Since its appearance, pull-based development has gained popularity within the open software development community. On GitHub, over 400,000 pull-requests emerged per month on average in 2015. [1] It is also the model shared on most collaborative coding platforms, like Bitbucket, Gitorious, etc. More and more functionalities are added to ...
Implementations of the fork–join model will typically fork tasks, fibers or lightweight threads, not operating-system-level "heavyweight" threads or processes, and use a thread pool to execute these tasks: the fork primitive allows the programmer to specify potential parallelism, which the implementation then maps onto actual parallel execution.

Behavioral state machines can be used to model the behavior of individual entities (e.g., class instances), a subsystem, a package, or even an entire system. Protocol state machines are used to express usage protocols and can be used to specify the legal usage scenarios of classifiers, interfaces, and ports.
Using this model, access control requirements can be integrated with the rest of the system from the outset, because: a single notation is used to express both access control and functional requirements; a systematic and incremental approach to constructing a formal behavior tree specification can be adopted; and the specification can be ...
Illustration of the dining philosophers problem. Each philosopher has a bowl of spaghetti and can reach two of the forks. In computer science, the dining philosophers problem is an example problem often used in concurrent algorithm design to illustrate synchronization issues and techniques for resolving them.

A generalization of the fork-join queueing system is the (,) fork-join system where the job exits the system when any out of tasks are served. The traditional fork-join queueing system is a special case of the (,) system when =. Bounds on the mean response time of this generalized system were found by Joshi, Liu and Soljanin.
