[jira] [Updated] (GIRAPH-701) Communication improvement using one-to-all message sending

     [ https://issues.apache.org/jira/browse/GIRAPH-701?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jesse updated GIRAPH-701:
-------------------------

    Description: 
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%.
