Armando Miraglia commented on GIRAPH-825:
-----------------------------------------

I have done several tests.
a) PseudoRandom input with millions of vertices and multiple threads for all input/computation/output
(20 at most)
b) Input wiht WattzStrogatz algorithm also with millions of vertices and multiple threads
c) I used also Sebastian's hyperball algorithm on twitter graph with 20 threads and 400 workers
d) FInally I tested it with LiveJournal social graph with textinput format and multiple threads.

These are the tests that I have attempted.

of semantic. The patch for this should fix it including currently open issues.
