What is CPU scheduling in Linux?
CPU scheduling in Linux is the method by which the operating system decides which process runs at any given time.
What are the different scheduling algorithms used in Linux?
Linux primarily uses the Completely Fair Scheduler (CFS), but also supports real-time scheduling algorithms like FIFO and Round Robin.
How does the Completely Fair Scheduler work?
CFS aims to allocate CPU time fairly among all processes, using a red-black tree to manage runnable processes.
Can I change the scheduling policy for a process?
Yes, you can change the scheduling policy using the chrt
command or by modifying the process's attributes in the /proc
filesystem.
