摘　　要：DENNET是清华大学高性能计算所开发的一个机群系统并行程序调试环境 .本文分析并行程序调试环境的现状和发展趋势 ;阐述调试环境对并行程序的干扰问题 ,指出降低乃至完全消除干扰是并行程序调试环境的一个重要研究方向 ,介绍了 DENNET设计时采用的两种降低干扰的技术 .DENNET is a debugging environment for cluster systems developed by Tsinghua University. After analyzing the researching trend of debugging environments, we point out the problem of disturbance that a debugging environment imposed on a debugged parallel program. Reduction, even complete elimination this disturbance is an important researching direction in the field of debugging environment. We also present a prototype of debugging environment-DENNET that shows the applications of some techniques of reducing disturbance.
