This course will introduce students to the principles of writing scientific software for the latest graphics cards, taking advantage of the highly-parallel nature of the hardware to attain significant speed-ups as compared to traditional CPUs. The course will begin by covering the hardware structure of modern GPUs, and how this relates to the software model. Students will then be introduced to the C-like CUDA programming language which has been developed by NVIDIA, and be shown how to develop efficient algorithms using this language. Students will be introduced to general strategies for optimising code. The main examples used in the course will be related to the numerical solution of PDEs.
