消息传递接口(MessagePassingInterface,MPI)和并行虚拟机(ParallelVirtualMachine,PVM)是两种广泛应用的网络分布式并行计算环境。论文首先介绍了消息传递接口和并行虚拟机两者各自的起源和特点,然后在此基础上从可移植性、点对点通信、集体通信、资源管理和容错能力等多方面分析和比较了这两者的功能特点。
Message Passing Interface (MPI) and Parallel Virtual Machine (PVM) are two widely used network distributed parallel computing environments. The thesis first introduces the origin and characteristics of both messaging interfaces and parallel virtual machines, and then analyzes and compares these two aspects from the aspects of portability, peer-to-peer communication, collective communication, resource management and fault tolerance Features.
