As communication distances and bit rates increase, opto-electronic interconnects are becoming de-facto stan - dard for designing high-bandwidth low-latency intercon- nection networks for high performance computing (HPC) systems. While bandwidth scaling with efficient mul- tiplexing techniques (wavelengths, time and space) are available, static assignment of wavelengths can be detri- mental to network performance for adversial traffic pat- terns. Dynamic bandwidth reconfiguration based on ac- tual traffic pattern can lead to improved network perfor- mance by utilizing idle resources. While dynamic band- width re-allocation (DBR) techniques can alleviate inter- connection bottlenecks, power consumption also increases considerably. In this paper, we propose a dynamically reconfigurable architecture called E-RAPID (Extended- Reconfigurable, All-Photonic Interconnect for Distrib- uted and parallel systems) that not only dynamically re- allocates bandwidth, but also reduces the power consump- tion for all traffic patterns. Our proposed LS (Lock-Step) reconfiguration technique combines Dynamic Power Man- agement (DPM) with DBR techniques, achieving a reduc- tion in power consumption of 25% - 50% while degrading the throughput by less than 5%. |
