  • Massively parallel distributed-memory architectures are receiving increasing attention to meet the increasing demand on processing power. Many topologies have been proposed for interconnecting the processors of distributed computing systems. The hypercube topology has drawn considerable attention due to many of its attractive properties. The appealing properties of the hypercube topology such as vertex and edge symmetry, recursive structure, logarithmic diameter, maximally fault-tolerance, simple routing and broadcasting, and the ability to simulate other interconnection networks with minimum overhead have made it an excellent candidate for many parallel processing applications. Many variations of the hypercube topology have been reported in the literature, mainly to add to the computational power of the hypercube. One of the attractive versions of the hypercube that was introduced to enhance the performance is the twisted hypercube. A twisted hypercube has the same structural complexities of the hypercube. It preserves the attractive properties of the hypercube and improves on the communication time by reducing the diameter by a factor of two. This paper presents the basic communication and some of the basic operations usually needed in parallel computing on the twisted hypercube interconnection network. [ABSTRACT FROM AUTHOR]
