Homa: The End of TCP for AI Clusters
signa11 · hn · 2026-10-05
An HN discussion around Stanford's Homa transport protocol, pitched as a replacement for TCP in AI clusters. Homa redesigns the transport layer for AI training traffic dominated by short messages and incast congestion, claiming major gains in tail latency over TCP and RDMA-based setups. The post links a talk video plus a Register writeup of the Stanford work.
