What Type of Scheduling Does Linux Use?

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.

Does Linux use round robin scheduling?

Real Time Scheduling Processes

Linux implements FCFS and Round Robin real time scheduling classes. The scheduler always runs the process with the highest priority. Among processes of equal priority, Linux runs the process that has been waiting the longest.

Does Linux scheduler threads or processes?

3 Answers. The Linux kernel scheduler is actually scheduling tasks, and these are either threads or (single-threaded) processes. A process is a non-empty finite set (sometimes a singleton) of threads sharing the same virtual address space (and other things like file descriptors, working directory, etc etc…).
