I can't reproduce that (with openmpi tight integration). Doing this
(which gets three four-core nodes):
qsub -pe openmpi 12 -l h_vmem=256M
echo "Script $(hostname): $TMPDIR $NSLOTS"
ulimit -v
for HOST in $(tail -n +2 $PE_HOSTFILE|cut -f1 -d' '); do
qrsh -inherit $HOST 'echo "Call $(hostname): $TMPDIR $NSLOTS"; ulimit -v;
sleep 60' &
done
wait
I see:
Script node193: /tmp/179483.1.parallel 12
1048576
Call node228: /tmp/179483.1.parallel 4
1048576
Call node214: /tmp/179483.1.parallel 4
1048576
