[{"type":"text","content":"CoreWeave to Deploy NVIDIA Spectrum-XGS Ethernet With Scale-Across Technology\nPALO ALTO, Calif., Aug. 22, 2025 (GLOBE NEWSWIRE) -- Hot Chips -- NVIDIA today announced NVIDIA® Spectrum-XGS Ethernet, a scale-across technology for combining distributed data centers into unified, giga-scale AI super-factories. As AI demand surges, individual data centers are reaching the limits of power and capacity within a single facility. To expand, data centers must scale beyond any one building, which is limited by off-the-shelf Ethernet networking infrastructure with high latency and jitter and unpredictable performance. Spectrum-XGS Ethernet is a breakthrough addition to the NVIDIA Spectrum-X™ Ethernet platform that removes these boundaries by introducing scale-across infrastructure. It serves as a third pillar of AI computing beyond scale-up and scale-out, designed for extending the extreme performance and scale of Spectrum-X Ethernet to interconnect multiple, distributed data centers to form massive AI super-factories capable of giga-scale intelligence. “The AI industrial revolution is here, and giant-scale AI factories are the essential infrastructure,” said Jensen Huang, founder and CEO of NVIDIA. “With NVIDIA Spectrum-XGS Ethernet, we add scale-across to scale-up and scale-out capabilities to link data centers across cities, nations and continents into vast, giga-scale AI super-factories.” Spectrum-XGS Ethernet is fully integrated into the Spectrum-X platform, featuring algorithms that dynamically adapt the network to the distance between data center facilities. With advanced, auto-adjusted distance congestion control, precision latency management and end-to-end telemetry, Spectrum-XGS Ethernet nearly doubles the performance of the NVIDIA Collective Communications Library, accelerating multi-GPU and multi-node communication to deliver predictable performance across geographically distributed AI clusters. As a result, multiple data centers can operate as a single AI super-factory, fully optimized for long-distance connectivity. Hyperscale pioneers embracing the new infrastructure include CoreWeave, which will be among the first to connect its data centers with Spectrum-XGS Ethernet. “CoreWeave’s mission is to deliver the most powerful AI infrastructure to innovators everywhere,” said Peter Salanki, cofounder and chief technology officer ...
