Practical simulation of large-scale parallel programs and its performance anlaysis of the NAS parallel benchmarks

摘要

A simulation techniuqe for very large-scale data parallel programs is propoosed.In our simulation method,a data parallel program is divided into computation and communcaiton sections.When the contorl flow fo the parallel program does not depend on the contents of network messages,the ocmputation time on each processor is calculated independently.An instrumentation tool called EXCIT is used to calculate the executin time on the target architecture and generate messae traces.
