Many computational endeavors benefit from some form of parallelization, and SLURM provides a way to do “embarrassingly parallel” processing relatively simply (read more about parallelization here). Additionally, submitting a SLURM array puts all parts of the job (tasks) under one job ID, which simplifies canceling or otherwise managing dozens/hundreds/thousands of jobstasks.
Basics
Array submission works via the “--array” option of sbatch (read more about it here). This requires the start, stop, and optional step size for your array indices – each index will be given its own task ID.
