Eridu flags east‑west GPU traffic

- Eridu posted that legacy cloud architectures break down for large AI workloads and that GPU synchronization patterns are shifting traffic to east‑west GPU links. - The thread urges clean‑sheet designs focusing on GPU‑to‑GPU networking, not traditional north‑south cloud calls, to avoid bottlenecks. - This reframes network design for large model training and inference at scale, emphasising locality and new synchronization primitives.
