摘要： MPICH是国内常用的集群计算消息传递系统。MPICH库函数提供的集群通信函数对并行程序的性能有很大的影响。根据集群通信的功能特性,初步地分析了MPICH集群通信的实现机制,并在Windows-10M NOWs和Linux-100M NOWs中测试了MPICH库函数提供的常用的集群通信函数的执行效率。

Abstract: MPICH is the most popular free message passing system for cluster. The parallel program is deeply depended on the collective communication functions in MPICH library. Based the characteristics of collective functions, this paper explores the implementing mechanism initially, and tests the performance of MPICH collective functions on the NOWs of Windws-10M and Linux-100M respectively.
