Detailed Description

template<class CollectiveCommunication, int d>
class Dune::Torus< CollectiveCommunication, d >::ProcListIterator

ProcListIterator provides access to a list of neighboring processes. There are always \( 3^d-1 \) entries in such a list. Two lists are maintained, one for sending and one for receiving. The lists are sorted in such a way that in sequence message delivery ensures that e.g. a message send to the left neighbor is received as a message from the right neighbor.
