Google's unit of training: thousands of TPUs behind optical circuit switches.
您正在查看一条系统记录：一台组装完成的机器——一台服务器或整个机架——包含其内部组件及部署位置。
Google scales TPUs in pods — 4,096 chips (v4), 8,960 (v5p), 9,216 (Ironwood) — wired by inter-chip interconnect in a 3D torus and reconfigured through optical circuit switches that route around failures without touching a cable. Gemini trains across multiple pods over the Jupiter network; the pod, not the server, is Google's hardware product.
