Here, we explore CUDA, a programming language/environment from Nvidia. We'll experiment with CUDA 5.5 on OSX and Ubuntu. After installing the necessary CUDA toolkit from Nvidia's website, we can do (OSX 10.7.5, with a GeForce 9400 card with 256MB mem):
Updated for 2018: Ubuntu 18.04, Nvidia Quadro P1000, CUDA 9.2
