Slurm Submission Scripts
The following is a typical Slurm submission script.
#!/bin/sh #SBATCH -n 16 # 16 cores #SBATCH -t 1-03:00:00 # 1 day and 3 hours #SBATCH -p compute # partition name #SBATCH -J my_job_name # sensible name for the job # load up the correct modules, if required . /etc/profile.d/modules.sh module load default-gcc-openmpi-apps-libs-recommended # launch the code mpirun ./cpi.x
How to submit a job
To submit this, run the following command:
Note that this is for OpenMPI compiled applications, for other MPI implementations you may need to adjust the
mpirun line. See here for more details.
Warning: do not execute the script
The job submission script file is written to look like a bash shell script. However, you do NOT submit the job to the queue by executing the script.
In particular, the following is INCORRECT:
# this is the INCORRECT way to submit a job ./myscript.sh # wrong! this will not submit the job!
The correct way is noted above (
Missing Libraries/Module Issues
If your script fails because it is unable to find libraries then you will have to configure the environment modules - see here for more.
