Batch partitions (queues) defined on the Sapelo2
There are different partitions defined on Sapelo2. The Slurm queueing system refers to queues as partition. Users are required to specify, in the job submission script or as job submission command line arguments, the partition and the resources needed by the job in order for it to be assigned to compute node(s) that have enough available resources (such as number of cores, amount of memory, GPU cards, etc). Please note, Slurm will not allow a job to be submitted if there are no resources matching your request. Please refer to Migrating from Torque to Slurm for more info about Slurm queueing system.
The following partitions are defined on the Sapelo2 cluster:
| Partition Name | Time limit | Max jobs running | Max jobs able to be submitted | Notes |
|---|---|---|---|---|
| batch | 7 days | 250 | 10,000 | Regular nodes. |
| batch_30d | 30 days | 1 | 2 | Regular nodes. A given user can have up to one job running at a time here, plus one pending, or two pending and none running. A user's attempt to submit a third job into this partition will be rejected. |
| highmem_p | 7 days | 15 | 100 | For high memory jobs |
| highmem_30d_p | 30 days | 1 | 2 | For high memory jobs. A given user can have up to one job running at a time here, plus one pending, or two pending and none running. A user's attempt to submit a third job into this partition will be rejected. |
| hugemem_p | 7 days | 4 | 4 | For jobs needing up to 2TB of memory |
| hugemem_30d_p | 30 days | 4 | 4 | For jobs needing up to 2TB of memory |
| gpu_p | 7 days | 18 | 20 | For GPU-enabled jobs. |
| gpu_30d_p | 30 days | 2 | 2 | For GPU-enabled jobs. A given user can have up to one job running at a time here, plus one pending, or two pending and none running. A user's attempt to submit a third job into this partition will be rejected. |
| inter_p | 2 days | 3 | 20 | Regular nodes, for interactive jobs. |
| name_p | variable | Partitions that target different groups' buy-in nodes. The name string is specific to each group. | ||
When defining the resources for your job, you'll want to make sure you stay within the bounds of the resources available for the partition that you're using. The below table outlines the resources available per type of node, with the red values being the maximum for that corresponding partition.
| Partition Name | # of Nodes | Max Mem(GB)/Node | Max Cores/Node | Processor Type | GPU Cards/Node |
