Balakrishnan Raman, AMD and Sandeep Nagaraj, Meta present "MetaRoCE: From Spec to NIC to Open Source" live from the Santa Clara Convention Center.
As AI and distributed workloads push datacenter fabrics to their limits, Meta's answer is MetaRoCE — a multipath, out-of-order, receiver-driven protocol that treats Ethernet as inherently lossy and pushes all intelligence into the NIC. This talk traces MetaRoCE's journey from specification to silicon, showcasing its implementation on AMD Programmable NICs via reference software implementation and demonstrating how the architecture elegantly scales out within a cluster and scales across fabrics to meet diverse deployment needs.
We present real-world performance results spanning multiplane FPF topologies, tail-latency optimization, and long-distance RDMA — proving MetaRoce approach solves AI data center requirements. Finally, we present a first look at Meta's upcoming open-source release of the MetaRoCE specification, reference implementation, and compliance suites at OCP — inviting the industry to build, extend, and innovate on MetaRoCE.
