Thanks.
If you have time could you please explain why it is required that
we need to call MPI_Wait after MPI_Isend? Irecv case is needed from the
programmers perspective, but as a programmer I do not need to wait for the
completion of MPI_Isend. It is the programmers responsibility to ensure
the re-usage of his/her programs buffers as in the some other send modes.
I really want to know the MPI developers' rationale behind this.
