2.3.1 Redwood Job Scheduling Policy
Job Control
Jobs will be controlled through the batch system using Slurm.
- Node sharing. No node sharing.
- Allocations. No allocation controls.
- Best effort to allocate nodes of same CPU speed.
- Max time limit for jobs will be as outlined in the QOS definitions below.
- Scheduling is set based on a current highest priority set for every job, plus backfill.
- Fairshare boost in priority at user level. Minimal boost to help users who haven't been running recently. Our Fairshare window is two weeks.
- Small relative to time small short jobs are given a boost for length of time in the queue as it relates to the wall time they have requested.
- Reward for parallelism. Set at the global level
- Special Reservations - upon request.
- Partitions
