Serial Job

This script runs a serial, single-CPU job using the standard queue.

Any line beginning with #SBATCH issues a SLURM directive that controls aspects of your job such as job name, output filename, memory requirements, number of CPUs, number of nodes, etc.

To run the script, replace YOUR_GROUP with the name of your PI’s group on HPC. To find this information, you can use the command va. You can submit the job with sbatch <script_name>. This job assumes there is a python script in your working directory (included in downloadable example above).
