How will multiple GPUs be supported?

Radiance-

Just curious how will multi GPU cards in a single system work? I understand that each GPU must have a copy of the data to be rendered...but will it be possible to split portions of a single image/render between multiple GPU cards? Or will it support a single render job per GPU? Or is it some other method.

I'd like to use a 9600GT as the display card and (2) GTX 280s for rendering only.

Thanks,

Charlie

Hi,

Yeah, you should be able to do that.
the multi-gpu setup will work transparently,
eg you're display denoises 2x as fast.

Thank you! Will the cards need to be in SLI (the two 280s) or not?

Thanks,

no, octane does'nt use SLI...

A related question: When rendering an animation will there be an option to tell Octane to render a single frame per gpu? So if I have 3 boards 3 frames would render in parallel. I can even turn off my monitor while Octane is rendering (to disk?).

yes, we'll provide documentation to do so once these functionalities are completed.

Just to be clear, 2 nVidia 295s will be 4x faster on a single image? Or can be used on 4 different images?

Hi,
this is my first post even if I'm around for a few days.
I just read about NVIDIA's Tesla 2070, a supercomputer disguised as a graphics card.
Is it in your project to make use of this power ?

Thanks for responding
