Hi, the goal of my project is to implement a BFS - like scheduler into the FreeBSD. 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 finished the initial benchmarking - I have run sysbench benchmarks on a 8 cpu machine. Then I modified the mapping of threads to the priority queues according to their priority. BFS uses a single queue for timesharing threads and a single queue for idle threads. I keed the number of queues at 64. I will write more about it at my blog http://rudot.blog.com/ tomorrow. Next week I will implement a virtual deadline for the time sharing threads. rudo
