Subject: Re: [OMPI users] Possible openmpi bug?

 From what I can see, it looks like your job is being terminated -
something is killing mpirun. Is it possible that the job runs slowly
enough on 14 or less cpus that it simply isn't completing within your
specified time limit?

The lifeline message simply indicates that a process self-aborted
because it lost contact with its local daemon - in this case, mpirun
(as that is always daemon 0) - which means that the daemon was
terminated for some reason.
