High-Performance PVM Based on Fast Message Passing
Huaxia Xia · 2001
PVM (Parallel Virtual Machine) software is one of the most popular software environments used on parallel workstation cluster system. However, with the rapid increase in the speed of local area networks as well as in the performance of workstation, PVM, which is based on the low-efficiency internal and the low-efficiency communication protocol, has become the bottleneck of the cluster systems. In this paper, it is explained how PVM restrains the performance of clusters, by pointing out and analyzing the limitation of PVM's mechanism. Then the details of the design and implementation of HPVM (High-performance PVM) are given, which is based on a high-speed reduced communication layer named FMP (Fast Message Passing).
