软件DSM系统的重放

Replay of Software Distributed Shared Memory System

软件 DSM系统的并行调试环境已经成为制约其广泛应用的一个重要因素 .重放方法使得用户能用循环调试技术来调试具有执行不确定性的软件 DSM程序 .本文定义了软件 DSM程序执行的 happen- before- 1关系 ,并依据其提出一种在软件 DSM系统 JIAJIA上实现重放的方法 .实际应用测试表明 。

The Parallel Debugging Environment is an important aspect which restricts the extensive application of Software DSM System. By replay technique, the programmers can use cycle debugging technique to debugging their indeterminate JIAJIA programs. The Happen Before 1 relation has been defined to describe the software DSM program's execution, and according to it,an implementation of replay technique has been suggested. The experimental results show that the implementation produces little space and time overhead.
