Detailed Description

The communication tree builders for tree-based algorithms of bcast/reduce/scatter/gather must implement a function:

void build(int size, int root, int rank, int count,
    Graph& g, Vertex& r, Vertex& u, Vertex& v);

Parameters:

	size	communicator size
	root	root process
	rank	current process
	count	message size in bytes (count * extent)
	g	graph
	r	root vertex (introduced to avoid search)
	u	parent of v (introduced to avoid search)
	v	vertex for the current process (introduced to avoid search)
