  2. Scheduling (computing) - Wikipedia

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

    The scheduler is an operating system module that selects the next jobs to be admitted into the system and the next process to run. Operating systems may feature up to three distinct scheduler types: a long-term scheduler (also known as an admission scheduler or high-level scheduler), a mid-term or medium-term scheduler, and a short-term scheduler.

  3. Completely Fair Scheduler - Wikipedia

    en.wikipedia.org/wiki/Completely_Fair_Scheduler

    Originally invented for packet networks, fair queuing had been previously applied to CPU scheduling under the name stride scheduling. CFS is the first implementation of a fair queuing process scheduler widely used in a general-purpose operating system. [5]

  4. Multithreading (computer architecture) - Wikipedia

    en.wikipedia.org/wiki/Multithreading_(computer...

    From the software standpoint, hardware support for multithreading is more visible to software, requiring more changes to both application programs and operating systems than multiprocessing. Hardware techniques used to support multithreading often parallel the software techniques used for computer multitasking. Thread scheduling is also a major ...

  5. Worst-case execution time - Wikipedia

    en.wikipedia.org/wiki/Worst-case_execution_time

    However, on modern hardware, especially multi-core, other tasks in the system will impact the WCET of a given task if they share cache, memory lines and other hardware features. Further, task scheduling events such as blocking or to be interruptions should be considered in WCET analysis if they can occur in a particular system. Therefore, it is ...

  6. Computer performance - Wikipedia

    en.wikipedia.org/wiki/Computer_performance

    Because the units of throughput are the reciprocal of the unit for propagation delay, which is 'seconds per message' or 'seconds per output', throughput can be used to relate a computational device performing a dedicated function such as an ASIC or embedded processor to a communications channel, simplifying system analysis.

  7. Maximum throughput scheduling - Wikipedia

    en.wikipedia.org/wiki/Maximum_throughput_scheduling

    Maximum throughput scheduling is a procedure for scheduling data packets in a packet-switched best-effort network, typically a wireless network, in view to maximize the total throughput of the network, or the system spectral efficiency in a wireless network. This is achieved by giving scheduling priority to the least "expensive" data flows in ...

  8. 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).

  9. Interrupt latency - Wikipedia

    en.wikipedia.org/wiki/Interrupt_latency

    Lastly, trying to reduce processor utilization may increase interrupt latency and decrease throughput. Minimum interrupt latency is largely determined by the interrupt controller circuit and its configuration. They can also affect the jitter in the interrupt latency, which can drastically affect the real-time schedulability of the system.
