Simulation of Modern Parallel Systems: A CSIM-based Approach

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. A set of techniques used in our simulator to model different network components (such as switches, links, wormhole/cut-through switching techniques, routing protocols, network interfaces), messaging layer with basic communication primitives, distributed shared memory programming model, and computation-communication characteristics of applicati...
