This is a fast and dirty page to provide this small project I worked on last christmas. I adapted the bzip2 source code so that the compression stage will make use multiple cpu's if available (using multi threading). I only tested it in linux, but the results are encouraging, on my dual athlon mp machine I gained nearly a 100% speedup.
This code still needs cleanup, but it is fully functional. If you have questions or comments, feel free to contact me on n.werensteijn@student.utwente.nl.
