CPU core to GPU relation

[doug-hines]

I'm looking into building a small to mid-sized renderfarm and I've been scouring the internet trying to find some reference as to how a CPU interacts with GPU cores.

Does a CPU core access the entire set of GPU cores at once, or can it access a subset of those cores?  Or am I thinking about this in an entirely wrong way?

Probably as it makes littele sense to think of the individual cores of a GPu as saparate unless you are doing your own rendering software. See the thing is you want to minimize the acces not maximize it, every time you do something directly between theese such as dumping instructions your slowing things down.
