HI,

I'm reading that paper and seeing few design pattens.

I agree with you that we should measure about the number of
iterations. And, as you said, there is still I/O overhead involved in
reading and writing materialized data every time, even if avoiding the
situation shuffle and sort of reduce phase.

IMO, BSP will communication only some vertices which can't be solved
locally, and I'm sure that the number of iterations will be less or
equal to (M/R based) Schimmy approach.

More I hope we can compare them using Hama BSP soon.
