CUDA for Tesla card (C2050)

Hi All,

I have following 2 cards installed on my workstation.

$ lspci | grep -i nvidia
03:00.0 VGA compatible controller: nVidia Corporation G98 [Quadro NVS 295] (rev a1)
04:00.0 VGA compatible controller: nVidia Corporation GF100 [Tesla C2050] (rev a3)
04:00.1 Audio device: nVidia Corporation GF100 High Definition Audio Controller (rev a1)

I have installed the cudatoolkit and NVIDIA_GPU_Computing_SDK.

However, when i try to test the installation by running devicequery. I get the following error.

~/NVIDIA_GPU_Computing_SDK/C/bin/linux/release$ ./deviceQuery
./deviceQuery Starting…

CUDA Device Query (Runtime API) version (CUDART static linking)

NVIDIA: could not open the device file /dev/nvidia1 (No such file or directory).
cudaGetDeviceCount FAILED CUDA Driver and Runtime version may be mismatched.

FAILED

Press to Quit…

Could you please help me in this matter ?

thanks.

The CUDA device files are not created unless you start X or you run the script on page 6 of the Getting Started Guide:

Note that you need to recreate the files in /dev every boot, so you probably want the script in your startup routine.
