Abstract:	An effective debugger must support the language and operating system resource abstractions that are available to the programmer. Earlier debuggers worked at the machine architecture level: they dealt with machine instructions and registers. Current debuggers, designed for single process debugging, permit access to program variables and breakpoints and single-stepping at the level of high-level language statements. Eventhough the current debuggers, are already implemented to be a powerful tool, they still cannot do a job of parallel debugger. In this thesis, a computer simulation system has been established by Petri Nets execution providing a convenient and friendly interface as it allows the user to do parallel program debugging. The Parallel Debugger is simulated by providing a time parameter for each transition and thus simulating the net performance. Hitherto, this time parameter can either be constant or exponentially distributed.
