Hi,
this Slurm bug has been fixed and it will be available in 14.03.1
which will be released soon. Otherwise it is available in the HEAD.
You should find a core file of slurmstepd in the directory where you
have run the srun command.

Not sure if this is a SLURM or OMPI issue so starting here..
The OpenMPI FAQ mentions an issue with slurm 2.6.3/pmi2.
https://www.open-mpi.org/faq/?category=slurm#slurm-2.6.3-issue
I have built both 1.7.5/1.8 against slurm 14.03/pmi2.
When I launch openmpi/examples/hello_c on a single node allocation:
srun --mpi=pmi2 -N 1 hello_c:
srun -N 1 --mpi=pmi2 hello_c
srun: error: _server_read: fd 18 got error or unexpected eof reading
header
srun: error: step_launch_notify_io_failure: aborting, io error with
slurmstepd on node 0
srun: Job step aborted: Waiting up to 2 seconds for job step to finish.
srun: error: Timed out waiting for job step to complete
with --slurmd-debug=9: (I'm not sure what is the meaning of "ip
111.110.61.48 sd 14"
below, is that ip as in ip address? It is not the ip address of any
Nodes in my partition)

Launching with salloc/sbatch works.
