> Using one-to-all message sending to send one message copy to multiple target vertices on the same worker.
> To enable this feature, use conf.enableOneToAllMsgSending(). 
> Pagerank benchmarking (Partitions: 640, Edges per vertex: 500, Vertices: 200000000, Workers: 40)
> shows that the time per superstep is reduced by 40%.
