Meta details MetaRoCE, an RDMA transport designed for AI-scale Ethernet
Original titleMetaRoCE: A New RDMA Transport Built for AI-Scale Ethernet
AISummary
Meta designed MetaRoCE, a clean-sheet RDMA transport for AI workloads on commodity Ethernet, and is releasing its specification, reference software and compliance test suite through the Open Compute Project.
On a 64-node AMD GPU cluster running RCCL collectives, the post reports MetaRoCE delivering higher throughput and lower flow completion times than RoCEv2, with about 86% throughput maintained at 1% packet loss.
AIWhy it matters
The post explains how per-path endpoint intelligence replaces lossless fabric assumptions, with measured throughput and loss results against RoCEv2 on a 64-node AMD cluster.
