template<typename Value, typename BinaryOp, typename OutKey>
class ttg::BinaryTreeReduce< Value, BinaryOp, OutKey >
generic binary reduction of a set of key-value pairs.
This reduces a set of Value objects keyed by an integer in the [0,max_key) interval using BinaryOp op . The reduction order is determined by breadth-first traversal of a binary spanning tree of the complete graph of the [0,max_key) set (see BinarySpanningTree) rooted at a particular key; at each node Node the reduction is performed as op(op(LeftSubTree,Node),RightSubTree) . The primary use is for reducing over a World, hence by default the keymap is identity (keymap(key) = key) and max_key=world.size() . The result is associated with output key dest_key .
- Note
- this is equivalent to MPI_Reduce; unlike std::reduce this lacks the initializer value.
