Functions
template<int dim>
void	DiFfRG::internal::unflatten_index (std::size_t flat, const device::array< size_t, dim > &grid_size, device::array< size_t, dim > &idx)
	Turn a row-major flat index into a multi-index.
template<int dim>
void	DiFfRG::internal::advance_index (const device::array< size_t, dim > &grid_size, device::array< size_t, dim > &idx)
	Advance a row-major multi-index by one (odometer increment).
template<int dim, typename NT , typename FUN >
NT	DiFfRG::internal::serial_sum (const device::array< size_t, dim > &grid_size, const FUN &functor, const std::size_t begin, const std::size_t end)
	Strictly row-major serial sum of functor over the flat index range [begin, end).
template<int dim, typename NT , typename FUN >
NT	DiFfRG::TBBReduction (const device::array< size_t, dim > &grid_size, const FUN &functor)
	Bitwise reproducible reduction of functor over a dim-dimensional index grid.

Variables

	Number of grid points below which a reduction is carried out serially.
constexpr std::size_t	DiFfRG::internal::reduction_grainsize = 256
	Leaf size of the deterministic reduction tree.
