[Paraview] pvserver submission thru qsub/PBS

Fri Apr 17 11:26:38 EDT 2009

I also use reverse connection with Torque (same commands used by PBS).

Here it goes the script that I use to start my PV session (reverse
connection and offscreen rendering):

#====================================================================
#PBS -l nodes=1:ppn=8
#PBS -l walltime=12:00:00
#PBS -N pv-omp
#PBS -j oe
#PBS -V
# PBS -m ae
# PBS -M user at domain.ufrj.br

PVCLIENT=ip.to.pvclient.machine

export
LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/sw/shared/x86_64/paraview/openmpi/3.4.0/lib/paraview-3.4:/sw/shared/x86_64/Mesa/7.2/lib64

# change directory
cd ${PBS_O_WORKDIR}

# get the number of processors and nodes
NUM_PROC=`cat ${PBS_NODEFILE} | wc -l`

# mpi program launch
mpirun -np ${NUM_PROC} /sw/shared/x86_64/paraview/openmpi/3.4.0/bin/pvserver
--use-offscreen-rendering -rc -ch=${PVCLIENT}

#====================================================================

Of course, you'll need to leave your pvclient waiting the reverse
connection.

I hope it helps you...

Regards

Renato.
