There are several different types of NVIDIA GPUs in the Nexus cluster that are available to be scheduled. They are listed below in order of newest to oldest architecture, and then alphabetically.

We do not list the exact quantities of GPU here since they change frequently due to additions to or removals from the cluster or during compute node troubleshooting. To see which compute nodes have which GPUs and in what quantities, use the show_nodes command on a submission or compute node. The quantities are listed under the GRES column.

[0] - This GPU is actually a pair of two physical cards connected over NVLink bridges. NVIDIA's provided specifications for this GPU type are for one physical card; to get these specs, we have hence doubled their advertised values.
