- Fork–join_model abstract "In parallel computing, the fork–join model is a way of setting up and executing parallel programs, such that execution branches off in parallel at designated points in the program, to "join" (merge) at a subsequent point and resume sequential execution. Parallel sections may fork recursively until a certain task granularity is reached. Fork–join can be considered a parallel version of the divide and conquer paradigm. The model was formulated as early as 1963.In pseudocode, a generic fork–join computation can be expressed as follows:solve(problem): if problem is small enough: solve problem directly (sequential algorithm) else: for part in subdivide(problem) fork subtask to solve part join all subtasks spawned in previous loop combine results from subtasksImplementations of the fork–join model will typically fork tasks, not actual threads or processes, and use a thread pool to execute these tasks; the reason for this design is that creating new threads tends to result in avoidable overheads. For example, general-purpose thread schedulers must deal with blocking for locks, but in the fork–join paradigm, threads only block at the join barrier.Fork–join is the main model of parallel execution in the OpenMP framework; it is supported in the Cilk programming language, by the Java concurrency framework, and by the Task Parallel Library for .NET.".
