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](../../community-condo-model/community-condo-model#tier2) partitions (t2small, t2standard) by subscribing to support the cluster or procuring additional compute capacity should contact [uaf-rcs@alaska.edu](mailto:uaf-rcs@alaska.edu).
