How Scheduling Is Done in Linux?

Linux uses a Completely Fair Scheduling (CFS) algorithm, which is an implementation of weighted fair queueing (WFQ). Imagine a single CPU system to start with: CFS time-slices the CPU among running threads. There is a fixed time interval during which each thread in the system must run at least once.

How process scheduling is done in Linux?

Linux scheduling is based on the time-sharing technique already introduced in Section 6.3: several processes run in “time multiplexing” because the CPU time is divided into “slices,” one for each runnable process. Of course, a single processor can run only one process at any given instant.
