摘要: 大规模并行处理的发展要求并行应用程序具有良好的可扩展性.以二维电磁等离子体粒子云并行程序为例,描述了近优可扩展性分析的应用.在已知小规模系统性能的基础上,通过近优可扩展性分析,可以得到更大规模的系统在多少台处理机上运行更为"合理"的信息.

Abstract: With the development of massively parallel processing, it is necessary that the parallel applications would be capable of good scalability. It is described how to use the near optimal scalability analysis method with the two dimensional electromagnetic plasma parallel program using particle in cell method as an example. Having known the performance of small parallel systems, one can obtain the information about how many processors which the larger systems are running on can obtain the more"reasonable" performance when using the near optimal scalability analysis. A suit of practical scalability evaluation method is also proposed to find the reason why the practical scalability is bad, and help to optimize the application programs.

Key words: scalability, plasma, particle in cell method
