+## Compute nodes
+
+The Engaging Cluster has several CPU-only compute nodes and GPU compute nodes.  The nodes are categorized according to partitions to control which groups have access to the nodes.
+
+See [Determining resources for your job](https://engaging-web.mit.edu/eofe-wiki/slurm/resources/) for details on selecting the nodes and resources for your jobs.  Briefly, the `sinfo` command shows the partitions where you can submit jobs and you can submit jobs to a certain partition by including `#SBATCH --partition=<partition_name>` in your sbatch script.
+
+The GPU nodes are available through the `ou_bcs_high` and `ou_bcs_low` partitions.  For more details, see the [BCS computing resources on Engaging - Slurm configuration](https://github.mit.edu/MGHPCC/OpenMind/wiki/User-guide-for-BCS-computing-resources-on-Engaging#slurm-configuration) wiki.

 ## Data storage
 
 Data can be stored under the following path: `/orcd/data/linc/`.  We will be working to create an organization strategy for the LINC project data but for now please store your data under a subdirectory (e.g. `/orcd/data/linc/<username>` or `/orcd/data/linc/<projectname>`).  There are additional locations to store your data including the use of scratch space (`/orcd/scratch/bcs/001`, `/orcd/scratch/bcs/002`, `/pool001/<username>`) which can be found under the [Storage](https://engaging-web.mit.edu/eofe-wiki/storage/) page and the [BCS computing resources on Engaging](https://github.mit.edu/MGHPCC/OpenMind/wiki/User-guide-for-BCS-computing-resources-on-Engaging) wiki.
