I am trying to run the OpenFOAM jobs on multiple nodes. However, encountering some difficulties to do so. Here is my job script.
\\ script starts \\
#PBS -q small
#PBS -l select=2:ncpus=40:vntype=cray_compute
#PBS -l place=scatter
#PBS -N refined_mach8_1
#PBS -j oe
splitMeshRegions -cellZones -defaultRegionName fluid -overwrite
decomposePar -allRegions -dict system/decomposeParDict
mpirun -np 80 -oversubscribe chtMultiRegionFoam -parallel
\\ 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.
