Abstract: This paper presents a visualization tool for evaluating performance of MPI-based parallel platform. This tool collects the utilization information of hardware resource when a program runs, and can be visualized by postmortem or real-time views. From these views programmers can monitor the performance, find out the performance bottleneck, and improve the performance.

摘要： 介绍了一个基于MPI编程环境的性能监测/分析工具，该工具对程序运行时的相关硬件系统资源数据进行采集，提供实时和事后两种可视化视图，以便程序员对程序进行实时监测和事后性能分析，帮助找出性能瓶颈并加以改进，提高并行程序的性能。
