OTOY Forums

I am using a Macbook Pro with a nVidia GeForce 9400m, which is on the list of CUDA capable GPU. In January 2011, I installed and successfully ran Octane, but removed the program because I didnt have time to play with it. Today, I installed the latest version from scratch 1. latest CUDA driver 2. CUDA toolkit 3. octane. When I open Octane now, the splash screen loads but is followed by the "no CUDA capable devices found, exiting" message. I am stumped.

any ideas?

On a Mac you have to install 3 components to make a CUDA application run and all 3 of them must work together properly:
- the NVIDIA graphics driver
- the NVIDIA CUDA driver
- the NVIDIA CUDA toolkit

The graphics driver comes usually with your OS updates and should not be touched. If you are using the latest Mac 10.6, it should be ol.

The current demo version (beta 2.46b) requires CUDA toolkit 3.2 (http://developer.nvidia.com/cuda-toolkit-32-downloads) and the CUDA driver 3.2.17 (http://www.nvidia.com/object/macosx-cud ... river.html). Please install these and try again. Maybe also have a look at the video tutorials (http://www.refractivesoftware.com/demotutorial_mac.html).

I also have a similiar problem.

I have:
- MBP
- OSX 10.6.8
- NV 9600M
- CUDA driver v4 + toolkit v4

Are you saying the demo specifically requires CUDA 3.2 and doesn't
support CUDA 4? Unfortunately I can't downgrade my CUDA version
as I have other apps that depend on CUDA 4.

I'm really keen to try and buy, so I'd appreciate if you can find time to
recompile the demo to work with CUDA 4. Thanks.

Hi,

We will be releasing the new v1.0 beta 2.52 as a DEMO version in a few days which is CUDA 4.0 dependant.
