The current way how groom reports status back to master is done by periodically rpc using groom server's main thread. Probably this action can be executed by another thread.
If I remember correctly, client would only receive the final superstep report if child process reports status in done() method. But I think profiling would better tell us what parts is the bottleneck. -----Original message----- From:Tommaso Teofili <[email protected]> To:[email protected] Date:Thu, 3 Nov 2011 12:18:41 +0100 Subject:Re: Experiences with large hama cluster. 2011/11/3 Thomas Jungblut <[email protected]> > It is difficult to say what the real bottleneck is. > > >What If each child processes reports directly using done() method? > > You want to report directly from a task to the master? > We need the status update to detect failure and stuff.
