并行计算模型对比分析

随着集群式系统的发展,并行计算模型在估计和评价系统的性能、引导集群的体系结构以及指导并行算法和程序的设计等方面都显得越来越重要。对于目前已有的并行计算模型的设计思想和原理的了解和分析,非常有利于新的模型的设计与研究。本文首先介绍了目前比较常见的5种并行计算模型,接着在同步性、通信方式和参数等3个方面分析比较了它们的异同和优缺点,最后得出结论,指出了下一代并行计算模型的发展趋势是与具体应用相关的并行计算模型。

Contrastive Analysis of Parallel Computation Model

With the rapid development of the clusters,parallel computation model is more and more importance on the design of the parallel algorithms and the parallel program.It is quite beneficial for the further study of new parallel model to understand and analyze the designing concept and rationale of the existing ones.This paper introduces five parallel computation models which are well known to the people firstly.Then,the difference of the style of synchroniza- tion and communication is compared in this paper.Finally,it is concluded that the next generation of parallel computa- tion model may be relative with the actual computation pattern.
