Abstract

Writing parallel programs is more difficult than serial programming. So or somehow similar most papers about parallel processing start. Parallel programming alone is not that difficult but writing efficient and error free parallel programs can be a very tedious job.

In our paper we propose a strategy for debugging parallel programs on distributed memory machines. We follow a method called trace driven simulation [10, 11, 12] that has proven to be successful in finding several types of errors in parallel programs. During our work we developed a monitoring strategy as well as tools for visualization and inspection of recorded program traces. The whole concept is covered by a similar philosophy as UNIX (“keep the tools small and clear”) but with an extension to the “look and feel” concept that is known from modern graphical user interface design. Therefore we are developing handy tools in a modular way. The integration of all tools leads to our debugging environment.
