I started off with the original 4.4BSD code, and by iterative modifications I will develop a scheduler that matches the BFS design as specified in http://ck.kolivas.org/patches/bfs/sched-BFS.txt. Last week I added some cpu topology awareness into my scheduler. When choosing an idle cpu for a thread that is waking up, I prefer idle cpus that are in the cpu group of the last cpu where the thread was running. I have also been working on a live cd that will contain my scheduler. You can find more info at my project blog page http://rudot.blog.com/. Next week I will firstly finish the work on the live cd. Then I will run the similar benchmarks as I run at the beginning of the project. I will publish the results at my project blog page. rudo
