Thanks again Kenneth, I could solve using MPI_TESTANY. Regards, Luiz On 13 March 2014 15:35, Kenneth Raffenetti <[email protected]> wrote:

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
