Right now there is no good way to do that, sorry.

If you're recalculating large parts of your scene for every frame you
need to do that on the slaves, to utilize all the processors. OpenSG
doesn't directly help you with that at this point.
You can use the OpenSG infrastructure for it, but you would have to
write your own NodeCore that does the calculations when it's asked to
rerender itself, and you would need to be able to calculate the counding
box of the slaves' contributions on the master, so that the SortLast
compositors can schedule the data transfer correctly. You would also
have to add some code to the SortLast cluster logic to recognize your
new Nodes.
So it's not that trivial right now. It's something that I'm very
interested in, but have not been able to spend time on. Can you give us
a little intro to your problem?
Yours
Dirk
