Flat-Topology High-Throughput Compute Node With AWGR-Based Optical-Interconnects

  title={Flat-Topology High-Throughput Compute Node With AWGR-Based Optical-Interconnects},
  author={Paolo Grani and Roberto Proietti and Stanley T. S. Cheung and Sung-Joo Yoo},
  journal={Journal of Lightwave Technology},
This study presents simulation studies on the execution time and energy consumption of optical multi-socket boards with on-chip, all-to-all, and contention-less arrayed waveguide grating routers-based interconnection. This study considers throughput and energy-efficiency optimizations based on dynamic voltage and frequency scaling under realistic, shared memory, and cache-coherent PARSEC benchmarking traffic. The benchmark results show how a low-latency, optical inter-socket interconnection can… CONTINUE READING
