The interconnection network is an important component in a parallel computer. A good interconnection network is expected to have least number of links, topological network cost and more reliable. The interconnection network must be able to scale up with a few building blocks and with minimum redesign. The hypercube is a network with high connectivity and simple routing but the node degree grows logarithmically with number of vertices making it difficult to build scalable architecture. Torus is a network with constant node degree and is highly scalable architecture but has larger network diameter. The advantages of hypercube and torus network can be superposed on to an embedded architecture called torus embedded hypercube scalable interconnection network.
