摘要: 在共享和分布式存储两种并行计算环境下,组织了二维等离子体模拟粒子云网格法程序(2DCIC)的并行计算。首先,通过分析串行算法和2DCIC程序的单机执行特征,设计了并行算法和实现策略;然后,基于共享存储和消息传递两种并行程序设计方式,在四种共享和分布式存储并行机上,组织了具体的并行计算,对性能结果进行了详细的比较分析,获得了若干重要结论。

Abstract: It provides an overview of the parallel computing for 2-dimensional plasma simulations with particle clouds in cells methods under both shared-memory and distrbuted-memory parallel computing environments.The parallel algorithm and its implementation are desigened on the basis of the serial algorithm and the executing characteristics of the serial code.The practical parallel computations are performed under Challenge,DAWN 1000+, Power PC Cluster and XMZY. Many important conclusions are given and quite useful for the parallel computations of both types of particle simulation methods and other applicational codes.

Key words: particle clouds in cells methods, parallel computing, performance analysis, shared memory, message passing
