I am trying to run an application using GPU. I have setup all settings and drivers. My OS is Ubuntu14.04 LTS.
I checked whether I have CUDA capable device like
lspci | grep -i nvidia
05:00.0 VGA compatible controller: NVIDIA Corporation GK107GL [Quadro K2000] (rev a1)
05:00.1 Audio device: NVIDIA Corporation GK107 HDMI Audio Controller (rev a1)
My nvcc -V check gave me
li@li-HP-Z420-Workstation:/dev$ nvcc -V
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2015 NVIDIA Corporation
Built on Tue_Aug_11_14:27:32_CDT_2015
Cuda compilation tools, release 7.5, V7.5.17
Then my version check
li@li-HP-Z420-Workstation:/dev$ cat /proc/driver/nvidia/version
NVRM version: NVIDIA UNIX x86_64 Kernel Module 352.41 Fri Aug 21 23:09:52 PDT 2015
GCC version: gcc version 4.8.4 (Ubuntu 4.8.4-2ubuntu1~14.04)
I checked in the dev/ folder, I have nvidia0.
crwxrwxrwx 1 root root 195, 0 Sep 10 16:51 nvidia0
crw-rw-rw- 1 root root 195, 255 Sep 10 16:51 nvidiactl
When I run ./deviceQuery
…/NVIDIA_CUDA-7.5_Samples/bin/x86_64/linux/release/deviceQuery Starting…
CUDA Device Query (Runtime API) version (CUDART static linking)
cudaGetDeviceCount returned 38
→ no CUDA-capable device is detected
Result = FAIL
Then I run
ln@ln-HP-Z420-Workstation:/$ nvidia-smi -a
