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.
