Fair-share scheduling is a scheduling algorithm for computer operating systems in which the CPU usage is equally distributed among system users or groups, as opposed to equal distribution of resources among processes. [1]
Learn about the different types of schedulers in computing, such as process, long-term, medium-term and short-term schedulers, and their functions and goals. Find out how schedulers assign resources to perform tasks, balance throughput, latency, fairness and deadlines, and manage I/O and network traffic.
Round-robin scheduling is a time-sharing algorithm that assigns equal time slots to each process or data flow in circular order. It is used for process and network scheduling in computing, and can achieve fairness and efficiency under certain conditions.
For scheduling, the scheduler always starts picking up processes from the head of the highest-level queue. Only if the highest-level queue has become empty will the scheduler take up a process from the next lower-level queue. The same policy is implemented for picking up in the subsequent lower-level queues.
Input/output (I/O) scheduling is the method that computer operating systems use to decide in which order I/O operations will be submitted to storage volumes. I/O scheduling is sometimes called disk scheduling .
Cooperative multitasking, also known as non-preemptive multitasking, is a style of computer multitasking in which processes voluntarily yield control to other processes. Learn about its usage, advantages, problems and contrast with preemptive multitasking.
The Completely Fair Scheduler (CFS) is a process scheduler for Linux kernel that aims to maximize CPU utilization and interactive performance. It uses per-CPU run queues, red-black trees, and a weighted fair queuing algorithm to allocate CPU time to tasks.
In computer science, gang scheduling is a scheduling algorithm for parallel systems that schedules related threads or processes to run simultaneously on different processors. Usually these will be threads all belonging to the same process, but they may also be from different processes, where the processes could have a producer-consumer ...
