Efficient broadcast on hypercubes with wormhole and e-cube routings
Abstract
We consider the problem of broadcasting on an n-dimensional hypercube with worm-hole e-cube routing, intermediate reception capability, and one-port communication. We give an algorithm, optimal to within a multiplicative constant, that broadcasts in this model in Θ(n/log2(n + 1)) routing steps. We also give routing algorithms that achieve tight time bounds for n-cubes where n ≤ 6.
