Need more computing power?

We provide USGS scientists with access to high-performance computing (HPC) resources.

There are three on-premises USGS supercomputers housed in Sioux Falls, SD:

  • Denali is the flagship USGS supercomputer for large-scale models.
  • Tallgrass is a prototype system designed for artificial intelligence and machine learning workloads.
  • Hovenweep replaces Yeti as the workhorse USGS supercomputer for general-purpose HPC workloads.

For more information or to get started using Denali, Tallgrass, or Hovenweep, contact us at
