Yellow Dog Linux (YDL) is a discontinuedfree and open-sourceoperating system for high-performance computing onmulti-core processorcomputer architectures, focusing on GPU systems and computers using thePOWER7 processor. The original developer was Terra Soft Solutions, which was acquired byFixstars in October 2008.[2] Yellow Dog Linux was first released in the spring of 1999 for Apple Macintosh PowerPC-based computers.[3] The last version, Yellow Dog Linux 7,[4] was released on August 6, 2012.[1] Yellow Dog Linux lent its name to the popularYUM Linux software updater, derived from YDL's YUP (Yellowdog UPdater) and thus calledYellowdog Updater, Modified.
Yellow Dog Linux is based onRed Hat Enterprise Linux/CentOS[3] and relies on theRPM Package Manager.[5] Its software includes applications such asEkiga (avoice-over-IP andvideoconferencing application),GIMP (a raster graphics editor),Gnash (a freeAdobe Flash player),gThumb (an image viewer), theMozilla Firefox Web browser, theMozilla Thunderbird e-mail and news client, theOpenOffice.org productivity suite,Pidgin (an instant messaging andIRC client), theRhythmbox music player, and the KDENoatun andTotem media players.
Starting with YDL version 5.0 'Phoenix',Enlightenment is the Yellow Dog Linux default desktop environment, althoughGNOME andKDE are also included.
Like other Linux distributions, Yellow Dog Linux supports software development withGCC[1] (compiled with support forC,C++,Java, andFortran), theGNU C Library,GDB,GLib, theGTK+ toolkit,Python, theQt toolkit,Ruby andTcl. Standard text editors such asVim andEmacs are complemented withIDEs such asEclipse andKDevelop, as well as by graphical debuggers such asKDbg. Standard document preparation tools such asTeX andLaTeX are also included.
Yellow Dog Linux includes software for running a Web server (such asApache/httpd,Perl, andPHP), database server (such asMySQL andPostgreSQL), and network server (NFS andWebmin). 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.
Althoughseveral other Linux distributions support the Power ISA, Yellow Dog Linux was distinguished for its focus on supporting the Apple Macintosh platform before theMac transition to Intel processors.[6] Before this transition, Terra Soft Solutions held the unique distinction of being the only company licensed byApple to resell Apple computers with Linux pre-installed[7] (or for that matter, with any operating system other thanMac OS X). Full support forAirPort (Apple's implementation of theIEEE 802.11b-1999 wireless networking standard), and partial support for AirPort Extreme, are also built into Yellow Dog Linux, as are support forBluetooth 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 theSony PlayStation 3 and IBM pSeries platforms extensively, while retaining its longstanding support for PowerPC-based Apple hardware.[8][9]
Yellow Dog Linux was sold by Terra Soft Solutions (laterFixstars), who also marketed PlayStation 3 consoles,[citation needed] IBM workstations,[10] and servers with Yellow Dog Linux pre-installed.[11] 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 variousfree and open-source licenses.
Gaurav Khanna, a professor in the Physics Department at theUniversity of Massachusetts, Dartmouth, built a message-passing based cluster using YDL and 16PlayStation 3s. This cluster was the first such to generate published scientific results. Dubbed the "PS3 Gravity Grid", it performs astrophysical simulations of largesupermassive black holes capturing smaller compact objects.[12] 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.[13][14][15][16][17]
