Abstract :
We describe our experience in implementing an instrumentation system for post-mortem ParaGraph visualization of PVM programs. The instrumentation system can be enabled without adding explicit startup code to the original program. Furthermore, processes can enroll into the instrumentation system at any point during the execution of the application, allowing for algorithms with arbitrary parallelism. We also provide additional facilities like user task labeling and an intelligent process graph layout interface to help the programmer relate performance data to the profiled distributed application
