Job Partitions/Queues on Schooner

When you submit a job to Schooner, you must specify a partition (also called queue) for that job to run in.  The partition tells Schooner which compute nodes to use to ensure optimal job execution. Schooner has several public partitions that can be used depending on the type of job you plan on running.

Partition Name
Job Execution Time LimitDescription
32gb_20core48 hours

This partition/queue is for jobs that use multiple compute nodes (e.g., MPI parallel jobs), or jobs that fit in a single compute node, and only need up to 20 CPU cores in each node and up to ~30 GB RAM in each node.

Jobs in this partition/queue should be limited to 240 CPU cores (12 compute nodes).

This partition/queue has general-use compute nodes that each have dual Intel Xeon Haswell 10-core CPUs (20 cores total) and 32 GB RAM.

64gb_24core48 hours

This partition/queue is for jobs that use multiple compute nodes (e.g., MPI parallel jobs), or jobs that fit in a single compute node, and need 21 to 24 CPU cores in each node and/or ~31 to ~60 GB RAM in each node.

Jobs in this partition/queue should be limited to 240 CPU cores (10 compute nodes).

This partition/queue has general-use compute nodes that each have dual Intel Xeon Haswell 12-core CPUs (22 cores total) and 64 GB RAM.

normal48 hours

This partition/queue is for jobs that use multiple compute nodes (e.g., MPI parallel jobs), or jobs that fit in a single compute node, and only need up to 20 CPU cores in each node and up to ~30 GB in each node.

Jobs in this partition/queue should be limited to 240 CPU cores (12 compute nodes).

This is the default partition/queue, combining all of the compute nodes in both the 32gb_20core partition/queue and the 64gb_24core partition/queue.

large_mem48 hours

This partition/queue is for jobs that each fit in a single (but big) compute node and that need 25 to 32 CPU cores and/or ~60 to ~1000 GB RAM.

This partition/queue has Schooner's only general-use large RAM node, which has quad Intel Xeon Haswell 8-core CPUs (32 cores total) and 1024 GB (1 TB) RAM.

longjobs7 days

This partition/queue is for jobs that need to run for 2 to 7 days, specifically:

* jobs that use up to 31 compute nodes (e.g., MPI parallel jobs), or jobs that each fit in a single compute node, and that need up to 20 CPU cores in each node and up to ~30 GB in each node,

OR

* jobs that use up to 3 compute nodes (e.g., MPI parallel jobs), or jobs that fit in a single compute node, and that need 21 to 24 CPU cores in each node and/or ~31 to ~60 GB in each node.

This partition/queue has 31 general-use compute nodes:

* 28 general-use compute nodes that each have dual Intel Xeon Haswell 10-core CPUs (20 cores total) and 32 GB RAM

PLUS

* 3 general-use compute nodes that each have dual Intel Xeon Haswell 12-core CPUs (24 cores total) and 64 GB RAM.

The nodes in this partition/queue are a subset of the nodes in the normal partition/queue and other general-use partitions/queues.

largejobs48 hours

This partition/queue is for multi-node parallel jobs (e.g., MPI parallel jobs) that need either

* 241 to 6000 CPU cores/13 to 300 compute nodes, in nodes that each use up to 20 CPU cores and up to ~30 GB RAM,

OR

* 241 to 840 CPU cores/11 to 35 compute nodes, in nodes that each use 21 to 24 CPU cores and/or ~30 to ~60 GB RAM.

NOTE: Jobs of up to 240 CPU cores/12 compute nodes should be submitted to the other general-use queues, NOT to largejobs.

This partition/queue has all of the compute nodes found in both the 32gb_20core partition/queue and the 64gb_24core partition/queue.

debug30 minutes

For testing, debugging and performance benchmarking of your software, for up to 30 minutes per job on up to 3 compute nodes, specifically:

* 2 compute nodes of 20 CPU cores and 32 GB each

AND

* 1 compute node of 24 CPU cores and 64 GB each.

Almost always, jobs submitted to the debug queue start within 30 minutes of being submitted, but of course this ISN'T GUARANTEED.

debug_5min5 minutes

For very quick testing, debugging and performance benchmarking of your software, for up to 5 minutes per job on up to 3 compute nodes, specifically:

* 2 compute nodes of 20 CPU cores and 32 GB each

Almost always, jobs submitted to the debug_5min queue start within 5 minutes of being submitted, but of course this ISN'T GUARANTEED.

To specify a partition, use the following line of code in your batch script:

#SBATCH --partition=[partition name]

Example: To use the normal partition:

#SBATCH --partition=normal

Please contact us at support@oscer.ou.edu if you have questions about which partition is best for your job.
