Routing permutations in partitioned optical passive stars networks [PDF]

open access: yesProceedings 16th International Parallel and Distributed Processing Symposium, 2002
It is shown that a POPS network with g groups and d processors per group can efficiently route any permutation among the n=dg processors. The number of slots used is optimal in the worst case, and is at most the double of the optimum for all permutations p such that p(i)<>i for all i.
