    Dear Kenneth,

    Thanks for your quick reply.
    I tested your suggestion and, unfortunately, this approach didn't work.

    Question: when I call MPI_IPROBE it accounts also for the messages
    that were already received asynchronously?

That should not be the case. If a message has been matched by a recv/irecv, MPI_Probe should not match it again.

    Is there any way to know, for my list of mpi_requests (from my
    MPI_IRECV's), which ones are "opened" and which ones have messages?

MPI_Test will take a request as an argument and tell you whether or not that requested operation has been completed.

Ken
