Detailed Description
template<class SolutionState_t, class NeighborStrategy_t>
class MasterNode< SolutionState_t, NeighborStrategy_t >
Implements a node in the network of all pilots, exposing store and collect operations on a specific set of neighbors.
Using the neighbor strategy a set of neighbors we collect solution state from (and they collect from us) is defined. Using this set of neighbors the solution states propagate throughout the network. The store and collect operations are implemented using one sided MPI communication methods (simulating shared memory). A revision number is used to prevent receiving previously collected solution states from neighbors.
