摘要

本文描述了一个工具，LAPSE(大型应用程序并行仿真环境)，它允许使用少量并行处理器来模拟在大量处理器上运行的消息传递代码的行为，以进行可伸缩性研究和性能调优。LAPSE是在Intel Paragon上实现的，并且在处理大型问题时实现了较小的减速(相对于本机代码)和较高的加速。

A distributed memory LAPSE: parallel simulation of message-passing programs

This paper describes a tool, LAPSE (Large Application Parallel Simulation Environment), that allows one to use a small number of parallel processors to simulate the behavior of a message-passing code running on a large number of processors, for the purposes of scalability studies and performance tuning. LAPSE is implemented on the Intel Paragon, and has achieved small slowdowns (relative to native code) and high speed-ups on large problems.
