程序调试、监测与性能分析的一体化工具

An Integrated Tool for Debugging, Monitoring and Performance Analysis

随着高性能芯片及高性能计算的应用，人们对调试器的要求不再仅局限于“正确性调试”，而是更进一步要求进行“性能调试”，即在正确性的基础上，通过对程序的细调而获得最佳性能．正确性调试和性能调试通常由独立的工具支持，这种模式已不能很好地支持高性能计算．介绍了一个为高性能ＳＩＭＤ芯片设计的同时具有正确性调试和性能调试功能的可视化工具．它集程序调试、行为监测和性能分析为一体，改善了高性能程序的开发周期。

As the development of high performance computing, the requirement for debugging is not only limited in “correctness debugging”, but also for “performance debugging”, which means to achieve the best performance through program tuning. The correctness debugging and the performance debugging are usually supported by the separate tools, which couldn't sufficiently support high performance computing. A visualization tool is presented in this paper that supports both “correctness debugging” and “performance debugging” for a high performance SIMD chip. This tool incorporates the functionality of debugging, the behavior monitoring and the performance analyzing. It greatly improves the development cycle of high performance computing programming.
