并行程序调试中的环境再现技术

Environment Reappearing Technique in Debugging a Parallel Program

为解决调试并行程序碰到的第一个困难:并行程序的不确定性,文中提出了环境再现技术。文中叙述了环境再现技术的思想和实现这一技术需要的数据结构,并用CCNPASCAL语言进行了描述,最后给出了一个典型的应用例子。

The first problem of debugging a parallel program is the nondeterminancy of the program. The environment reappearing technique presented in this paper can solve the problem quite well. The paper discribes the idea of the technique, the data structure needed for it and gives a pidgin CCNPASCAL languge description of it. An example of the technique is briefly given in it.
