NEC SX-8
The SX-8 is a supercomputer built by NEC Corporation. The SX-8 Series implements an eight-way SMP system in a compact node module and uses an enhanced version of the single chip vector processor that was introduced with the SX-6. The NEC SX-8 processors run at 2 GHz for vectors and 1 GHz for scalar operations. The SX-8 CPU operates at 16 GFLOPS and can address up to 128 GB of memory. Up to 8 CPUs may be used in a single node, and a complete system may have up to 512 nodes. The SX-8 series ranges from the single-CPU SX-8b system to the SX-8/4096M512, with 512 nodes, 4,096 CPUs, and a peak performance of 65 TFLOPS. There is up to 512 GB/s bandwidth per node (64 GB/s per processor). The SX-8 runs SUPER-UX, a Unix-like operating system developed by NEC. The first production SX-8 was installed at the UK Met Office in early 2005. In October 2006, an upgraded SX-8 was announced, the SX-8R. The NEC SX-8R processors run at 2.2 GHz for vectors and 1.1 GHz for scal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NEC SX-8 Frame (1)
is a Japanese multinational information technology and electronics corporation, headquartered in Minato, Tokyo. The company was known as the Nippon Electric Company, Limited, before rebranding in 1983 as NEC. It provides IT and network solutions, including cloud computing, artificial intelligence (AI), Internet of things (IoT) platform, and telecommunications equipment and software to business enterprises, communications services providers and to government agencies, and has also been the biggest PC vendor in Japan since the 1980s when it launched the PC-8000 series. NEC was the world's fourth-largest PC manufacturer by 1990. Its semiconductors business unit was the world's largest semiconductor company by annual revenue from 1985 to 1992, the second largest in 1995, one of the top three in 2000, and one of the top 10 in 2006. NEC spun off its semiconductor business to Renesas Electronics and Elpida Memory. Once Japan's major electronics company, NEC has largely with ...

Symmetric Multiprocessing
Symmetric multiprocessing or shared-memory multiprocessing (SMP) involves a multiprocessor computer hardware and software architecture where two or more identical processors are connected to a single, shared main memory, have full access to all input and output devices, and are controlled by a single operating system instance that treats all processors equally, reserving none for special purposes. Most multiprocessor systems today use an SMP architecture. In the case of multi-core processors, the SMP architecture applies to the cores, treating them as separate processors. Professor John D. Kubiatowicz considers traditionally SMP systems to contain processors without caches. Culler and Pal-Singh in their 1998 book "Parallel Computer Architecture: A Hardware/Software Approach" mention: "The term SMP is widely used but causes a bit of confusion. ..The more precise description of what is intended by SMP is a shared memory multiprocessor where the cost of accessing a memory locatio ...

NEC SX-6
The SX-6 is a NEC SX supercomputer built by NEC Corporation that debuted in 2001; the SX-6 was sold under license by Cray Inc. in the U.S. Each SX-6 single-node system contains up to eight vector processors, which share up to 64 GB of computer memory. The SX-6 processor is a single chip implementation containing a vector processor unit and a scalar processor fabricated in a 0.15 μm CMOS process with copper interconnects, whereas the SX-5 was a multi-chip implementation. The Earth Simulator is based on the SX-6 architecture. The vector processor is made up of eight vector pipeline units each with seventy-two 256-word vector registers. The vector unit performs add/shift, multiply, divide and logical operations. The scalar unit is 64 bits wide and contains a 64 KB cache. The scalar unit can decode, issue and complete four instructions per clock cycle. Branch prediction and speculative execution is supported. A multi-node system is configured by interconnecting up to 128 single-node s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SUPER-UX
SUPER-UX is a version of the Unix operating system from NEC that is used on its SX series of supercomputers. History The initial version of SUPER-UX was based on UNIX System V version 3.1 with features from BSD 4.3. The version for the NEC SX-9 was based on SVR4.2MP with BSD enhancements. Features SUPER-UX is a 64-bit UNIX operating system. It supports the Supercomputer File System (SFS). Earth Simulator The Earth Simulator The is a series of supercomputers deployed at Japan Agency for Marine-Earth Science and Technology Yokohama Institute of Earth Sciences. Earth Simulator (first generation) The first generation of Earth Simulator, developed by the Japanese g ... uses a custom OS called "ESOS" (Earth Simulator Operating System) based on SUPER-UX. It has many enhanced features custom designed for the Earth Simulator which are not in the regular SUPER-UX OS.

Unix-like
A Unix-like (sometimes referred to as UN*X or *nix) operating system is one that behaves in a manner similar to a Unix system, although not necessarily conforming to or being certified to any version of the Single UNIX Specification. A Unix-like application is one that behaves like the corresponding Unix command or shell. Although there are general philosophies for Unix design, there is no technical standard defining the term, and opinions can differ about the degree to which a particular operating system or application is Unix-like. Some well-known examples of Unix-like operating systems include Linux and BSD. These systems are often used on servers, as well as on personal computers and other devices. Many popular applications, such as the Apache web server and the Bash shell, are also designed to be used on Unix-like systems. One of the key features of Unix-like systems is their ability to support multiple users and processes simultaneously. This allows users to run mult ...

Met Office
The Meteorological Office, abbreviated as the Met Office, is the United Kingdom's national weather service. It is an executive agency and trading fund of the Department for Business, Energy and Industrial Strategy and is led by CEO Penelope Endersby, who took on the role as Chief Executive in December 2018 and is the first woman to do so. The Met Office makes meteorological predictions across all timescales from weather forecasts to climate change. History The Met Office was established on 1 August 1854 as a small department within the Board of Trade under Vice Admiral Robert FitzRoy as a service to mariners. The loss of the passenger vessel, the ''Royal Charter'', and 459 lives off the coast of Anglesey in a violent storm in October 1859 led to the first gale warning service. FitzRoy established a network of 15 coastal stations from which visual gale warnings could be provided for ships at sea. The new electric telegraph enabled rapid dissemination of warnings and ...
