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):

The majority of the Top 100 and 200 seem to have IB:

Once you get to the slower (older?) systems Ethernet starts being the majority.
