Unified Parallel Debugged Object Model for PVM
-
摘要: 研究了PVM(Parallel Virtual Machine)系统,利用活动(action)概念具体定义了PVM应用程序的活动,从而描述出一种新型的PVM调试对象模型,使得在调试的各阶段能够对相同的调试对象采用不同的调试方法,简化了调试工作.

Abstract: It is important to well understand the debugged parallel program in researching and developing its parallel debuggers.Although many parallel debuggers define events to be occurrence instances of program actions,little of them give the complete definition of action. PVM(Parallel Virtual Machine) system is analyzed, and concrete actions are defined,which are used to describe a unified PVM debugged object model for PVM.A same debugged object can be provided in all debugging periods when using this model,this makes parallel debugging more easy.-
