Features
IRIX 6 was compliant with UNIX System V Release 4, UNIX 95 and POSIX (including 1e/2c draft 15 ACLs and Capabilities).
IRIX had strong support for real-time disk and graphics I/O. IRIX was one of the first Unix versions to feature a graphical user interface for the main desktop environment. IRIX was widely used in the computer animation industry and for scientific visualization due to its once-large application base.
IRIX was a leader in Symmetric Multi-Processing (SMP), scalable from 1 to greater than 1024 processors with a single system image.
IRIX used the Indigo Magic Desktop, which by default used the 4Dwm X window manager with a custom look designed using the Motif widget toolkit.
IRIX used the MIPSPro 7.4 Compiler for both its front end and back end. The compiler was designed to support parallel POSIX programming in C/C++, Fortran 77/90, and Ada. The Workshop GUI IDE was used for development. Other tools include Speedshop for performance tuning, and Performance Co-Pilot.
IRIX also supported OpenGL for graphics chips and Image processing libraries.

Famous quotes containing the word features:
““It looks as if
Some pallid thing had squashed its features flat
And its eyes shut with overeagerness
To see what people found so interesting
In one another, and had gone to sleep
Of its own stupid lack of understanding,
Or broken its white neck of mushroom stuff
Short off, and died against the windowpane.””
—Robert Frost (1874–1963)
“Art is the child of Nature; yes,
Her darling child, in whom we trace
The features of the mother’s face,
Her aspect and her attitude.”
—Henry Wadsworth Longfellow (1807–1882)
“However much we may differ in the choice of the measures which should guide the administration of the government, there can be but little doubt in the minds of those who are really friendly to the republican features of our system that one of its most important securities consists in the separation of the legislative and executive powers at the same time that each is acknowledged to be supreme, in the will of the people constitutionally expressed.”
—Andrew Jackson (1767–1845)
