DeepEP + RoCE Doesn't Work, Warns Engineer Rerunning Benchmarks
TheZachMueller · x · 2026-09-03
A short but concrete lesson: don't pair DeepEP (DeepSeek's open-source MoE communication library) with RoCE (RDMA over Converged Ethernet) — the author's "Not even once" signals how bad the experience was, and they are rerunning benchmarks to verify the impact.
A direct warning for teams deploying MoE training or inference communication stacks over Ethernet.
