Abstract
In this paper, we describe an evolutionary technique aimed at scheduling collective communications on interconnection networks of parallel computers. To avoid contention for links and associated delays, collective communications proceed in synchronized steps. Minimum number of steps is sought for the given network topology, wormhole (pipelined) switching, minimum routing and given sets of sender and/or receiver nodes. Used technique is able not only re-invent optimum schedules for known symmetric topologies like hyper-cubes, but it can find schedules even for any asymmetric or irregular topologies in case of general many-to-many collective communications
