Following our article on selecting CUDA and a supported linux distro, we will write about our install of CUDA 7.5 on Ubuntu 15.04 which are by the time of this ariting the most updated version of the SDK and OS. Once again, those post are more about taking note on our trial than a real “state of the art” tutorial about properly installing the CUDA development toolchain. To follow this step-by-step guide we are supposing you already have a running G2 AMI instance. Please refer to our part 1 for AMI selection.

Note: Windows user. Use PUTTY to SSH into your instance.
Past its public IP to the Host text-field then go to Category/Connection/SSH/Auth on the left panel to browse and load you private Key (use PUTTY Keygen utility to convert the downloaded .pem file into a .ppk file) Linux users will ssh into their instances using:
ssh -i .pem ubuntu@[Instance Public IP]

Before starting any CUDA related install you may want to update and upgrade the OS. Note that you can directly install CUDA first if you want.
