Performance benefits of optical circuit switches for large-scale dragonfly networks

We propose Optical Circuit Switching for dynamically creating reconfigurable partitions in large-scale systems with Dragonfly networks. Up to 2x execution-time improvement is demonstrated for global traffic patterns in a >13,000-node system using a production-grade network simulator.
