cannot work parallel nodes

[kobl1201]

Hi

when i work out ROMS model, I try to use 2 cpu, but the cpu continues to work with 1.

When i set paralle node =1, the model work out well.

which option can I check??

---------------------------------
It is my run.sh file

#!/bin/bash

#PBS -V
#PBS -q batch
#PBS -l nodes=2:ppn=1
#PBS -N ROMS

ulimit -s unlimited
ulimit -c unlimited

cd $PBS_O_WORKDIR


cp -f $PBS_NODEFILE .

echo $PBS_NODEFILE > ./test.prt
echo "job started"
date
NP=`/usr/bin/wc -l $PBS_NODEFILE | awk '{ print $1 }'`

echo "$NP" >> test.prt
mpirun -np 2 -machinefile $PBS_NODEFILE ./romsM ocean_ub_3k_new.in >> test.prt

date
echo "job finished"

if you set to run with -np X, where X is an integer, then you need to change ocean.in values of NtileI and NtileJ so that
NtileI * NtileJ = X

an example is
-np 2
NtileI=1
NtileJ=2
