const Teuchos::RCP< const Teuchos::Comm< int > > comm_ ) const
pure virtual

Function is called whenever nprocs > no_task. Function returns only the subset of processors that are closest to each other.

Parameters
proc_to_task_xadjholds the pointer to the task array
proc_to_task_adjholds the indices of tasks wrt to proc_to_task_xadj array.
task_to_procholds the processors mapped to tasks.

Implemented in Zoltan2::CoordinateCommunicationModel< pcoord_t, tcoord_t, part_t, node_t >, and Zoltan2::CoordinateCommunicationModel< pcoord_t, tcoord_t, Zoltan2::InputTraits< User >::part_t, Zoltan2::InputTraits< User >::node_t >.
