Network-based concurrent computing on the PVM system

Concurrent computing environments based on loosely coupled networks have proven effective as resources for multiprocessing. Experiences with and enhancements to version 1.0 of PVM (Parallel Virtual Machine) are described in this paper. PVM is a software package that allows the utilization of a heterogeneous network of parallel and serial computers as a single computational resource. Further, this report also describes an interactive graphical interface to PVM, and porting and performance results from production applications.. Authors: Geist, G. A.
