AIn computer software, a '''parallel programming model''' is a concept that enables themodel expressionfor ofwriting [[parallel program]]s which can be compiled and executed. The value of a programming model is usually judged on its generality: how well a range of different problems can be expressed and how well they execute on a range of different architectures. The implementation of a programming model can take several forms such as libraries invoked from traditional [[sequential programming|sequential]] languages, language extensions, or complete new execution models.
 
Consensus on a particular programming model is important as it enables software expressed within it to be transportable between different architectures. The [[von Neumann model]] has facilitated this with sequential architectures as it provides an efficient ''bridge'' between hardware and software, meaning that high-level languages can be efficiently compiled to it and it can be efficiently implemented in hardware.<ref name="Valiant1990">Leslie G.
