摘要
一、引言并行计算,或者并行处理,指的是这样一种努力和相关的研究:利用多个具有计算能力的部件来共同完成一个计算工作,以获得比用一个部件来完成要快的效果。这显然是一个很自然的想法。历史地看,几乎是自从有了计算机,就有了并行处理的想法和实践。在80年代后期到90年代初期。
From the perspective of application developers, comparing a few programming styles o example, this article describes the concept and programming models of data parallel computing, a as ideas and implications of runtime support. Data parallel computing is referred to such a class of a] cation of computing process: the same or similar operations are performed on each elements of the a cation data set. The main and the most natural programming model is SPMD (Single Program Multiple Data) for this kind of application on distributed memory systems. And SPMD programming model needs runtime support in order to obtain a good trade-off between execution efficiency and ease of programming.
