[OMPI users] CPU and communication usage

[Oskar Pusz]

Hi there!
Just a simple question:

I need to examine two things:
- cpu usage
- communication usage

during MPI app running time. I found a few thing but I'm looking for new 
ideas already.

What i mean with -communication usage-: I want to know more about the 
messages between the ranks in e.g. number of messages, size in bytes 
and/or "band width" when/while MPI_Recv respectively MPI_Send occurs.

Is there a "simple" way to get these informations?
Many thanks in advice!

Greetings,
Oskar
