Altix
Altix is a line of server computers and supercomputers produced by Silicon Graphics (and successor company Silicon Graphics International), based on Intel processors. It succeeded the MIPS/IRIX-based Origin 3000 servers. History The line was first announced on January 7, 2003, with the Altix 3000 series, based on Intel Itanium 2 processors and SGI's NUMAlink processor interconnect. At product introduction, the system supported up to 64 processors running Linux as a single system image and shipped with a Linux distribution called SGI Advanced Linux Environment, which was compatible with Red Hat Advanced Server. By August 2003, many SGI Altix customers were running Linux on 128- and 256-processor SGI Altix systems. SGI officially announced 256-processor support within a single system image of Linux on March 10, 2004, using a 2.4-based Linux kernel. The SGI Advanced Linux Environment was eventually dropped after support using a standard, unmodified SUSE Linux Enterprise Server ...

Silicon Graphics
Silicon Graphics, Inc. (stylized as SiliconGraphics before 1999, later rebranded SGI, historically known as Silicon Graphics Computer Systems or SGCS) was an American high-performance computing manufacturer, producing computer hardware and software. Founded in Mountain View, California, in November 1981 by James H. Clark, the computer scientist and entrepreneur perhaps best known for founding Netscape (with Marc Andreessen). Its initial market was 3D graphics computer workstations, but its products, strategies and market positions developed significantly over time. Early systems were based on the RealityEngine, Geometry Engine that Clark and Marc Hannah had developed at Stanford University, and were derived from Clark's broader background in computer graphics. The Geometry Engine was the first very-large-scale integration (VLSI) implementation of a geometry pipeline, specialized hardware that accelerated the "inner-loop" geometric computations needed to display three-dimensional ...

NUMAlink
NUMAlink is a system interconnect developed by Silicon Graphics (SGI) for use in its distributed shared memory ccNUMA computer systems. NUMAlink was originally developed by SGI for their Origin 2000 and Onyx2 systems. At the time of these systems' introduction, it was branded as "CrayLink" during SGI's brief ownership of Cray Research. Hewlett Packard Enterprise entered an original equipment manufacturer (OEM) arrangement with Silicon Graphics International (SGI) to use Numalink as the foundation in some mission critical servers. ; Notes NUMAlink 2 There was no NUMAlink 1, as SGI's engineers deemed the system interconnect used in the Stanford DASH to be the first generation NUMAlink interconnect. NUMAlink 2 (branded as CrayLink) was announced in October 1996 for the Onyx2 visualization systems, the Origin 200 and the Origin 2000 servers and supercomputers. The NUMAlink 2 interface is the Hub ASIC. NUMAlink 2 is capable of 1.6 GB/s of peak bandwidth through two 800 MB ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Itanium 2
Itanium (; ) is a discontinued family of 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 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. Emulation to run existing x86 applications and operati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IRIX
IRIX (, ) is a discontinued operating system developed by Silicon Graphics (SGI) to run on the company's proprietary MIPS architecture, MIPS workstations and servers. It is based on UNIX System V with Berkeley Software Distribution, BSD extensions. In IRIX, SGI originated the XFS file system and the industry-standard OpenGL graphics API. History SGI originated the IRIX name in the 1988 release 3.0 of the operating system for the SGI IRIS 4D series of workstations and servers. Previous releases are identified only by the release number prefixed by "4D1-", such as "4D1-2.2". The "4D1-" prefix continued to be used in official documentation to prefix IRIX release numbers. Prior to the IRIS 4D, SGI bundled the GL2 operating system, based on UniSoft UniPlus System V Unix, and using the proprietary MEX (windowing system), MEX (Multiple EXposure) windowing system.

Multiprocessing
Multiprocessing (MP) is the use of two or more central processing units (CPUs) within a single computer system. The term also refers to the ability of a system to support more than one processor or the ability to allocate tasks between them. There are many variations on this basic theme, and the definition of multiprocessing can vary with context, mostly as a function of how CPUs are defined ( multiple cores on one die, multiple dies in one package, multiple packages in one system unit, etc.). A multiprocessor is a computer system having two or more processing units (multiple processors) each sharing main memory and peripherals, in order to simultaneously process programs. A 2009 textbook defined multiprocessor system similarly, but noted that the processors may share "some or all of the system’s memory and I/O facilities"; it also gave tightly coupled system as a synonymous term. At the operating system level, ''multiprocessing'' is sometimes used to refer to the executi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Press Release
A press release (also known as a media release) is an official statement delivered to members of the news media for the purpose of providing new information, creating an official statement, or making an announcement directed for public release. Press releases are also considered a primary source, meaning they are original informants for information. A press release is traditionally composed of nine structural elements, including a headline, dateline, introduction, body, and other components. Press releases are typically delivered to news media electronically, ready to use, and sometimes subject to "do not use before" time, known as a news embargo. A special example of a press release is a communiqué (; ), which is a brief report or statement released by a public agency. A communiqué is typically issued after a high-level meeting of international leaders. Using press releases can benefit media corporations because they can contribute to reducing costs and improve the amoun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Distributed Shared Memory
In computer science, distributed shared memory (DSM) is a form of memory architecture where physically separated memories can be addressed as a single shared address space. The term "shared" does not mean that there is a single centralized memory, but that the address space is shared—i.e., the same physical address on two Processor (computing), processors refers to the same location in memory. Distributed global address space (DGAS), is a similar term for a wide class of software and hardware implementations, in which each node (networking), node of a computer cluster, cluster has access to shared memory architecture, shared memory in addition to each node's private (i.e., not shared) Random-access memory, memory. Overview DSM can be achieved via software as well as hardware. Hardware examples include cache coherence circuits and network interface controllers. There are three ways of implementing DSM: * Page (computer memory), Page-based approach using virtual memory * Sha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silicon Graphics, Inc
Silicon is a chemical element; it has Symbol (chemistry), symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic lustre, and is a Tetravalence, tetravalent metalloid (sometimes considered a non-metal) and semiconductor. It is a member of carbon group, group 14 in the periodic table: carbon is above it; and germanium, tin, lead, and flerovium are below it. It is relatively unreactive. Silicon is a significant element that is essential for several physiological and metabolic processes in plants. Silicon is widely regarded as the predominant semiconductor material due to its versatile applications in various electrical devices such as transistors, solar cells, integrated circuits, and others. These may be due to its significant band gap, expansive optical transmission range, extensive absorption spectrum, surface roughening, and effective anti-reflection coating. Because of its high chemical affinity for oxygen, it was not until 1823 that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
