[torqueusers] Problem to allocate more than one node

[Albino Aveleda]

Hi,

I have a cluster with 4 nodes with 8 cores each node.
I installed torque 2.2.1, but I can use more than one
node in same job. Please, look the smaple bellow that
I asked 2 nodes (16 cores), but torque allocate only
one node as showed in exec_host line.

What's wrong in my configuration?

[bino at adm test]$ cat test.job #PBS -l nodes=2:ppn=8
#PBS -l walltime=01:00:00
#PBS -j oe
#PBS -N test
# change directory
cd ${PBS_O_WORKDIR}
# get the number of processors and nodes
NUM_PROC=`cat ${PBS_NODEFILE} | wc -l`
# run
echo "Num Proc: $NUM_PROC"
cat ${PBS_NODEFILE}
