Job script threaded version (no MPI)
You can use only one node in this case. Create a job file called job_smp.sh
:
/opt/ohpc/pub/examples/slurm/mul/comsol
#!/bin/bash # #SBATCH -J comsol #SBATCH -N 1 #SBATCH -o job.%j.out #SBATCH -p E5-2690v4 #SBATCH -q E5-2690v4-batch #SBATCH --ntasks-per-node=28 #SBATCH --threads-per-core=1 #SBATCH --time=04:00:00 #SBATCH --mem=16G # Details of your input and output files INPUTFILE=micromixer_cluster.mph OUTPUTFILE=micromixer.out # Load our comsol module module purge module load COMSOL/5.2a # create tmpdir TMPDIR="/tmp1/comsol" mkdir -p $TMPDIR ## Now, run COMSOL in batch mode with the input and output detailed above. comsol batch -np $SLURM_NTASKS -inputfile $INPUTFILE -outputfile $OUTPUTFILE -tmpdir $TMPDIR
