Yes, you know which vertex you are and in which step you are, so if you
implement it correctly you can run during the first superstep some
computations on vertex(2) and in the second superstep on vertex(5)

You could simply ignore your compute function in the first superstep on all
vertices except vertex2 and in the end send out messages to those vertices
which should continue with the computation. You could also run your compute
function on only one vertex in each superstep, but then I'm not quite sure
why you would want to use giraph.

cheers
Peter
