Hi​gh Performance Computing

Nuclear Science User Facility (NSUF) High Performance Computing (HPC) resources offered through Idaho National Laboratory provide scientific computing capabilities to support efforts in advanced modeling and simulation. These resources support a wide range of research activities, including performance of materials in harsh environments (such as the effects of irradiation and high temperatures), performance of existing light water and advanced nuclear reactors, and multiscale multiphysics analysis of nuclear fuel performance.

INL HPC computing resources are available to industry, universities, national laboratories, and federal agencies to support research and development. Access is generally granted for research related to the DOE Office of Nuclear Energy and INL’s mission focusing on nuclear energy development, workforce development, and education.


  • Sawtooth: an HPE SGI 8600-based system with 99,792 cores, 395 TB of total memory high-speed InfiniBand EDR interconnect network, high-speed storage, and 0.56 petaflops of GPU capabilities. The current LINPACK rating for Sawtooth is more than six (6) petaflops from both CPUs and GPUs.
  • Lemhi: a Dell PowerEdge distributed memory system with 20,160 cores, 94 TB of total memory, Omni-Path interconnect network, and high-speed storage.  The LINPACK rating for Lemhi is 1.002 petaflops.
  • ​Hoodoo: a Lambda Hyperplane deep learning distributed memory system with 44 NVIDIA A100 Tensor Core GPUs and 7.2 TB of total memory dedicated to machine learning applications. Hoodoo provides a maximum GPU performance of 429 teraflops double precision or 858 teraflops single precision.​
