CUDA/GPU install

assuming you’re installing GPU + CUDA from scratch, here’s the steps
for a linux i686:

1. Find and download appropriate driver from Nvidia. With the old GPU card still in place, switch to terminal ‘ctrl-alt-F1’ and as root stop the X-server by issuing ‘init 3’. Then install via ‘sh NV*run’, answering yes to all the prompts. Issue ‘init 5’ and shut down… when done, replace video card

2. Reboot and install the CUDA toolkit, don’t forget to ‘chmod +x cud*run’ before issuing ‘sh cud*run’. After answering yes to all the prompts & installing, add to .bash_profile:

PATH=$PATH:/usr/local/cuda/bin
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib

export PATH
export LD_LIBRARY_PATH

3. Install the CUDA SDK, you should be good to go, but may also need to disable SELinux (eg., temporarily: ‘echo 0 > /selinux/enforce’)
