Minerva uses LSF (Load Sharing Facility) to schedule jobs. This section gives details of the queues and scheduling policies on Minerva.

 

Queues

The command to check the queues is “bqueues”.
To get more details about a specific queue, type “bqueues -l <queue name> Eg.,

bqueues -l premium

Current Minerva Queues:

Queue	Description	Max Walltime	Defaults (Mem/core|Walltime)
premium	Normal submission queue	144 hrs	3000MB | 5hrs
express	Rapid turnaround jobs	12 hrs	3000MB | 1hr
interactive	Jobs running in interactive mode	12 hrs	3000MB | 2hrs
long	Jobs requiring extended runtime	336 hrs	3000MB | 5 hrs
gpu	Jobs requiring gpu resources	144 hrs	3000MB | 5 hrs
private	Jobs using dedicated resources	unlimited	3000MB | 5hrs
others	Any other queues are for testing by the Scientific Computing Group	N/A	N/A

All jobs must specify project using the -P bsub option

If -P option is not specified, job will be immediately terminated.

 

Policies

LSF is configured to do “first fit” backfill. Backfilling allows smaller, shorter jobs to use otherwise idle resources.

In certain special cases, the priority of a job may be manually increased upon request. To request priority change you may contact MSSM Scientific Computing Support at hpchelp@hpc.mssm.edu. We will need the job ID and reason to submit the request.
