Slurm Partitions
The cluster is organized into logical groups called partitions, each defined by specific resource constraints and user access limits. Nodes can belong to multiple partitions; for example, the medium and long partitions include a subset of the nodes available in the short partition. This arrangement ensures that long-running jobs in the medium and long partitions do not block jobs with shorter time limits in the short partition.
Selecting the most appropriate partition for your job will help maximize efficiency and reduce time waiting in the queue.
To view state of nodes in the partitions use the sinfo command as described in Slurm Commands.
Parition List
| Partition | Time Limit | RAM Limit | Access Limitations | Notes |
|---|---|---|---|---|
| build | 2 hours | N/A | Open to all faculty sponsored cluster users | This is a special use partition for installing local packages in your home directory (e.g. R libraries), and running quick tests. These nodes contain the oldest CPU types used in the cluster, which ensures that any software compiled on the build partition will work across all other nodes in the cluster. |
| short | 12 hours | 30GB (30000MB) | Open to all faculty sponsored cluster users | The short partition has access to the highest number of compute nodes. If you're able to keep the length of your job steps under 12 hours, this is the best partition to use. |
| medium | 7 days | 30GB (30000MB) | Open to all faculty sponsored cluster users | |
| long | 45 days | 30GB (30000MB) | Open to all faculty sponsored cluster users | |
| largemem | 45 days | Unlimited | Open to all faculty sponsored cluster users | The largemem partition only contains a subset of the nodes used in the short, medium and long partitions. Only use largemem if need more than 30GB/job step, otherwise you will be limiting the resources available for your job. |
| gpu | 14 days | N/A | Open to all faculty sponsored cluster users | Each node has 2 Tesla V100 GPUs. The number of GPUs must be specified with --gres=gpu:<GPU number> |
| student | 14 days | N/A | For students in Stat classes that include cluster computing in the curriculum | The student partition is limited to a small number of older cluster nodes. If you have a sponsored cluster account, do not use the student partition. |
| faloorum | No limit | Unlimited | Access limited to Adrian Raftery's group. | See the bayespop wiki for details on the faloorum partition. |
