Abstract

This paper describes a software tool, LAPSE (Large Application Parallel Simulation Environment), for the simulation of large-scale programs written for the Intel Paragon, executed on smaller-scale machines. Two timing simulators are themselves parallelized; this paper describes the conservative synchronization algorithm we have developed to synchronize the simulation. We present performance data taken from LAPSE runs of an indirect linear system solver where we consider issues of simulated network complexity, and processor usage
