AI performance is not decided by GPUs alone because the network now determines how effectively thousands of accelerators can operate as one machine. Clayton Wagar, Leader of AI and High Performance Networking at Nokia, explains why congestion, resilience, optics and fabric design could matter more than adding another rack of compute.
Kevin Roof from LiquidStack explains how as GPU densities surge towards megawatt-scale racks liquid cooling, modular infrastructure and radically new data centre architectures are reshaping the future of AI infrastructure before the industry melts under its own success.
Mark Venables speaks to Pablo Ruiz Escribano from Schneider Electric about megawatt racks and liquid cooling to power accessibility, grid integration and the race to deploy AI infrastructure faster than engineering culture can adapt.
