Compute function calls

[Kostas Xirog <k0...@gmail.com>]

 How does Hama (graph) call the compute function? I've managed to load my
graph into the system the way I want it, all the nodes and the edges and
everything, but I can't figure out how hama calls the compute function...

According to the  Pregel paper, the compute function is called , in the
beginning of the program run, (in superstep 0) and every time that
node receives a message from another node...

Is there something I can read where it will tell me how Hama (graph) works
in the background?

Thanks in Advance

Browse GraphJobRunner[1] and ctrl + f '.compute'.

We are the same. 'The compute function is called, in the beginning of
the program run, (in superstep 0) and every time that vertex receives
a message from another vertex'.

Sorry, not yet. Maybe later I'll write up about the internals. :-)
