After some offline discussion, Aurelien and I think that we should probably keep the text as is. It will be more backward compatible and provides the best guidance for MPI_INIT behavior. This ticket can probably go. On May 8, 2013, at 10:23 AM, Richard Graham <[email protected]> wrote:
I do not thing there was any conclusion here - this is even true when one is not worrying about FT. What do you do when mpirun does not give you the number of process you asked for ? Before MPI_INIT we are not guaranteed to have more than a single "process".

Is there anything else from this ticket that we would find useful before killing it? For example, all of the text we have about MPI_INIT in ULFM is in an advice to implementors. Should we move anything to normative text?

This ticket specifies the behavior of the MPI library after a during MPI_INIT. Basically, if there is a failure during INIT, the library should return an appropriate return code and calling any other MPI function (with a few exceptions) is erroneous and will trigger the error handler for MPI_COMM_WORLD, which by default is MPI_ERRORS_ARE_FATAL and cannot be changed in this instance.
Again, this ticket has no discussion attached to it. I remember some discussions from the RTS proposal days, but I don't remember the results of any of those discussions. Can anyone else bring this back to light? _______________________________________________ mpi3-ft mailing list [email protected] http://lists.mpi-forum.org/mailman/listinfo.cgi/mpi3-ft
