AI Stack/Networking & interconnect

Networking & interconnect

High bottleneck

Switches, optical interconnects, NICs, DPUs, and the optics modules connecting GPUs, racks, and data centers.

A 100,000-GPU cluster behaves as a single computer or a slow disaster depending on how the network is built. Bandwidth and latency requirements are pulling optics deeper into the rack.
