摘　　要：针对分布共享存储多处理器系统越来越严重的通信问题，本文提出了一种适用于分布共享存储多处理器系统的光互连网络结构，通过增加系统连通性和远程通信带宽，能有效降低系统的远程存储访问延迟，提升系统整体性能。采用密集波分复用技术的光互连网络能有效提升组装密度和通信带宽。同时，基于表面集成波导光电印制板和阵列光互连器件，构建了高速并行光互连原型样机，通过功能演示和相关测试，表明光互连技术可以应用于计算节点板级互连。This paper proposes an optical interconnection network architecture for large-scale distributed shared-memory multiprocessors（DSMs）. The architecture here reduces remote memory access latency by increasing connectivity and maximizing channel availability for remote communication. It also provides efficient and fast communication capabilities, using the wavelength-division-multiplexing technology. Then, based on polymer optical waveguide and array optical interconnect devices, we build a proto type for high-speed parallel optical interconnect. The test results show that it can be used in processing node for chip-to-chip interconnects of board level.
