The Really Fair Scheduler

Posted by kdawson on from the not-over-till-it's-over dept.

derrida writes "During the many threads discussing Ingo Molnar's recently merged Completely Fair Scheduler, Roman Zippel has repeatedly questioned the complexity of the new process scheduler. In a recent posting to the Linux Kernel mailing list he offered a simpler scheduler named the 'Really Fair Scheduler' saying, 'As I already tried to explain previously CFS has a considerable algorithmic and computational complexity. This patch should now make it clearer, why I could so easily skip over Ingo's long explanation of all the tricks CFS uses to keep the computational overhead low — I simply don't need them.'"

      Still waiting for Steve Jobs' "Insanely Fair Scheduler." Wouldn't that be named something more like iFS or iSched?

      God forbid we drop the lower-case I naming convention. It stands for "interwebs compatible".

    In which no process gets any resources at all. I've also been considering a quantum scheduler, in which each CPU cycle is assigned to every process simultaneously.

    Let's just go back to cooperative multitasking like Mac OS where everything was simple.

    Of course, there's the companion "pork barrel scheduler" which randomly spawns useless processes in order to take time from those that deserve it.

    How about the Scarbrough Fair Scheduler, that allocates Parsley, Sage, Rosemary and Thymeslices.
