Batch system examples

We have made a few examples of how to use the batch system, both from the command line and through a batch submit file.

Overview of the Batch system examples subpages:

Examples, scripts

Example job submission files

'Job submission file' is the official SLURM name for the file you use to submit your program and ask for resources from the job scheduler. Here we will be using it interchangeably with 'script' or 'batch script'.

Commands to the batch scheduler is prefaced with #SBATCH, these are also called directives. You can also add normal shell commands to the script.

All SLURM directives can be given on the command line instead of in the script.

Remember - the scripts and all programs called by them, must be executable!

Examples, srun

Examples, srun

You can submit programs directly to the batch system with 'srun', giving all the command on the command line, though you should normally use a jobscript and submit it with 'sbatch', for larger or more complicated jobs.

More information about parameters and job submission files can be found on the Slurm submit file design page.

Running two tasks, each on a different core.

$ srun -A <account> -n 2 my_program

Run 6 tasks distributed across 2 nodes.
