I’m very glad to announce that the Introductory CUDA article I wrote for RealityFrontier (and that was published by the Linux Journal Magazine) is now available for online reading.
You can access the article here: http://goo.gl/jFz3z; it features an introduction to Parallel Programming using the NVIDIA CUDA technology and some cool screenshots made using a renderer I wrote specifically for representing the concepts being treated in the article.
I can also provide links to the full source code used for the benchmarks, in case you want to have a look at it.
Just drop me a line in the comments. Enjoy!
