Distributed Computing on Anonymous Hypercube Networks
Evangelos Kranakis, Danny Kriz̧anc · Journal of Algorithms · 1997
We consider the bit-complexity (i.e.a, total number of bits transmitted) of computing boolean functions on an anonymous canonically labeledn-dimensional hypercube network and give a characterization of the boolean functions computable on such a network as exactly those boolean functions which are invariant under all bit-complement automorphisms of the hyercube. We provide an efficient algorithm for computing all such functions with bit complexityO(N · log4 N). For the case of symmetric boolean functions we give an algorithm with bit complexityO(N · log2 N).
