We consider the use of multiple-bus networks (MBNs) in a synchronous parallel processing environment. We propose a class of MBNs called bus-connected ringed trees (BRTs). A 1-dimensional BRT is shown to have an optimal processor fanout of 2 and to be capable of optimally simulating a complete binary

โฆ Synopsis
We present a novel interconnection topology, the Josephus Cube, which supports a simple routing strategy that is minimal, deadlock-and livelock-free. The topology can optimally embed linear arrays (LAs), rings, and complete binary trees of arbitrary size, as well as 2 p ร q meshes. It is also a supergraph of the n-cube and several of its variants and supports a degree of fault tolerance. Finally, the topology can systematically interconnect an arbitrary number of nodes and its scalability, diameter and communications performance compare favourably with those of the n-cube and its variants.

This paper proposes a bus-based cube-type network, called psi-cube, that alleviates the two problems, long wires and a limited number of I/O pins, against the on-chip systems through a small diameter and dynamic clusters, respectively. The 2 n -node psi-cube is organized on the sets of node-partitio
