So, the 17" Macbook Pro (http://www.apple.com/macbookpro/specs.html) has two NVIDIA chips in it, the 9400M with 256MB of memory and the 9600M GT with 512MB of memory - in normal operation it just has the 9400M on, and leaves the 9600M in reserve for the heavy lifting.
I installed the CUDA SDK and Tools and deviceQuery is only seeing the 9400M and its 256MB of memory. Is there some trick to enabling the 9600M? Is it possible to task both GPUs with CUDA?
Thanks for any guidance.
