  2. Dynamic priority scheduling - Wikipedia

    en.wikipedia.org/wiki/Dynamic_priority_scheduling

    Dynamic priority scheduling is a type of scheduling algorithm in which the priorities are calculated during the execution of the system. The goal of dynamic priority scheduling is to adapt to dynamically changing progress and to form an optimal configuration in a self-sustained manner.

  3. Earliest deadline first scheduling - Wikipedia

    en.wikipedia.org/wiki/Earliest_deadline_first...

    Earliest deadline first (EDF) or least time to go is a dynamic priority scheduling algorithm used in real-time operating systems to place processes in a priority queue. Whenever a scheduling event occurs (task finishes, new task released, etc.) the queue will be searched for the process closest to its deadline.

  4. Earliest eligible virtual deadline first scheduling - Wikipedia

    en.wikipedia.org/wiki/Earliest_eligible_virtual...

    It uses notions of virtual time, eligible time, virtual requests and virtual deadlines for determining scheduling priority. [1] It has the property that when a job keeps requesting service, the amount of service obtained is always within the maximum quantum size of what it is entitled.

  5. Scheduling (computing) - Wikipedia

    en.wikipedia.org/wiki/Scheduling_(computing)

    For example, Windows NT/XP/Vista uses a multilevel feedback queue, a combination of fixed-priority preemptive scheduling, round-robin, and first in, first out algorithms. In this system, threads can dynamically increase or decrease in priority depending on if it has been serviced already, or if it has been waiting extensively.

  6. Least slack time scheduling - Wikipedia

    en.wikipedia.org/wiki/Least_slack_time_scheduling

    Least slack time (LST) scheduling is an algorithm for dynamic priority scheduling. It assigns priorities to processes based on their slack time. Slack time is the amount of time left after a job if the job was started now. This algorithm is also known as least laxity first.

  7. Completely Fair Scheduler - Wikipedia

    en.wikipedia.org/wiki/Completely_Fair_Scheduler

    The algorithm puts parent processes in the same task group as child processes. [7] (Task groups are tied to sessions created via the setsid() system call. [8]) This solved the problem of slow interactive response times on multi-core and multi-CPU systems when they were performing other tasks that use many CPU-intensive threads in those tasks.

  8. Rate-monotonic scheduling - Wikipedia

    en.wikipedia.org/wiki/Rate-monotonic_scheduling

    In computer science, rate-monotonic scheduling (RMS) [1] is a priority assignment algorithm used in real-time operating systems (RTOS) with a static-priority scheduling class. [2] The static priorities are assigned according to the cycle duration of the job, so a shorter cycle duration results in a higher job priority.

  9. Round-robin scheduling - Wikipedia

    en.wikipedia.org/wiki/Round-robin_scheduling

    A Round Robin preemptive scheduling example with quantum=3. Round-robin (RR) is one of the algorithms employed by process and network schedulers in computing. [1] [2] As the term is generally used, time slices (also known as time quanta) [3] are assigned to each process in equal portions and in circular order, handling all processes without priority (also known as cyclic executive).
