vsched is used to schedule both parallel and serial work, to all of the various
node types.
- Each running job has exclusive access to the nodes assigned. Once your job is
running and you are assigned a node or several nodes, you have exclusive access
to them. There is no sharing; you have 100% of the nodes you've acquired.
- Scheduling is first-in, first-out, with backfilling.
- Whether you submit from a Windows or Linux login node is irrelevant.
