The resources provided by OIT HPSC includes three clusters, two for open research and one for processing sensitive information. Each cluster has a Lustre file system with petabyte scale storage capacity. These resources can be used by faculty and student researchers and for academic coursework.

ISAAC Legacy cluster for Open Research
228 compute nodes of various types including these noteworthy types:
2 Data Transfer Nodes with 40 Gb/s bandwidth and Globus
ISAAC Secure Enclave cluster
60 compute nodes, 2 nodes with 2x NVIDIA V100S GPUs
2,848 CPU cores
Nodes with 192 gigabytes of memory
1.7 petabytes of Lustre storage in /lustre/sip
1 Data Transfer Node with 10 Gb/s bandwidth and Globus
Details of the types of compute nodes available that make up each cluster is listed in the System Overview page for each cluster (listed in menus on the left).
Node Naming Conventions
The following table summarizes the meaning of the alphabetic portion of the nodenames, which are generally composed of the manufacturer codename, plus an additional letter in some instances for special node types such as GPU or Bigmem:
Intel Cascade Lake Refresh
Intel Cascade Lake Refresh Bigmem
Intel Cascade Lake Refresh with NVIDIA Volta 100 GPU
Intel Ice Lake
Intel Ice Lake with NVIDIA Ampere 16 GPU
Intel Ice Lake Bigmem
Intel Ice Lake Platinum
Intel Ice Lake Platinum with NVIDIA Ampere 40 GPU
Intel Sky Lake
Intel Sky Lake with NVIDIA Volta 100 GPU
Intel Sapphire Rapids Platinum with NVIDIA Hopper 100 GPU
Table 1: Nodename Prefixes
The meaning of the numerical portion of the node names varies by cluster. For the ISAAC Legacy cluster (3 digit suffix), the numerical portion is incremented and assigned to consecutive nodes of the same type as they are deployed. Consecutively numbered nodes are in many cases located in the same rack and share a common Infiniband switch, but there is no guarantee of this. For the SIP and NG clusters (4 digit suffix), the first digit is a row number, the second is a rack number within the row, and the final two digits are a rack unit number within the rack. In all cases for these two clusters, nodes will be closest together in the Infiniband fabric when their node numbers are most similar.
