Hypercube Vs Cube-Connected Cycles: A Topological Evaluation
Srikanth Kambhatla · 2005
Hypercubes and cube-connected cycles differ in the number of links per node which has fundamental implications on several issues including performance and ease of implementation. In this paper, we evaluate these networks with respect to a number of parameters including several topological characterizations, fault-tolerance, various broadcast and point-to-point communication primitives. In the process we also derive several lower bound figures and describe algorithms for communication in cube-connected cycles. We conclude that while having lower number of links per node in a CCC might not degrade performance drastically (especially for lower dimensions) as compared to a hypercube of a similar size, this feature has several consequences which substantially aid its (VLSI and non-VLSI) implementation. Keywords: topological evaluation, Cube-connected cycles, communication primitives, faulttolerance, implementation issues. 1. Objective The hypercube topology [1] has been a popular interco...
