Node-Local Storage
Each compute and login node has a local storage area, accessible as /scratch and /work. On most nodes, this is a small disk (200GB-1TB), but some diskless nodes use space on /XXX-L.
Single-node slurm jobs can create temporary workspace her under the user's directory (e.g. /scratch/username/slurm_job_id).
These locations can only be accessed from the node they are on, and are subject to automatic cleanup when jobs end. If jobs end due to hardware or queuing system failures, temporary files may recoverable.
