However this idea is not suitable for collective and MPI_ANY_SOURCE sends/recvs.</div><div><br></div><div>Exist another way to join all the inter-communicator into one? </div><div><br></div><div>Any suggestion?</div><div><br></div><div>Best regards.</div><div><br></div><div><br></div><div><br></div><div><br><div>
