OPTICALLY INTERCONNECTED MULTICOMPUTERS USING INVERTED-GRAPH TOPOLOGIES

To successfully exploit the benefits of optical technology in a tightl y coupled multicomputer, the architectural design must reflect both th e advantages and limitations of optics, This article describes a class of such architectures, based upon inverted-graph topologies, We consi der the physical construction of these systems, demonstrating the rele vant technological components necessary to manufacture a working syste m. We then consider sample inverted-hypercube and inverted-mesh topolo gies, illustrating their properties, including processor labeling, top ological embeddings, and message-routing algorithms.
