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.

How is this different than calling MPI_Abort with an error code of 0? Is it just that MPI_Quit would do more than 'best effort'? -Fab
