Hi Hicham -
You should look into probe(). I the result of a probe will give you a valid MPI_Status, which contains the tag and source. You can use this tag to determine how you can construct an appropriate recv().

If from the root process I both mpi::broadcast() and mpi::send(), will a receiver process be able to use probe() to see if a message that was either sent or broadcast is available?
probe() checks only for messages sent by send(), not by broadcast(). Matthias
