In the thread pool pattern in programming, a number of N threads are created to perform a number of M tasks, usually organized in a queue. Typically, N << M. As soon as a thread completes its task, it will request the next task from the queue until all tasks have been completed. The thread can then terminate, or sleep until there are new tasks available. Computer programming (often simply programming) is the craft of implementing one or more interrelated abstract algorithms using a particular programming language to produce a concrete computer program. ... A thread in computer science is short for a thread of execution. ... In providing services to people, and in computer science, transport and operations research a queue is a First-In-First-Out (FIFO) process — the first element in the queue will be the first one out. ... The feasible regions of linear programming are defined by a set of inequalities. ...
The number of threads used (N) is a parameter that can be tuned to provide the best performance.
The advantage of using a Thread Pool over creating a new thread for each task, is that thread creation and destruction overhead is negated, which may result in better performance and better system stability. A task is an execution path through address space. In other words, a set of program instructions that is loaded in memory. ... In computing, optimization is the process of modifying a system to improve its efficiency. ... The word stability has a number of technical meanings, all related to the common meaning of the word. ...
When implementing this pattern, the programmer should ensure thread-safety of the queue. Thread-safety is a computer programming concept applicable to multi-threaded programs. ...
