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 was dealing with one bug that caused sometimes kernel panics. I noticed the panics when running my scheduler on amd64. I have fixed it. I will write more about this bug at my project blog page at http://rudot.blog.com This week I am working on per process CPU accounting. rudo
