Hi Jyoti, Why do you want to do so in superstep 0? It should be done at the time of loading graph into the memory done by vif. You should have this extra value in the input file itself. Prepare your vertex input file in such a way that it has vertex id and that extra content. Then you can extract vertex id and value from that file.
