I'm writing a simple post-mortem profiling tool that provides some of the information that you are looking for. That being said, the tool, Loba, isn't publicly available just yet. In the mean time, take a look at mpiP (http://mpip.sourceforge.net/

to know. It sounds like you want to be able to watch some % utilization of
a hardware interface as the program is running. I *think* these tools (the
ones on the FAQ, including MPE, Vampir, and Sun Studio) are not of that
You are correct. A real time tool would be best that sniffs at the MPI
traffic. Post mortem profilers would be the next best option I assume.
I was trying to compile MPE but gave up. Too many errors. Trying to
decide if I should prod on or look at another tool.
