The differences between Linux IO Schedulers

Filed under
Linux

The Linux kernel input/output scheduler (IO Schedulers) controls the way the kernel handles read/write to disks. Different I/O schedulers may have different impact on certain workloads. Here are the list of available Linux I/O schedulers:

1) Noop

Noop scheduler is the simplest IO scheduler available in the kernel. It does not perform sorting or seek-prevention. It is intended for devices that has no mechanical parts or is capable of random access such as SSD or flash-disk.

2) Anticipatory (AS)

Anticipatory is the default I/O scheduler for Linux kernel (2.6.x) until it was replaced by CFQ. It tries to optimize disk I/O by minimizing disk seeking/head movement whenever possible.

Google reveals nationalities of students in open source-focused Summer of Code 2016

Every summer, many students get excited for some well-deserved time off from studies; well, if their region practices such a vacation, that is. In some cultures, school is year-round. While this is unfortunate from the standpoint of socializing and having fun, it arguably keeps the students on track for great success. For students that are particularly motivated and education-focused, Google hosts its legendary Summer of Code. This program pairs future developers with open source projects. Not only do these young folks learn, but they get to contribute to the projects as well. Today, the search giant shares the nationalities of the students participating in Summer of Code 2016. For the first time ever, Albania has a representative -- woo-hoo! This may surprise you, but the USA is not the most-represented nation. The top country, however, may shock you -- or not. Read more
