| t1standard | 123        | 4 days       | 3+    | Default, always uses 3 nodes. If you need less than 3 nodes use the small partitions.                                         | General-purpose partition                     |
| t2small    | 123        | 4 days       | 1-2   | [Tier 2](/uaf-rcs-hpc-docs/community-condo-model/community-condo-model.md#tier2) users only. Increased priority and walltime. | Tier 2 version of t1small                     |
| t2standard | 123        | 7 days       | 3+    | [Tier 2](/uaf-rcs-hpc-docs/community-condo-model/community-condo-model.md#tier2) users only. Increased priority and walltime. | Tier 2 version of t1standard                  |

| Name     | Node Count | Max Walltime | Cores | Other Rules | Purpose                                               |
| -------- | ---------- | ------------ | ----- | ----------- | ----------------------------------------------------- |
| analysis | 3 BigMem   | 4 days       | 1-7   | Shared node | For serial pre- and post-processing                   |
| bio      | 3 BigMem   | 14 days      | 1-7   | Shared node | For high memory, low CPU jobs                         |
| transfer | 1          | 1 day        | 1     | Shared node | Copy files between archival storage and scratch space |

Selecting a partition is done by adding a directive to the job submission script such as `#SBATCH --partition=t1standard`, or on the command line: `$ sbatch -p t1standard`

**Please note**: When running a job in the analysis or bio partition the --mem SBATCH directive **must** be set as to not affect other users' work. Adding: `#SBATCH --mem=214G` is the RCS recommendation

Anyone interested in gaining access to the higher-priority [Tier 2](/uaf-rcs-hpc-docs/community-condo-model/community-condo-model.md#tier2) partitions (t2small, t2standard) by subscribing to support the cluster or procuring additional compute capacity should contact <uaf-rcs@alaska.edu>.
