Abstract

In this paper, we discuss the parallelization of power systems simulation using modern clusters consisting of multi-core compute nodes interconnected by a low latency interconnect. We describe an implementation strategy that exploits three types of parallelization that are amenable to the various types of inter-core “connectivity” commonly seen in such clusters. We also consider a set of design criteria that are important to Small-Medium Enterprises (SMEs) and how they affect implementation strategy. We report the results of some initial experiments done using components that will form a part of the prototype system under construction and then discuss the expected performance gains for the entire system based on manpower invested. We also identify several key factors in design for SMEs that differentiate their parallel systems needs from those of large organizations and research scientists.
