In recent years, workstation clusters have become popular for solving scientific problems and running computation-intensive simulations in parallel. We present a simple CSP-based model of this kind of computing, suitable for dedicated clusters as well as for enterprise clusters connected via Ethernet. A Transim tool can be used to simulate various parallel applications running on workstation clusters. Since communication latency is quite high in clusters, prediction of processor utilization, obtainable speedup and execution time are of interest. The Transim tool enables to find all these figures in minimum time and with minimum effort. As an example, a solution of a large system of (1000+) linear equations on 8 workstations connected via a hardware router is simulated and results are presented.
A simple CSP-based model of cluster computing, suitable for clusters with star topology and hw router (Omega network) is presented. Use of the Transim tool for simulation of parallel applications running on such clusters has been demonstrated.
