Nodes Overview¶
Apocrita runs a variety of different job types, and the cluster is comprised of different node types and partitions to accommodate this. Unless you have a specific technical reason, you should avoid selecting a specific node type to run your job on. Some nodes are restricted depending on the source of funding.
Hyperthreading is not enabled across the cluster. The "Threads" column within the below tables has been added for completeness.
The following nodes are open access, allowing jobs from any user.
| Open Access | Required variables | Count | Cores | Threads | RAM | Accessible RAM | Arch |
