Linux Kernel Group Scheduling Feature of CFS
Hello, Completely Fair Scheduler uses group Scheduling. That is every process gets an equal share of CPU time no matter how many threads are there. How to measure that CFS uses Group Scheduling Feature. Which performance tools like time, vmstat will help to prove this. Regards, Suniita
Hello, I want to test the properties of CFS scheduler on a beaglebone. I tested the number of voluntary and involuntary context switches that occur while execution of a program. How to test fairness, throughput, latency. Hello, Completely Fair Scheduler uses group Scheduling. That is every process gets an equal share of CPU time no matter how many threads are there.

This is extremely documented and a subject of nearly every graduate school and undergrad OS class and thesis. I don't think your understanding how it works and I suggest you research this FIRST and reviewing the source code PRIOR to coming to the mailing list and begging for help. Also, make sure you search usenet archives. Then if you have a specific question, you can frame a good question.
