Current Configurations on Finkel:¶
- Governance model for deciding what changes to make for the lab
- Josh Asuncion will coordinate with CETS on any changes that are needed
- Number of shards per GPU
- There are a total of 8 shards available on finkel.seas.upenn.edu, 4 per GPU.
- Each shard is the smallest unit. You only need to request a shard to run jobs on a GPU. Jobs which do not request a shard can run (using CPU/memory but not a GPU) when all of the shards have been claimed.
- Estimate for the smallest typical job that users would run is 12GB. On a single L40S with 48GB that would be 4 x 12GB shards per card, so 8 of those jobs could fit simultaneously on Finkel. Currently configured is 8 total, 4 per GPU card.
- There are a total of 8 shards available on finkel.seas.upenn.edu, 4 per GPU.
- Maximum time limit per job
- There is a 14 day time limit on any job.
- Maximum number of jobs per user in queue / running
- No user can have more than 100 jobs at once in the queue.
- Scratch space management
- There is a tool which automatically removes files older than 21 days from the
/scratchdirectory.
