Ultra Ethernet Consortium
- throw0101b 3y agoFrom the FAQ: -- What are the goals and mission of Ultra Ethernet Consortium (UEC)? Deliver a complete architecture that optimizes Ethernet for high performance AI and HPC networking, exceeding the performance of today’s specialized technologies. UEC specifically focuses on functionality, performance, TCO, and developer and end-user friendliness, while minimizing changes to only those required and maintaining Ethernet interoperability. Additional goals: * Improved bandwidth, latency, tail latency, and scale, matching tomorrow’s workloads and compute architectures. * Backwards compatibility to widely-deployed APIs and definition of new APIs that are better optimized to future workloads and compute architectures. -- Basically going after Infiniband (IB). While Ethernet and IB seem to have equal roughly number of system in the Top 500 (Category > Interconnect Family): * https://www.top500.org/statistics/list/ https://www.top500.org/statistics/list/ The majority of the Top 100 and 200 seem to have IB: * https://thelinuxcluster.com/2021/07/08/a-relook-at-infiniband-and-ethernet-trends-on-top500/ https://thelinuxcluster.com/2021/07/08/a-relook-at-infiniban... * https://www.nextplatform.com/2021/07/07/the-eternal-battle-between-infiniband-and-ethernet-in-hpc/ https://www.nextplatform.com/2021/07/07/the-eternal-battle-b... Once you get to the slower (older?) systems Ethernet starts being the majority.
