PyTorch Conference poster to break down KV cache offloading: when CPU beats shared storage

PyTorch · x · 2026-10-20

PyTorch announced that Bongwoo Bak of Moreh will present a poster, "Where the Blocks Live," at PyTorch Conference North America (San Jose, Oct 20-21). It covers how vLLM offloads KV cache to CPU or storage when GPU memory fills up, and how llmd tracks every cache block to route requests to their cache — showing when CPU offloading suffices and when shared storage pays off. Registration runs up to $999 ($249 academic).
