Running jobs

Running Mechanical over MPI on many nodes (example):

#!/usr/bin/env bash
#SBATCH -A PROJECT_NAME
#SBATCH -p vera
#SBATCH -n 128
#SBATCH -t 48:00:00

module load ANSYS/2023R1
cp proj.dat $TMPDIR
cd $TMPDIR
sed 's/ cpu=/:/' lamnodes > machines && sed -i ':a;N;$!ba;s/\n/:/g' machines
export MACHINES=$(cat machines)
ansys181 -dis -mpi intelmpi -b -machines $MACHINES < proj.dat
cp $TMPDIR/* $SLURM_SUBMIT_DIR

Suitable arguments for multi-node parallel Fluent:

-pinfiniband -ssh -cnf=$TMPDIR/mpichnodes -g

For multi-node parallel CFX, add the following line to your job script:

nodes="`sed -e :a -e N -e 's/\n/,/' -e ta $TMPDIR/mpichnodes`"

and the following to your cfx-commandline:

-par -par-dist $nodes -start-method "HP MPI Distributed Parallel"
