Hi, there.
After installing new CUDA driver 3.1.17, all stuff including sample code and my code doesn’t work.
Every code said that “cudaGetDeviceCount FAILED CUDA Driver and Runtime version may be mismatched.” or unspecified driver error.
Is anybody who experienced the same problem?
Thanks.
Yes and I tried updating the toolkit from the NVIDIA MacOS download page
http://developer.nvidia.com/object/cuda_3_…t_rc.html#MacOS
it still didn’t work (they are pushing 3.2…I tried also updating driver using that link as well)…
Then I went back to the archive version for the toolkit and driver again it still didn’t work…
I also tried rebooting in 32-bit and the 64-bit …nothing fixes it…I am going to try all permutations and see
I thought perhaps the graphics card was broken till I tried the OpenCL version of deviceQuery and it worked.
so it must be software is screwed up

Ok I finally got it to work looking on the cuda on linux boards there was some similar issues which could be
fixed by using sudo command…(i.e. some how the permissions to run the SDK tests got screwed up)…I was
able to run the device query and bandwidth test without errors by using the sudo command first. I am now running
Cuda driver 3.2.7 (the one on the developer download site and toolkit 3.2) I am not sure why my auto cuda driver updater
wants to update me to 3.1.17 while the official developer site has 3.2.7 driver and 3.2 toolkits???
