This page contains an online hands-on introductory CUDA tutorial. It consists of a movie, and a document containing instructions on how to perform the practical exercises (including how to get the template files). For the hands-on part, you will need access to CUDA-enabled NVIDIA GPU. There are 2 exercises. The first, Getting Started with CUDA, can be attempted after the first 41 minutes of the movie. The remaining part of the movie discusses CUDA optimisation techniques, after which the second exercise, Optimising an Application, can be attempted.
