Fluent 14.0 file not running in parallel mode in cluster
 

Hi,

I have created a fluent 14.0 file to be run in cluster. When I give the series command the file is running in 1 core but when I give the parallel command also the file is running only in 1 core. The cluster is allocating 8 cores but the file is running only in 1 core. Below are the PBS scripts and journal files.

PBS Parallel

#! /bin/bash
#PBS -o logfile1.log
#PBS -e errorfile1.err
#PBS -l cput=740:00:00
#PBS -l select=1:ncpus=8
tpdir=`echo $PBS_JOBID | cut -f 1 -d .`
tempdir=$HOME/work/job$tpdir
mkdir -p $tempdir
cd $tempdir
cp -R $PBS_O_WORKDIR/* .
fluent 3ddp -g –t8 -pib -cnf=$PBS_NODEFILE -ssh -i srik1.jou >> out
mv ../job$tpdir $PBS_O_WORKDIR/.


PBS Serial

#! /bin/bash
#PBS -o logfile2.log
#PBS -e errorfile2.err
#PBS -l cput=500:00:00
#PBS -l select=1:ncpus=1
tpdir=`echo $PBS_JOBID | cut -f 1 -d .`
tempdir=$HOME/work/job$tpdir
mkdir -p $tempdir
cd $tempdir
cp -R $PBS_O_WORKDIR/* .
fluent 3ddp -g -i srik1.jou
mv ../job$tpdir $PBS_O_WORKDIR/.

Journal File

/exit/yes


Licenses are availbale on the cluster on all the nodes and cores but my file is not running in all the cores even when I am submitting it in the parallel mode command. Please help me out as I dont know why it is running only in one core and not all the 8 cores?
