I liked the way the content is presented. I had Parallel Computing as one of my elective this semester, and the subject isn't kool any more when you dive into it. Parallel Computing is tough IMHO and it takes some brainstorming to solve even the basic problems like computing prime numbers or sparse matrix multiplication.
Also we use OpenCL, which itself is quite a complicated deal. ( TBB, OpenMP are simpler ). The tutorial makes the basics clear as well as the post have an aesthetic feel to it. All in all - a nice read.
