Tempest is a high performance computing (HPC) research cluster at MSU and the largest supercomputer in Montana. Tempest features powerful high-memory compute systems, GPUs, a fast storage system, support for long-running workloads, and an interactive web interface with graphical desktops, RStudio, JupyterLab, file transfer,  and easy workload submission functionality . RCI provides training and full support for the Tempest HPC system. Tempest is available via a buy-in model with a free access tier for all MSU researchers and instructors.

Technical Specifications 

Tempest is an HPC cluster consisting of EPYC X86 CPU and Nvidia GPU nodes. In total, Tempest currently has 12,264 logical CPU cores, 55.9TB of ECC memory, 26 Nvidia A40 GPUs, 14 Nvidia A100 GPUs, and 12 Nvidia H100 GPUs. For storage, Tempest currently has 600TB of all-flash high-speed storage. Tempest components are interconnected by 100/50/25Gb Ethernet with RDMA.

Getting Access

Tempest has two tiers of access: a free-access tier, and a buy-in tier

Free Access Tier

Each PI or class at MSU is eligible for priority access to 256 CPUs, 1024GB of memory, and 2 GPUs (of which up to 1 can be an A100 GPU) for MSU research or instruction. In addition to this limited priority acces, all MSU researchers also recieve fairshare access to a portion of Tempest and premtible access to any idle resoruces. Availability of free tier resources is subject to change.

Buy-In Tier

Those who buy-in to Tempest receive resource allocations in addition to the free tier allocation. Buy-in supports the maintenance of the cluster. Each buy-in group receives absolute priority access to a resource allocation commensurate to their level of contribution in addition to the free access tier. Contributors also have the ability to "burst" priority workloads to 200% of their allocation (up to a $30,000 value in additional resources). Additionally, all Tempest users are able to run unlimited "unsafe" and "legacy" jobs on any resources not being used for priority jobs.

Contributors also have the option to optimize their buy-in for either A40 or A100 GPUs. Those including tempest funding in grant proposals should list it as a line item under contracted services in the grant budget.

Over $30,000 resource allocation rates differ.
