Design and Performance of Generalized Interconnection Networks

This paper introduces a general class of self-routing interconnection networks for tightly coupled multiprocessor systems. The proposed network, named a "generalized shuffle network (GSN)," is based on a new interconnection pattern called a generalized shuffle and is capable of connecting any number of processors M to any number of memory modules N. The technique results in a variety of interconnection networks depending on how M nd N are factored. The network covers a broad spectrum of interconnections, starting from shared bus to crossbar switches and also includes various multistage interconnection networks (MIN's).
