Detailed Description

template<typename Op, typename Flows, typename Span, typename Tag, bool SetResult>
struct stapl::skeletons::skeletons_impl::broadcast< Op, Flows, Span, Tag, SetResult >

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

A broadcast skeleton is simply a broadcast tree, however, since a broadcast tree can only handle an input of power-of-two sizes, this skeleton composes a broadcast tree to a an expansion skeleton.

This abstraction not only makes the reconstruction of a broadcast skeleton easier, but also provides access to the underlying operation of a broadcast skeleton. Furthermore, it reduces the symbol size for a broadcast skeleton, hence, reducing the total compilation time.

Template Parameters

Op	the operation to be used while broadcasting.
Flows	the flow to be used for the broadcast_tree.
Span	the iteration space for elements on each level of the broadcast tree
tag	determines the type of the broadcast skeleton
