CUDA definitely is not a new thing, so there's a lot of articles, tutorials etc. and I've read many of them, but I would not recommend some of them to others who begin with CUDA. And because I still remember which documents really were useful to me, I've prepared this short list of interesting links.
If you're a at least slighty geeky person and fancy of C, I definitely recommend you to check a thing called CUDA. Basically it's a way to use the GPU present at your nVidia graphics card for arbitrary parallel processing. And when I say parallel, I'm not thinking about stupid four cores but about 192 cores (available on GeForce GTS 450, reasonable basic model, but other cards have up to 1024 cores). I'm not a CUDA guru, I'm playing with it for a few days, but maybe this post could help you not to do the first steps more easily - especially if you're using Gentoo like me ...
