Hierarchical optical ring interconnection (HORN): scalable interconnection network for multiprocessors and multicomputers.
نویسندگان
چکیده
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 interconnection topology that uses wavelength-division multiple access to provide better utilization of the terahertz bandwidth offered by optics. 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, its architectural properties are analyzed, and an optical design methodology for it is described. Furthermore, a brief feasibility study of the HORN is conducted. The study shows that the topology is highly amenable to optical implementation with commercially available optical elements.

A prototype of a novel topology for scalable optical interconnection networks called Optical Multi-Mesh Hypercube, OMMH, is experimentally demonstrated up to 150Mb=s data rate (2 7 1 NRZ pseudo random data pattern) at a bit error rate of 10 13 per link using commercially available devices. OMMH is a scalable network architecture which combines positive features of the hypercube (small diameter,...
متن کاملChannel Allocation , Power Budget And Bit Error Rate
Recent advances in computer processing speeds have resulted in a parallel processing environment in which the interconnection networks themselves are the limiting factor in terms of performance. One approach to circumvent this limitation is to arrange processing nodes in a hierarchical manner. In a hierarchical network, nodes are arranged in clusters of one or more nodes and these clusters are ...
