An easy one would be: have each GPU raytrace a (say) 320x240 scene, each offset by fractions-of-a-pixel[0] or multiples-of-a-screen from each other, then have a final GPU stitch them together into a full-res video.
0: If you this with 60x1080 resolution, you might be able to replace the final GPU with a dumb hardware multiplexer, though that would make compositing painful at best.
- jamesfmilne 8y agoThat’s literally what we used to do for our cluster colour grading systems for films. We had hardware that the would merge DVI from up to 8 GPUs, in separate nodes, and produce a single image.
