If you don’t specify a slot count, then we will automatically detect the #cores
on the machine and set the slot count to that number.
You can add —map-by node to your cmd line and that will give you the prior
behavior as we’ll round-robin one proc on each node at a time

Hello,
I'm trying to use openmpi 1.8.8 on a cluster managed by OAR, however i have
some troubles with the default slots number.
I have reserved one core on two nodes (each has 12 cores):
# cat $OAR_NODEFILE
nef097.inria.fr
nef098.inria.fr
but:
mpirun -np 2 --mca plm_rsh_agent oarsh -hostfile $
