Efficient multicast algorithms in all-port wormhole-routed hypercubes
V. Halwan, F. Özgüner · 2002
This paper presents several recursive heuristic methods for multicasting in all-port dimension-ordered wormhole-routed hypercubes. The methods described are stepwise contention-free and are primarily designed to reduce the number of communication steps. Experiments show that the number of steps can be significantly reduced compared to depth contention-free solutions previously described. These methods are also shown to be source-controlled depth contention-free and can be considered a generalization of the broadcast method described by C.T. Ho and M. Kao (1995) which is the most efficient method known.
