I have downloaded CUDA-SDK-samples, CUDA-Included-Driver,CUDA-toolkit from NVIDIA website. Also, the version of gcc is 4.8, and nvcc is already installed in ububtu.
Detailed Information of Ubunut is like this:
Linux cuda 3.13.0-24-generic #46-Ubuntu SMP
Thu Apr 10 19:11:08 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
When I try to check the NVIDIA driver using ‘nvidia-smi’ command, error msg appears:
Unable to determine the device handle for GPU 0000:07:00.0: Unknown Error
So, I used ‘deviceQueryDrv’ and result of the query is:
./deviceQueryDrv Starting...
CUDA Device Query (Driver API) statically linked version
cuInit(0) returned 101
-> CUDA_ERROR_INVALID_DEVICE (device specified is not a valid CUDA device)
Result = FAIL
At first, I thought this msg means that CUDA is not supported on this GPU. However, it is in the list of NVIDIA-CUDA-SUPPORTED-PRODUCT. The informaition of this GPU is like this:
07:00.0 VGA compatible controller: NVIDIA Corporation Device 1001 (rev a1) (prog-if 00 [VGA controller])

Kernel driver in use: nvidia
NVIDIA Corporation Device 1001 is called ‘Titan Z’ and the driver installed in this computer is 331.xx.
I cannot figure out which part is wrong.
