Ultra Ethernet: When "Best Effort" Isn't Good Enough for AI I've spent the better part of two decades watching networking technologies come and go. Most of them promised revolution and delivered incremental improvement.

#UltraEthernet for Next Generation #AI and #HPC workloads

Multiple AI Scale-Up Options Emerge As data center infrastructures adapt to evolving workloads, parts of Ethernet can be found in scale-up approaches.

Actual advanced #kubecom topics I want to chat about & for real build great shit around:
#wasm (& other side of the pipe webworker systems)
#ultraethernet

#NANOG is one of the greatest conferences, a whole wide world of internetworking. NANOG 95 videos dropping now.

Quite ambitious & lovely effort to build a "XDP2" that can target multiple systems (including XDP?), & Tom's been building an #UltraEthernet impl atop it. Talk is 50%+ UltraEthernet.

Ultra Ethernet Consortium (UEC) Launches Specification 1.0 Transforming Ethernet for AI and HPC at Scale - Ultra Ethernet Consortium SAN FRANCISCO, Calif. — [EMBARGOED UNTIL JUNE 11, 2025] – The Ultra Ethernet Consortium (UEC) today announces the release of UEC Specification 1.0, a comprehensive, Ethernet-based communication stack ...

#ICYMI
The #UltraEthernet Consortium released UEC Specification 1.0 on June 11, 2025.
Now we (the #Ethernet industry) have to go from the spec to useful product (pressure is on).

AMD Vulcano 800G NIC Coming As AMD Outlines its UALink and UEC Scale Plans AMD’s Pensando came with some codenames that I really like. The AMD Pollara 400 AI NIC is shipping, and the AMD Vulcano 800G NIC is preparing for a next-generation launch. AMD is focusing on UltraEthernet as well as UALink for its scale out and scale up stories, and the NICs matter for those applications. AMD […] The post AMD Vulcano 800G NIC Coming As AMD Outlines its UALink and UEC Scale Plans appeared first on ServeTheHome.

New Data Center Protocols Tackle AI UALink scales up, while Ultra Ethernet scales out.

Two new protocols — UALink and Ultra Ethernet — aim to address deficits in current scale-up and scale-out communications. UALink is a completely new scale-up protocol, while Ultra Ethernet builds on Ethernet for scale-out. semiengineering.com/new-data-cen...
