[mpich-discuss] mpiexec returns 0

[Jayesh Krishna]

Hmmm... not really. mpiexec provided with MPICH2 on windows returns the
last non-zero exit code (has nothing to do wether MPI_Finalize() was
called or not) returned from an MPI process associated with the job.
mpiexec also returns an error code if there is any error within mpiexec.
So if there is an error (in mpiexec OR in any MPI process) in the MPI job
you should be able to determine that by a non-zero return code from
mpiexec.

I would like to have a confirmation that mpiexec would return 0 if all
processes called MPI_Finalize(). Based on return value, some test scripts
can be stopped instead of having the output parsed.
