I've just got a new MBP with a GeForce 650M. I've downloaded an installed the latest CUDA driver (5.0). After doing so, I was getting out of memory errors for the GPU when trying to run one of the GPU demos. I restarted MATLAB. Then I got a general "unknown" error when trying to execute any gpu commands. So I restarted the computer. Now I'm getting a msg that says no supported CUDA devices. When I execute "gpuDeviceCount" I get 0. I also tried the following:
>> parallel.internal.gpu.CUDADriverVersion Error using iMacDriverVersion (line 96) Could not read version information from "/System/Library/Extensions/NVDAResman.kext/Contents/Info.plist".
Error in /Applications/MATLAB_R2011b.app/toolbox/distcomp/gpu/+parallel/+internal/+gpu/CUDADriverVersion.p>CUDADriverVersion (line 13)
So basically nothing works now, and it cannot even find the device. I'm not sure how to proceed. Any ideas suggestions? I'm running R2011_b.
