Play the recording: Scaling Out and Across: Networking Innovations for Giga-Scale AI Systems

  • Why: The roadmap talk for where datacenter fabrics are heading as clusters go from hundreds of thousands toward millions of GPUs — ultra-high-radix switching, co-packaged optics, and multi-site scale-across are all in the PM's lane.
  • What: An unveiling of NVIDIA's networking portfolio for giga-scale AI: next-generation Quantum-X InfiniBand and Spectrum-X Ethernet platforms with co-packaged optics, ultra-high-radix switches, and accelerator-optimized SuperNICs, aimed at training foundation models, real-time inference, and federated AI factories across sites. (from abstract only)
  • How: Abstract-level mechanisms only: co-packaged optics on switch platforms, SuperNIC-optimized host interfaces, and fabric designs targeting predictable latency and lossless throughput across sites.
  • Where applicable: NVIDIA product roadmap — expect heavy positioning, but it is the clearest signal of the next fabric generation (radix, optics integration, scale-across) and worth attending for that alone.
