A Petri Net Toolkit For Parallel Program Debugging, Potla Kishore Reddy

Theses

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 …
