Edward J. Yoon commented on HAMA-704:
-------------------------------------
I'm reading old code closely. To update the counts of updated vertices
globally, the total superstep was 2 times of iteration. With sorted message
queue, we can reduce synchronization times by half.
I think, my patch will improve both the performance and memory usage.
