In computing, scheduling is the method by which work specified by some means is assigned to resources that complete the work. The work may be virtual computation elements such as threads, processes or data flows, which are in turn scheduled onto hardware resources such as processors, network links or expansion cards.
A scheduler is what carries out the scheduling activity. Schedulers are often implemented so they keep all computer resources busy (as in load balancing), allow multiple users to share system resources effectively, or to achieve a target quality of service. Scheduling is fundamental...
The Completely Fair Scheduler (CFS) is a process scheduler which was merged into the 2.6.23 (October 2007) release of the Linux kernel and is the default scheduler. It handles CPU resource allocation for executing processes, and aims to maximize overall CPU utilization while also maximizing interactive performance.
Con Kolivas's work with CPU scheduling, most significantly his implementation of "fair scheduling" named Rotating Staircase Deadline, inspired Ingo Molnár to develop his CFS, as a replacement for the earlier O(1) scheduler, crediting Kolivas in his announcement.
In contrast to the previous...
The software utility Cron is a time-based job scheduler in Unix-like computer operating systems. People who set up and maintain software environments use cron to schedule jobs (commands or shell scripts) to run periodically at fixed times, dates, or intervals. It typically automates system maintenance or administration—though its general-purpose nature makes it useful for things like downloading files from the Internet and downloading email at regular intervals. The origin of the name cron is from the Greek word for time, χρόνος (chronos). (Ken Thompson, author of cron, has confirmed this in a...
Lyoto Carvalho Machida (Portuguese pronunciation: [liˈotu maˈʃidɐ]; 町田龍太) (born May 30, 1978) is a Brazilian mixed martial artist who currently competes in the middleweight division of the Ultimate Fighting Championship. He is a former UFC Light Heavyweight Champion.
== Early lifeEdit ==
Lyoto was born in Salvador, Brazil, as the third son of the highly ranked head of the Brazilian branch of the Japan Karate Association, Shotokan karate master Yoshizo Machida (町田嘉三). Yoshizo moved to Brazil from Japan when he was 22 years old, where he met and married Lyoto's mother, Ana Claudia, who is o...
When we talked about hybridization in bonding in my materials science class, we went over how in atoms like carbon, the s and the p orbitals can combine to make hybrid orbitals that are degenerate in energy.
The class requires no background in quantum mechanics but I have a bit myself, and I'm ...
