Simulation of modern parallel systems

Abstract

Components of modern parallel systems are becoming quite complex with many features and variations. An integrated modeling of these components (interconnection network, messaging layer, programming model, and computation-communication characteristics of applications) is essential to derive design guidelines for next generation parallel systems. Most of the current simulation-based modeling platforms do not support such integrated modeling. This paper presents our effort at The Ohio State University towards integrated modeling of parallel systems. Basic features of our CSIM-based Wormholerouted Multiprocessor Simulator (WORMulSim) are outlined.
