RHiNET‐2/SW: High‐speed network switch implemented with parallel optical interconnection for parallel computing system

Abstract

SUMMARYWe developed the RHiNET-2/SW high-speed network switch for a high-throughput parallel computing system consisting of optically interconnected distributed personal computers (PCs). RHiNET-2/SW enables highthroughput network switching (64 Gbit/s) by means of a switching LSI and eight pairs of synchronized parallel optical interconnection modules. To confirm the reliability of RHiNET-2/SW, we measured its bit error rate (BER), which was less than 10 -11 (estimated value: 10 -20 ). Five RHiNET-2/SWs and sixteen PC nodes can perform parallel computing. This result demonstrates the feasibility of optical interconnection in a high-speed, flexible network in a parallel computing system.
