On a deadlock and performance analysis of ALBR and DAR algorithm on X-Torus topology by optimal utilization of Cross Links and minimal lookups

摘要

Interconnection networks play a major role in differentiating modern multiprocessor architectures. They can be categorized according to a number of criteria such as topology, routing strategy and switching technique. They are built up of switching elements; the topology is packaged such that it is cost effective along with its ability to achieve good performance. In this paper, we have studied an existing X-Torus topology (Gu et al. in ICCSA, LNCS, vol. 3984, pp. 149–157, 2006) which is an enhancement of a Torus network by adding Cross Links, and hence contributes to shorter diameter, shorter average distance and larger bisection bandwidth. Furthermore, we proposed the Adaptive Load Balanced Routing (ALBR) algorithm and Dual Adaptive Routing (DAR) algorithm.
