- Copy the .mph-file to your HOME or WORK directory (depending on where you want to run your simulation)
Create a SLURM script, e.g. using vi, emacs, ... any ASCII editor available
Take care to estimate the length of your job conservatively! Simple scaling tests on a smaller case can be of help! Select the NTASKS-PER-NODE and OMP_NUM_THREADS according to the architecture you are running Comsol on! Hint: NTASKS-PER-NODE * OMP_NUM_THREADS should be equal the total number of CPU cores per node!
Concerning the MPI fabrics: If you want to use Comsol on CoolMUC-3,
I_MPI_FRABRICSmust be set to
shm:tmi. Alternatively, you can also use
-mpifabrics shm:tmion the command-line. For CoolMUC-2, it was tested with
Submit the job!
- Using the SLURM tools (and also the --mail-type tag), you can get updates about the status of your job
- Copy the output result file back and open it in Comsol GUI (locally on your Laptop/PC or on the LRZ Login or Remote Visualization Nodes) for post-processing
