分布式 AI 训练如何改变数据中心之间的网络
Google、微软、AWS、Meta 等已把大模型训练扩展到多个数据中心:Google 称 Gemini 采用跨集群同步训练,微软把威斯康星与佐治亚的 AI 数据中心连成一台分布式 AI 超级计算机,AWS 跨广域连接集群供 Anthropic 训练 Claude。Cisco 估计如今训练模型可能需要数万块 GPU 的集群,Epoch AI 预计到 2030 年最大单次前沿训练耗电可达 4-16GW;Cisco 建模显示分布式 AI 部署的聚合带宽需求约为传统 DCI 基线的 14 倍。
ives hyperscalers and datacenter operators the flexibility to add compute where power and space are available, while still treating multiple sites as part of the same training infrastructure.
