Cornelis CN5000 Deployed by U.S. Department of Energy’s National Nuclear Security Administration at Lawrence Livermore National Laboratory

System to deliver breakthrough performance, scalability, and reliability for mission-critical AI and HPC simulation workloads

WAYNE, Pa.--(BUSINESS WIRE)--Cornelis Networks, a leading provider of intelligent, high-performance networking solutions, today announced that the CN5000 is being deployed by the U.S. Department of Energy’s (DOE) National Nuclear Security Administration (NNSA) to power the 952-node “Lynx” cluster at Lawrence Livermore National Laboratory (LLNL). Chosen for the Commodity Technology Systems (CTS-2) network infrastructure refresh, in partnership with Dell Technologies, CN5000 delivers mission-critical performance for the NNSA’s Advanced Simulation and Computing (ASC) program.

CN5000 is an end-to-end, scale-out networking solution engineered to unlock the full performance potential of AI and HPC environments. Purpose-built to overcome compute underutilization and scaling bottlenecks, it delivers lossless data transfer, advanced congestion avoidance, and ultra-low latency.

“We’re pleased to partner with Cornelis on CN5000 and look forward to leveraging its performance and features to accelerate our mission-critical HPC and AI workloads,” said Matt Leininger, Senior Principal HPC Strategist at LLNL.

CN5000 is the culmination of a three-year collaboration between Cornelis and the NNSA based on requirements defined under the Next-Generation High Performance Computing Network (NG-HPCN) project. CN5000's Omni-Path architecture delivers breakthrough performance through patented congestion management, advanced link-level innovations, and proven scalability across large-scale deployments. This integrated approach ensures consistent, high-speed performance for the most demanding AI training and complex simulation workloads, giving organizations like the DOE the computational power needed for critical national security applications.

“We are excited about the launch of CN5000 and look forward to the impact of its innovations on future NNSA Commodity Technology and Advanced Technology Systems,” said Stephen Rinehart, Assistant Deputy Administrator for NNSA Advanced Simulation and Computing and Institutional R&D Programs.

“Cornelis Networks is honored to partner with the NNSA on advanced computing and simulation for the safety and security of nuclear technologies in the U.S. and worldwide,” said Rob Hays, Vice President of Public Sector at Cornelis Networks. “With CN5000, we’re helping the DOE accelerate scientific discovery and tackle complex national security challenges.”

The CN5000 end-to-end network portfolio, includes air- and liquid-cooled SuperNICs, 48-port switches, modular 576-port Director Class switches, cables, and open-source host and network management software.
