Tru64 UNIX is a 64-bit UNIX operating system for the Alpha microprocessor architecture, currently owned by Hewlett-Packard (HP). Year 2006 ( MMVI) was a Common year starting on Sunday of the Gregorian calendar. In the Philosophy of language, a natural language (or ordinary language) is a Language that is spoken or written in phonemic-alphabetic or phonemically-related Alpha, originally known as Alpha AXP, was a 64-bit Reduced instruction set computer (RISC Instruction set architecture (ISA developed In Computer science, the kernel is the central component of most computer Operating systems (OS Hybrid kernel is a kernel architecture based on combining aspects of Microkernel and Monolithic kernel architectures used in Computer The user interface (or Human Computer Interface) is the aggregate of means by which people&mdash the users '&mdash interact with the System A software license (or software licence in commonwealth usage is a Legal instrument governing the usage or redistribution of copyright protected software Proprietary software is Computer software on which the producer has set restrictions on use private modification copying, or republishing. '64-bit' CPUs have existed in Supercomputers since the 1960s and in RISC -based workstations and servers since the early 1990s. Unix (officially trademarked as UNIX, sometimes also written as Unix with Small caps) is a computer An operating system (commonly abbreviated OS and O/S) is the software component of a Computer system that is responsible for the management and coordination Alpha, originally known as Alpha AXP, was a 64-bit Reduced instruction set computer (RISC Instruction set architecture (ISA developed A microprocessor incorporates most or all of the functions of a Central processing unit (CPU on a single Integrated Previously, Tru64 UNIX was a product of Compaq, and before that, Digital Equipment Corporation (DEC), where it was known as Digital UNIX (formerly DEC OSF/1 AXP). Compaq Computer Corporation was an American Personal computer company founded in 1982 and is now a brand name of Hewlett-Packard. Digital Equipment Corporation was a pioneering American company in the Computer industry

As its original name suggests, Tru64 UNIX is based on the OSF/1 operating system. DEC's previous UNIX product was known as Ultrix and was based on BSD UNIX. Ultrix (officially all-caps ULTRIX) was the brand name of Digital Equipment Corporation 's (DEC native Unix systems

It is unusual among common commercial UNIX implementations as it is built on top of the Mach kernel developed at Carnegie Mellon University. Mach is an Operating system Microkernel developed at Carnegie Mellon University to support operating system research primarily distributed and parallel Carnegie Mellon University (also known as CMU) is a private Research University in Pittsburgh, Pennsylvania, United (Other commercial UNIX implementations built on top of the Mach kernel are NeXTSTEP, MkLinux, and Mac OS X. Nextstep was the original object-oriented, multitasking Operating system that NeXT Computer developed to run on its range of proprietary computers MkLinux is an Open source computer Operating system started by the OSF Research Institute and Apple Computer in February 1996 to port Linux Mac OS X (mæk oʊ ɛs tɛn is a line of computer Operating systems developed marketed and sold by Apple Inc, the latest of which is pre-loaded on all currently )

Tru64 UNIX requires the SRM boot firmware found on Alpha-based computer systems. The SRM firmware (also called the SRM console) is the boot Firmware written by Digital Equipment Corporation (DEC for computer systems based on the In Computing, firmware is a computer program that is Embedded in a hardware device for example a Microcontroller.

In 1988, during the so-called "Unix wars", DEC joined with IBM, Hewlett-Packard, and others to form the Open Software Foundation (OSF) to develop a version of Unix. Year 1988 ( MCMLXXXVIII) was a Leap year starting on Friday (link displays 1988 Gregorian calendar) The Unix wars were the struggles between Vendors of the Unix Computer Operating system in the late 1980s and early 1990s to set the standard for International Business Machines Corporation abbreviated IBM and nicknamed "Big Blue", is a multinational Computer Technology The Open Software Foundation ( OSF) was an organization founded in 1988 to create an Open standard for an implementation of the Unix operating Dubbed OSF/1, the aim was to compete with System V Release 4 from AT&T and Sun Microsystems, and it has been argued that a primary goal was for the operating system to be free of AT&T intellectual property. Unix System V, commonly abbreviated SysV (and usually pronounced though rarely written as System 5 was one of the versions of the Unix Operating system Before proposing a merge request please see Talk and see if the merger you propose has recently been made and Sun Microsystems Inc ( is a multinational vendor of Computers computer components Computer software, and Information technology services ^[1] The fact that OSF/1 was one of the first operating systems to use the Mach kernel is cited as support of this assertion. Digital also strongly promoted OSF/1 for real-time applications, and with traditional UNIX implementations at the time providing poor real-time support at best, the real-time and multi-threading support was heavily dependent on the Mach kernel. In Computer science, real-time computing (RTC is the study of hardware and software systems that are subject to a "real-time constraint"—i A thread in Computer science is short for a thread of execution. It also incorporated a large part of the BSD kernel (based on the 4. 3-Reno release) to provide Unix compatibility. OSF/1 was envisaged to be the third major branch of the Unix family tree, after System V and BSD. Unix System V, commonly abbreviated SysV (and usually pronounced though rarely written as System 5 was one of the versions of the Unix Operating system

DEC's original release of OSF/1 (DEC OSF/1 V1. 0) was in January 1992 for their line of MIPS-based DECstation workstations, ^[2] however this was never a fully supported product and was cancelled before the end of the year. Year 1992 ( MCMXCII) was a Leap year starting on Wednesday (link will display full 1992 Gregorian calendar) MIPS (originally an acronym for Microprocessor without Interlocked Pipeline Stages) is a RISC microprocessor architecture developed by MIPS Technologies The DECstation was a brand of computers used by DEC, and refers to three distinct lines of computer systems&mdashthe first released in 1978 as a Word processing DEC ported OSF/1 to their new Alpha AXP platform (as DEC OSF/1 AXP), and this was the first version (V1. Alpha, originally known as Alpha AXP, was a 64-bit Reduced instruction set computer (RISC Instruction set architecture (ISA developed 2) of what is most commonly referred to as OSF/1. OSF/1 AXP was a full 64-bit operating system and the native UNIX implementation for the Alpha architecture. From OSF/1 AXP V2. 0 onwards, UNIX System V compatibility was also integrated into the system. Unix System V, commonly abbreviated SysV (and usually pronounced though rarely written as System 5 was one of the versions of the Unix Operating system

Other vendors

HP also worked on a product based on OSF/1, designed for early versions of their PA-RISC workstations, but this project failed due to the complex nature of the hardware. PA-RISC is a Microprocessor architecture developed by Hewlett-Packard 's Systems & VLSI Technology Operation.

Apple Computer intended to base A/UX 4. Apple Inc, ( formerly Apple Computer Inc, is an American Multinational corporation with a focus on designing and manufacturing Consumer electronics A/UX (from A pple U ni' x') was Apple Computer 's implementation of the Unix Operating system for some of their Macintosh 0 for their PowerPC-based Macintoshes on OSF/1, ^[3] but the project was cancelled. PowerPC is a RISC Instruction set architecture created by the 1991 Apple – IBM – Motorola alliance known as AIM

IBM used OSF/1 as the basis of the AIX/ESA operating system for System/370 and System/390 mainframes. The IBM System/370 (often S/370) was a model range of IBM mainframes announced on June 30, 1970 ESA/390 (Enterprise Systems Architecture/390 was introduced in September 1990 and is IBM 's last 31-bit -address/ 32-bit -data mainframe computing ^[4]

OSF/1 was also ported by Kendall Square Research to their proprietary processor architecture used in the KSR1 supercomputer. Kendall Square Research (KSR was a Supercomputer company headquartered originally in Kendall Square in Cambridge Massachusetts in 1986 near MIT. A supercomputer is a Computer that is at the frontline of processing capacity particularly speed of calculation (at the time of its introduction

In 1994, after AT&T had sold UNIX System V to Novell and the rival Unix International consortium had disbanded, the Open Software Foundation ceased funding of research and development of OSF/1. Year 1994 ( MCMXCIV) was a Common year starting on Saturday (link will display full 1994 Gregorian calendar) Novell Inc ( is a global Software Corporation based in the United States specializing in enterprise operating systems such as SUSE Unix International or UI was an association created in 1988 to promote open standards especially the Unix Operating system.

OSF/1 AD

OSF/1 AD (Advanced Development) was a distributed version of OSF/1 developed for massively parallel supercomputers. Parallel computing is a form of computation in which many instructions are carried out simultaneously operating on the principle that large problems can often Massively parallel is a description which appears in computer science life science medical diagnostics and other fields Variants of OSF/1 AD were used on several such systems, including the Intel Paragon XP/S and ASCI Red, Convex Exemplar SPP-1200 (as SPP-UX) and the Hitachi SR2201 (as HI-UX MPP). The Intel Paragon was a series of Massively parallel Supercomputers produced by Intel. ASCI Red or ASCI Option Red, was a Supercomputer installed at Sandia National Laboratories, located in Albuquerque New Mexico. Convex Computer was a company that produced a number of vector Minisupercomputers Supercomputers for small-to-medium-sized businesses () is a Multinational corporation specializing in high-technology and services headquartered in Marunouchi Itchome Chiyoda, Tokyo, Japan.

Digital UNIX

In 1995, starting with release 3. 2, DEC renamed DEC OSF/1 AXP to Digital UNIX to reflect its conformance with the X/Open Single UNIX Specification. X/Open Company Ltd was a Consortium founded by several European UNIX systems manufacturers in 1984 to identify and promote Open standards in the field The Single UNIX Specification ( SUS) is the collective name of a family of standards for Computer Operating systems to qualify for the name " Unix ^[5]

Tru64 UNIX

After Compaq's purchase of DEC in early 1998, with the release of version 4. Year 1998 ( MCMXCVIII) was a Common year starting on Thursday (link will display full 1998 Gregorian calendar) 0F, Digital UNIX was renamed to Tru64 UNIX to emphasise its 64-bit-clean nature and de-emphasise the Digital brand.

In April 1999, Compaq announced that Tru64 UNIX 5. 0 successfully ran on Intel's IA-64 simulator. Itanium is the brand name for 64-bit Intel Microprocessors that implement the Intel Itanium architecture (formerly called IA-64) ^[6] However, this port was cancelled a few months later. ^[7]

Current status

With their purchase of Compaq in 2002, HP announced their intention to migrate many of Tru64 UNIX's more innovative features (including its AdvFS file system, Trucluster, and LSM) to HP-UX, HP's existing Unix OS. See also 2002 (disambiguation Year 2002 ( MMII) was a Common year starting on Tuesday of the Gregorian calendar. AdvFS, also known as Tru64 Unix Advanced File System, is a File system developed in the late 1980s to mid 1990s by Digital Equipment Corporation for their In Computing, a file system (often also written as filesystem) is a method for storing and organizing Computer files and the data they contain to make HP-UX (Hewlett Packard UniX is Hewlett-Packard 's proprietary implementation of the Unix Operating system, based on System V (initially In December 2004, HP announced a change of plan; they would instead use the Veritas file system and abandon the rest of the Tru64 advanced features. "MMIV" redirects here For the Modest Mouse album see " Baron von Bullshit Rides Again " The VERITAS File System, (or VxFS, called JFS and OJFS in HP-UX) is an extent -based File system. In the process, many of the remaining Tru64 developers were laid off. Layoff is the temporary suspension or permanent Termination of employment of an Employee or (more commonly a group of employees for Business reasons ^[8]

In July 2007, HP stated that they would continue to support Tru64 UNIX until at least 2012, with the next maintenance release, 5. 1B-5, planned for the second half of 2008. ^[9]
