AI Infrastructure Rebuild

AI infrastructure is moving from chip performance to system-level competition.

Topic direction
Why watch

The real competition is shifting from single-chip speed to rack, network, memory, power, packaging, protocol, software stack, and deployment economics.

Current read

The next infrastructure boundary will be decided by the coupled system: accelerator, NIC, switch, protocol, memory locality, runtime, and operations.

Research

From Clos to ZCube

Topology research shows that AI clusters may need search-shaped fabrics, not only symmetric scale-out.

Research Research Networking and interconnect protocols are now part of the AI infrastructure thesis, not a separate plumbing layer.
Technology

From RoCE to MRC

AI cluster transport is being rethought around endpoint intelligence, chip design, and operational control.
