I should add to my mention of MPI_Quit that I am not at all confident that
a clean & portable semantic is possible.
I am not suggesting anything that provides subset synchronizations or
application notifications. No promise of message delivery among other
tasks. No promise that other tasks reach a standards defined state before
If MPI_Quit means anything more than a promise by libmpi that all tasks
will be terminated and all resources recovered, it becomes a much more
A call to MPI_Quit would let the application give a return code of 0 so a
script or wrapper that checks the mpiexec return code would regard the
application as a success.
