Lawrence Livermore National Laboratory in California has entered production for the Lynx supercomputing cluster, a new high-performance computing system designed to support nuclear weapons simulations and other key national security workloads.
The system is part of the National Nuclear Security Administration’s (NNSA) Commodity Technology Systems-2 program, an effort to provide advanced computing resources across the nuclear security enterprise, according to Cornelis Networks’ press release Tuesday.
Cornelis spoke on its partnership with NNSA and its future deployment of Lynx in August 2025.
Lynx consists of 952 computer nodes connected through Cornelis’ networking technology, which is designed to move data efficiently across large-scale computing environments. The system will support the NNSA’s Advanced Simulation and Computing program, which relies on sophisticated modeling and simulation tools to assess the safety, security and reliability of the U.S. nuclear weapons stockpile without underground nuclear testing.
“Lynx represents an important milestone in NNSA’s work to evaluate and deploy next-generation high-performance computing technologies for mission use,” Stephen Rinehart, Assistant Deputy Administrator for the NNSA’s Office of Advanced Simulation and Computing, said in the release. “The system builds on NNSA’s Next-Generation High Performance Computing Network effort and strengthens the computing ecosystem supporting future ASC workloads.”
Lynx joins a growing conglomerate of computing systems at Livermore, including the El Capitan supercomputer. While El Capitan is intended for the most demanding computational workloads, Lynx is expected to serve as a platform for a broad range of simulation and artificial intelligence applications supporting NNSA missions.
Cornelis, which came out of Intel in 2020, said the deployment demonstrates growing demand for specialized networking technologies in large-scale government and scientific computing environments.
