Collective calls of MPI have to be called by each process included in the

Collective calls of MPI have to be called by each process included in the communicator appearing in the routine MPI ? so when the driver (or the psmile) makes a collective call within the global communicator, a similar call has to be put in the psmile (or the driver), else
