ServerMO guide optimizes AI cluster networks with RoCEv2

By PulseAugur Editorial · [1 sources] ·

ServerMO has released a guide detailing how to optimize AI cluster networks using the Multi-Rail RoCEv2 standard. The guide addresses issues like packet drops and hash collisions that can stall GPU training. It recommends bypassing the OS kernel with RDMA, implementing lossless PFC with deadlock watchdogs, and using Multi-Rail PCIe affinity to directly link NICs to GPUs. AI

IMPACT Provides technical guidance for improving the efficiency of AI training infrastructure.

RANK_REASON The cluster describes a technical guide for optimizing network infrastructure, which falls under tooling.
