In computing, scheduling is the action of assigning resources to perform tasks. The resources may be processors, network links or expansion cards. The tasks may be threads, processes or data flows. The scheduling activity is carried out by a process called scheduler. Schedulers are often designed so as to keep all … See more A scheduler may aim at one or more goals, for example: • maximizing throughput (the total amount of work completed per time unit); • minimizing wait time (time from work becoming ready until the first point it … See more A scheduling discipline (also called scheduling policy or scheduling algorithm) is an algorithm used for distributing resources among … See more • Activity selection problem • Aging (scheduling) • Atropos scheduler • Automated planning and scheduling See more • Operating Systems: Three Easy Pieces by Remzi H.

Web5.1.3. Preemptive Scheduling. CPU scheduling decisions take place under one of four conditions: When a process switches from the running state to the waiting state, such as for an I/O request or invocation of the wait( ) system call. When a process switches from the running state to the ready state, for example in response to an interrupt. WebFeb 5, 2024 · A scheduling class specifies which scheduling policy applies to which type of process. Completely fair scheduling (CFS), which became part of the Linux 2.6.23 kernel in 2007, is the scheduling class for normal (as opposed to real-time) processes and therefore is named SCHED_NORMAL. CFS is geared for the interactive applications …
