一种用于并行计算系统的分级光环互连网络

介绍了大规模并行计算的一个新互连网络——分级光环互连，适用于多处理器与多计算机的可升级网络。分级光环互连由一个衡量无阻塞、容错的单跳可升级互连拓扑组成，并通过波分多址技术充分地利用了光纤的TeraHz带宽。此光网络融合了分级环的互连节点接口简单、节点度恒定、容错等各种吸引人的特征以及光通信的各种优点。提出了分级光环互连拓扑，分析了其结构特征并描述了光设计的方法，导出了一个简短可行的分级光环互连研究。

Hierarchical optical ring interconnection network for massively parallel computing

A new interconnection network for massively parallel computing is introduced. This network is called a hierarchal optical ring interconnection HORN. The HORN consists of a single-hop, scalable, constant-degree, strictly nonblocking, fault-tolerant in- terconnection topology that uses wavelengthdivision multiple access to provide better utilization of the terahertz bandwidth offered by op- tics. The proposed optical network integrates the attractive features of hierarchical ring interconnections, e.g., a simple node interface, a constant node degree, better support for the locality of reference, and fault tolerance, with the advantages of optics. The HORN topology is presented, and its architectural properties are analyzed, and an optical design methodology for it is described. Furthermore, a brief feasibility study of the HORN is conducted.
