Two obvious choices include:
- Use the MPE package from Argonne national lab. It produces data
files after a run that can be used with a java GUI to display a
pictorial depiction of your message passing patterns.
- Insert your own profiling function calls (e.g., override MPI_Send) to
gather your own statistics and then turn around and call the "real"
MPI_Send by calling PMPI_Send. Check out the Profiling chapter in the
MPI-1 standard for details.
There's other commercial tools out there for this kind of stuff, but I
am guessing that you'll want to start with the free stuff first.
