HP-UX
HP-UX (from "Hewlett Packard Unix") is a proprietary software, proprietary implementation of the Unix operating system developed by Hewlett Packard Enterprise; current versions support HPE Integrity Servers, based on Intel's Itanium architecture. It is based on Unix System V (initially Unix System III, System III) and first released in 1984. Earlier versions of HP-UX supported the HP Integral PC and HP 9000 Series 200, 300, and 400 computer systems based on the Motorola 68000 series of processors, the HP 9000 Series 500 computers based on HP's proprietary HP FOCUS, FOCUS architecture, and later HP 9000 Series models based on HP's PA-RISC instruction set architecture. HP-UX was the first Unix to offer access-control lists for file access permissions as an alternative to the standard Unix permissions system. HP-UX was also among the first Unix systems to include a built-in logical volume management, logical volume manager. HP has had a long partnership with Veritas Software, a ...

HPE Integrity Servers
HPE Integrity Servers is a series of server (computing), server computers produced by Hewlett Packard Enterprise (formerly Hewlett-Packard) since 2003, based on the Itanium processor. The Integrity brand name was inherited by HP from Tandem Computers via Compaq. In 2015, HP released the HP Superdome, Superdome X line of Integrity Servers based on the x86 Architecture. It is a 'small' Box holding up to 8 dual Socket Blades and supporting up to 16 processors/240 cores (when populated with Intel Xeon E7-2890 or E7-2880 Processors). General Over the years, Integrity systems have supported Windows Server, HP-UX#HP-UX 11i operating environments, HP-UX 11i, OpenVMS, NonStop (server computers), NonStop, Red Hat Enterprise Linux and SUSE Linux Enterprise Server operating systems on Integrity servers. As of 2020, the operating systems that are supported are HP-UX 11i, OpenVMS and NonStop. Early Integrity servers were based on two closely related chipsets. The zx1 chipset supported up to ...

Unix System V
Unix System V (pronounced: "System Five") is one of the first commercial versions of the Unix operating system. It was originally developed by AT&T and first released in 1983. Four major versions of System V were released, numbered 1, 2, 3, and 4. System V Release 4 (SVR4) was commercially the most successful version, being the result of an effort, marketed as ''Unix System Unification'', which solicited the collaboration of the major Unix vendors. It was the source of several common commercial Unix features. System V is sometimes abbreviated to SysV. , the AT&T-derived Unix market is divided between four System V variants: IBM's AIX, Hewlett Packard Enterprise's HP-UX and Oracle's Solaris, plus the free-software illumos forked from OpenSolaris. Overview Introduction System V was the successor to 1982's UNIX System III. While AT&T developed and sold hardware that ran System V, most customers ran a version from a reseller, based on AT&T's reference implementation. A ...

Itanium
Itanium (; ) is a discontinued family of 64-bit computing, 64-bit Intel microprocessors that implement the Intel Itanium architecture (formerly called IA-64). The Itanium architecture originated at Hewlett-Packard (HP), and was later jointly developed by HP and Intel. Launching in June 2001, Intel initially marketed the processors for enterprise servers and high-performance computing systems. In the concept phase, engineers said "we could run circles around PowerPC...we could kill the x86". Early predictions were that IA-64 would expand to the lower-end servers, supplanting Xeon, and eventually penetrate into the personal computers, eventually to supplant Reduced instruction set computer, reduced instruction set computing (RISC) and complex instruction set computing (CISC) architectures for all general-purpose applications. When first released in 2001 after a decade of development, Itanium's performance was disappointing compared to better-established RISC and CISC processors. Em ...

Unix
Unix (, ; trademarked as UNIX) is a family of multitasking, multi-user computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties in the late 1970s, leading to a variety of both academic and commercial Unix variants from vendors including University of California, Berkeley ( BSD), Microsoft (Xenix), Sun Microsystems ( SunOS/ Solaris), HP/ HPE ( HP-UX), and IBM ( AIX). The early versions of Unix—which are retrospectively referred to as " Research Unix"—ran on computers such as the PDP-11 and VAX; Unix was commonly used on minicomputers and mainframes from the 1970s onwards. It distinguished itself from its predecessors as the first portable operating system: almost the entire operating system is written in the C programming language (in 1973), which allows U ...

Software Distributor
Software Distributor (SD) is the Hewlett-Packard company's name for their HP-UX software package management system. SD provides a set of tools for creating packages that will install software on a system running the HP-UX operating system. The packages can be grouped together into a software repository called a depot, and a server can be configured to host multiple depots for installation of software packages and even entire systems. SD was first available with release 10.0 of HP-UX in 1995. Since then it has undergone several enhancements and bug fixes, and now provides a reliable software installation tool. It uses a client-server arrangement to distribute software using a background daemon called '. A software distributor provides its customers with the ability to purchase software licenses from multiple sources. This agent is started at boot time, and communicates using either the TCP or UDP protocols through RPC. The SD packages are normally stored and transmitted in compres ...

Common Desktop Environment
The Common Desktop Environment (CDE) is a desktop environment for Unix and OpenVMS, based on the Motif (software), Motif widget toolkit. It was part of the UNIX 98, UNIX 98 Workstation Product Standard, and was for a long time the Unix desktop associated with commercial Unix workstations. It helped to influence early implementations of successor projects such as KDE and GNOME, which largely replaced CDE following the turn of the century. After a long history as proprietary software, CDE was released as free software on August 6, 2012, under the GNU Lesser General Public License, version 2.0 or later. Since its release as free software, CDE has been ported to Linux and BSD derivatives. History Hewlett-Packard, IBM, SunSoft, Inc., SunSoft, and Unix System Laboratories, USL announced CDE in June 1993 as a joint development within the Common Open Software Environment (COSE) initiative. Each development group contributed its own technology to CDE: * HP contributed the primary envi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Single UNIX Specification
The Single UNIX Specification (SUS) is a standard for computer operating systems, compliance with which is required to qualify for using the "UNIX" trademark. The standard specifies programming interfaces for the C language, a command-line shell, and user commands. The core specifications of the SUS known as ''Base Specifications'' are developed and maintained by the Austin Group, which is a joint working group of IEEE, ISO/IEC JTC 1/SC 22/WG 15 and The Open Group. If an operating system is submitted to The Open Group for certification and passes conformance tests, then it is deemed to be compliant with a UNIX standard such as UNIX 98 or UNIX 03. Very few BSD and Linux-based operating systems are submitted for compliance with the Single UNIX Specification, although system developers generally aim for compliance with POSIX standards, which form the core of the Single UNIX Specification. The latest SUS consists of two parts: the ''base specifications'' technically iden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IA-64
IA-64 (Intel Itanium architecture) is the instruction set architecture (ISA) of the discontinued Itanium family of 64-bit Intel microprocessors. The basic ISA specification originated at Hewlett-Packard (HP), and was subsequently implemented by Intel in collaboration with HP. The first Itanium processor, codenamed ''Merced'', was released in 2001. The Itanium architecture is based on explicit instruction-level parallelism, in which the compiler decides which instructions to execute in parallel. This contrasts with superscalar architectures, which depend on the processor to manage instruction dependencies at runtime. In all Itanium models, up to and including '' Tukwila'', cores execute up to six instructions per cycle. In 2008, Itanium was the fourth-most deployed microprocessor architecture for enterprise-class systems, behind x86-64, Power ISA, and SPARC. In 2019, Intel announced the discontinuation of the last of the CPUs supporting the IA-64 architecture. Microsoft Win ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HP Integral PC
The HP Integral PC (or HP 9807A) is a portable UNIX workstation computer system produced by Hewlett-Packard, launched in 1985 at a price of £5450. It utilizes the Motorola 68000 microprocessor (running at 8 MHz) and ran the HP-UX 1.0 operating system. Hardware The Integral PC is a mains-powered portable computer with a 9-inch amber electroluminescent display with a resolution of 512×255 pixels or 80×25 characters (the 256th line of the display is not used). It also incorporated a 710 kB 3.5" floppy disk drive and an HP ThinkJet ink-jet printer. Standard memory capacity was 256 KB ROM plus 512 KB RAM, expandable to 7.5 MB. Expansion slots and an HP-IB bus were also included. The mechanical design was based on the ideas of the de facto standard HP-85. Within the Integral PC CPU, RAM, ROM, memory management, I/O buffering, system timing and keyboard interface are integrated on a single logic-board. All peripheral units and the 14 connections are built ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loadable Kernel Module
A loadable kernel module (LKM) is an executable library that extends the capabilities of a running kernel, or so-called ''base kernel'', of an operating system. LKMs are typically used to add support for new hardware (as device drivers) and/or filesystems, or for adding system calls. When the functionality provided by an LKM is no longer required, it can be unloaded in order to free memory and other resources. Most current Unix-like systems and Windows support loadable kernel modules but with different names, such as kernel loadable module (kld) in FreeBSD, kernel extension (kext) in macOS (although support for third-party modules is being dropped), kernel extension module in AIX, dynamically loadable kernel module in HP-UX, kernel-mode driver in Windows NT and downloadable kernel module (DKM) in VxWorks. They are also known as kernel loadable module (KLM), or simply as kernel module (KMOD). Advantages Without loadable kernel modules, an operating system would have to inc ...
