Tensor-Parallel Inference Hits Capacity Limits on NVLink
Where tensor-parallel inference hits the NVLink wall 2026-05-31 · GPU / distributed systems Tensor parallelism splits each layer across GPUs, so every forward pass pays for an all-reduce over the network fabric. On a single node that fabric is NVLink/NVSwitch — and 4× H100 and explains where the wal
