Update: I should have mentioned that I'm also using a Quadro K600 for display. I've reinstalled both the GTX 320.18 and the Quadro/Tesla 320.00 drivers.

I removed the Tesla just to see if that could be causing a conflict. Still no CUDA GPUs available in octane. Please help!

All are showing up with no errors. I have a GTX 780, a Titan and a Tesla K20 in this system in order to run some benchmarks. I know this is an odd config and there may be a conflict with the GTX/Tesla drivers but I swear I've done this before without any issues.

Thanks

Hello,
I'm trying to run some benchmarks on my machine. I have 4 GPUs in the system. I have the latest octane build and the latest 320.18 NVidia driver. In octane it says no CUDA GPUs and nothing shows up in preferences under CUDA devices.

Any ideas?

Thanks
Joe

Hello all,
I recently finished testing octane on one of our 8 GPU servers and thought I'd share the results with the group. Saw some very fast render times and also noted how well the performance scaled up to 8 GPUs. I've been testing many GPU renderers lately and octane seems to be the only one ...

hello,
i switched over to beta 2.46b and everything seems to be working fine including proper performance scaling across all the gpus.

thanks

Hello all,
I'm trying to test my system with 8 GPUs. When I go to preferences>CUDA devices the option to add additional devices is greyed out. I have 1 active device and 7 inactive. Any thoughts? I'm wondering if it is a CUDA driver version issue perhaps.

Thanks

hello all,
am i able to use more than one GPU with the demo? the option to add aditional gpus is greyed out and i'm wondering if that is why. if not, please advise on how i can make the rest of my cards available.

thanks,
-joe

thanks for the info. i'll plan to benchmark with the demo suite and post back when i get some results. looking forward to it as well.

more info on these systems can be found here http://www.renderstream.com/VDAC.pdf

Hello All,

In about a week or so I'll be getting an 8 GPU system for internal testing and benchmarking here at RenderStream. I plan to benchmark most of the main GPU renderers including octane. I plan to see how the renderer performs in an 8 card configuration, as well as looking at how well it ...
