Abstract	A new scalable interconnection topology suitable for massively parallel systems called the Spanning Bus Connected Hypercube (SBCH) is proposed. The SBCH uses the hypercube topology as a basic building block and connects such building blocks using multi-dimensional spanning buses. In doing so, the SBCH combines positive features of both the hypercube (small diameter, high connectivity, symmetry, simple routing, and fault tolerance) and the spanning bus hypercube (SBH) (constant node degree, scalability, and ease of physical implementation), while at the same time circumventing their disadvantages. The SBCH topology permits the e cient support of many communication patterns found in di erent classes of computation such as busbased, mesh-based, tree-based problems as well as hypercube-based problems. A very attractive feature of the SBCH network is its ability to support a large number of processors while maintaining a constant degree and a constant diameter. Other positive features include symmetry, incremental scalability, and fault-tolerance. It is shown that the SBCH network provides better mean internode distance, average tra c density, packet delay, and cost than many similar networks, including the binary hypercube, the SBH, the Optical Multi-Mesh Hypercube etc. An optical implementation methodology is proposed for SBCH. The implementation methodology combines both the advantages of free space optics with those of wavelength division multiplexing techniques. A detailed analysis of the feasibility of the proposed network is also presented.
