XCAT Racing
xCAT (Extreme Cloud Administration Toolkit) is open-source distributed computing management software developed by IBM, used for the deployment and administration of Linux or AIX based clusters. In September 2023 the primary developers of xCAT said that they moved onto other roles and could no longer work on it, asking the community if anyone would like to take over, as otherwise they planned to end-of-life the project on December 1, 2023. A consortium of companies organized to take over the development, later releasing version 2.17. Toolkit xCAT can: * Create and manage diskless clusters * Install and manage many Linux cluster machines (physical or virtual) in parallel * Set up a high-performance computing software stack, including software for batch job submission, parallel libraries, and other software that is useful on a cluster * Cloning and imaging Linux and Windows machines xCAT has specific features designed to take advantage of IBM hardware including: * Remote P ...

Diskless Node
A diskless node (or diskless workstation) is a workstation or personal computer without disk drives, which employs network booting to load its operating system from a server. (A computer may also be said to ''act as a diskless node'', if its disks are unused and network booting is used.) Diskless nodes (or computers acting as such) are sometimes known as '' network computers'' or hybrid clients. ''Hybrid client'' may either just mean diskless node, or it may be used in a more particular sense to mean a diskless node which runs ''some'', but not all, applications remotely, as in the thin client computing architecture. Advantages of diskless nodes can include lower production cost, lower running costs, quieter operation, and manageability advantages (for example, centrally managed software installation). In many universities and in some large organizations, PCs are used in a similar configuration, with some or all applications stored remotely but executed locally—again, f ...

Cluster Computing
A computer cluster is a set of computers that work together so that they can be viewed as a single system. Unlike Grid computing, grid computers, computer clusters have each Node (networking), node set to perform the same task, controlled and scheduled by software. The newest manifestation of cluster computing is cloud computing. The components of a cluster are usually connected to each other through fast local area networks, with each Node (networking), node (computer used as a server) running its own instance of an operating system. In most circumstances, all of the nodes use the same hardware and the same operating system, although in some setups (e.g. using Open Source Cluster Application Resources (OSCAR)), different operating systems can be used on each computer, or different hardware. Clusters are usually deployed to improve performance and availability over that of a single computer, while typically being much more cost-effective than single computers of comparable s ...

IBM System Cluster 1350
The IBM Intelligent Cluster was a cluster solution for x86-based high-performance computing composed primarily of IBM (IBM System x, System x, IBM BladeCenter, BladeCenter and IBM System Storage, System Storage) components, integrated with network switches from various vendors and optional high-performance InfiniBand interconnects. History The solution was formerly known as the IBM eServer Cluster 1300 (or e1300) based on then-current Pentium III processors, which was introduced in November 2001. This was replaced by the e1350 in October 2002 with the introduction of Pentium 4-based Intel Xeon processors. Later (in 2008-2009) solution also was known as the IBM System Cluster 1350; in 2010 released line with final IBM Intelligent Cluster name. Roughly twice a year the solution components were updated to include the then-current products from IBM and other vendors. In 2014 this cluster solution was sold and rebranded as Lenovo Intelligent Cluster. Architecture The Intelligent ...

Instructions Per Second
Instructions per second (IPS) is a measure of a computer's Central processing unit, processor speed. For complex instruction set computers (CISCs), different Machine code, instructions take different amounts of time, so the value measured depends on the instruction mix; even for comparing processors in the same family the IPS measurement can be problematic. Many reported IPS values have represented "peak" execution rates on artificial instruction sequences with few Subroutine, branches and no Resource contention, cache contention, whereas realistic workloads typically lead to significantly lower IPS values. Memory hierarchy also greatly affects processor performance, an issue barely considered in IPS calculations. Because of these problems, synthetic Benchmark (computing), benchmarks such as Dhrystone are now generally used to estimate computer performance in commonly used applications, and raw IPS has fallen into disuse. The term is commonly used in association with a metric pr ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

IBM Roadrunner
Roadrunner was a supercomputer built by IBM for the Los Alamos National Laboratory in New Mexico, USA. The US$100-million Roadrunner was designed for a peak performance of 1.7 petaflops. It achieved 1.026 petaflops on May 25, 2008, to become the world's first TOP500 LINPACK sustained 1.0 petaflops system. In November 2008, it reached a top performance of 1.456 petaFLOPS, retaining its top spot in the TOP500 list. It was also the fourth-most energy-efficient supercomputer in the world on the Supermicro Green500 list, with an operational rate of 444.94 megaflops per watt of power used. The hybrid Roadrunner design was then reused for several other energy efficient supercomputers. Roadrunner was decommissioned by Los Alamos on March 31, 2013. In its place, Los Alamos commissioned a supercomputer called Cielo, which was installed in 2010. Overview IBM built the computer for the U.S. Department of Energy's (DOE) National Nuclear Security Administration (NNSA). It was a hybrid ...

Email
Electronic mail (usually shortened to email; alternatively hyphenated e-mail) is a method of transmitting and receiving Digital media, digital messages using electronics, electronic devices over a computer network. It was conceived in the late–20th century as the digital version of, or counterpart to, mail (hence ''wikt:e-#Etymology 2, e- + mail''). Email is a ubiquitous and very widely used communication medium; in current use, an email address is often treated as a basic and necessary part of many processes in business, commerce, government, education, entertainment, and other spheres of daily life in most countries. Email operates across computer networks, primarily the Internet access, Internet, and also local area networks. Today's email systems are based on a store-and-forward model. Email Server (computing), servers accept, forward, deliver, and store messages. Neither the users nor their computers are required to be online simultaneously; they need to connect, ty ...

Simple Network Management Protocol
Simple Network Management Protocol (SNMP) is an Internet Standard protocol for collecting and organizing information about managed devices on IP networks and for modifying that information to change device behavior. Devices that typically support SNMP include cable modems, routers, network switches, servers, workstations, printers, and more. SNMP is widely used in network management for network monitoring. SNMP exposes management data in the form of variables on the managed systems organized in a management information base (MIB), which describes the system status and configuration. These variables can then be remotely queried (and, in some circumstances, manipulated) by managing applications. Three significant versions of SNMP have been developed and deployed. SNMPv1 is the original version of the protocol. More recent versions, SNMPv2c and SNMPv3, feature improvements in performance, flexibility and security. SNMP is a component of the Internet Protocol Suite as def ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

BIOS
In computing, BIOS (, ; Basic Input/Output System, also known as the System BIOS, ROM BIOS, BIOS ROM or PC BIOS) is a type of firmware used to provide runtime services for operating systems and programs and to perform hardware initialization during the booting process (power-on startup). The firmware comes pre-installed on the computer's motherboard. The name originates from the Basic Input/Output System used in the CP/M operating system in 1975. The BIOS firmware was originally proprietary to the IBM PC; it was reverse engineered by some companies (such as Phoenix Technologies) looking to create compatible systems. The interface of that original system serves as a ''de facto'' standard. The BIOS in older PCs initializes and tests the system hardware components ( power-on self-test or POST for short), and loads a boot loader from a mass storage device which then initializes a kernel. In the era of DOS, the BIOS provided BIOS interrupt calls for the keyboard, display, st ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Power-on Self-test
A power-on self-test (POST) is a process performed by firmware or software routines immediately after a computer or other digital electronic device is powered on. POST processes may set the initial state of the device from firmware and detect if any hardware components are non-functional. The results of the POST may be displayed on a panel that is part of the device, output to an external device, or stored for future retrieval by a diagnostic tool. In some computers, an indicator lamp or a PC speaker, speaker may be provided to show error codes as a sequence of flashes or Beep (sound), beeps in the event that a computer display malfunctions. POST routines are part of a computer's pre-boot sequence. If they complete successfully, the bootstrap loader code is invoked to load an operating system. In IBM PC compatible computers, the main duties of POST are handled by the BIOS or UEFI. IBM-compatible PC POST In IBM PC compatible computers, the main duties of POST are handled by ...
