Forgive me if you received the same message more than once. I may have

Hello everybody

I am a little bit confused with the following description of MPI_Probe
which I found in the book, "MPI compelete reference". I would
appreciate any help about this.

"The semantics of MPI_PROBE guarantees progress, in the same way as a
corresponding receive executed at the same point in the program."

Does this mean that a call to MPI_Probe should complete a matching
sync-send just as a matching MPI_Recv would do?  Does this also mean
that a standard-send that has been blocked due to lack of the buffer
space should progress with the presence of a matching MPI_Probe?

Thank you.
