Implementation and usage of a thread pool based on posix threads. http://www.hlnum.org/english/projects/tools/threadpool/doc.html

When working on a shared memory system the thread model is an easy and efficient way to change existing serial programs to make use of more than one processor. A widely used interface to threads are POSIX threads. Unfortunately, the interface is sometimes too difficult to use, especially for beginners. Therefore a wrapper is introduced which implements a pool of threads, where a job can be send to and is executed in parallel. This article describes the implementation and usage of this thread pool.
