Edinet: An Execution Driven Interconnection Network Simulator for DSM Systems

Evaluation studies on interconnection networks for distributed memory multiprocessors usually assume synthetic or trace-driven workloads. However, when the final design choices must be done a more precise evaluation study should be performed. In this paper, we describe a new execution-driven simulation tool to evaluate interconnection networks for distributed memory multiprocessors using real application workloads. As an example, we have developed a NCC-NUMA memory model and obtained some simulation results from the SPLASH-2 suite, using different network routing algorithms.
