Overview
With the end of Dennard Scaling and a slowdown in Moore’s Law, the Cloud-Native Server Architecture project focuses on designing CPU architectures that maximise performance per unit area (perf/mm²) and performance per watt (perf/W) for modern cloud workloads. This work builds on the project’s broader goal of addressing slowing logic-density improvements through cross-layer integration and specialisation, from algorithms to silicon, while minimising data movement through tighter coupling of computation with emerging storage and networking technologies.
