基于程序定义及动态进程的PVM与MPI比较

MPI（Message Passing Interface）与PVM（Parallel Virtual Machine）均为分布式计算中广泛应用的两种并行计算环境。PVM出现的时间早于MPI，且它是一个自包含系统，而MPI是一个标准。目前，在PVM与MPI互相靠拢的过程中，关于两者的比较越来越多。其目的便是通过比较，结合二者之优点，发展起性能更加强大的并行计算环境。仅从程序的定义与实现、以及动态进程两个方面简单阐述了两者的不同，事实上，二者通常被用于解决不同的问题。

Comparison between PVM and MPI Based on Programming Definition and Dynamic Programming

MPI(Message Passing Interface) and PVM(Parallel Virtual Machine) are both parallel computing environments,widely used in distributed computing.The emergence of PVM is early than MPI.The PVM is a self-included system,while the MPI is a standard.Today,they both are looking forward to a combination,thus,comparisons between them are increasingly more.This paper just does comparisons in two aspects of definition and implementation,as well as dynamic processes.In fact,the two systems are often solving different p...
