a railroad bridge and gets the name West First Avenue, although this segment is planned to be widened to four lanes by FDOT.

Running generally north, Route 138 crosses from Rhode Island into Fall River, where it meets the southern terminus of Route 79 at exit 5 of Interstate 195, then begins a concurrency with Route 79 and later, U.S. Route 6. Routes 138 and 6 then travel off of Route 79 and over the Brightman Street Bridge into Somerset, where the concurrency with U.S. Route 6 splits at an intersection with Route 103. Route 138 proceeds through Dighton and into Taunton, intersecting Route 140 and U.S. Route 44 at Taunton Green. In Raynham, the route has an interchange with Interstate 495 at exit 8 before continuing into Easton, where it intersects Route 106 before beginning a brief concurrency with Route 123 near Stonehill College.

US 60 runs in a northeasterly direction across the Texas Panhandle. It enters the state as a four-lane divided highway at Farwell on the Texas-New Mexico border, and heads northeast, intersecting U.S. Route 385 at Hereford. At Canyon, the route begins a concurrency with both U.S. Route 87 and Interstate 27; the three routes are united to Amarillo. At Amarillo, the road crosses Interstate 40 and has a short concurrency with Historic US 66 on Amarillo Boulevard.

Except for three short sections near Enid, Vinita, and Ponca City, US 60 is a two-lane highway its entire length across Oklahoma. It enters the state west of Arnett and travels east to Orienta where it begins a concurrency with U.S. Highway 412. At Enid, it leaves the concurrency with US-412 and begins another with U.S. Highway 64 with which it is united for . Near Tonkawa, US 60 has an interchange with Interstate 35.

In downtown Arlington, the three highways enter Calhoun County and cross a Norfolk Southern Railway track. Then, SR 62 departs to the northeast on Pioneer Road. Two blocks later, SR 45 leaves the concurrency to the northeast on Morgan Road NE. SR 216 heads north to Edison, where it has a brief concurrency with SR 37 (Hartford Street). The highway heads north, curves to the northwest, and then curves back to the north, until it enters Randolph County.

The highway begins at Highway 8 in the southwest corner of Cleveland County near New Edinburg at Marks' Mills State Park and a National Historic Landmark. Highway 97 runs northwest toward Kingsland, beginning a concurrency with Highway 189 just south of the city. Once inside the city limits, Highway 189 turns left at 1st Street, ending the concurrency. Highway 97 continues along 1st Street and 3rd Street eastward to a junction with US 79, where it terminates.

Route 33 starts at an intersection with Rhode Island Route 3 in Coventry. It runs north and crosses the South Branch Pawtuxet River before turning east to form a concurrency with Rhode Island Route 117. Route 33 splits off to the northeast and continues along the bank of the South Branch Pawtuxet River. It forms a concurrency with Rhode Island Route 115, crosses over the river, leaves Route 115, and then continues north over the Pawtuxet River.

When the system was commissioned however, noticeable changes had been made. US 60 had been renumbered to US 66 and US 280 and US 380 became a southern extension of US 89\. This also meant US 89 shared a long concurrency with US 80 between Phoenix and Tucson, as well as a wrong-way concurrency with US 66 between Flagstaff and Ash Fork. In 1931, US 70 became the first U.S. Highway to be decommissioned in Arizona.

The route traverses the Francis Marion National Forest as it oontinues northward to St. Stephen. From there is proceeds to Kingstree and Lake City, before another short concurrency with US 301 from Effingham to Florence. Through downtown Florence, it goes northwest and bypasses Darlington and joining another concurrency with US 401\. At Society Hill, it merges briefly with US 15 before continuing north again solo to Cheraw, where it overlaps briefly with US 1 and SC 9\.

Two decades later, SR 2 east of Cisco was impassable due to rock slides. It wasn't until near the end of the 1980s that SR 2 was re-routed south-southwest along US 411/SR 61 from Cisco to Chatsworth, where it began a concurrency with US 76/SR 52\. US 76/SR 2/SR 52 traveled to the east and southeast into Ellijay, where SR 52 departed the concurrency. US 76/SR 2 turned left onto SR 5\.

Upon crossing into the city of Ise, Routes 42 and 167 meet the eastern terminus of the Ise Futami Toba Line, an limited-access highway signed as a bypass of National Route 42. The northern terminus and ending point of National Route 167 is at an intersection where the concurrency between it and National Route 42 meet National Route 23. National Route 42 continues beyond the ending point of National Route 167 in another concurrency with National Route 23.

U.S. Route 322 also starts a concurrency with US 6 in Public Square that ends 0.5 mi east of the plaza East of Public Square, US 6 has an interchange with Interstate 90. 4.5 miles east of this intersection, US 6 starts another concurrency with US 20 in East Cleveland that lasts for 4.2 miles. After splitting from US 20, US 6 runs concurrent with Ohio State Route 84 for 2.1 miles before entering Lake County.

US 6 crosses into Williams County, Ohio, at the Indiana state line between Butler, Indiana, and Edgerton, Ohio. The highway goes east from the border, passing through the small town of Edgerton, where it has a brief concurrency with Ohio State Route 49. Continuing east through farm country, US 6 passes through Ridgeville Corners, until reaching Napoleon in Henry County, where it intersects US 24, starting a 4.6-mile long concurrency. East of Napoleon, US 6 passes through McClure.

The route then has a concurrency with SR 302 and a concurrency with US 27/SR 29. US 27 and SR 68 go north to Spring City where SR 68 turns back west and US 27 goes north. Just after leaving Spring City, it turns back to north crosses over Waldens Ridge into Cumberland County where the route ends at a Y-intersection with US 127/SR 28 in Cumberland Homesteads near Crossville and Cumberland Mountain State Park.

The westbound interchange ramps are 0.3 eastward on the PA 38/PA 208 concurrency, which continues northeasterly to the county line later. After crossing into Clarion County a second and final time, the PA 38/PA 208 concurrency continues north-northeastward before its northern terminus. PA 208 turns eastward and winds to the borough of Knox, where the route turns south and then east again, intersecting with PA 338 about from the center of the borough.

After a short concurrency, the route drops S.R. 17 and continues west with S.R. 133. Eventually, it turns off of the concurrency and heads north, crossing the Tennessee state line directly beside the Natchez Trace Parkway. The route becomes Tennessee State Route 227, which loops around and acts as the northern terminus to Alabama State Route 101. This route is an important connector between multiple cities in Northwestern Alabama with S.R. 20, S.R. 24, and S.R. 13.

State Route 231 (SR 231) is a long state highway in the U.S. state of Washington serving communities in Lincoln and Stevens counties. The highway, located entirely west of Spokane in the Inland Empire, serves Sprague, Edwall, Reardan, Springdale and Chewelah. The route extends from north of Sprague to a concurrency with (US 2) near Reardan and an intersection with south of Chewelah. Although SR 231 was established in 1964, the US 2 concurrency has existed as since 1909.

The road heads north leaving Tipton, passing through farmland with a few houses. SR 19 heads north until it meets U.S. Route 35 (US 35) and SR 22, east of Kokomo. The concurrency heads east passing through Greentown and an intersection with SR 213\. The concurrency ends when SR 19 turns north onto SR 13 and US 35/SR 22 keep heading east. SR 13 and SR 19 head north passing through farmland, with some houses.

At the beginning of Albany, the two highways become a freeway known as Liberty Expressway. At the intersection with US 19/SR 3, which join the concurrency, US 19 Business/US 82 Business/SR 520 Business head south into downtown Albany. At the next exit is SR 91/SR 133\. SR 133 joins the concurrency at this point. The five highways curve to the south, where US 82/SR 520 head east along with SR 300\.

In Forsyth, the highway meets SR 42 / SR 83\. SR 42 crosses US 41 while SR 83 has a brief concurrency with the highway within Forsyth. US 41 / SR 18 / SR 83 travel in a westerly path through the city before SR 83 eventually departs the concurrency travelling south. US 41 / SR 18 continue out of Forsyth travelling roughly to the west-northwest out of Monroe County into Lamar County and the southern limits of the Atlanta metropolitan area.

The eastern segment begins at an intersection with SR 15, on the south edge of La Fontaine. SR 218 heads east passing through farmland in rural Wabash County. The road enters Huntington County and passes through a rural intersection with SR 105, followed soon after by an intersection with SR 9. Past SR 9, SR 218 has a concurrency with SR 5, the concurrency has an interchange with Interstate 69, before bending to become north-south.

After passing SR 62 (Morgan Ave), the route exited Evansville and continued through suburban area. Near the northern end of the route, SR 57 started a brief concurrency with the Interstate Highway. I-164 ended at a cloverleaf interchange with I-64, and SR 57 continued north as a two-lane surface highway. However, in the mid 2000s, construction of I-69 north of I-64 began, and now continues north on a concurrency with SR 57\.

After passing through Willard, it sets out across the Pedernal Hills. In Encino, it begins a concurrency with US 285\. Just after crossing into Guadalupe County, US 54 joins the concurrency. The three highways pass through Vaughn and then go their separate ways; US 285 heads southeast towards the direction of Roswell, US 54 heads northeast towards both Santa Rosa and I-40, and US 60 heads east towards Clovis. US 54, US 60 and US 285 in Vaughn.

In Clovis, the home of Cannon Air Force Base, the highways meet up with US 70, which joins the concurrency. The three highways proceed through Texico, and just before the Texas state line, US 60 leaves the concurrency and heads northeast while US 70/US 84 continues eastward. For the distance of more than 300 miles (480 km) between Abo Pass and Amarillo, the highway parallels the Southern Transcon, one of the busiest transcontinental railroads in the west.

The road enters Richmond from the south, with a series of curves and a traffic light at SR 227\. US 27 and SR 227 begin a concurrency at this traffic light and both routes head north, heading for downtown Richmond. The concurrency passes over the Indiana Eastern Railroad tracks, as a four-lane undivided road. In downtown Richmond the roadway becomes one-way streets, begins after O street, with northbound on ninth street and southbound of eighth street.

US-59 enters Atchison and becomes part of a wrong-way concurrency with US-73 as it runs through the western portion of town. This concurrency ends at a junction with K-7, as US-73 leaves US-59 to become concurrent with K-7 and run south to Leavenworth. US-59 continues east on its own through the rest of town and crosses the Amelia Earhardt Memorial Bridge into Winthrop, Missouri, en route to St. Joseph.

The main features of FoundationDB included the following: ; Ordered key-value store : In addition to supporting standard key-based reads and writes, the ordering property enables range reads that can efficiently scan large swaths of data. ; Transactions : Transaction processing employs multiversion concurrency control for reads and optimistic concurrency for writes. Transactions can span multiple keys stored on multiple machines. ; ACID properties : FoundationDB guarantees serializable isolation and strong durability via redundant storage on disk before transactions are considered committed.

Of the four ACID properties in a DBMS (Database Management System), the isolation property is the one most often relaxed. When attempting to maintain the highest level of isolation, a DBMS usually acquires locks on data which may result in a loss of concurrency or implements multiversion concurrency control. This requires adding logic for the application to function correctly. Most DBMSs offer a number of transaction isolation levels, which control the degree of locking that occurs when selecting data.

Additionally, the ANSI phenomena do not distinguish between a number of types of isolation level behavior that are popular in commercial systems. There are also other criticisms concerning ANSI SQL's isolation definition, in that it encourages implementors to do "bad things": :... it relies in subtle ways on an assumption that a locking schema is used for concurrency control, as opposed to an optimistic or multi-version concurrency scheme. This implies that the proposed semantics are ill-defined.

The road crosses the Missouri River at Lake Francis Case, between the towns of Oacoma and Chamberlain, also crossing into Brule County. I-90 Business Loop runs from exit 260 at Oacoma to downtown Chamberlain across the Missouri River on the nearby Chamberlain Bridge, and returns to I-90 at exit 265. Beginning there is a short concurrency with SD 50 heading to Pukwana, and also in Brule County is another short concurrency with SD 45 starting at Kimball.

The simplicity of this approach to concurrency has resulted in temporal logic being the modal logic of choice for reasoning about concurrent systems with its aspects of synchronization, interference, independence, deadlock, livelock, fairness, etc. These concerns of concurrency would appear to be less central to linguistics, philosophy, and artificial intelligence, the areas in which dynamic logic is most often encountered nowadays. For a comprehensive treatment of dynamic logic see the book by David Harel et al. cited below.

At New Madrid US 62 begins a concurrency with US 61\. The combined US 61/62 goes north as far as Sikeston, where US 62 resumes its easterly direction. From Sikeston US 62 runs east to Charleston, where it is concurrent with Business I-57 for a short distance. After crossing I-57, US 62 becomes concurrent with US 60, this concurrency continues until US 60/62 leave Missouri by way of the Mississippi River bridge into Cairo Ill.

PA 970 once extended further south into Clearfield County and western Centre County. Its former southern terminus was at PA 350 in Sandy Ridge. It traveled northwest along present-day SR 3049 into Osceola Mills. In Osceola Mills, PA 970 ran along Curtin Street to PA 53 (Stone Street), turned left onto PA 53 forming a wrong-way concurrency with it along Stone Street and Sarah Street until leaving the concurrency by making a right onto Elizabeth Street.

This exit is the primary entrance to Heinz Field (home to the Steelers) and it is also a way for drivers to get to PNC Park (home to the Pirates). On the following exit, PA 65 makes a loop to the north and begins a concurrency with US 19 at a diamond interchange just north of the West End Bridge. The following two exits (one northbound and another southbound) ends the concurrency between US 19 and PA 65\.

From the beginning of the concurrency, the road crosses a railroad and intersects SR 155. US 97 / SR 20 then crosses over SR 155 on a bridge and crosses the Okanogan River. After the crossing, the roadway leaves Omak, along with the Colville Indian Reservation and intersects SR 215. From SR 215, the highway continues north past North Omak and Riverside to cross the Okanogan River again and enter Tonasket, where SR 20 leaves the concurrency.

The concurrency briefly overlaps SR 317 (Bonny Oaks Drive) before the highways leave SR 317 (Old Lee Highway) and become concurrent to I-75/US 74. During this intersection, Tennessee State Route 2 becomes a Primary route for the first time. The concurrency goes northeast for several miles before US 64, US 11, and SR 2 leave and once again become Lee Highway as they pass Through Ooltewah and intersect SR 321 (Main Street/Old Lee Highway).

SH-33 overlaps US-283 to mile 16.9, where it begins a three-route concurrency with SH-47, which leads east to Putnam. Along the three-route concurrency, the highway passes through the National Grassland, and at milestone 24.8 SH-33 swings off to the left while US-283 and SH-47 continues toward Cheyenne. At mile 29.5, SH-33 passes Strong City, and at mile 42.7 passes the town of Hammon with its intersection with SH-34.

Business US 60 in Neosho begins at the intersection of US 60 and U.S. Route 71 Business. The road briefly forms a concurrency with Business US 71, before turning off and heading north on Neosho Boulevard. At Harmony Street, the road begins another concurrency with Route 86. Neosho Boulevard curves east becoming Coler Street, then Business US 60 turns north on College Street (leaving Route 86), which rejoins the main highway northeast of the city at an interchange.

At 67.6 miles (108 km) in length, the eastern overlap between US 20 and NY 5 is the second-longest surface-road concurrency in New York state, behind only the concurrency of I-86 and NY 17 in the Southern Tier. reference and reassurance markers on NY 5 eastbound are visible. Maintenance of the majority of NY 5's is performed by the New York State Department of Transportation. However, locally owned and maintained sections exist in six cities.

At the beginning of Albany, the two highways become a freeway known as Liberty Expressway. At the intersection with US 19/SR 3, which join the concurrency, US 19 Business/US 82 Business/SR 520 Business head south into downtown Albany. At the next exit is SR 91/SR 133\. SR 133 joins the concurrency at this point. The five highways curve to the south, where US 82/SR 520 head east along with SR 300\.

The two highways form a concurrency near the Greene–Pitt county line. Just before the highway crosses into Pitt County, the concurrency ends and NC 121 heads northeast towards Farmville. Now in Pitt County, NC 121 travels east across farmlands west of the town limits of Farmville. Upon entering the town, the name of the road becomes West Wilson Street and the highway reaches US 258 Business (US 258 Bus.) at May Boulevard and Turnage Street.

In North Andover, Route 114 crosses Route 133 before beginning a concurrency with Route 125 which lasts for over half a mile, passing Merrimack College in the process. It then continues through the town into Middleton, where it has a short wrong-way concurrency with Route 62 in the center of town. From Middleton, Route 114 heads into Danvers. In Danvers, Route 114 has interchanges with U.S. Route 1 and I-95 in quick succession before entering into Peabody.

At Columbus, US-160 begins a concurrency with U.S. Route 69, which goes east to Crestline, then north to Frontenac, Kansas. Also at Crestline, it picks up a second concurrency with U.S. Route 400, which goes north and ends just south of Pittsburg, Kansas. After Frontenac, it turns east and enters Missouri. The section of US-160 in Harper, from K-14 to slightly east of end of overlap with K-2 is maintained by the city.

K-116 does connect to the National Highway System at each terminus, US-75 and US-59. 2017 Annual average daily traffic (AADT) on K-116 ranged from 625 slightly west of the eastern terminus to 1820 slightly east of Holton.

BL I-94 was rerouted and cosigned with Bus. US 27 along Michigan Avenue and the new freeway on the west end. The concurrency with Bus. US 27 was removed in 1972.

By default, the implementation can choose, which provides an easy way to take advantage of hardware concurrency without oversubscription, and provides some of the advantages of a thread pool for simple usages.

This gave both highways straighter courses and resolved the wrong-way concurrency. However, the change was rescinded on August 13, 1956. Two minor realignments were done to SH-47 in the 1960s.

U.S. Route 74 Business (US 74 Bus) was established in 1975 to replace the old mainline US 74 through Chadbourn and Whiteville. The route is mostly in concurrency with US 76 Business.

Processing resources are sometimes assigned to specific activities to improve concurrency. On a server with eight processors, six could be reserved for the DBMS to maximize available processing resources for the database.

The road just enters northern Worthington Springs, Florida at the intersection with State Road 121, then follows that route south in a hidden concurrency with the state road it was originally part of.

At Km 30.1, Highway 711 turns east again departing from the concurrency. The intersection with Highway 606 occurs at Km 40.0. At Km 61.1, Highway 711 is the junction with Highway 617 North.

It leaves the county near Sikesville. It enters Randolph County. It maintains a short east-to-west path to SR 22 in Wadley. It maintains a concurrency with it until they reach Louina.

Termite Scheme is a variant of Scheme implemented on Gambit-C. Termite is intended for distributed computing, it offers a simple and powerful message passing model of concurrency, inspired by that of Erlang.

The route joins I-39 north of Portage. There is a short concurrency with WIS 23 from Endeavor to WIS 82 near Oxford. They stay joined until I-39 ends at WIS 29\.

North of Tuscaloosa and Northport, SR 69 continues northward as it heads towards Jasper. At Jasper, SR 69 and SR 5 share a wrong- way concurrency along the former route of US 78.

Before leaving Donegal Township, PA 31 approaches the eastern terminus of the concurrency with PA 381. This is the last major intersection before PA 31 winds its way through rural Pennsylvania to Somerset.

South of the park, they intersect SC 19 (Whiskey Road). Here, SC 19 Truck joins the concurrency. They curve to the west-southwest and meet Silver Bluff Road, where SC 302 turns left.

At the intersection with I-30, US 69 becomes concurrent with US 380 at its terminus. The concurrency continues around the southern and western sides of Greenville until an intersection with Spur 302. At that intersection, US 380 heads west while US 69 continues north, until it reaches the northern end of its Business route, which has passed through the downtown Greenville area, then US 69 turns northwest, from Greenville to Leonard, where it encounters a brief concurrency with SH 78.

They curve to the northwest, then curve back to the northeast. After a brief entrance into Johnson County, and a longer re-entrance to Emanuel County, the concurrency enters Johnson County again. They continue to the northeast and then curve to the northwest to the town of Kite, where they meet SR 57\. They continue to the north and begin a gradual curve to the northeast to enter Jefferson County. The routes meet US 319/SR 78, which join the concurrency.

US 231, which has been joined by US 52 by this point, continues north for a few miles, then turns westbound. US 231 then leaves the concurrency, while US 52 continues northwest and US 231 heads due north. North of US 52, the highway becomes a two-lane rural highway passing through farmland. US 231 has an interchange with I–65; this is the first of four interchanges with I–65. The route begins a concurrency with US 24 in Wolcott.

Eastbound entering Sandisfield The route begins in Monterey, at its intersection with routes 23 and 183. The section from there to New Marlborough (which is a concurrency with Route 183) primarily takes a southeastern path that passes several stretches of farmland. In New Marlborough, Route 57 splits from Route 183 and follows a mainly easterly route with frequent curves, passing more farmland. During this stretch, there is a brief concurrency with Route 8 in Sandisfield to cross the Farmington River's west branch.

SH-6 was extended to the south on July 7, 1975, bringing it to Altus by way of a concurrency with US-283, where it joined US-62 in another concurrency, headed west. West of Altus, the route split off and headed southwest to the Texas state line. In addition to the U.S. routes, SH-6 was concurrent with SH-44 between that route's current southern terminus and Eldorado, where it ended; thereafter, SH-6 followed SH-34 to the Red River.

The new alignment opened as an undivided two-lane freeway in November 2004; it is expected to expand to a full 4-lane divided highway, and to extend to past Caledonia, by some time in the 2010s. As the road meets Highway 403, Highway 6 merges with Highway 403, and there is a concurrency for 17 kilometres within Hamilton. The concurrency ends at the Highway 6 junction, at the Hamilton/Burlington boundary, near the Royal Botanical Gardens where Highway 6 turns northward.

In 2000, NC 94 was extended both directions: At Lake Comfort, it goes west on a concurrency with US 264 to Swan Quarter, where it then splits off onto Main Street and continues till it reaches NC 45, its current southern terminus. At Columbia, NC 94 goes west on a concurrency with US 64 near Pea Ridge, where it then switches concurrences with NC 32\. Traveling north, it crosses over the Albemarle Sound, then separates from NC 32 near St. Johns.

On the northeastern edge of the city limits, the concurrency begins a gradual curve to the southeast, traveling north of Brooks Lake and the Brooks Lake Dam and southwest of a branch of the Oglethrope County Library. They also pass Oglethorpe County High School. Immediately after entering Lexington, US 78/SR 10 intersect SR 22 (Comer Road), which joins the currency. The three highways travel to the south-southeast to an intersection with SR 77 (Union Point Road), which also joins the concurrency.

From Shelbyville, US 41A continues northwest into the southwestern portion of Rutherford County. Further north, it then enters eastern Williamson County, where it begins a concurrency with US 31A that lasts from just south of Triune near the I-840 Exit 42 interchange, through Nolensville, and into Davidson County and the Metro Nashville area. In downtown Nashville, US 31A ends, while US 41A continues and begins a brief concurrency with US 31, US 41, US 431, and SR 6 on Eighth Avenue.

Between East Ash Street and East Railroad Avenue, the highway curves to the northeast with that same Southern Railway line earlier flanking the west side, although the tracks begin to move away from the road north of unmarked Emergency Route 105\. The business route ends at US 23/SR 87, but US 129 Alt. joins the route in a concurrency into Macon, while SR 112 travels concurrently only as far as north into Royal along the same concurrency until branching off towards Milledgeville.

Signage on the 14th Street Viaduct at the western terminus of the concurrency of I-78 and Route 139 in Jersey City Route 139 is essentially three distinct, but connected highways: the upper level, the lower level, and the Holland Tunnel approach (the Interstate 78 concurrency). NJDOT officially charts the lower and upper levels as independent highways, with the lower level considered Route 139 with a notation that the highway then coincides with I-78, and the upper level considered Route 139U.

On the northeastern edge of the city limits, the concurrency begins a gradual curve to the southeast, traveling north of Brooks Lake and the Brooks Lake Dam and southwest of a branch of the Oglethrope County Library. They also pass Oglethorpe County High School. Immediately after entering Lexington, US 78/SR 10 intersect SR 22 (Comer Road), which joins the currency. The three highways travel to the south-southeast to an intersection with SR 77 (Union Point Road), which also joins the concurrency.

From there, Canal Street becomes Martin Luther King, Junior Boulevard. This segment of the highway shifts between southeast and east trajectories and, at one point, crosses an at-grade former Central of Georgia Railway line. MLK Jr Boulevard travels southeast for the last time and ends at a short concurrency with US 27/SR 1, where SR 100 turns south and US 278/SR 6 turns north. That concurrency ends at an overpass with two connecting roads on the southwest and northeast corners.

The road parallels a river, before having an interchange with the eastern end of the US 250 concurrency and the eastern end of the SR 3 concurrency. US 30 leaves Wooster and passes through farmland. The highway has a traffic signal at a T-intersection with SR 57\. The route enters Dalton and has a T-intersection with the western terminus of US 30 Alternate. US 30 by-passes most of Dalton to the south, having a traffic signal at SR 94\.

The concurrency with SR 154 ends, when US 30 and SR 45 turn southeasterly and SR 154 continues east towards Elkton and SR 11. The highway leaves Lisbon and passes through woodland as a two-lane highway. At West Point, US 30 turns easterly and SR 45 continues towards the south, just before an interchange with SR 11. US 30 enters SR 11 and the concurrency heads towards the southeast, as a four-lane divided highway with limited access, passing through woodland.

Highway 145 becomes Edmonds Avenue in McCrory, running north to an intersection with US Highway 64 Business (US 64B, Raney Avenue), and forming a brief concurrency to Poplar Avenue. After the concurrency ends, Highway 145 crosses the Union Pacific Railway tracks and enters the McCrory Commercial Historic District, listed on the National Register of Historic Places. North of downtown McCrory, Highway 145 passes through a residential area before an intersection with US 64, with the roadway continuing north as Highway 17 to Newport.

The route heads through an S-curve to stay near the creek as it continues north. Near the community of Willow Wood, SR 378 intersects and forms a concurrency with SR 217. The two routes wind their way west for about before SR 378 breaks off of the concurrency to continue heading north along the creek's path. Now heading in a more north-northwest direction for the remainder of the route, SR 378 is briefly within the boundaries of the Wayne National Forest.

Signage indicating closings The road then passes the entrance to White Sands National Park, and shortly after that passes the southern end of Holloman Air Force Base. It then turns northbound, and picks up a concurrency with U.S. 54 upon entering Alamogordo. On the north end of Alamogordo, US54/US70 intersects the beginning of U.S. Route 82 near La Luz. The concurrency with US 54 lasts until Tularosa, and the highway remains divided until US 70 and US 54 diverge.

After Fifth Avenue, the road begins to curve to the northwest, and by 15th Avenue, the concurrency with US 129 ends as the road moves towards more of a northwest angle, taking hidden SR 100 with it. SR 6 and US 41 return straight west as it leaves the city until CR 148 (Northwest 86th Boulevard), where they begin to curve northwest again. Shortly after this curve, as well as another bridge over the Alapaha River, the concurrency with SR 6 ends.

By October 1929, SR 4 was designated on the current path. The eastern terminus of SR 32 was truncated to Alma. SR 15's southern terminus was removed from US 1 and truncated to the northern end of its former concurrency with US 1 north of Alma, at what is the current northern end of the concurrency that US 1/SR 4 have with US 23\. SR 24's Louisville–Augusta segment was shifted to the southeast to travel between Louisville and Waynesboro.

Asynchronous message passing may be reliable or unreliable (sometimes referred to as "send and pray"). Message-passing concurrency tends to be far easier to reason about than shared-memory concurrency, and is typically considered a more robust form of concurrent programming. A wide variety of mathematical theories to understand and analyze message-passing systems are available, including the actor model, and various process calculi. Message passing can be efficiently implemented via symmetric multiprocessing, with or without shared memory cache coherence.

Highway 125 at George's Creek just north of the US 62/US 412 concurrency The route begins at Arkansas Highway 235 near Bruno and runs north past the historic Eros School Building to intersect US 62/US 412 in Pyatt. The routes become concurrent until George's Creek, near the George's Creek Cemetery. Highway 125 winds north through farms and trees until forming a concurrency with Highway 14 near Lakeway. Highway 14 turns west north of Lakeway, with Highway 125 continuing north through Peel.

After the bridge, US 221/SR 135 only has intersections with a boat launching area and some minor dirt driveways until the blinker-light intersection with South Old River Road (Montgomery CR 150). Further north it passes through the eastern edge of Charlotteville. Entering Uvalda, the street name changes to First Street. As it approaches Main Street, the concurrency with SR 135 ends, and US 221 turns left at East Main Street to join another concurrency with Georgia State Route 56.

SR 753 turns right onto US 50 forming a concurrency for about . Upon entering Rainsboro, SR 753 breaks off of US 50 at Barrett Mills Road and heads north towards New Petersburg. The route makes a sharp curve to the northeast at New Petersburg and heads through Paint Creek State Park and crosses Walnut Creek on a bridge. Shortly after the park, the route enters Greenfield, the name of the route becomes 7th Street and forms a concurrency with SR 138.

US 41 looking north into Georgia from across the border with Florida US 41 enters Georgia paired with a concurrency with SR 7 southeast of Valdosta. South of the border between the states, US 41 shares a concurrency with unsigned Florida State Road 25; however that route ends upon entering Georgia. Upon entering Georgia, US 41 / SR 7 briefly pass through the southeastern corner of Echols County. The highway enters Lowndes County while heading towards Valdosta, the county seat of Lowndes.

US 231 enters Tennessee from Alabama in a concurrency with US 431 until it reaches Fayetteville. North of there it runs through Shelbyville and later passes through the eastern part of the Nashville metro area, passing through the cities of Murfreesboro and Lebanon. By the time it reaches Bethpage, it joins U.S. Route 31E in another concurrency to the northeast before finally crossing the Kentucky State Line north of Westmoreland. The route is approximately from Tennessee's northern border to its southern border.

At the intersection with I-30, US 69 becomes concurrent with US 380 at its terminus. The concurrency continues around the southern and western sides of Greenville until an intersection with Spur 302. At that intersection, US 380 heads west while US 69 continues north, until it reaches the northern end of its Business route, which has passed through the downtown Greenville area, then US 69 turns northwest, from Greenville to Leonard, where it encounters a brief concurrency with SH 78.

Also at this point, the PA 58/PA 258 concurrency is split – eastbound follows S. Diamond St., and westbound follows N. Diamond St. in the middle of town. At the east end of the “square,” the concurrency ends as Route 258 heads southward and PA 58 continues east, then later turns southeast. It crosses both I-80 and I-79 near the interchange of the two interstates, just over from Mercer, and enters the borough of Grove City about later.

In Grove City, the route intersects with the southern terminus of the PA Route 173/PA Route 208 concurrency, and overlaps with Route 173, continuing southeast. About later, the concurrency ends; Route 173 continues south, and PA 58 continues southeast just over to the Butler county line after spending 39 miles in Mercer County. A mile after entering Butler County, PA 58 intersects with PA Route 8 in the borough of Harrisville. The route then travels nearly to intersect with PA Route 308.

SR 85 heads northeasterly from its southern terminus in Geneva. The highway travels through rural areas of Geneva County, then crosses into the southwestern corner of Dale County. Near Clayhatchee, the highway briefly turns eastward as it begins a brief concurrency with SR 92\. The highway turns northward at the end of the concurrency, then continues through Daleville, where it crosses U.S. Route 84 (US 84) then reaches its northern terminus at a gate on the south side of Fort Rucker.

In Wentzville, the route interchanges with I‑70\. The western end of I‑64 and the northern end of the concurrency with US 40 is here. The Avenue of the Saints continues north as just US 61, intersects with the western end of I‑72 in Hannibal, reaches the northern terminus of its concurrency with US 61, then crosses the Des Moines River into Iowa. The Avenue of the Saints is co-signed with Missouri Route 27 to the Iowa state line.

A short distance later, SR 281 intersects SR 18 and the two routes form a concurrency and head east out of the city past a General Motors factory. After , the SR 18 concurrency ends and SR 281 continues due east. Outside of the Defiance area, the route's surroundings becomes much more agricultural. After exiting Defiance County, it enters Henry County. SR 281 does not pass through any incorporated villages through Henry County, but it intersects State Routes 108, 109, and 65.

US 11 and US 80 at the Alabama state line. US 80 and US 11 cross the Mississippi-Alabama state line east of Toomsuba, Mississippi, sharing a concurrency starting in Meridian, Mississippi. The two U.S. Highways are joined by a hidden Alabama State Route 7 designation starting at the state line. Heading northeast, the route passes through the town of Cuba and intersections with Sumter County Routes 76 and 10. CR 10 shares a small concurrency with US 11/US 80 through Cuba.

In various plane geometries the notion of interchanging the roles of "points" and "lines" while preserving the relationship between them is called plane duality. Given a set of collinear points, by plane duality we obtain a set of lines all of which meet at a common point. The property that this set of lines has (meeting at a common point) is called concurrency, and the lines are said to be concurrent lines. Thus, concurrency is the plane dual notion to collinearity.

US 49 enters Arkansas near Helena-West Helena in Phillips County. US 49 Business runs around the north part of the city, with the main route meeting AR 242 in the southern portion. US 49 continues west to Walnut Corner where the route meets AR 1 (and briefly AR 316). The US 49/AR 1 concurrency ends in Marvell, and US 49 enters Monroe County. Upon entering Monroe County, US 49 turns north to begin a concurrency with AR 39.

After leaving Yakima, the highway enters Selah and interchanges with SR 823 and Rest Haven Road and then later leaves the city after interchanging Selah Road to cross Selah Creek on the Fred G. Redmon Bridge. Approaching Ellensburg, the roadway interchanges with SR 821 at exit 26, Military Road at exit 11 and the northern end of SR 821 at exit 3 before entering Ellensburg. I-82 later ends its concurrency and route at I-90, were a brief concurrency begins.

In Greenville, Route 18 intersects with the northern terminus of PA Route 846 just before its junction with PA Route 358. Here, the two routes overlap, heading eastward, and cross the Shenango River once again, before intersecting about later with PA Route 58, which joins the concurrency for about a quarter mile. Routes 18 and 58 then leave Route 358 and head northward. Less than a half mile later, Route 18 leaves the concurrency, turning northeastward, then northward, leaving Greenville.

As It once again intersects I-24 and then intersects US 11/SR 38 (Birmingham Highway). SR 38 terminates her while US 11 joins the concurrency. They then intersect SR 318 (Old Wauhatchie Pike), which is a short connection to SR 148 and Lookout Mountain and then continues eastward into Chattanooga. In Chattanooga, SR 17 (Tennessee Avenue), which also connects to Lookout Mountain and also SR 58, enters the concurrency as it becomes Broad Street and travels northeast into downtown.

Mike Shields has been an academic in the Department of Computing at the University of Surrey in Guildford, southern England. His research contributions have been in theoretical computer science, especially concerning concurrency. In particular, he has written books on automata theory and the semantics of parallel computing. A meeting was held in 2006 at the British Computer Society's offices in London to celebrate Shields' contribution to computer science (his "innovative and elegant foundational work on models of concurrency") on his retirement.

Multiversion concurrency control is described in some detail in the 1981 paper "Concurrency Control in Distributed Database Systems" by Phil Bernstein and Nathan Goodman, then employed by the Computer Corporation of America. Bernstein and Goodman's paper cites a 1978 dissertation by David P. Reed which quite clearly describes MVCC and claims it as an original work. The first shipping, commercial database software product featuring MVCC was Digital's VAX Rdb/ELN. The second was InterBase, both of which are still active, commercial products.

Some aspects of the MPI's future appear solid; others less so. The MPI Forum reconvened in 2007, to clarify some MPI-2 issues and explore developments for a possible MPI-3, which resulted in versions MPI-3.0 (September 2012) and MPI-3.1 (June 2015). Architectures are changing, with greater internal concurrency (multi-core), better fine-grain concurrency control (threading, affinity), and more levels of memory hierarchy. Multithreaded programs can take advantage of these developments more easily than single-threaded applications.

LA 47 is classified by the Louisiana Department of Transportation and Development (La DOTD) as an urban principal arterial south of I-510 and an urban interstate over the I-510 concurrency. The remainder of the route is generally classified as an urban minor arterial. Daily traffic volume in 2013 peaked at 28,500 vehicles between Chalmette and the I-510 concurrency. North of I-10, figures dropped off sharply to a low of 5,600 along much of the Hayne Boulevard segment.

At this interchange with I-94 the Tri-State Tollway and I-294 both end, with I-94 running concurrent with I-80 towards the east. The concurrency between I-80 and I-94 travels on a freeway locally known as the Kingery Expressway. The interstate has a single-point urban interchange (SPUI) with IL 83 and the western end of US 6 concurrency. East of US 6 exit the freeway become a ten- lane interstate, passing near residential properties.

It turns west at the Franklin County line and overlaps the border until it enters Coffey County, where it continues west toward Waverly. Leaving the town, K-31 heads north again toward Interstate 35 (I-35), and Melvern. It shares a short wrong-way concurrency with I-35 before arriving in Melvern, where it once again turns west.K-31 concurrent with I-35 and US-50 The highway begins a concurrency with US-75, where it heads toward, and passes through Lyndon.

Route 67 is mostly a two-lane surface road, with a divided four-lane section in Southbury. It begins in New Milford as a 0.5 mile concurrency with US 202 as the latter leaves a concurrency with US 7. After crossing the Housatonic River into the center of town, Route 67 breaks away to the southeast. In Bridgewater, it meets the northern end of Route 133. In Roxbury, it meets the southern end of Route 199 and the western end of Route 317. It then clips a corner of Woodbury before passing into New Haven County and the town of Southbury, where it passes the northern end of Route 172 before joining US 6 for a 4 lane divided 1.6 mile concurrency leading to a junction with I-84 at Exit 15.

East of Paoli SR 56 heads towards Salem passing through an intersection with State Road 337 before passing by the entrance to Salem Speedway. SR 56 and State Road 60 have a concurrency from the west side of Salem to downtown Salem. SR 56 leaves Salem heading northeast, then turning east near the southern terminus of State Road 39 (SR 39). After SR 39, SR 56 passing over Interstate 65 (I-65). Then SR 56 enters Scottsburg where SR 56 has an intersection with U.S. Route 31. After leaving Scottsburg, SR 56 has a concurrency with State Road 203 and State Road 3. Then SR 56 heads toward Hanover where SR 56 and State Road 62 (SR 62) has a concurrency. East of Hanover SR 62 turns north and SR 56 heads east.

Turning north and northwest, the section between Richmond Dale and Chillicothe includes a large cut through a ridge and provides westbound motorists with a panoramic view of the Scioto River valley. Southeast of Chillicothe, westbound US 50 joins US 35 in a concurrency at a hybrid interchange; similar to a diamond interchange, the exit ramp from US 35 east carrying US 50 east becomes a two-way road, curves around and crosses over US 35 about east; the other ramps connect to this overpass. Next, US 50 west leaves the concurrency at a partial interchange at Eastern Avenue; there is only a westbound exit and an eastbound entrance. Then, the US 23 north freeway joins US 35 in a concurrency at a partial-Y interchange; there is an eastbound exit and a westbound left entrance.

Originally, NY 391 terminated at NY 75 in Hamburg, resulting in an extraneous overlap with US 62 for two blocks along Main Street. NY 391 was truncated to the eastern end of the concurrency .

On February 10, 1966, FM 213 was extended west to SH 214, replacing FM 396. That same day, FM 303 was extended south replacing FM 1312, and a concurrency with FM 303 was created.

At Eudora, the concurrency ends. Seventeen miles east of Eudora, the highway joins Route 13 for one mile (1.6 km), then turns east. The highway continues east to US 65 where the highway ends.

Just before entering Bartow, they intersect SR 242\. In town, US 319/SR 78 depart to the east. US 221/SR 171 continue to the north, until they meet SR 24, which joins the concurrency.

The M-28A designation was also changed to Bus. M-28 at this time on the map, creating an M-117/Bus. M-28 concurrency in place of the older M-28A/M-48 one.

Spur 80 is located in Arp. It runs from SH 135 south to CR 294. The route has a concurrency with CR 294. Spur 80 was designated on September 25, 1939 on the current route.

SR 421 soon arrives at its endpoint at an interchange that doubles as the eastern split of the US 42/US 224 concurrency. No portion of SR 421 is included within the National Highway System.

Bala, Gwynedd. The A494 diverges from the concurrency with the A5 at the road junction at Druid, Denbighshire. It then heads south west for to Dolgellau, Gwynedd. This section of the A494 remains single carriageway.

Business U.S. Route 98 was a short business route of U.S. Routes 98 in Lakeland, Florida between the early 1960s and 1999. It also included a concurrency with former US Bus 92 along Main Street.

To avoid blocking during updates, Interbase uses multiversion concurrency control instead of locks. Each transaction will create a version of the record. Upon the write step, the update will fail rather than be blocked initially.

Since then no update to the standard has been published. Various extensions and improvements to Common Lisp (examples are Unicode, Concurrency, CLOS-based IO) have been provided by implementations and libraries (many available via Quicklisp).

The concurrency, an important and busy regional artery, continues past Newark Liberty International Airport and over the Pulaski Skyway, finally leaving the state along with US 1 and I-95 via the George Washington Bridge.

The route curves to the east and meets SR 305\. It curves to the southeast before heading east-southeast. The highway begins a concurrency with SR 24 just before entering Waynesboro. About later, SR 56\.

Upon entering the Wayne National Forest, the route generally parallels the Little Muskingum River. About from the terminus, SR 26 encounters its first state highway, SR 260. SR 26 and SR 260 form a concurrency.

Established in 1953 when mainline US 15 was bypassed around Chapel Hill. US 15A, in concurrency with US 501A, traversed on Columbia Street and Franklin Street. In 1960, it was renumbered as US 15 Business.

At Hansonville, US 58 Alt. and US 19 form a concurrency heading southeast towards Abingdon. Northwest of the town, US 58 Alt. becomes an independent highway briefly until reaching US 11 (Main Street) in Abingdon.

Record based patterns work poorly in distributed systems especially where concurrency is impossible (e.g. offline). i.e. two updates both may have one field that is correct but only one of the two records can win.

Beginning from the end of the US 49B concurrency to Highway 1, the route is designated as part of the Mississippi River Trail, a bike route from New Orleans to Minnesota along the Mississippi River.

After the US 6 concurrency SR 3, becomes a two–lane rural highway heading due North, until Mongo where the road turns northwest. Entering into Brighton, SR 3 reaches its northern terminus at SR 120.

It turns east with Routes 49 and 138, then continues east in a concurrency with Route 138. After leaving Route 138, Route 165 continues east to the Rhode Island state line, meeting RI Route 165.

Established in 1953 when mainline US 501 was bypassed around Chapel Hill. US 501A, in concurrency with US 15A, traversed on Columbia Street and Franklin Street. In 1960, it was renumbered as US 501 Business.

Route 122A is a southeast-northwest state highway in Massachusetts, in the United States. It is an alternate route of Massachusetts Route 122, with a mile-long concurrency with its parent route in downtown Worcester.

In object-oriented and functional programming, an immutable object (unchangeable object) is an object whose state cannot be modified after it is created.Goetz et al. Java Concurrency in Practice. Addison Wesley Professional, 2006, Section 3.4.

CR 571 then leaves the concurrency by turning to the west on Stockton Street. The route passes more residences, the Stockton Street Historic District, before crossing back into East Windsor Township and intersecting US 130.

US 6 and US 202 travel concurrently to Danbury, Connecticut, and US 6/202 and NY 22 have a short concurrency. : in Brewster ;Connecticut : in Danbury. The highways travel concurrently through the city. : in Newtown.

For high availability database objects are often replicated. Updates of replicas of a same database object need to be kept synchronized. This may affect the way concurrency control is done (e.g., Gray et al. 1996).

US 395 was re-aligned to a concurrency with I-82 in 1985, crossing the Columbia River on the Umatilla Bridge and having a shorter concurrency with US 730. The old route of US 395 from Cold Springs Junction to Pendleton, part of Pendleton-Cold Springs Highway No. 36, became Oregon Route 37. The highway's eastern terminus in Wallula is planned to be moved further north to a new interchange with US 12 after the completion of the Burbank–Walla Walla divided highway in 2020.

It shares a quarter-mile long concurrency with Route 28 before continuing eastward through the town into Essex County and the town of Middleton. In Middleton, Route 62 heads north one final time, sharing a short wrong-way concurrency with Route 114 before turning eastward, crossing the Ipswich River before finally turning southeastward into the town of Danvers. In Danvers, the route has consecutive interchanges with U.S. Route 1 (along the Newburyport Turnpike) and I-95, just north of the former Danvers State Hospital site.

US 431 runs concurrently with US 231 upon entry into Tennessee from Madison County, Alabama, where the concurrency begins. The state line also marks the beginning of a secret concurrency with, and the southern terminus of unsigned Tennessee State Route 10. The two U.S. routes plus SR 10 do not split until they reach downtown Fayetteville. While US 231 goes into a north-northeasterly path, US 431 turns northwest into Marshall County, bypassing around Lewisburg, and later into northeastern Maury and into Williamson County.

The route continues east, crossing over Clear Creek and ends north of Shelbyville at an intersection with KY 55 Business. North of the Shelbyville Bypass, KY 55 becomes Eminence Pike and narrows to two-lanes as it heads north passing open fields and houses before entering into Henry County roughly further north. In Henry County, KY 55 enters the city of Eminence and forms a concurrency with KY 22 for . It continues north out of town and forms a concurrency with US 421 north of KY 22.

In Jackson, the highway is concurrent with I-20 for three exits, and US 51 leaves the concurrency after I-55's concurrency with I-20 begins. I-55 continues north on the eastern side of Jackson, and meets the northern terminus of I-220 near Ridgeland. The highway then parallels US 51 until the U.S. route crosses over to the western side of the interstate in Grenada. I-55 intersects US 278 at Batesville, and it becomes concurrent with I-69 north of Hernando.

About 1.3 miles later, SR 20 meets US 90/Tennessee Street and turns right into a hidden concurrency. The two roads head southeast along Tennessee St before drifting northeast and then east. After intersecting Stadium Drive, the roads head southeast again, passing along the north side of Florida State University. Heading directly east into downtown, the routes meet US 27/SR 61/Monroe Street, where SR 20 turns right onto these routes into another hidden concurrency, while US 90 continues as Tennessee Street heading east.

In Bradford, Route 125 meets a connector road between it and I-495 which passes through an industrial area. The route then continues through the Bradford area before crossing the Merrimack River at the Basiliere Bridge. Once it crosses the bridge into the downtown Haverhill area, Route 125 crosses Route 113 before sharing a one-block concurrency with Route 97 and a two-block concurrency with Route 110 in quick succession. The route then turns more northwesterly, crossing I-495 directly at Exits 51 A-B.

The road commences in Forbes at a junction with the Gooloogong-Forbes Road (Lachlan Valley Way). It continues south over relatively flat countryside, crossing the Bundaburrah Creek and Ooma Creek, before it forms concurrency with the Mid-Western Highway west of . The concurrent road heads east into the town of Grenfell, where the concurrency terminates as the Henry Lawson Way heads south (on Weddin Street) towards Young through highly undulating countryside. It reaches its terminus (as Iandra Street) at a junction with the Olympic Highway.

SR 137 begins in Cusseta, within Chattahoochee County, at an intersection with Wells Street, which used to also bear the designation of SR 520 Business. It runs along Broad Street, which also used to bear the SR 520 Business designation, for nearly , until SR 137 heads northeast. Just northeast of Cusseta, it has a very brief concurrency with SR 26\. It continues to the northeast and cuts across the southeastern corner of Fort Benning and begins a concurrency with SR 355, just before leaving the fort.

KY 12 begins at a junction with KY 43 near Christianburg and travels east toward Bagdad passing through a rural area of mostly farmland. In Bagdad KY 12 forms a short concurrency with KY 395 before heading east out of Bagdad. east of KY 395 the route forms a brief concurrency with KY 1005 and turns toward the northeast. After a few tenths of a mile KY 12 turns back toward the east and enters Franklin County where it becomes more narrow and curvy.

This road was the former State Road 200A and decommissioned U.S. Route 301 Alternate. Another county alternate of a state highway that the road intersects with is CR 25A (Northwest Gainesville Road), which runs northwest through towns such as Zuber, Lowell, and Reddick. East of Zuber, the road intersects SR 326, which originally had a short concurrency, but now directly crosses US 301-441. South of the intersection with CR 329 is an interchange with U.S. Route 441 near Sparr, where the US 301-441 concurrency ends.

This spur runs next to the beginning of the concurrency with State Road 267 and CR 268 once again. The concurrency with SR 267 may have been in the process of being eliminated though, as a four-lane stub extends a block north of US 90\. US 90/SRs 12/65/267/CR 268 enter the Quincy Historic District at Stewart Street. Four blocks later at Adams Street, SR 267 leave US 90 to the north, and CR 268 turns in the opposite direction.

The route then turns east and joins SR 50A in a concurrency, while SR 700 continues south along Ponce De Leon Boulevard. Shortly after this new concurrency, it makes a right along North Mildred Avenue, for eastbound traffic only, and both merge with US 41. Between North Mildred Avenue and May Avenue, eastbound SR 50A, US 41, and US 98 are concurrent along Broad Street, while westbound SR 50A, US 41, and US 98 are concurrent along East Jefferson Avenue, then West Jefferson Avenue.

There, it begins a concurrency with SR 111\. Just over later, they cross over the Ochlockonee River and travel along the Riverside–Moultrie city line. A short distance later, also on the city line, is the end of the concurrency, with SR 111 departing on West Bypass NW. SR 37 continues to travel along the city line until the intersection with 11th Street SW/Martin Luther King, Jr. Drive NW, where it re-enters Moultrie proper. In downtown Moultrie is an intersection with US 319 Bus.

Monroe. This segment is also an Arkansas Heritage Trail Trail of Tears route. US 79 continues northward from Louisiana into Emerson and then Magnolia, where it has a brief concurrency with US 82 through the city. From here, the route turns to the northeast, through Camden, where it intersects US 278, and Fordyce, in which it has a brief concurrency with US 167\. East of Kingsland, the highway travels in a more northerly direction as it prepares to enter the Pine Bluff metropolitan area.

This concurrency ends when the highway meets SR 138, SR 54 leaves the concurrency to join SR 138 headed east towards the center of Jonesboro. North of Jonesboro, Tara Boulevard merges directly into I-75 while US 19 / US 41 / SR 3 veers to the north-northeast forming the remainder of a full interchange with the interstate highway. From this point northward US 19 / US 41 / SR 3 is known as Old Dixie Highway. Old Dixie Highway continues north through Clayton County, passing through Forest Park.

In Alameda County, it runs northward through the city of Newark, where it begins a concurrency southwards with I-880 for about one mile. Both interchanges with I-880 are partial cloverleaf interchanges. Upon separation, however, the route is not built to freeway standards as it enters the city of Fremont, following the streets of Thornton Ave, Fremont Blvd, Peralta Blvd, and Mowry Ave, which after, it has a short concurrency northwards with SR 238. SR 84 then leaves Fremont through the historic Sunol Valley.

SR 42 begins at an intersection with SR 49/SR 540 (Peach Parkway) in Byron, in Peach County. It stairsteps its way to the west and northwest, crossing into Crawford County along the way. In Knoxville, it intersects US 80/SR 22 (East Crusselle Street). The three highways head concurrent to the west, into Roberta, where they intersect US 341/SR 7 (South Dugger Avenue). Here, SR 42 leaves the concurrency of US 80/SR 22 and joins the concurrency of US 341/SR 7\.

This section is the most heavily traveled section of highway in Tennessee, with an annual average daily traffic (AADT) volume of more than 210,000 vehicles. About later, at an interchange with the western terminus of I-640, the northern bypass around downtown Knoxville, I-75 splits north off of I-40 and onto a concurrency with I-640. Along this concurrency, exits are numbered according to I-640 mileage. Heading north, the interstates come to an interchange with SR 62 (Western Avenue) about later.

On the way to Liberty the road passes through Cottage Grove and crosses the Indiana Eastern Railroad. In Liberty the highway has an all-way stop at SR 44, this intersection is the southern end of the SR 44 concurrency. In the center of Liberty the two road end the concurrency at a traffic light with SR 101, with US 27 heading north, SR 44 heading west and SR 101 heading south. US 27 leaves Liberty heading due north as a two-lane rural highway.

Snyder points out an O(N3) algorithm means that double the concurrency gives only about a 26% increase in problem size. Thus, while it may be possible to occupy vast concurrency, doing so may bring little advantage over the original, less concurrent solution—however in practice there have still been considerable improvements. Hill and Marty emphasize also that methods of speeding sequential execution are still needed, even for multicore machines. They point out that locally inefficient methods can be globally efficient when they reduce the sequential phase.

This is the highest isolation level. With a lock-based concurrency control DBMS implementation, serializability requires read and write locks (acquired on selected data) to be released at the end of the transaction. Also range-locks must be acquired when a SELECT query uses a ranged WHERE clause, especially to avoid the phantom reads phenomenon. When using non-lock based concurrency control, no locks are acquired; however, if the system detects a write collision among several concurrent transactions, only one of them is allowed to commit.

Fingerboard Road is likely named for a finger-shaped sign pointing toward a cannery in Monrovia, a sign that would have been at the highway's western intersection with MD 75. The MD 75 concurrency next to the fingerboard was the first segment of Fingerboard Road paved around 1921. MD 80's old concurrency with U.S. Route 240 (US 240, later MD 355) was paved as a concrete road in 1923. US 240 through Urbana was widened to by 1930 and resurfaced with bituminous concrete in 1938.

M-123 is a state trunkline highway in the eastern Upper Peninsula of the U.S. state of Michigan. It is one of only a few highways in Michigan that curve around and form a U-shape. In fact, M-123 has three intersections with only two state trunklines; it meets M-28 twice as a result of its U-shaped routing. M-123 also has a rare signed concurrency with a County-Designated Highway in Michigan; in Trout Lake, there is a concurrency with H-40.

Past this interchange, the road runs through neighborhoods, intersecting County Route 621 (Almonesson Road) and County Route 551. The latter forms a concurrency with Route 47 and these two routes run northeast through commercial areas as a four-lane undivided road, crossing the Big Timber Creek into Brooklawn, Camden County. Here, it comes to a traffic circle with U.S. Route 130 and County Route 753, where Route 47 ends and County Route 551 continues on to Camden, forming a brief concurrency with U.S. Route 130.

The concurrency of payment method with paying (the good/service has to be paid for as it is obtained), determines its pain. Payment methods that don't allow for this concurrency are decoupled, and as such the pain of paying for the good/service is postponed, whereas the pleasure from obtaining the good/service is immediately experienced. The decoupling theory focuses predominantly on the different behaviours associated with credit card usage. Credit cards being the only method that allows for non-concurrent payment at the point of sale.

The route's southern terminus is in downtown Cincinnati at the U.S. Route 27 (US 27)/US 52/US 127 concurrency, which is also the western terminus of US 22. SR 3 and US 22 share the same path for nearly , parting ways in the city of Washington Court House, where SR 3 is joined with US 62. This concurrency runs nearly to Columbus. From there SR 3 continues solo to Sunbury, where it joins US 36 for just over until it reaches Mount Vernon.

They rise onto the Cumberland Plateau and enters Monteagle as Dixie Highway. SR 2/US 41 has an intersection with becomes US 41A, SR 56, and SR 15, where SR 2/US 41 becomes concurrent with SR 56 as they enter town from the southwest as West Main Street. The concurrency continues east through downtown as West Main Street before becoming simply Main Street east of downtown. US 41 and SR 56 leave the concurrency and turn north as Fairmont Avenue before going northeast to Tracy City.

They travel south of Cox Lake and cross over the Tar River north of Montarella Lake, before crossing over Baker Creek into Talbot County. They travel to the north of Box Springs. The highways meet the northern terminus of SR 355\. Just before entering Geneva, SR 41 joins the concurrency. In Geneva, they meet the western terminus of SR 96, where SR 540 departs the concurrency on SR 96, and turn to the north. In Talbotton, they intersect SR 90/SR 208 (Clark Street).

After passing through Richford at CTH B, WIS 21 gradually curves northward to junction with CTH Y - where it turns sharply eastward and junctions with WIS 22 and WIS 73 north in Wautoma. WIS 21 follows WIS 73 south for two miles (3 km) before turning east again of the concurrency near Silver Lake. WIS 152 junctions with the routes about two miles (3 km) northwest of the eastern concurrency terminus. The highway passes through Lohrville and Redgranite and junctions with WIS 49 south of Auroraville.

The second, a overlap through western and central New York, is the second-longest concurrency in the state, stretching from Avon east to the city of Auburn in Cayuga County. The concurrency is known locally as "Routes 5 and 20". As the route proceeds across the state, it also directly or indirectly meets every major north–south highway in upstate New York, including all three north–south Interstate Highways (I-390 in Avon, I-81 in Syracuse via US 11, and I-87 in Albany).

The route was realigned between Wright City and US-70 in 1960, shifting SH-98 further west to begin its US-70 concurrency in Valliant. SH-98 was returned to a straighter alignment in 1975, eliminating the concurrency with US-70 and bypassing Valliant. The final major change to SH-98 occurred in 1982, when the road north of Wright City was removed from the highway system and SH-98 extended east toward Glover. This set the road at its present-day northern terminus.

WIS 82 turns east off the concurrency in downtown Viroqua at the junction with WIS 56 west. WIS 27 turns north off the concurrency with the U.S. Highways in Westby and crosses into Monroe County near Newry. The highway crosses WIS 33 in Cashton, Wisconsin and passes through Melvina before crossing I-90 just south of Sparta. In downtown Sparta, WIS 27 crosses WIS 16. The junction is also the west terminus of WIS 21 and the point where WIS 71 west joins WIS 27 heading north.

The highway has a grade crossing of the Green Mountain Railroad and crosses the Mill River during its brief concurrency with VT 155. East of VT 155, VT 140 enters the town of Mount Holly and reaches its eastern terminus at VT 103. The Vermont Agency of Transportation maintains the portions of VT 140 along the VT 133 concurrency and east of US 7. The towns of Poultney, Middletown Springs, Tinmouth, and Wallingford maintain the non-state-maintained portions of the highway within their borders.

The highway meets County Trunk Highway F (CTH-F), CTH-Q, and CTH-SS within Bloomer and runs concurrently with WIS 64 along the boundary between the towns of Woodmohr and Bloomer, just north of the city of Bloomer. The concurrency runs east for approximately before the highway runs north from it. Shortly after passing through the community of Island Lake, the highway runs along or near the Chippewa River. South of the village of Bruce, the highway follows a short westward concurrency with US 8.

State Route 745 (SR 745) is a state route in central Ohio that runs in a north-northwesterly direction along the west bank of the Scioto River. Its southern terminus is at the concurrency of U.S. Route 33 (US 33) and SR 161 in Dublin, and it runs for approximately to Concord Township in Delaware County, where it arrives at its northern terminus at the concurrency of US 42 and SR 257\. SR 745 was designated in 1937, and its routing has not changed since.

East St. Louis has five St. Louis MetroLink stations: East Riverfront, 5th & Missouri, Emerson Park, JJK Center, and Washington Park. Interstate 55, Interstate 64, Interstate 70, and U.S. Route 40 run through East St. Louis and are linked to St. Louis by the Poplar Street Bridge and Stan Musial Bridge. Prior to its decommissioning, the fabled U.S. Route 66 also shared a concurrency with these Interstate highways. In addition, U.S. Route 50 also shared a concurrency prior to its being rerouted to run concurrently with Interstate 255.

Illinois Route 49 (IL 49) is a north-south state highway in east-central Illinois. It runs from Willow Hill at IL 33 north to the beginning of the U.S. Route 45/52 concurrency near Ashkum.

The two highways head north into residential areas. The road leaves Jasper heading northeastward toward Loogootee. In Haysville, the concurrency with SR 56 ends. US 231 heads north-northeast from SR 54, before turning more northward.

Brent Hailpern is a computer scientist and manager at IBM Research. His research work focused on programming languages and concurrency, and he is now Director of Computer Science at IBM Research - Almaden in San Jose, California.

The commission authorized relocations of US-73 and K-20 in and around Everest through an August 12, 1964, resolution. The eastern end of K-20's concurrency with US-73 had been southeast of Everest.

Before the intersection of Calloway Drive, the Silver Comet Trail makes a sharp turn south. The eastern terminus of US 278 Bus./SR 6 Bus. is also the west end of the concurrency with SR 101\.

The total mileage in the table below is greater than that given by TxDOT, because the concurrency with US 281 is not included in its official description or mileage; however, the route is signed as concurrent.

The route leaves AR 34 and shoots northwest to Hooker, where it meets AR 141. After Hooker, the route straightens north, meeting AR 90 for a brief concurrency before terminating at US 62 east of Corning.

The southern part of the eastern segment south of Claxton had completed grading, but was not surfaced. By the middle of next year, the entire Tattnall County portion of the SR 144 concurrency was hard surfaced.

At this intersection, US 221 joins the concurrency. After a curve to the northwest, the four highways intersect East Park Avenue. Here, US 221/SR 31 split off to the northeast and then leaves the city.

It curves to the north-northeast and intersects US 12\. The two highways travel concurrently to the southeast. They curve to the northeast and cross over Claymore Creek. They intersect SD 1806, which joins the concurrency.

At this point, Route 17 forms a concurrency with I-287 and the road widens to six lanes as it passes between the Ramapo Valley County Reservation to the west and business parks to the east.

North Carolina Highway 27 (NC 27) is a primary state highway in the U.S. state of North Carolina. The route traverses through southern and central North Carolina, about of it as a concurrency with NC 24\.

The highways share a brief concurrency near the city's downtown district. : in Greensboro : east of Reidsville ;Virginia : on the Virginia state line at Danville. The highways travel concurrently through the city. : in Danville : south of Lynchburg.

Route 2 begins at the Kansas state line in Cass County. The first town is passes through is West Line, followed by Freeman. In Harrisonville it has a brief concurrency with Interstate 49/U.S. Route 71.

The three routes continue into Anadarko, where State Highway 8 briefly joins the concurrency. US-283 and SH-8 split off to the north, while US-62/SH-9 head out of town to the east.

An iterator over a set is created dynamically and is called a family of microthreads. This is the mechanism that allows the model to generate concurrency, which can be run on multiple processors or functional units.

In databases, and transaction processing (transaction management), snapshot isolation is a guarantee that all reads made in a transaction will see a consistent snapshot of the database (in practice it reads the last committed values that existed at the time it started), and the transaction itself will successfully commit only if no updates it has made conflict with any concurrent updates made since that snapshot. Snapshot isolation has been adopted by several major database management systems, such as InterBase, Firebird, Oracle, MySQL, PostgreSQL, SQL Anywhere, MongoDBMultiversion concurrency control in MongoDB, MongoDB CTO: How our new WiredTiger storage engine will earn its stripes and Microsoft SQL Server (2005 and later). The main reason for its adoption is that it allows better performance than serializability, yet still avoids most of the concurrency anomalies that serializability avoids (but not always all). In practice snapshot isolation is implemented within multiversion concurrency control (MVCC), where generational values of each data item (versions) are maintained: MVCC is a common way to increase concurrency and performance by generating a new version of a database object each time the object is written, and allowing transactions' read operations of several last relevant versions (of each object).

As the road continues north, it heads through a mix of homes and farmland with a few commercial areas. Route 47 enters inhabited areas again as it crosses into Glassboro. The road continues north and enters business areas before heading into neighborhoods and coming to an intersection with High Street, which runs east as U.S. Route 322/County Route 536 and west as County Route 641. Here, U.S. Route 322 and County Route 536 join Route 47 for a concurrency. The three routes head through commercial areas before U.S. Route 322 and County Route 536 turn to the west on West Street. Past this intersection, Route 47 continues north as a three-lane road with a center left-turn lane, passing more buildings. The route intersects County Route 553 and forms a concurrency with that route which lasts until County Route 553 turns north onto Woodbury Avenue. Along this concurrency, the road widens to five lanes as it passes a couple shopping centers. Past the concurrency, Route 47 runs north through suburban localities as a two-lane road, entering Washington Township at the crossing of Kressey Lake.

It crosses Lake Estelle on the Andrews Causeway before reaching the border between Orlando and Winter Park. In Seminole County, the redevelopment of the 17-92 Community Redevelopment Area is handled by the US 17-92 Community Redevelopment Agency, a component unit of the County government. In Sanford, Florida, US 17/US 92 shares a concurrency with westbound SR 46 beginning at Paola Road (CR 46A) and 25th Street. During this triple-concurrency, US 17/US 92/SR 46 intersects an at-grade railroad crossing with a freight line at the intersection of West 13th Street, also the western terminus of CR 415, and then a pair of railroad crossings at a junction of two other freight lines. The routes turn left at the intersection of First Street, and the wrong way concurrency between US 92 and SR 46 becomes more geographically accurate.

At Brownbranch, the highway enters another part of the Mark Twain National Forest, and at Bradleyville, it has a short concurrency with Route 125. At Kissee Mills, the road turns west with U.S. Route 160 and the two are united to Forsyth. At Forsyth, Route 76 leaves US 160 and crosses Bull Shoals Lake. At Branson, the road crosses Lake Taneycomo and meets U.S. Route 65. Route 76 runs concurrent with US 65 for before exiting onto the Ozark Mountain Highroad Freeway. While on the freeway, Route 76 has an interchange with Route 248. At the west end of the highroad, Route 76 returns to its original route at an incomplete interchange, connecting with Route 376. On the west side of Branson, a concurrency with Route 265 begins; at Branson West, a concurrency with Route 13 begins.

In downtown, the concurrency once again intersects I-24 and continues northeast, intersecting SR 58 (West 20th Street) two blocks later. US 64 and US 11 leave the concurrency here while US 41 and SR 17 leave the concurrency after five more blocks. US 72 terminates at this intersection (West Main Street) while US 76 begins and follows US 41/SR 17 southeast. SR 2, still Broad Street and unsigned, continues north for several more blocks and then turns southeast as East Martin Luther King Blvd, at the intersection with SR 316. SR 2 then intersects SR 8 (Market Street) immediately afterwards. SR 2 then becomes Bailey Avenue and once again becomes concurrent with SR 17 (South Willow Street) and then US 64/US 11 (Dodds Avenue) as SR 17 leaves and proceeds south with US 64/US 11.

Then, in 1939, SR 231 was extended to the north one more time, via a concurrency with SR 103 and SR 67 and then along a previously un-numbered roadway to its present northern terminus in Tiffin.

US 11W goes through Rutledge, Bean Station, Rogersville, and Kingsport. US 11E goes through Jefferson City, Morristown, Russellville, Greeneville, Jonesborough, Johnson City, where the route forms a concurrency with US 19, and Bristol, before crossing into Virginia.

HSQLDB version 2.0 has three transaction control modes. It supports with table level locks or with multiversion concurrency control (MVCC), or a combination of locks and MVCC. version 1.8.1 supports transaction isolation level 0 (read uncommitted) only.

After Highway 52 crosses the Mississippi River in downtown St. Paul, the route intersects Interstate 94 and follows I-94 to the North Dakota state line; U.S. 52 is not signed along the length of this concurrency.

US 701 has a length of in South Carolina and spans in North Carolina. The U.S. Highway is a part of the National Highway System for one short stretches during its concurrency with NC 24 in Clinton.

North of Gladewater, US 271 passes through Gilmer, where there are junctions with SH 300 and SH 154. There is also another concurrency (only 1.5 miles) with SH 155 which then veers to the northeast toward Linden.

It will stay concurrent with US-81 for , through the town of Okarche. Three miles after Okarche, SH-3 leaves US-81. This marks the first point that SH-3 has not been part of a concurrency.

Until 2007, US 331/SR 83 turned left at State Road 20 in Florida in a short concurrency until it reached Madison Street, then traveled north past Owl's Head Road just south of Eglin Air Force Base.

The northernmost segment was paved in 1987, completing the paving along the entire route. The H-58 concurrency was removed in 2004 when the northern segment of H-13 along Miners Castle Road was redesignated H-11.

This proposed scenic highway was never fully realized, and US 51 effectively followed the route of US 61 through the New Orleans area until being truncated to its present terminus in LaPlace in 1951, eliminating the concurrency.

Afterwards, crash recovery ignores incomplete entries. Although implementations vary depending on factors such as concurrency issues, the principle of atomicity – i.e. complete success or complete failure – remain. Ultimately, any application-level implementation relies on operating-system functionality.

An object can perform various actions at a particular time, but cannot have a concurrency within itself. Also an object class that isn't involved in any sort of relationship(component/specialization) is called an independent object class.

Near Gallatin, it turns east forming a concurrency with Route 6 for , then turns north again. A few miles north is an interchange with I-35. Then, Route 13 ends at US 69/US 136 in Bethany.

They begin a concurrency. Immediately, they cross over Boone Branch. Then, they split. Since KY 615 is a circular route, the two highways meet again in Morris. KY 213 curves to the northwest and enters Montgomery County.

In downtown Toccoa, SR 184 leaves the concurrency at the intersection of Currahee Street and Broad Street by turning north onto Broad Street while the other two routes stay on Currahee Street. This intersection is also the northern terminus of SR 63/SR 106, which head south on Broad Street. After passing under the Norfolk Southern Railway underpass, SR 184 turns right onto Tugalo Street forming a wrong-way concurrency with SR 17 Alternate. After about , SR 184 turns left onto Prather Bridge Road while SR 17 Alternate continues east on Tugalo Street.

Route 95 is a highway in southern Missouri. Its northern terminus is at Route 32 at Lynchburg in Laclede County. Its southern terminus is at U.S. Route 160 at Lutie about 2.5 miles west of the Theodosia arm of Bull Shoals Lake in Ozark County.Ava, Missouri, 30x60 Minute Topographic Quadrangle, USGS, 1985 Wrong way concurrency sign on Missouri routes 5 and 95 at Wasola, Missouri A short section forms a wrong-way concurrency with Route 5; Route 95 is marked as "North Route 95" but goes south at this location.

Pennsylvania Route 239 (PA 239) is a state highway located in Luzerne, Columbia and Lycoming Counties in Pennsylvania. The southern terminus is at PA 93 in Nescopeck Township. The northern terminus is at PA 42 in North Mountain. The route heads north from PA 93 and parallels the Susquehanna River between Wapwallopen and Mocanaqua before crossing the river into Shickshinny and forming a concurrency with U.S. Route 11 (US 11). Past Shickshinny, PA 239 runs west through rural areas to Benton, where it has a concurrency with PA 487\.

Photo of the former PA 244/PA 449 concurrency in Genesee Township Most of PA 244's route was paved in 1931 and was signed by 1941. Originally, PA 244 ended at PA 449 in Genesee, but by 1982 it was extended east across the Genesee River to the New York state line. In 2003, the School Street Bridge carrying PA 244 across the Genesee River was closed due to its age and deteriorating conditions. This closure forced PA 244 to share a short concurrency with PA 449 and SR 1010 in Genesee.

Route 10 crosses the border from Granby, Connecticut into Southwick, Massachusetts, overlapped with U.S. 202. It runs north through the Pioneer Valley towns of Southwick, Westfield, Southampton, Easthampton, Northampton, Hatfield, Whately, Deerfield, Greenfield, Bernardston, Gill, and Northfield. Route 10 has a long concurrency with U.S. 5 for about from Northampton to Bernardston, where it was sometimes called the "5 & 10 Highway". During this concurrency, it closely parallels Interstate 91, with five exits from Northampton to Deerfield, with close access at Route 2 in Greenfield and another exit, solely for Route 10, in Bernardston.

The road curves east-southeast and heads into the residential community of Pleasant Unity, coming to an intersection with PA 981. Here, PA 981 turns east to form a concurrency with PA 130, with the road heading southeast through more of the community. PA 981 splits to the northeast and PA 130 continues southeast into open agricultural areas with some woods and homes. The road becomes the border between Unity Township to the northeast and Mount Pleasant Township to the southwest as it forms a short concurrency with PA 982 in Lycippus.

View east along US 460 Bus. at SR 131 and SR 1012 in Appomattox U.S. Route 460 Business (US 460 Business) is a business route of Appomattox, Virginia. The road is named Confederate Boulevard and begins at a diamond interchange along US 460 with the southern terminus of State Route 26, and the east end of the concurrency with US 460 and State Route 24. The concurrency with SR 24 ends shortly after this interchange and makes a left turn onto Old Courthouse Road as it heads for Mt. Rush, Virginia.

ND 13's concurrency with ND 1 continues southward for four miles, then ND 1 continues to head south toward Oakes, while ND 13 forks to the east and travels to Gwinner, entering Sargent County in the process. Just east of Gwinner, ND 13 is concurrent with ND 32 for a mile east. ND 13 travels eight miles east of this concurrency, then a mile north and about a mile and a half northeast to reach the southeast corner of Milnor. ND 13 then travels east to the Richland county line.

First Highway 269 reassurance marker north of the US 64 concurrency The highway begins at US 49 in eastern Woodruff County within the Arkansas Delta between Hillemann and Bemis. The route begins due west to an intersection with the southern terminus of Highway 145 before turning due north and running as a section line road through a rural, agricultural area. Highway 269 crosses the Union Pacific Railroad tracks before meeting US 64. These two routes form a concurrency west for until Highway 269 turns north toward Pumpkin Bend.

The four-highway concurrency curves slightly to the east-southeast to an interchange with US 25/SR 121 (Peach Orchard Road), which both join the concurrency. The six highways travel to the east-northeast and intersect the northern terminus of Doug Barnard Parkway (former SR 56 Spur) and the southern terminus of Molly Pond Road. The highways curve to the north-northeast and intersect Laney Walker Boulevard, thus effectively entering downtown. They travel just to the northwest of Magnolia Cemetery, Cedar Grove Cemetery, and May Park and southeast of James Brown Arena.

Briefly after this intersection, Howard Avenue widens from two lanes to four lanes with a center turn lane. Approaching Western Boulevard, the road runs through a commercial district of the city with several shopping centers alongside the road. The road intersects US 64 Alternate (US 64 Alt.) at Western Boulevard and turns south along a concurrency with the two lane road. NC 122 once again intersects NC 111 at Wilson Street along the southern side of Tarboro, beginning another concurrency with the road as NC 111 turns to Western Boulevard.

Some languages are designed for sequential parallelism instead (especially using GPUs), without requiring concurrency or threads (Ateji PX, CUDA). A few interpreted programming languages have implementations (e.g., Ruby MRI for Ruby, CPython for Python) which support threading and concurrency but not parallel execution of threads, due to a global interpreter lock (GIL). The GIL is a mutual exclusion lock held by the interpreter that can prevent the interpreter from simultaneously interpreting the applications code on two or more threads at once, which effectively limits the parallelism on multiple core systems.

The four-highway concurrency curves slightly to the east-southeast to an interchange with US 25/SR 121 (Peach Orchard Road), which both join the concurrency. The six highways travel to the east-northeast and intersect the northern terminus of former SR 56 Spur (Doug Barnard Parkway) and the southern terminus of Molly Pond Road. The highways curve to the north-northeast and intersect Laney Walker Boulevard, thus effectively entering downtown. They pass just to the northwest of Magnolia Cemetery, Cedar Grove Cemetery, and May Park and southeast of James Brown Arena.

I-44 begins near exit 1 in Wichita Falls concurrent with US 277, US 281 and US 287. US 281 and US 287 continue to the south while US 277 leaves the concurrency at exit 1, which also provides access to US 82. I-44 heads north through Wichita Falls to an interchange with US 287 and Spur 325. US 287 leaves the concurrency as a freeway to the west while Spur 325 leaves the interchange towards the northeast providing access to Sheppard Air Force Base and Wichita Falls Municipal Airport.

Minor rural intersections with Highway 321S, Highway 38, and Highway 267 are also south of Beebe. Once the route enters Beebe a concurrency forms with US 67B as Main Street, an officially designated exception. US 67B/AR 31 passes NRPHP-listed properties Beebe Theater, Staggs-Huffaker Building, Powell Clothing Store, Laws-Jarvis House, and the Smith-Moore House as a narrow two-lane undivided road through Beebe. In north Beebe the concurrency ends at a junction with US 64/US 67/US 167 (Future Interstate 57), a fully controlled-access highway.

The growing Northwest Arkansas area and the University of Arkansas needed an Interstate connection to Little Rock, and through traffic north to Kansas City had also outgrown the winding US 71 north from I-40. The route was extended north to Mountainburg in the late 1990s on an all-new alignment (going under concurrency with I-40, one of the only auxiliary routes with a concurrency with its parent) with the route being completed to Bella Vista in January 1999. However, the segment north of I-40 became a part of Interstate 49 in 2014.

After passing through the settlement of West Franklin, the road enters the town center of Franklin where SR 200 joins SR 182 for a concurrency. Through this concurrency, the road passes numerous houses, churches, and small businesses. Past the point where SR 200 heads towards the southeast, SR 182 heads northeast, first crossing the Down East Sunrise Trail (formerly the Calais Branch railroad) then passes the town's post office, a cemetery, a club, and additional houses. The road starts to curve to the east entering the unorganized territory of East Hancock.

SR 86 was further extended through Tucson and the Tohono O'odham Indian Reservation to Ajo in 1943. SR 85 was extended south from Ajo to Lukeville in 1955, establishing a concurrency with SR 86 to Why. In 1970, SR 86 had its eastern end truncated to US 89 (later State Business Route 19) in Tucson after being replaced by I-10 between Tucson and New Mexico. In 1991, the concurrency with SR 85 between Ajo and Why was removed, truncating the western end of SR 86 to Why.

State Route 186 (SR 186) is a north-south state highway in the northwestern part of the U.S. state of Ohio. Traveling through mostly rural areas, State Route 186 has its southern terminus at a T-intersection with the U.S. Route 224/State Route 15 concurrency nearly south-southeast of McComb. Following a long concurrency with State Route 235 into McComb, State Route 186 arrives at its northern terminus at its junction with State Route 613. North of State Route 613, State Route 235 carries on as a solo route.

Though US 63 as a stand-alone highway had always ended at Turrell, Arkansas before the 1999 extension, in the past it was concurrent with US 61/US 64/US 70/US 79 (and later I-55) on into Memphis, Tennessee, over the Memphis & Arkansas Bridge. Unlike the 1999 extension, this concurrency to Memphis was generally in line with the rest of US 63\. Though some maps continued to show this concurrency until 1999, Arkansas had not recognized US 63 south of Turrell for many years, since at least the 1960s.

Agricultural scene west of Cofield NC 461 is a two-lane rural highway that begins at NC 561 in Saint John, and travels northeast, crossing NC 11 and having a concurrency with U.S. Route 13 (US 13). Following its split from US 13, it travels to NC 45 in Winton. From Winton, and in concurrency with NC 45, it travels through Cofield, then splits just east of the village. It continues north on Farmers Chemical Road, then east on River Road, ending at the entrance of Nucor Plate Mill, Hertford.

By June 1963, SR 15 was shifted to its current concurrency with US 1/US 23/SR 4 between Florida and Racepond and on US 1/SR 4 from Baxley to South Thompson. SR 121 was extended south-southeast along US 1/US 23/SR 4 (and SR 15) from Racepond to Folkston. By 1966, SR 88 was extended to the Sandersville area, thereby traveling on a concurrency with US 1/US 221/SR 4 and SR 17 in Wrens. The 1966 GDOT map was the first one with an inset map of Waycross.

SH-15 just east of I-35 The eastern SH-15 picks up a US-64/412 south of Garber, and begins concurrent with State Highway 74 heading northbound. It splits from SH-74 to head through Billings and has an interchange with Interstate 35 at milemarker 203. It then has a five-mile (8.0 km) concurrency with U.S. Highway 77. After leaving US-77, it passes through Red Rock, and has a concurrency with US-177, and splits off just north of the intersection with the Cimarron Turnpike.

SR 183 begins at its intersection with US 80 in Uniontown. From this point, the route travels in a northerly direction through Uniontown before taking a more northeasterly course en route to Marion. At Marion, SR 183 begins an approximately concurrency with SR 5 through the town and then begins another approximately concurrency SR 14 at the eastern end of Marion through Sprott. From Sprott, SR 183 continues on its northeasterly course through the Talladega National Forest en route to its northern terminus at US 82 in Chilton County.

State Road 166 begins as Jefferson Street at the southeastern terminus of the US 90/SR 73 concurrency, taking a secret concurrency with County Road 167 from SR 73. Two blocks north at Clinton Street the road runs between the city fire department and the First Presbyterian Church. At Davis Street, the route leaves the Marianna Historic District. Just north of there, the road begins to curve just to the northeast as it officially leaves the city at the intersection of Kelson Avenue, one side of which leads to Chipola College.

A portion of the highway southwest of Alma was indicated to be projected mileage. A year later, the entire central segment south of Surrency, as well as the entire portion north of the SR 144 concurrency, was hard surfaced. By the middle of 1957, the entire SR 168 concurrency, a small portion north of the Clinch–Atkinson county line, and nearly the entire Bacon County portion of the Pearson–Alma segment, were hard surfaced. SR 250 was relocated to the northwest, replacing the entire eastern segment of SR 64.

At the unincorporated community of Jeff, the highway re-enters Calhoun County. Southwest of there, in Edison, is a brief concurrency with SR 216\. It heads east and curves to the southeast to enter Morgan, where it has a short concurrency with SR 45\. Continuing to the southeast, it crosses over Ichawaynochaway Creek, then passes McClendon Lake and enters Leary. In the city is an intersection with SR 55 and SR 62 (Mercer Avenue). At this intersection, SR 62 travels concurrent with SR 37 until it splits off onto Albany Highway.

Interstate 90 Business is a business loop of Interstate 90 in Murdo. It runs from a diamond interchange at exit 191, then follows Fifth Avenue (South Dakota Highway 248), passing by sites such as the Pioneer Auto Museum.Pioneer Auto Show/Museum (Location map) At a blinker-light intersection with Kennedy Avenue, BL 90 leave its concurrency with SD 248 and turns south and turns south onto Willow Street before ending at another diamond interchange with exit 192 on I-90, which is also shared with the western terminus of a concurrency with U.S. Route 83.

NC 37 was established in 1934 as a renumbering of NC 321 from US 17 in Winfall to SR 53 at the Virginia state line. In 1940, NC 37 was extended south in concurrency with US 17 into Chowan County, where it then replaced a segment of NC 172 to NC 32 in St. Johns. In 1952, NC 37 was truncated at US 13, from the Virginia state line. In March 1987, NC 37 was rerouted onto new bypass route, in concurrency with US 17, east of Hertford.

The road starts curving more toward the north and somewhere off to the east is the beginning of Georgia State Route 31 Connector. North of there, it enters the Lakeland City Limits just south of Burnt Church Road, becoming South Valdosta Road. After passing the city department of public works garage it is joined by a concurrency with Georgia State Route 135. South Valdosta Road comes to an end, but US 221/SRs 31/135 turn right at a wrong-way concurrency with U.S. Route 129, which also has concurrencies with SRs 11/37/122.

The highway begins at its intersection with Wisconsin Highway 58 north of the community of Neptune and follows an northeasterly path from it. After a short concurrency with County Highway G, it passes through Hill Point and continues east until it reaches Loganville. In Loganville, the highway becomes concurrent with Highway 23 and heads northwards. After 3.5 miles, the concurrency ends and the highway heads eastwards, passing through Wiedman Memorial Park and intersections with county highways CH and D before terminating in Rock Springs at its intersection with Highway 136 and County Highway DD.

Northern terminus of US 259 in the Ouachita Mountains After crossing into McCurtain County, Oklahoma, US-259 immediately meets up with State Highway 87, and continues north through Harris. Maps indicate that US-259 and SH-87 overlap to Idabel, but officially, this is not the case, and ODOT signage does not reflect a concurrency. US-259 bypasses Idabel to the south and east, concurring with U.S. Highway 70 Bypass. East of Idabel, the bypass route ends, and US-259 begins a concurrency with mainline US-70 and SH-3.

Rich Hickey developed Clojure because he wanted a modern Lisp for functional programming, symbiotic with the established Java platform, and designed for concurrency. Clojure's approach to state is characterized by the concept of identities, which are represented as a series of immutable states over time. Since states are immutable values, any number of workers can operate on them in parallel, and concurrency becomes a question of managing changes from one state to another. For this purpose, Clojure provides several mutable reference types, each having well-defined semantics for the transition between states.

Leaving National Route 286 and central Sendai, a section of the highway, the Sendai Nishi Road is a limited-access road that connects central Sendai to the cross-country Tōhoku Expressway via of tunnels. Continuing west from the junction with the Tōhoku Expressway, the highway continues as the Ayashi Bypass. The highway meets National Route 457, which is shares a brief concurrency with before that route continues to the south. Crossing into Yamagata Prefecture the highway shares a significant concurrency with National Route 13 in the Yamagata cities of Tendō and Yamagata.

After a brief concurrency with US 183 north, it turns east and briefly overlaps Nebraska Highway 137 before continuing eastward to another concurrency with Nebraska Highway 11 in Butte. It goes south out of Butte, then turns east and meets U.S. Highway 281 in Spencer, which it also overlaps. It continues eastward through the tribal lands of the Ponca Tribe of Nebraska and around the edge of Niobrara State Park. It then crosses the Niobrara River and enters the village of Niobrara, Nebraska, where it meets Nebraska Highway 14.

The highway then enters the city of Enid, running along Van Buren Street. At its intersection with Owen K. Garriott Road, US-81 also intersects US-60 and US-412. While US-412 continues straight through the intersection, US-60 forms a concurrency with US-81. The two highways continue north, then curve northeast and begin following North 4th Street, which carries US-64, creating a three-route concurrency. US-60/US-64/US-81 head due north through the northern reaches of Enid, serving as the eastern terminus of SH-45.

Highway 115 begins at US 167/AR 58 (Main Street) in the small town of Cave City. The highway runs eastward in a concurrency with Highway 58 through the sparsely populated forest and pastures of the Central Plateu subregion of the Ozark Highlands. Highway 58 turns left, ending the concurrency at the unincorporated community of Emery, with Highway 115 continuing east through rural areas and unincorporated communities Ben-Gay and Calamine to enter Lawrence County. Entering the western side of the county, Highway 115 has an intersection with Highway 117 north of Jessup.

There, the concurrency with SR 9 ends and US 19 is briefly concurrent with I-285, for about . US 19 leaves I-285 to travel through the northern suburbs of Atlanta along SR 400\. Most of this section is a limited-access road with four lanes in each direction, becoming two lanes in each direction as the highway continues away from the northern suburbs of Atlanta. It arrives in Dahlonega, where it is no longer concurrent with SR 400, before about of extremely curvy road, which includes a concurrency with US 129\.

The Lock Manager maintains an in-memory table that manages the database objects and locks, if any, on them along with other metadata about the lock. Access to any shared object is mediated by the lock manager, which either grants access to the resource or blocks it. SQL Server also provides the optimistic concurrency control mechanism, which is similar to the multiversion concurrency control used in other databases. The mechanism allows a new version of a row to be created whenever the row is updated, as opposed to overwriting the row, i.e.

Less than later, the route crosses into Candler County. Shortly after the county line, it has an interchange with Interstate 16 (I-16; James L. Gillis Memorial Highway). Just after the interchange, the route passes through the unincorporated community of Aline, before entering Tattnall County. In Cobbtown, it begins a concurrency with SR 23/SR 121\. In the central part of town, it meets the eastern terminus of SR 152 (New Cobbtown Road). The concurrency heads south-southeast and curves to the south-southwest into Collins, There they meet SR 292 (Manassas Street).

In 2012, Nebraska Department of Roads (NDOR) calculated as many as 2,410 vehicles traveling on the N-71/N-88 concurrency, and as few as 315 vehicles traveling east of the Banner–Morrill county line. This is expressed in terms of annual average daily traffic (AADT), a measure of traffic volume for any average day of the year. Only the N-71/N-88 concurrency is part of the National Highway System (NHS), a network of highways identified as being most important for the economy, mobility and defense of the nation.

In other words, a collection of serializable components provides overall system serializability, which is usually incorrect. A need in correctness across databases in multidatabase systems makes global serializability a major goal for global concurrency control (or modular concurrency control). With the proliferation of the Internet, Cloud computing, Grid computing, and small, portable, powerful computing devices (e.g., smartphones), as well as increase in systems management sophistication, the need for atomic distributed transactions and thus effective global serializability techniques, to ensure correctness in and among distributed transactional applications, seems to increase.

Achieving global serializability effectively over different types of concurrency control has been open for several years. Commitment ordering (or Commit ordering; CO), a serializability technique publicly introduced in 1991 by Yoav Raz from Digital Equipment Corporation (DEC), provides an effective general solution for global (conflict) serializability across any collection of database systems and other transactional objects, with possibly different concurrency control mechanisms. CO does not need the distribution of conflict information, but rather utilizes the already needed (unmodified) atomic commitment protocol messages without any further communication between databases. It also allows optimistic (non-blocking) implementations.

In concurrency with SC 291, it reaches Wade Hampton Boulevard; leaving behind a business loop through downtown Greenville. In 1959, Interstate 85 was assigned from Spartanburg to North Carolina, in concurrency with US 29, once the highway was expanded into four- lanes. In 1962, US 29 was removed from Interstate 85 from Spartanburg to North Carolina and was moved back on its original routing, replacing US 29 Alternate. In the Greenville area, US 29 was rerouted back through Greenville along Interstate 185, which connected directly via Church Street, to Wade Hampton Boulevard.

It then engages with a much shorter concurrency with US 90 (much shorter than its concurrency with US 31). The route continues south to Foley, which is home to its notable junction with the Foley Beach Express access road and its other notable junction with US 98. After passing by The Park at OWA and a Lambert's Cafe, the route makes a short journey south to the Pelican Place at Craft Farms. Just past that point, the route makes a slight curve and The Track Family Fun Center comes into play, a small entertainment complex.

Southeast of Bogart, the two routes intersect US 78/SR 10, which come in from the southwest. At the intersection, SR 10 continues to the northeast, concurrent with US 78 BUS, while the US 78 mainline joins the US 29/SR 316 concurrency. US 29/US 78/SR 316 intersect SR 10 Loop/SR 422 (Paul Broun Parkway/Athens Perimeter Highway) southwest of Athens. Here, SR 316 has its eastern terminus, while US 29/US 78 join SR 10 Loop/SR 422 in a concurrency to the east.

North of Crowley, LA 13 crosses a bridge over Bayou Plaquemine Brule and narrows to an undivided two- lane highway. It then curves due north at LA 1121 (Oro Trail Road). later, LA 13 passes through Maxie and has a very short concurrency with LA 98, connecting to Iota and Roberts Cove. Over the next , LA 13 intersects several more rural highways following section line roads. These include LA 365, with which it has another concurrency, as well as LA 368 at Mowata and LA 370 at Bates.

Thus CO (with its variants) is the only general technique that does not require the typically costly distribution of local concurrency control information (e.g., local precedence relations, locks, timestamps, or tickets). It generalizes the popular strong strict two-phase locking (SS2PL) property, which in conjunction with the two-phase commit protocol (2PC) is the de facto standard to achieve global serializability across (SS2PL based) database systems. As a result, CO compliant database systems (with any, different concurrency control types) can transparently join such SS2PL based solutions for global serializability.

Interstate 393 begins at I-93's exit 15 interchange, where US 4 East leaves its concurrency with I-93 South and the I-393/US 4/US 202 concurrency begins. The four-lane freeway actually begins a short distance west of I-93 at the north end of Concord's Main Street where US 202 turns east from US 3. From there the road then intersects Commercial Street just before the exit 15 interchange. Just east of the exit 15 cloverleaf is I-393's exit 1 to Fort Eddy Road.

US 1 is concurrent with I-95 in two sections, both of which are river crossings. The western concurrency is between exits 68 and 70 from Old Saybrook to Lyme, where the two routes cross the Connecticut River via the Raymond E. Baldwin Bridge. The eastern concurrency is between exits 83 and 85 from New London to Groton, where the routes cross the Thames River via the Gold Star Memorial Bridge. Route 1's two other major bridge crossings closely parallel the I-95 crossings of those rivers.

After crossing the Delaware River, the route ends its concurrency with NY 30, and NY 28 continues northwest through Andes as Main Street and Delaware Avenue. In the village of Delhi, the highway becomes known as Andes Road and has a short concurrency with NY 10 in the village center. North of Delhi, it continues north towards the hamlet of Meredith, proceeding west past the hamlet. In Franklin, NY 28 makes a 90-degree turn to the north at the roundabout intersection with the eastern end of NY 357.

In 1992, SR 154 was rerouted on a concurrency with SR 166, from just west of the Chattahoochee River to the interchange with US 29, as it does today. In 2007, SR 70 was partially rerouted from the east side of the Chattahoochee River to follow the SR 92/SR 154/SR 166 concurrency on the west side of the river and cross back over west of Atlanta. It wasn't until the 2015-2016 edition of GDOT's state map that the section from I-75/I-85 to Lakewood Avenue was returned to the map.

After the intersection with SR 613 the road crosses a Norfolk Southern Railroad track and makes a sharp turn due east. The highway heads east, before another sharp curve due north.

If a system identifies end-users by some form of log-in procedure then a concurrency goal is highly desirable. By definition this is the largest number of concurrent system users that the system is expected to support at any given moment. The work-flow of a scripted transaction may impact true concurrency especially if the iterative part contains the log-in and log-out activity. If the system has no concept of end- users, then performance goal is likely to be based on a maximum throughput or transaction rate.

The SR 83 portion of the byway begins at the southwestern city limits of Monticello and travels to the northeast. It makes its way into downtown, where it intersects SR 11/SR 16/SR 212 at the southwestern corner of the town's square. The four routes are concurrent for one block (the southeastern corner of the square), where SR 11's southern lanes depart the concurrency. However, since the square is a one-way road, SR 11's northern lanes continue the concurrency to the northeastern corner of the square.
