Comsol Guide

This how-to article explains how to load and run Comsol on HPC.

Instructions

comsol with MPI

To run comsol with SLURM, please create following comsol.sh:

#!/bin/bash

# For general partition
#SBATCH -N 1
#SBATCH -p general
#SBATCH --cpus-per-task=126
#SBATCH --ntasks-per-node=1
#SBATCH --output comsol.log

# Clear the output log
echo -n > comsol.log

# Add debugging information.
scontrol show job $SLURM_JOBID

# Details of input and output files.
INPUTFILE=/path/to/input_model.mph
OUTPUTFILE=/path/to/output_model.mph

# Load our comsol module.
module purge
module load comsol/6.2

# Run comsol.
comsol batch \
    -clustersimple \
    -np $SLURM_CPUS_PER_TASK \
    -mpifabrics shm:ofa \
    -inputfile $INPUTFILE \
    -outputfile $OUTPUTFILE \
    -tmpdir temp

Then submit the script by issuing:

$ sbatch comsol.sh

comsol with GPU

$ ssh <NetID>@login.storrs.hpc.uconn.edu
$ module load comsol/6.2

To run comsol with SLURM, please create following comsol.sh:

Then submit the script by issuing:

comsol on single node

Some comsol algorithms like PARDISO do not make use of MPI like . To run these, you can specify -np instead of -clustersimple as follows

Then submit the script by issuing:
