​​​High-Performance Computing

INL’s High-Performance Computing (HPC) resources provide scientific computing capabilities to support the lab’s efforts in advanced modeling and simulation. The HPC data center supports a wide range of research activities, including performance of materials in harsh environments (including the effects of irradiation and high temperatures), modeling of geomechanical changes in subsurface flow, performance of advanced gas-cooled nuclear reactors, and multiscale analysis of nuclear fuel performance.  Falcon, an SGI ICE-X system, is the current flagship machine. It is a distributed memory system with 34,992 cores, 121 TB of memory and a LINPACK rating of 1,088 TFlops.  Lemhi, our secondary machine, is also a distributed memory system with 20,160 cores, 94 TB of memory, and a LINPACK rating of 1,025 TFlops.  Other smaller systems provide specialized services.
