TL;DR

A one-chip-like standpoint for understanding how datacenter infrastructures are evolving to support AI workloads is introduced, highlighting how one-chip-like datacenter extends chip-level semantics to rack scale by combining compute express link fabrics with hardware mechanisms, thereby stabilizing latency variability along traversal paths.

Co-Fabric: Breaking Host-Domain Boundaries for Unified xPU Interconnection

Large-model parameters have grown beyond the capacity of a single xPU, dispersing across multiple xPUs spanning distinct host domains, where xPU-to-xPU communication dominates overall system efficiency. Existing scale-up interconnect remains inadequate: network-based solutions built on Ethernet--such as RoCE (RDMA over...
