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. [3]
A job scheduler is a computer application for controlling unattended background program execution of jobs. [1] This is commonly called batch scheduling , as execution of non-interactive jobs is often called batch processing , though traditional job and batch are distinguished and contrasted; see that page for details.
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.
EDF is an optimal scheduling algorithm on preemptive uniprocessors, in the following sense: if a collection of independent jobs, each characterized by an arrival time, an execution requirement and a deadline, can be scheduled (by any algorithm) in a way that ensures all the jobs complete by their deadline, the EDF will schedule this collection ...

Task Scheduler (formerly Scheduled Tasks) [1] is a job scheduler in Microsoft Windows that launches computer programs or scripts at pre-defined times or after specified time intervals. [2] [3] Microsoft introduced this component in the Microsoft Plus! for Windows 95 as System Agent. [4] Its core component is an eponymous Windows service. [5]
The Completely Fair Scheduler (CFS) was a process scheduler that was merged into the 2.6.23 (October 2007) release of the Linux kernel. It was the default scheduler of the tasks of the SCHED_NORMAL class (i.e., tasks that have no real-time execution constraints) and handled CPU resource allocation for executing processes , aiming to maximize ...
