Detailed Description

template<int arity, typename ZipOp, typename RedOp>
struct stapl::skeletons::skeletons_impl::zip_reduce< arity, ZipOp, RedOp >

This class abstracts the semantics of a zip_reduce skeleton by exposing only the necessary information in its representation.

A zip_reduce skeleton is a skeleton that first combines the given inputs pairwise and then applies a reduction on the produced results in order to produce one result.

The most used specialization of a zip_reduce is a map_reduce in which only one input is passed in to the skeleton.

This abstraction not only makes the reconstruction of a a zip_reduce skeleton easier, but also reduces the symbol size for a zip_reduce skeleton, hence, reducing the total compilation time.

Template Parameters

arity	the arity of the zip skeleton.
ZipOp	the underlying operation to combine the input element.
RedOp	the underlying operation to reduce the produced result by the zip skeleton.
