Why UALink Configuration Needs Real Workload Simulation for LLM Data Centers
June 8, 2026
UALink configuration for AI data centers cannot be selected from bandwidth numbers alone. For LLM workloads, teams must understand how data moves across CPUs, GPUs, XPUs, memory, and interconnects. This article explains how VisualSim Architect uses GPT-style task graphs and digital twin simulation to evaluate latency, power, energy, congestion, and workload performance before hardware is finalized.
