In the high-stakes world of High-Performance Computing (HPC) and AI, the network is often the unsung bottleneck. While CPUs and GPUs grab the headlines, the “plumbing” that connects them determines whether a cluster hums or stutters.<\/p>\n
During ASI\u2019s recent Technology Summit, Cornelis Networks<\/strong>\u2014detailed how they are outperforming traditional InfiniBand with Omni-Path and preparing for a future with Ultra Ethernet<\/strong>.<\/p>\n Cornelis isn’t a new player; it\u2019s a specialized team with a deep pedigree. By combining Intel\u2019s Omni-Path<\/strong> technology with intellectual property from Q-Logic<\/strong> and Cray\u2019s Aries<\/strong> interconnects, Cornelis has built a fabric designed from the ground up for one thing: maximizing application performance.<\/p>\n Today, the company is shipping its second-generation product, the CN5000 (400Gbps)<\/strong>, with a roadmap that leads directly into the emerging Ultra Ethernet standard.<\/p>\n While many focus on “line rate” (how much data moves), Cornelis argues that for parallel processing, Latency<\/strong> and Message Rate<\/strong> are the true kings.<\/p>\n How does Cornelis achieve these numbers? It comes down to a few architectural “moats”:<\/p>\n Cornelis is not just maintaining its current lead; it is evolving toward total ecosystem compatibility.<\/p>\n “We will deliver the best performing standard Ultra Ethernet solution… but if it’s Cornelis talking to Cornelis, you get even better performance.”<\/p>\n One of the most impressive engineering feats discussed was their Director Class Switch<\/strong>. By utilizing a “midplane-less” design\u2014where horizontal spine blades plug directly into vertical leaf blades\u2014Cornelis has shrunk the equivalent of 36 rack units of switching into just 17 rack units<\/strong>. This results in a 33% power saving and significantly lower TCO for large-scale deployments.<\/p>\n Cornelis Networks is positioning itself as the “open” alternative to proprietary interconnects. By upstreaming their software to the Linux kernel and leading the charge with LibFabric<\/strong>, they are ensuring that moving to a higher-performance network doesn’t require rewriting a single line of application code.<\/p>\n As AI models grow and HPC simulations become more complex, the industry is moving away from “good enough” networking. With a roadmap tied to Ultra Ethernet and a current performance lead over InfiniBand, Cornelis is a name every data center architect should have on their radar.<\/p>\n Cornelis Customer Webinar \u2013 ASI Technology Summit<\/strong><\/a><\/p>\nA Heritage of Speed: From Intel to Independence<\/strong><\/h5>\n
