The national systems use a job scheduler called “Slurm”. In this session you will learn how Slurm works and how it allocates jobs, helping you to: minimize wait time by framing reasonable requests; ask for only the resources you need, to improve efficiency; increase throughput; run more jobs simultaneously; and troubleshoot and address crashes. This workshop is designed for new HPC users, or for experienced users either transitioning to Slurm or seeking to improve efficiency with the scheduler. Prerequisites: Completion of Introduction to Linux and Introduction to Shell Scripting, or prior experience with both.
