I did mean the details on the graph modification. Up so far I have
not understood what is the problem in modifying the graphs in the engine.
It sounded like you solved the problem using lock-free par prog
techniques. By reading the solution I could catch up the problem. ;-)
Want explane what kind of modifications you mean? Why they take
so much time?
