Abstract
Source level debuggers for parallel PVM or MPI programs currently offer good support for debugging multiple processes, however, they still lack adequate mechanisms for debugging message passing errors. In this paper, we present a new concept called message breakpoints, which allows to follow the information flow between processes. We also show how these breakpoints can be implemented very efficiently by using invisible message tags and will demonstrate other applications of this technique in the context of distributed event detection.
