Distributed vLLM inference stacks detailed for 2026

This technical guide explores building distributed vLLM inference stacks for large language models, addressing the limitations of single-GPU serving. It details techniques like Tensor Parallelism for model sharding across nodes and RDMA (RoCE v2) for reducing inter-node latency. The guide also covers practical implementation paths, including on-premise clusters with AMD hardware and cloud deployments using Hugging Face Jobs with H200 GPUs, as well as vLLM's Semantic Router Fusion for multi-model serving.
