An OK start

New page

A '''scheduler''' is the [[software]] module in a [[multi-tasking]] system (such as an [[operating system]] with [[process]]es) which decides which computation is to run next when the previous computation gives up (or is forced off, in [[preemptive multi-tasking]]) the [[Central Processing Unit|processor]].

There are many different types of scheduler.

In a large [[time-sharing]] system, [[user]]s are often organized into groups, and the system administrator may be able to set things so that particular groups are guaranteed minimum shares of the machine.

In a [[real-time system]], a scheduler known as a 'deadline scheduler' may be supported; each [[task]] sets a time by which is must run, and the scheduler selects tasks to run in order of their deadlines.
