run parallel distributed in cluster
 
Hi all,

I want run my fluent case in a cluster using several nodes and processors (I'm using Torque as manager in the cluster). The PBS journal is:

#PBS -N LSVOFaxi
#PBS -m ae
#PBS -M user@domain.com
#PBS -l nodes=2:pn=4 (the face are two point, I don't know why appears it)

FLUENT_PATH=/cluster/apps/ansys_inc/v140/fluent/bin

cd ${PBS_O_WORKDIR}
$FLUENT_PATH/fluent 2ddp -g -ssh -pinfiniband -t8 -cnf=/home/Documents/LSVOFaxi/fluenthostsn2p4 -i LSVOFaxi.txt > LSVOFaxi.log

The hosts file (fluenthostsn2p4) is:

r1i0n2
r1i0n2
r1i0n2
r1i0n2
r1i0n15
r1i0n15
r1i0n15
r1i0n15
<white line>

But this not worked.
I think that the error is in the following line command, but I don't know:

$FLUENT_PATH/fluent 2ddp -g -ssh -pinfiniband -t8 -cnf=/home/Documents/LSVOFaxi/fluenthostsn2p4 -i LSVOFaxi.txt > LSVOFaxi.log

If anyone know solve it, please help me.

Thank you.

When I ran parallel local, with 1 node and 4 processors, using the following PBS journal, this worked.

#PBS -N LSVOFaxi
#PBS -m ae
#PBS -M user@domain.com
#PBS -l nodes=1:ppn=4 (the face are two point, I don't know why appears it)

FLUENT_PATH=/cluster/apps/ansys_inc/v140/fluent/bin

cd ${PBS_O_WORKDIR}
$FLUENT_PATH/fluent 2ddp -g -t4 < LSVOFaxi.txt > LSVOFaxi.log
