CUDA FOR LINUX
1) Download Toolkit for your system
2) Download Drivers for your system
******************************************************************************

Installing OpenCL on Ubuntu Linux with NVIDIA graphics card

Download the CUDA toolkit for Ubuntu from NVIDIAs CUDA site. Open a terminal an run the installation file with the command:

sudo sh cudatoolkit_3.1_linux_64_ubuntu9.10.run

Download the Developer Drivers for Linux at the same website and install it by first stopping X, running the file and start X again. Do stop X use:

sudo /etc/init.d/gdm stop

(lightdm)

Then get a terminal up by pressing CTRL+ALT+F5, login and navigate to where you downloaded the devdriver then type:

sudo sh devdriver_3.1_linux_64_256.40.run

After the driver has been installed start x again by typing

startx

Before compiling an OpenCL application you need to add the path to the lib folder of CUDA to LD_LIBRARY_PATH like so:

export LD_LIBRARY_PATH=/usr/local/cuda/lib64
