Detailed Description

template<class Strategy_t>
class CommSplitter< Strategy_t >

Role assignment according to strategy (that might use hardware network information).

The CommSplitter splits the passed (usually MPI_COMM_WORLD) communicator into several comm groups using the colors provided by the splitting strategy. After construction each processor has an assigned role (optimizer, worker or pilot) and a set of communicators to send and receive tasks. The expected colors have the following meaning:

color[0] is shared by all my co-workers
color[1] is shared by the optimizer leader and the pilot
color[2] is shared by the worker leader and the pilot
color[3] is shared by all processors with the same role (used for broadcasts)
