Pvm并行调试器DPD中的时序处理

Handling time-sequence in Pvm parallel debugger DPD

针对并行调试器中传统排序模型的缺陷 ,提出了一套改进的时序处理机制 .该机制是在调试系统中加入一个全局记录器 ,被调试模块在需要事件记录时向全局记录器申请一个全局序号 ,这样并行模块的事件就被自然地串行化 ,从而实现了并行程序时序的完全排序 .该方法大大简化了排序过程 ,给记录

This paper proposed an improved mechanism for handling time sequence based on the traditional sort model. A global recorder was inserted and the debugged modules applied for the global serial number when recording of events required. By means of that, the events of parallel modules can be serialized and the whole sorting of the parallel time sequence can be achieved. This simplified the sorting procedure and gave a strong support for Pvm parallel debugger.
