Linux Gets Completely Fair Scheduler

SchedFred writes "KernelTrap is reporting that CFS, Ingo Molnar's Completely Fair Scheduler, was just merged into the Linux kernel. The new CPU scheduler includes a pluggable framework that completely replaces Molnar's earlier O(1) scheduler, and is described to 'model an "ideal, precise multi-tasking CPU" on real hardware. CFS tries to run the task with the "gravest need" for more CPU time. So CFS always tries to split up CPU time between runnable tasks as close to "ideal multitasking hardware" as possible.' The new CPU scheduler should improve the desktop Linux experience, and will be part of the upcoming 2.6.23 kernel."

It also means that tasks which were denied adequate runtime in the past will now be favored over current tasks, to make up for the prior unfairness. :)

Anyone with kids can tell you...

The only way to make it completely fair is to let one thread slice the time up, and let the other thread choose which slice it wants. ;-)
