1 HIGH-FIDELITY MODELLING AND SIMULATION OF MYRINET SYSTEM AREA NETWORKS

This paper presents a high-fidelity, event-driven model for performance analysis of various applications on Myrinet system area networks (SANs). The model is designed for the Block-Oriented Network Simulator (BONeS) commercial CAD environment for discrete-event simulation, is accurate down to the Myrinet character level, and supports a wide variety of topologies and parameter permutations. An analytical model is also presented by which the simulation model is verified, and validation of the simulation model is achieved through comparisons with experimental testbed results on both networking and parallel computing tests. In addition, a case study on performance analysis of Myrinet-based networks and clustered computers is included, where the impact of Myrinet data rate and buffer size on communication and computing performance is examined, further demonstrating the flexibility and versatility of the new simulation model
