Cornelis, a provider of high-performance networking solutions, today announced the successful deployment of the “Lynx” supercomputing cluster at Lawrence Livermore National Laboratory (LLNL).
The 952-node Lynx cluster, featuring Dell PowerEdge servers, Intel® Xeon® processors, and the Cornelis CN5000 Omni-Path fabric, is part of the National Nuclear Security Administration’s (NNSA) Commodity Technology Systems (CTS-2) program. It will provide additional production capability for NNSA’s Advanced Simulation and Computing (ASC) program and NNSA’s broader national security missions.
“We are excited to see the Cornelis CN5000 400G network come to life at Lawrence Livermore National Laboratory,” said Matt Leininger, Senior Principal HPC Strategist at LLNL. “The collaboration between NNSA’s ASC program and Cornelis has been rooted in a shared commitment to advancing high-performance computing. Lynx reflects the results of that public-private R&D investment and will support the modeling, simulation and analysis capabilities that underpin the modern NNSA complex.”
Lynx is a key computing infrastructure investment for NNSA and is being integrated into LLNL’s high-performance computing environment, where it will support production modeling, simulation, and analysis for national security.
“Lynx represents an important milestone in NNSA’s work to evaluate and deploy next-generation high-performance computing technologies for mission use,” said Stephen Rinehart, Assistant Deputy Administrator for the NNSA’s Office of Advanced Simulation and Computing. “The system builds on NNSA’s Next-Generation High Performance Computing Network effort and strengthens the computing ecosystem supporting future ASC workloads.”
The Cornelis CN5000 fabric at the heart of Lynx utilizes the Omni-Path architecture, providing low-latency, lossless and congestion-free communication to maximize compute performance and efficiency for today’s HPC and AI workloads.
“The successful deployment of Lynx at LLNL marks an important milestone for CN5000 as a production-ready network for the most demanding and mission-critical computing environments,” said Brad Haczynski, Chief Commercial Officer of Cornelis. “With Lynx now in production in one of the world’s most advanced computing facilities, we have demonstrated that our CN5000 400Gbps solution is ready for broad commercial, academic, and government adoption. We look forward to CN5000 delivering the performance and price-performance organizations need to accelerate their HPC and AI initiatives.”
