Paradigms and Programming Models in Parallel Computing

In this paper parallel paradigms and programming models are presented and systematized. The fundamental approaches for parallel application decomposition are formulated and systematized as well. Parallel applications are classified according to the timing structure of the problem being solved. The parallel programming models are categorized in respect to the type of the parallelism utilized. The strategies for parallel application development are presented.
