Is there any quick command or script to check for the version of CUDA installed?
I found the manual of 4.0 under the installation directory but I'm not sure whether it is of the actual installed version or not.
How to get the CUDA version

As already pointed out, nvcc depends on gcc 4.4. It is possible to configure nvcc to use the correct version of gcc without passing any compiler parameters by adding softlinks to the bin directory created with the nvcc install.
The default cuda binary directory (the installation default) is /usr/local/cuda/bin, adding a softlink to the correct version of gcc from this directory is sufficient:
sudo ln -s /usr/bin/gcc-4.4 /usr/local/cuda/bin/gcc
To get real-time insight on used resources, do:
nvidia-smi -l 1
This will loop and call the view at every second.
If you do not want to keep past traces of the looped call in the console history, you can also do:
watch -n0.1 nvidia-smi
Where 0.1 is the time interval, in seconds.

As Jared mentions in a comment, from the command line:
(or
/usr/local/cuda/bin/nvcc --version) gives the CUDA compiler version (which matches the toolkit version).From application code, you can query the runtime API version with
or the driver API version with
As Daniel points out, deviceQuery is an SDK sample app that queries the above, along with device capabilities.
As others note, you can also check the contents of the
version.txtusing (e.g., on Mac or Linux)However, if there is another version of the CUDA toolkit installed other than the one symlinked from
/usr/local/cuda, this may report an inaccurate version if another version is earlier in yourPATHthan the above, so use with caution.
