This was added to the 1.3 version - it was not back-ported to the
1.2.x series.

In an attempt to protect some users from themselves, I was hoping
that OpenMPI could be configured so that an MPI task calling
exit before calling MPI_Finalize() would cause job cleanup, i.e.
behave effectively as if MPI_Abort() was called. The reason is
that many users dont realise they need to use MPI_Abort()
instead of Fortran stop or C exit. If exit is called, all
other processes get stuck in the next blocking call and, for a
large walltime limit batch job, that can be a real waste of
resources.
I think LAM terminated the job if a task exited with non-zero
exit status or due to a signal. OpenMPI appears to cleanup
only in the case a signalled task. Ideally, any exit before
MPI_Finalize() should be terminal. Why is this not the case?
Thanks,
David
