MPI_Wait does not guarantee that the data sent with MPI_Isend is received. It merely means you can reuse the send buffer. If you want to be sure it has been received, use MPI_Issend (synchronous send).
MPI_Ssend or MPI_Issend completing only guarantees that the receiver has posted the matching receive, not that the data has been completely transferred to the receiver's buffer. -Dave _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
