About HPC
INL’s HPC resources provide scientific computing capabilities to support efforts in advanced modeling and simulation. These resources support a wide range of research activities, including multiscale multi-physics performance analysis of nuclear fuel, materials in harsh environments, and existing light water and advanced nuclear reactors.
INL HPC computing resources are available to industry, universities, national laboratories and federal agencies to support published and openly available research and development. Access is generally granted for research related to the DOE Office of Nuclear Energy and INL’s mission areas.
Current Systems:
Sawtooth: 2020 to Present
Sawtooth was made available to users in March 2020 and features 2,079 compute nodes. Each node is equipped with 48 cores and 192 GB of memory. Additionally, select nodes come with 4 NVIDIA V100 GPUs and an extra 192 GB of RAM, totaling 384 GB of memory per such node. In aggregate, Sawtooth offers a total memory capacity of 404 TB.
Hoodoo: 2021- Present
Hoodoo with over 400 teraflops of performance. Hoodoo is a Lambda Hyperplane deep learning distributed memory system with 44 NVIDIA A100 tensor core GPUs and 7.2 TB of total memory. The system provides a maximum performance of 429 TFlops double precision or 858 TFlops single precision.
Bitterroot: 2024-Present
Bitterroot was made public to users on June 17, 2024. It has over 2 Petaflops of performance and has over 43,000 cores. It is a 43008-core Dell Commodity Technology Systems-2 (CTS-2) with 384 total nodes. Bitterroot has 90 TB of total memory.
Retired Systems:
Lemhi: 2019-2025
Lemhi, along with Bitterroot and Wind River (coming soon), are supercomputers at INL with an Omnipath (OPA) interconnect. Lemhi became available to users in February 2019. Each node had 192 BG of RAM, 40 cores per node, and 94.5 TB of total memory. Lemhi was decommissioned in January 2025.
Falcon: 2017-2022
Falcon was INL’s flagship cluster, delivering over 1 petaFLOPS of performance. Installed in the fall of 2014, it offered approximately twice the performance of our previous large cluster, Fission, for most applications. Falcon was an SGI ICE-X distributed memory system. In 2017, Falcon underwent expansion and upgrades. On March 31, 2022, INL decommissioned the Flacon cluster and transitioned it to the Idaho State Board of Education.
Fission: 2011-2017
Fission was deployed in 2011 with 64 GB of RAM per node and a Commodity 1U server. It became available to users in 2011 and was decommissioned in 2017.
Future Systems:
Wind River
Coming soon! Stay tuned for more information about our newest system, Wind River. It arrived at Idaho National Lab on September 30, 2024. We are working hard to get it ready for our users!
Teton
Coming soon! Stay tuned for more information about our newest system, Teton.
