I've tried to substitute MPI_SEND by MPI_SSEND in order to wait the completion of the MPI_RECV of the receiving
process before the send command returns, but MPI_SSEND seems to work like MPI_SEND (the receiver may not have
posted an MPI_RECV)...

What's going wrong with this statement ?

I'm using MPICH 1.1 with "mpirun -p4pg"

Help would be very appreciated ...
