EEVDF was first described in the 1995 paper "Earliest Eligible Virtual Deadline First : A Flexible and Accurate Mechanism for Proportional Share Resource Allocation" by Ion Stoica and Hussein Abdel-Wahab. [2] It uses notions of virtual time, eligible time, virtual requests and virtual deadlines for determining scheduling priority. [1]
Location of the process scheduler in a simplified structure of the Linux kernel. SCHED_DEADLINE is a CPU scheduler available in the Linux kernel since version 3.14, [1] [2] based on the earliest deadline first (EDF) and constant bandwidth server (CBS) [3] algorithms, supporting resource reservations: each task scheduled under such policy is associated with a budget Q (aka runtime), and a ...
In 2016, the Linux scheduler was patched for better multicore performance, based on the suggestions outlined in the paper, "The Linux Scheduler: A Decade of Wasted Cores". [ 9 ] In 2023, a new scheduler based on earliest eligible virtual deadline first scheduling (EEVDF) was being readied to replace CFS. [ 10 ]
The AQuoSA project constitutes a modification to the Linux kernel enriching the process scheduler with EDF scheduling capabilities. The timing of the scheduling cannot be as precise as in the case of the above hard real-time Operating Systems, yet it is sufficiently precise so as to greatly enhance predictability, and thus fulfill the real-time ...
The new EEVDF process scheduler was merged. ... Named Linux for Workgroups after the 20 years of Windows 3.11 [246] 3.10 30 June 2013 [247] 3.10.108 [248] Willy ...
The O(n) scheduler [1] is the scheduler used in the Linux kernel between versions 2.4 and 2.6. Since version 2.6.0, it has been replaced by the O(1) scheduler and in 2.6.23 by the Completely Fair Scheduler (CFS), which itself was replaced by the current Earliest eligible virtual deadline first (EEVDF) in 6.6.
The location of process schedulers in a simplified structure of the Linux kernel. The Brain Fuck Scheduler (BFS) is a process scheduler designed for the Linux kernel in August 2009 based on earliest eligible virtual deadline first scheduling (EEVDF), [2] as an alternative to the Completely Fair Scheduler (CFS) and the O(1) scheduler.

An ELF file has two views: the program header shows the segments used at run time, whereas the section header lists the set of sections.. In computing, the Executable and Linkable Format [2] (ELF, formerly named Extensible Linking Format) is a common standard file format for executable files, object code, shared libraries, and core dumps.
