'''Yellow Dog Linux''' ('''YDL''') is a discontinued [[free and open-source]] [[operating system]] for high-performance computing on [[multi-core processor]] [[computer architecture]]s, focusing on GPU systems and computers using the [[POWER7]] processor. The original developer was Terra Soft Solutions, which was acquired by [[Fixstars Solutions|Fixstars]] in October 2008.<ref>{{cite web|last=Shoemaker|first=Kristin|title=Terra Soft Solutions Acquired by Fixstars|url=http://ostatic.com/blog/terra-soft-solutions-acquired-by-fixstars|access-date=13 July 2013|date=11 November 2008}}</ref> Yellow Dog Linux was first released in the spring of 1999 for Apple Macintosh PowerPC-based computers.<ref name="linuxfoundation">{{cite web|title=Yellow Dog Linux|date=19 August 1999|url=http://www.linux.com/directory/Distributions/enterprise/yellow-dog-linux|publisher=Linux Foundation|access-date=13 July 2013}}</ref> The last version, Yellow Dog Linux 7,<ref>{{cite web|title=PowerLinux 7R2 Yellow Dog Appliance|url=http://www.fixstars.com/en/hardware/power/ydl7/| archive-url=https://web.archive.org/web/20120714002801/https://www.fixstars.com/en/hardware/power/ydl7/ |archive-date=14 July 2012}}</ref> was released on August 6, 2012.<ref name="distrowatch">{{cite web|title=DistroWatch.com: Yellow Dog Linux|url=http://distrowatch.com/table.php?distribution=yellowdog}}</ref> Yellow Dog Linux lent its name to the popular [[Yellowdog Updater, Modified|YUM]] Linux software updater, derived from YDL's YUP (Yellowdog UPdater) and thus called [[Yellow Dog Updater, Modified|Yellowdog Updater, Modified]].

==Features==
[[Image:Yellow Dog Linux.png|thumb|320px|Screenshot of Yellow Dog Linux Version 6.0 'Pyxis' depicting [[Enlightenment (window manager)|Enlightenment]], the default window manager]]
Yellow Dog Linux is based on [[Red Hat Enterprise Linux]]/[[CentOS]]<ref name="linuxfoundation" /> and relies on the [[RPM Package Manager]].<ref>{{cite book|last=Negus|first=Christopher|title=Linux Bible 2009 Edition|url=https://books.google.com/books?id=Hk74DjrdMlgC&q=Yellow%20Dog%20Linux&pg=PA610|publisher=Wiley Publishing, Inc.|access-date=13 July 2013|year=2009|isbn=9780470459041}}</ref> Its software includes applications such as [[Ekiga]] (a [[Voice over Internet Protocol|voice-over-IP]] and [[videoconferencing]] application), [[GIMP]] (a raster graphics editor), [[Gnash (software)|Gnash]] (a free [[Adobe Flash]] player), [[gThumb]] (an image viewer), the [[Mozilla Firefox]] Web browser, the [[Mozilla Thunderbird]] e-mail and news client, the [[OpenOffice.org]] productivity suite, [[Pidgin (software)|Pidgin]] (an instant messaging and [[Internet Relay Chat|IRC]] client), the [[Rhythmbox]] music player, and the KDE [[Noatun (media player)|Noatun]] and [[Totem (media player)|Totem]] media players.

Starting with YDL version 5.0 'Phoenix', [[Enlightenment (window manager)|Enlightenment]] is the Yellow Dog Linux default desktop environment, although [[GNOME]] and [[KDE]] are also included.

Like other Linux distributions, Yellow Dog Linux supports software development with [[GNU Compiler Collection|GCC]]<ref name="distrowatch" /> (compiled with support for [[C (programming language)|C]], [[C++]], [[Java (programming language)|Java]], and [[Fortran]]), the [[GNU C Library]], [[GNU Debugger|GDB]], [[GLib]], the [[GTK+]] toolkit, [[Python (programming language)|Python]], the [[Qt (toolkit)|Qt]] toolkit, [[Ruby (programming language)|Ruby]] and [[Tcl]]. Standard text editors such as [[Vim (text editor)|Vim]] and [[Emacs]] are complemented with [[Integrated development environment|IDEs]] such as [[Eclipse (software)|Eclipse]] and [[KDevelop]], as well as by graphical debuggers such as [[KDbg]]. Standard document preparation tools such as [[TeX]] and [[LaTeX]] are also included.

Yellow Dog Linux includes software for running a Web server (such as [[Apache HTTP Server|Apache/httpd]], [[Perl]], and [[PHP]]), database server (such as [[MySQL]] and [[PostgreSQL]]), and network server ([[Network File System (protocol)|NFS]] and [[Webmin]]). Additional software is also included for running an enterprise server or a compute server or cluster, although two separate products from Terra Soft Solutions, called Yellow Dog Enterprise Linux (for enterprise servers) and Y-HPC (for compute servers/clusters), were specifically targeted toward those applications.

Although [[Comparison of Linux distributions#Instruction set architecture support|several other Linux distributions support the Power ISA]], Yellow Dog Linux was distinguished for its focus on supporting the Apple Macintosh platform before the [[Mac transition to Intel processors]].<ref>{{cite web|title=Comparison of Distribution|url=http://www.yolinux.com/TUTORIALS/LinuxListOfDistributions.html|access-date=13 July 2013}}</ref> Before this transition, Terra Soft Solutions held the unique distinction of being the only company licensed by [[Apple Inc.|Apple]] to resell Apple computers with Linux pre-installed<ref>{{cite web|title=Terra Soft Ships Apple computers - YDL Pre-Installed |url=http://terrasoftsolutions.com/news/2002-08-08.shtml |access-date=13 July 2013 |date=8 August 2002 |url-status=dead |archive-url=https://web.archive.org/web/20021207090908/http://terrasoftsolutions.com/news/2002-08-08.shtml |archive-date=December 7, 2002 }}</ref> (or for that matter, with any operating system other than [[Mac OS X|Mac OS&nbsp;X]]). Full support for [[AirPort]] (Apple's implementation of the [[IEEE 802.11b-1999]] wireless networking standard), and partial support for AirPort Extreme, are also built into Yellow Dog Linux, as are support for [[Bluetooth]] and support for accessing the Internet over cellular phones.

Following the Mac transition to Intel processors, Yellow Dog Linux retargeted Fedora Core 5.0 and later to support the [[Sony PlayStation 3]] and IBM pSeries platforms extensively, while retaining its longstanding support for PowerPC-based Apple hardware.

==Distribution==
Yellow Dog Linux was sold by Terra Soft Solutions (later [[Fixstars Solutions|Fixstars]]), who also marketed PlayStation 3 consoles,{{cn|date=February 2019}} IBM workstations,<ref>{{cite web|title=Yellow Dog Linux Supports New IBM B50|url=http://www.thefreelibrary.com/Yellow+Dog+Linux+Supports+New+IBM+B50.-a055726179|access-date=13 July 2013|date=13 September 1999 |archive-url=https://web.archive.org/web/20141107032223/https://www.thefreelibrary.com/Yellow+Dog+Linux+Supports+New+IBM+B50.-a055726179 |archive-date=7 November 2014}}</ref> and servers with Yellow Dog Linux pre-installed.<ref>{{cite web|title=Yellow Dog Enterprise Linux for the BCU-100|url=http://pro.sony.com/bbsccms/ext/ZEGO/files/tss-ydl-bcu100.pdf|publisher=Sony|access-date=13 July 2013 |archive-url=https://web.archive.org/web/20180219090940/http://pro.sony.com/bbsccms/ext/ZEGO/files/tss-ydl-bcu100.pdf |archive-date=19 February 2018}}</ref> As is the case with most other Linux distribution vendors, a portion of the revenue from the sale of those boxed distributions went toward development of the operating system and applications, which are made available as source code under various [[Free and open-source software|free and open-source licenses]].

==Notable implementations==
[[Gaurav Khanna (physicist)|Gaurav Khanna]], a professor in the Physics Department at the [[University of Massachusetts Dartmouth|University of Massachusetts, Dartmouth]], built a message-passing based cluster using YDL and 16 [[PlayStation 3]]s. This cluster was the first such to generate published scientific results. Dubbed the "PS3 Gravity Grid", it performs astrophysical simulations of large [[supermassive black hole]]s capturing smaller compact objects.<ref>{{cite web | url = http://gravity.phy.umassd.edu/ps3.html | title= PS3 Gravity Grid | publisher = Gaurav Khanna, Associate Professor, College of Engineering, University of Massachusetts Dartmouth }}</ref> Khanna claimed that the cluster's performance exceeds that of a 100+ Intel Xeon core based traditional Linux cluster on his simulations. The PS3 Gravity Grid received media coverage between 2007 and 2010.<ref>{{cite news | url = https://www.wired.com/techbiz/it/news/2007/10/ps3_supercomputer | title= Astrophysicist Replaces Supercomputer with Eight PlayStation 3s | magazine=Wired | date=17 October 2007}}</ref><ref>{{cite web | url = http://www.computerworld.com/s/article/9043942/PS3_cluster_creates_homemade_cheaper_supercomputer | title= PS3 cluster creates homemade, cheaper supercomputer | date= 24 October 2007 }}</ref><ref>{{cite news | url = https://www.washingtonpost.com/wp-dyn/content/article/2008/12/22/AR2008122201980.html | title= Nothing Escapes the Pull of a PlayStation 3, Not Even a Black Hole | newspaper=The Washington Post | last=Peckham | first=Matt | date=23 December 2008}}</ref><ref>{{cite web | url = http://www.space.com/businesstechnology/090128-playstation3-blackholes.html | title= Playstation 3 Consoles Tackle Black Hole Vibrations| website= [[Space.com]]| date= 28 January 2009}}</ref><ref>{{cite news | url = https://www.npr.org/templates/story/story.php?storyId=100969805 | title= Playstation 3: A Discount Supercomputer?| newspaper= NPR.org}}</ref>
