Jan van der Lugt commented on GIRAPH-259:
-----------------------------------------
To me the difference between master-first or vertex-first is not very
important, but it seems more intuitive to run the master first (kind of
'leading the way', so to speak). I recall I have changed the code so BSPWorkers
also get aggregator values for superstep 0, so executing the master first
should not be a problem. The main problem there is now, is that the master
doesn't reset the value together with the workers, so the value is never
actually reset.
