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]
The real-time scheduler developed in the context of the IRMOS Archived 2018-10-10 at the Wayback Machine European Project is a multi-processor real-time scheduler for the Linux kernel, particularly suitable for temporal isolation and provisioning of QoS guarantees to complex multi-threaded software components and also entire virtual machines.
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 ...
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. [3]
He has also written a benchmarking tool called ConTest [10] that can be used to compare the performance of different kernel versions. [11] On 31 August 2009, Kolivas posted a new scheduler called BFS (Brain Fuck Scheduler). [12] It is designed for desktop use and to be very simple (hence it may not scale well to machines with many CPU cores).
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 Since version 2.6.0, it has been replaced by the O(1) scheduler and in 2.6.23 by the Completely Fair Scheduler (CFS), which itself was replaced by the current Earliest eligible virtual deadline first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 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.
The Slurm Workload Manager, formerly known as Simple Linux Utility for Resource Management (SLURM), or simply Slurm, is a free and open-source job scheduler for Linux and Unix-like kernels, used by many of the world's supercomputers and computer clusters.
