=Installation af cuda=
Follow this tutorial: http://www.quantstart.com/articles/Installing-Nvidia-CUDA-on-Ubuntu-14-04-for-Linux-GPU-Computing

Note: Suggest that you navigate to sub-directories in the samples directory and "make" individual projects.  To "make" the whole samples directory (as the tutorial suggests) takes around an hour!

Note: .bash_profile is actually just called .profile
