I would say look for small things people do which are CPU intensive. One example is sorting -- it can be parallelized fairly well and yet sorting 10_000_000 elements still takes long enough to be worth parallelizing.
If you want examples of working parallel sort etc you can look in the 'Futurism' library that I wrote when exploring Futures for D a few years ago, it's on dsource. Feel free to use whatever you find in there... There might be some other examples but I don't remember off hand. Kevin
