Hello Foamers,

I am trying to run the OpenFOAM jobs on multiple nodes. However, I encountered some difficulties in doing so. Here is my job script.

\\ script starts \\

#!/bin/bash
#PBS -q small
#PBS -l select=2:ncpus=40:vntype=cray_compute
#PBS -l place=scatter
#PBS -N refined_mach8_1
#PBS -j oe
cd $PBS_O_WORKDIR

blockMesh
topoSet
splitMeshRegions -cellZones -defaultRegionName fluid -overwrite
decomposePar -allRegions -dict system/decomposeParDict
mpirun -np 80 -oversubscribe chtMultiRegionFoam -parallel
reconstructPar -allRegions

\\ script ends \\

The issue is the cluster is acquiring two complete nodes, however, running the job only on one node. If anybody could provide valuable input, it would be conducive.
