Hi,

I am implementing a machine learning algorithm on = top giraph. The algorithm converges when all the vertices call voteToHalt o= r some max number of supersteps have completed.=A0

I want to calc= ulate the RMSE error =A0after the algorithm has converged. But the problem = is either all the vertices have called vote to halt or (in the case where w= e reach max supersteps) only some of them are still active.

I need to reactivate or wake up all the vertices. Is there any way in = giraph that I could do this?

Thanks,

Ame= ya Vilankar
