Abstract
Presents performance results for three distributed computing environments using the three simulated computational fluid dynamics applications in the NAS Parallel Benchmark suite. These environments are the Distributed Computing Facility (DCF) cluster, the LACE cluster, and an Intel iPSC/860 machine. The DCF is a prototypic cluster of loosely-coupled SGI R3000 machines connected by Ethernet. The LACE cluster is a tightly-coupled cluster of 92 IBM RS6000/560 machines connected by Ethernet as well as by either FDDI or an IBM Allnode switch. Results of several parallel algorithms for the three simulated applications are presented and analyzed, based on the interplay between the communication requirements of an algorithm and the characteristics of the communication network of a distributed system.Keywords
