IRIX is a computer operating system developed by Silicon Graphics, Inc. (SGI) to run natively on their 32- and 64-bit MIPS architecture workstations and servers. Based on UNIX System V with BSD extensions, it is capable of extremely long uptimes, and its XFS file system is regarded as one of the most advanced journaling file systems in the industry.[citation needed] Image File history File links This is a lossless scalable vector image. ...

The current major version of IRIX is IRIX 6.5 which was released in May 1998. New minor versions are released every quarter. Through version 6.5.22, there were two branches of each release: a maintenance release that included only fixes to the original IRIX 6.5 code, and a feature release that included improvements and enhancements. An overlay upgrade from 6.5.x to the 6.5.22 maintenance release is available for free download, while version 6.5.23 and higher require an active Silicon Graphics support contract, despite only running on Silicon Graphics hardware.

History

The IRIX name was first used around the time of release 3.0 of the operating system for SGI's IRIS 4D series of workstations and servers, in 1988. Previous releases were identified only by the release number prefixed by "4D1-", eg. "4D1-2.2". The 4D1- prefix continued to be used in official documentation to prefix IRIX release numbers.


IRIX 3.x was based on UNIX System V Release 3 with 4.3BSD enhancements, and incorporated the 4Sight windowing system, based on NeWS and IRIS GL. SGI's own Extent File System (EFS) replaced the System V filesystem. It has been suggested that Traditional Unix be merged into this article or section. ... Berkeley Software Distribution (BSD, sometimes called Berkeley Unix) is the Unix derivative distributed by the University of California, Berkeley starting in the 1970s. ... 4Sight is the default Window Manager for Silicon Graphics UNIX variant IRIX in versions 3. ... A windowing system is a graphical user interface (GUI) which uses the window as one of its primary metaphors. ... For other uses, see News (disambiguation). ... OpenGL (Open Graphics Library) is a specification defining a cross-language cross-platform API for writing applications that produce 3D computer graphics (and 2D computer graphics as well). ... There is also a (different) filing system called EFS under Microsoft Windows 2000. ...


IRIX 4.0, released in 1991, replaced 4Sight with the X Window System (X11R4), the 4Dwm window manager providing a similar look and feel to 4Sight. “X11” redirects here. ... 4dwm is a window manager normally used on Silicon Graphics workstations running IRIX. 4dwm is derived from the older mwm window manager and uses the Motif widget toolkit on top of the X Window System found on most Unix systems. ... A window manager is computer software that controls the placement and appearance of windows within a windowing system in a graphical user interface. ...


IRIX 5.0, released in 1993, incorporated certain features of UNIX System V Release 4, including ELF-format executables. IRIX 5.3 introduced the XFS journaling file system. In computing, the Executable and Linking Format (ELF, formerly called Extensible Linking Format) is a common standard file format for executables, object code, shared libraries, and core dumps. ... XFS is a high-performance journaling file system created by Silicon Graphics for their IRIX operating system. ... A journaling (or journalling) file system is a file system that logs changes to a journal (usually a circular log in a specially-allocated area) before actually writing them to the main file system. ...


In 1994, IRIX 6.0 added support for the 64-bit MIPS R8000 processor, but was otherwise similar to IRIX 5.2. Later 6.x releases supported other members of the MIPS processor family in 64-bit mode. IRIX 6.3 was released for the SGI O2 workstation only. IRIX 6.4 improved multiprocessor scalability for the Octane, Origin 2000, and Onyx2 systems. The Origin 2000 and Onyx2 IRIX 6.4 was marketed as "Cellular IRIX", although it only incorporated some features from the original Cellular IRIX distributed operating system project. IRIX 6.4 had severe reliability issues, limiting its adoption. IRIX development stabilized with IRIX 6.5, released in 1998. The current version of IRIX is 6.5.30, released in August 2006.
