@jerrypeng @HeartSaVioR Thanks for the review. Just one question, do we
use two Histograms one for the number of the topology and the other one for the
time the scheduling takes? I didn't find any way to combine these two together
in one Histogram. But I think we might not want to deal with these two
separately.---
