摘　　要：阐述在PC集群中运用消息传递接口MPICH(MessagePassingInterfaceandChameleon)进行并行程序设计的基本方法 ,并以计算圆周率π值的并行算法程序为例 ,介绍了MPICH中基本例程的功能和调用方法。并行程序设计的关键技术是如何处理好各个进程之间的通信问题 ,MPICH采用紧迫协议和约定协议来协调各个进程之间的通信 ,同时也提供了一些阻塞处理函数和非阻塞处理函数 ,它们能够使进程充分利用系统资源 。An elementary method of parallel programming using MPICH on PC cluster is expaticated in this paper. By an example of parallel program for computing the value of π, the routines of MPICH are introduced. While designing parallel program, the crucial technology is how to manage the communication among these processes. MPICH selects eager protocol and rendezvous protocol to assort with these communications. At the same time, MPICH supplies the blocking probe functions and non blocking probe functions, which make these processes to use resources fully and make user have more flexibility when developing programs.
