Netwerken
The fabrics that turn tens of thousands of accelerators into one machine: scale-up interconnects, scale-out networks and the optics underneath.
Veldnotities
De onglamoureuze waarheid van grote AI: het netwerk bepaalt hoeveel van uw miljardendollarcluster u daadwerkelijk kunt benutten. De strijd om te volgen is koperimperium versus open Ethernet — NVIDIA's privéfabrieken tegen de gedeelde standaard van iedereen.
