Incomplete Star: An Incrementally Scalable Network Based on the Star Graph

Introduces a new interconnection network for massively parallel systems called the incomplete star graph. The authors describe unique ways of interconnecting and labeling the nodes and routing point-to-point communications within this network. In addition, they provide an analysis of a special class of incomplete star graph called C/sup n/spl minus/1/ graph and obtain the diameter and average distance for this network. For the C/sup n/spl minus/1/ graph, an efficient broadcasting scheme is presented. Furthermore, it is proven that a C/sup n/spl minus/1/ with N nodes (i.e. N=m(n/spl minus/1)!) is Hamiltonian if m=4 or m=3k, and k/spl ne/2. >
