Detailed Description
template<typename CELL, class STENCIL, bool BOUNDARY_WEST, bool BOUNDARY_EAST, bool BOUNDARY_TOP, bool BOUNDARY_BOTTOM, bool BOUNDARY_SOUTH, bool BOUNDARY_NORTH>
class LibGeoDecomp::LinePointerNeighborhood< CELL, STENCIL, BOUNDARY_WEST, BOUNDARY_EAST, BOUNDARY_TOP, BOUNDARY_BOTTOM, BOUNDARY_SOUTH, BOUNDARY_NORTH >
gives cells access to their neighboring cells in a given stencil shape.
It is meant as a low-overhead replacement for CoordMap. The flags are used in template specializations to cover those cases in which accesses to neighboring cells need to be rerouted. In essence, we go through the pain of having such many parameters to resolve runtime conditionals for range checking at compile time.
BOUNDARY_WEST: X == -1 -> use WEST pointers = X >= 0 -> use center pointers + X
BOUNDARY_EAST: X == 1 -> use EAST pointers X <= 0 -> use center pointers + X
BOUNDARY_TOP: Y == -1 -> use TOP pointer (don't set this on a torus, as its not needed!) Y >= 0 -> use center pointers + X
