parallel_transform_reduce()

template<class ExecSpace , class Support , class ChunkDst , class BinaryReductionOp , class UnaryTransformOp >
requires (ddc::is_borrowed_chunk_v<ChunkDst>)

void ddc::experimental::parallel_transform_reduce ( std::string const &  label, ExecSpace const &  execution_space, Support const &  domain, ChunkDst &&  out, BinaryReductionOp const &  reduce, UnaryTransformOp const &  transform  )

noexcept

Performs a parallel transform-reduce over an nD domain using a Kokkos execution space.

For each element of out, a reduction is performed over the dimensions of domain that are not present in out.domain(). The reduction combines the values obtained by applying transform to each element of the corresponding subdomain.

Parameters

[in]	label	name used to identify the Kokkos kernel.
[in]	execution_space	Kokkos execution space on which the reductions are executed.
[in]	domain	full domain over which the transform-reduce is defined.
[out]	out	chunk receiving the reduction result for each point of out.domain(). Its domain must be a subdomain of domain.
[in]	reduce	binary reduction operator used to combine transformed values. It must be compatible with the value type stored in out.
[in]	transform	unary function applied to each element of the reduction subdomain. Its return type must be accepted by reduce.
