OnlineInference · x · 2026-09-17
CoreWeave announced the bring-up of multi-rack NVIDIA Vera Rubin NVL72 clusters — each rack packs 72 Rubin GPUs, 36 Vera CPUs, NVLink 6 fabric, and 45°C liquid cooling, with hundreds of GPUs networked into one scale-out system for training, inference, and agentic AI workloads. The blog details multi-rack engineering pitfalls: straggler GPUs, marginal network links hurting collectives, cooling anomalies, and config consistency across NVLink domains.
