用于机群系统的高速光互连网络接口卡设计

Design of a High speed Optical Interconnection Network Interface Card for Computer Cluster

本文在已设计完成的用于计算机点到虚拟并行互连的光互连链路基础上 ,用现场可编程门阵列(FPGA)器件实现了数据的寻址和转发 ,设计完成了具有硬件路由功能的光互连环网的网络接口卡。该网络接口卡的旁路数据转发延迟为 2 1 0 ns,目的结点的数据接收处理延迟为 35 0

WT5”BZ]:Based on the point to point virtual parallel optical interconnection data link that has been implemented,an optical interconnection network interface card with hardware routing function for ring network has been designed.Data routing and retransmitting are achieved on the card using a field programmable gate array (FPGA).Data pass through latency is 210 ns;data receiving latency at the destination node is about 350 ns.
