Hi,
Open MPI does not do this out of the box.
MPI profilers can achieve that. Some are commercials (ITAC from Intel,
MAP from Allinea/ARM) and some are free (Score-P)
An other option is to build your own mini-profiler with the PMPI interface.
You can find an example at

Cheers,
Gilles

Hello,
Is there any way to detect the number of exchange messages between the
MPI processes ?
Many thanks in advance.
