NVIDIA Spectrum-X Ethernet 如何改写 Giga-Scale AI 网络规则
Giga-Scale AI and the Ethernet Evolution: How Spectrum-X Ethernet Rewrites the Rules
面对分布在数十万块 GPU 上的分布式模型训练，传统通用 Ethernet 已成为首要性能瓶颈。NVIDIA 称 Spectrum-X Ethernet 针对这一 Giga-Scale AI 场景重构了网络规则，但文中未披露具体的吞吐、延迟或加速倍数数据。

The massive growth of generative AI has fundamentally altered data center design. As distributed model training scales to span hundreds of thousands of GPUs, the scale-out network connecting these nodes has emerged as a first-order performance bottleneck. For decades, traditional off-the-shelf Ethernet has been the undisputed king of enterprise and cloud networking. It is cheap, standardized…
