compute_combine_trees()

int stapl::paragraph_impl::compute_combine_trees	(	float const &	n,
		std::vector< tree_info > &	trees
	)

Determines the set of balanced binary trees that are needed to represent a reduction of a specified number of view elements.

Parameters

n	The number of view elements to be processed. A real number is provided to avoid casting within the function before calling std::log2.
trees	Empty vector that will be populated with the statistics of the trees to be used when generating the task graph.
