Hi Dionysios, the problem was simply due to some trivial bugs of my giraph implementation. Now I'm able to produce the same output both from graphlab and my giraph implementation of 4-profiles calculus. For instance I used http://snap.stanford.edu/data/p2p-Gnutella08.html as input graph. Regarding

Hi Francesco, Here are few thoughts on reasons this may happen: - I haven't written any graphlab application myself, but the synchronous vs. asynchronous model can generally be a reason for differences. It is possible that such differences do not manifest on smaller graphs. What's the size of the

Hi, I implemented in giraph the calculus of 4 profiles ( https://people.csail.mit.edu/jshun/papers/ESBD16.pdf) already implemented here https://github.com/eelenberg/4-profiles with graphlab. I'm able to run both graphlab e giraph programs. I know well differences between graphlab and giraph but I h
