示例1: prepare_injective_join
void prepare_injective_join(LeftEmitKey left_emit_key,
RightEmitKey right_emit_key) {
typedef std::pair<size_t, vertex_id_type> key_vertex_pair;
// Basically, what we are trying to do is to figure out, for each vertex
// on one side of the graph, which vertices for the other graph
// (and on on which machines) emitted the same key.
//
// The target datastructure is:
// vtx_to_key[vtx]: The key for each vertex
// opposing_join_proc[vtx]: Machines which hold a vertex on the opposing
// graph which emitted the same key
// key_to_vtx[key] Mapping of keys to vertices.
// resize the left index
// resize the right index
reset_and_fill_injective_index(left_inj_index,
left_graph,
left_emit_key, "left graph");
reset_and_fill_injective_index(right_inj_index,
right_graph,
right_emit_key, "right graph");
rmi.barrier();
// now, we need cross join across all machines to figure out the
// opposing join proc
// we need to do this twice. Once for left, and once for right.
compute_injective_join();
