sched_ule developers manual

[sarthaksarathi]

I am a student studying my masters at International Institute of Information Technology, Bangalore. We are working on a project called "Temperature Aware variant of FreeBSD" in which the scheduling algorithm has to be changed. Could you please provide the developer's manual for the sched_ule.c file explaining the structures, variables and functions?

Take a look http://www.leidinger.net/FreeBSD/dox/kern/html/dd/d9d/sched__ule_8c_source.html. You may also want to read the wiki/ULE_scheduler (references).

Few structures like cpu_group, cpu_search, cpu_top and their data members are not clearly explained. Is there material which explains all the structures and its members and what is the significance of them?

Next paper is very enlightening: Proportional-Share Scheduling: Implementation and Evaluation in a Widely-Deployed Operating System, by David Petrou and John Milford.

Hope that documentation supported above will help to your project.
