In 1994, IRIX 6.0 added support for the 64-bit MIPS R8000 processor, but is otherwise similar to IRIX 5.2. Later 6.x releases support other members of the MIPS processor family in 64-bit mode. IRIX 6.3 was released for the SGI O2 workstation only. [7] IRIX 6.4 improved multiprocessor scalability for the Octane, Origin 2000, and Onyx2 systems.
The Indigo was designed to run IRIX, SGI's version of Unix. [2] The Indigos with R3000 processors are supported up to IRIX version 5.3, and Indigo equipped with an R4000 or R4400 processor can run up to IRIX 6.5.22. Additionally, the free Unix-like operating system NetBSD has support for both the IP12 and IP20 Indigos as part of the sgimips ...
The SGI Octane with IMPACT-class graphics was first supported by IRIX version 6.4. VPro-class graphics have been supported since IRIX version 6.5.10 for V6 and V8, with V10 and V12 graphics supported as of 6.5.11 (or 6.5.10 with a special driver patch). Linux and OpenBSD have had support.
The IRIX® operating system is the leading technical high-performance 64-bit operating system based on industry-standard UNIX®. IRIX® 6.5 offers system scalability and binary compatibility across the MIPS® processor-based family of platforms and is compliant with UNIX® System V Release 4 and The Open Group's many standards, including UNIX ...
IRIX Interactive Desktop has two primary components: the System Manager and the Toolchest. The System Manager is the main utility for desktop and system configuration. The Toolchest is a menu (normally located on the desktop) that shows which applications are installed on a particular Silicon Graphics workstation.
The Fuel has four 64-bit 3.3V PCI slots for expansion, two of which run at 33 MHz and two of which run at 66 MHz. The system also has two internal Ultra160 SCSI busses, with space for two internal 5.25" devices and three internal hard disks. The Fuel usually shipped with 10,000 rpm SCSI disks, but it can take good advantage of 15,000 rpm models ...
ICE operates on eight 16-bit or sixteen 8-bit integers, [4] but still provides a significant amount of computational power which enables the O2 to do video decoding and audio tasks that would require a much faster CPU if done without SIMD instructions. ICE only works with the IRIX operating system, as this is the only system that has drivers ...
Indy was launched with the IRIX 5.1 operating system, [1] by which it is binary-compatible across the entire SGI family. [1] [3] 5.1 does not take full advantage of the hardware due to inadequate memory management. Later in 1993, SGI increased the base specification to 32 MB. IRIX 5.2 and later have much more efficient memory usage. [3]
