## AI overview

Cornelis and AMD launched a program to design and validate HPC and AI-for-science systems combining AMD EPYC CPUs and Instinct GPUs with Cornelis networking, sold through customers' preferred OEMs and integrators. A production example is GWDG's EMMY P4 supercomputer, with about 300 dual-socket EPYC 9745 nodes connected by a CN5000 Omni-Path fabric. Cornelis says CN5000 is qualified on EPYC 9005 platforms across more than 25 configurations and now qualified with Instinct MI350X GPUs. The text reports Cornelis's application results: STAR-CCM+ scaled to 8.99x across eight nodes, while CN5000 averaged 20% higher throughput than NVIDIA NDR InfiniBand on 132 CONVERGE workloads at four nodes; these results were not independently audited. CN6000, an 800G adapter, is being validated with EPYC 9006 and next-generation Instinct platforms. OEM systems pairing CN6000 with EPYC 9006 are expected from Q1 2027.
