【摘要】 本文以并行矩阵乘法为例子，给出在ＰＶＭ，ＥＸＰＲＥＳＳ以及ＮＸ环境上的并行程序实现．通过对这个简单例子的分析，归纳出在一般情况下并行程序设计应采取的策略．这里介绍的并行程序设计方法，特别对大型应用问题的并行移植是非常有用的，其目的是为想写并行程序的科研人员提供参考更多还原

【Abstract】 In this paper, the author takes parallel matrix multiplication as an example to see how their parallel implementations are under PVM, EXPRESS and NX environments. By analyzing this simple problem, the strategies of parallel programming are summarized for general purposes. The given parallel programming method is specially useful for parallel porting of a large scale application. The purpose of this paper is to provide a reference for scientists who want to write parallel programs.更多还原
