CPUs are produced with several cores today and every next CPU generation will feature even more cores, resulting in a requirement for concurrency not previously demanded. The framework is CSP\-presented as a scientific workflow model, specialized for scientific computing application. The purpose of the framework is to enable scientists to gain access to large parallel computation resources, which have been off limits because of the difficulty of concurrent programming using threads and locks.
