A '''parallel programming model''' is a set of software technologies to express [[parallel algorithmsalgorithm]]s and match applications with the underlying parallel systems. It encloses the areas of applications[[application]]s, languages[[programming language]]s, compilers[[compiler]]s, [[library (computer science)|libraries]], communication[[communications systemssystem]]s, and [[parallel I/O]]. People have to choose a proper parallel programming model or a form of mixture of them to develop their parallel applications on a particular platform.

Parallel models are implemented in several ways: as libraries invoked from traditional sequential languages, as language extensions, or complete new execution models. They are also roughly categoried for two kinds of systems: shared-memory system and distributed-memory system, though the lines between them are largely blured nowadays.

A program[[programming model]] is usually judged by its expressibility and simplicity, which are by all meanings conflicting factors. The ultimate goal is to improve productivity of programming.
