Subject: Re: [OMPI users] Check whether non-blocking communication has finished?

Perhaps often it is more useful to use MPI_WAIT rather than MPI_TEST type
fucntions, because at MPI_WAIT point it will be taken care of communication
completion, automatically, which may be necessary before going ahead. with
MPI_TEST it would become the responsibility of the programmer to handle the
situation if the test is FALSE/FAILED.
