What is the difference between Hops and clusters?

Got it! But hops running inside one process does not mean that multiple cores of the CPU couldn’t still be utilised no? Here is a CPU usage screenshot when I open a larger Kangaroo definition with RH8 (I guess running inside one Rhino process?)

Furthermore, would the ability to run hops components as separate processes go hand in hand with the ability to run multiple Rhino sessions as separate processes?

If yes, it would of course be an awesome thing to develop both these features in one go… in theory.
