    Learning About Parallel Programming

    Clearly, multithreaded or parallel programming is growing in importance as the new chip architectures move towards multiple cores and multiple threads rather than merely upping clock cycle times.

    But parallel programming is hard, no doubt about it. It's so much easier to cast a computational problem into a serial, one-step-at-a-time framework than think of it in terms of data distribution over networks of compute nodes.

    So how do you learn parallel programming?

    Luckily there are a number of resources on the web. Here are just a few links
