template<size_t Dim>
class ripple::kernel::cpu::detail::Reducer

Forward declaration of a struct to perform a reduction in the given number of dimensions.

Struct to define a reducer for a domain with the given number of dimensions.

Template Parameters

• Dims: The number of dimensions for the reduction.

• Dim: The number of dimensions in the domain.

Public Static Functions

template<typename Iterator1, typename Iterator2, typename Pred, typename ...Args>
auto reduce(Iterator1 &&it, Iterator2 &&result, Pred &&pred, Args&&... args) noexcept -> void

Performs a reduction in the given dimension by performing a reduction on each of the (rows/planes) in the Dim - 1 dimension.

Parameters

• it: The iterator to reduce the data over.

• result: The iterator to reduce into.

• pred: The predicate to apply to each of the elements.

• args: Additional arguments for the predicate.

Template Parameters

• Iterator1: The type of the first iterator.

• Iterator2: The type of the second iterator.

• Pred: The type of the predicate.

• Args: The type of the predicate additional arguments.
