There is support that Claudio added for exporting aggregator values
(https://issues.apache.org/jira/browse/GIRAPH-10). You could probably
also do your final computation there if that is what you want (if you
want to do end of application manipulation). WorkerContext would be a
good way to do aggregator manipulation in between supersteps (or at the
end), as you suggested as well. Is the manipulation you want to do in
between supersteps or just at the end of the application?

I'm working on an algorithm that computes a global value of the graph

this value can be computed. What would be the correct place to implement
I thought about WorkerContext first, but it seems that this is run on
each worker, which doesn't really fit my problem. Another question would
be how to persist that global value after the algorithm is done.
