Please send in a ticket requesting to be added if it is your first time using the AI cluster. You will need to be involved in research with a CS faculty member.

Feedback is requested. Find us in the Slack ai-cluster channel (channel ID: C02KW3M0BDK).

Summary of nodes installed on the cluster:

We like the alphabet, so we have compute node groups for just about every letter in it.

• "a" series: 3 nodes, each with 64 CPU threads, 192GB RAM, four RTX2080ti GPUs
• "aa" series: 2 nodes, each with 32 CPU threads, 32GB RAM, four RTX2080 GPUs
• "b", "d", "e", "k", "r" series: 15 nodes, each with 64 CPU threads, 512GB RAM, four A40's
• "c" series: 1 node with 48 CPU threads, 64GB RAM, two A30's
• "f" & "j" series: 6 nodes, each with 32 CPU threads, 128GB RAM, four A40's
• "g" & "q" series: 4 nodes, each with 96 CPU threads, 1TB RAM, eight L40S GPUs
• "h" series: 1 node with 96 CPU threads, 1TB RAM, four H100 SXM GPUs
• "l" series: 1 node with 256 CPU threads, 1.5TB RAM, six H100 PCI GPUs
• "m" series: 3 nodes with 128 CPU threads, 1.5TB RAM, no GPU's
• "n" series: 1 node with 96 CPU threads, 1.5TB RAM, four H100 SXM GPUs
• "t" series: 5 nodes with 48 CPU threads, 512GB RAM, four L40S GPUs

• all compute nodes:
  • Each node has a /local space for times when it's beneficial to not write over NFS. Space in /local varies from node to node. Please try to clean up when you're done.
  • Home directories and project space are mounted over NFS. Default quota for home directories is 50GB, but it may be increased as needed with permission.
  • Research groups may additionally be allocated project space that exists outside the home directory quota on different storage servers, for collaboration and shared storage.

• ai-storage1:
  • 63T total storage
  • uplink to cluster network: 100G
  • /home/<username>
    • 50G quota per user.

• ai-storage2:
  • 63T total storage
  • uplink to cluster network: 100G
  • /net/scratch: Create yourself a directory /net/scratch/$USER. Use it for whatever you want.
  • Eventually data will be auto deleted after X amount of time. Maybe 90 days or whatever we determine makes sense.

• ai-storage3:
  • zfs mirror with previous snapshots of ai-storage1 and ai-storage4.

• ai-storage4:
  • 70TB total storage
  • uplink to cluster network: 100G
  • /net/projects:
    • Idea would be to create a dataset with a quota for people in a collaboration group to use.
    • Normal LDAP groups that you are used to and available everywhere else would control access to these directories. e.g. jonaslab, sandlab

• peanut-storage1:
  • 273TB total storage
  • uplink to cluster network: 100G fiber
  • /net/bulk:
    • A nice place for large datasets that either don't change much, or are being used and re-used a lot.
  • /net/archive:
    • A place to keep data from projects2 that isn't actively being worked on.

• peanut-storage2:
  • 546TB total storage
  • uplink to cluster network: 100G fiber
  • backups from peanut-storage3 and peanut-storage4

• peanut-storage3:
  • 224TB total storage
  • uplink to cluster network: 100G fiber
  • /net/projects2:
    • Even more project space for your projects that you can put your projects in.

• peanut-storage4:
  • 28TB total storage
  • uplink to cluster 100G fiber
  • instructional storage for Peanut Cluster (NOT research)
