MPI-SIM: Using Parallel Simulation to Evaluate MPI Programs

Abstract

This paper describes the design and implementation of MPI-SIM, a library for the execution driven parallel simulation of MPI programs. MPI-LITE, a portable library that supports multithreaded MPI, is also described. MPISIM, built on top of MPI-LITE, can be used to predict the performance of existing MPI programs as a function of architectural… (More)
