UALink Under The Hood: Why Full-Stack Verification Wins


It is tempting to picture UALink as a clean line between two accelerators: requests enter one side, responses emerge from the other. The abstraction is useful — but it conceals almost everything that makes the protocol interesting, and almost everything that makes it difficult to verify. Verifying UALink means following a transaction the way the silicon does: down through four layers, out ... » read more

System-Level Design For 1.6 Tbps Interoperability In AI Data Centers


By Madhumita Sanyal and Diwakar Kumaraswamy The rapid escalation of AI/ML workloads—driven by increasingly large language models—is reshaping high-performance computing and AI data center architectures. Real-time inference and large-scale training are pushing the limits of compute and interconnect performance. With model sizes and parameter counts doubling every 4–6 months, infrastruct... » read more

UALink: Powering The Future Of AI Compute


On April 25, the UALink Consortium officially released the UALink 200G 1.0 Specification, marking an important milestone with support from key hyperscalar market players. It enables a low-latency, high-bandwidth fabric that supports hundreds of accelerators in a pod and facilitates simple load-and-store semantics. Motivation behind UALink The rapid evolution of Artificial Intelligence (AI) an... » read more
