Supercomputing In China
China operates a number of supercomputer centers which, altogether, hold 29.3% performance share of world's fastest 500 supercomputers. China's Sunway TaihuLight ranks third in the TOP500 list. In the November 2019 list, China dominated the globe's highest performance machines list with 228 out of the top 500 fastest supercomputers in the world, exceeding the second placing (United States) which had 117. History The origins of these centers go back to 1980s, when the State Planning Commission, the State Science and Technology Commission and the World Bank jointly launched a project to develop networking and supercomputer facilities in China. In addition to network facilities, the project included three supercomputer centers. The progress of supercomputing in China has been rapid; the country's most powerful supercomputer placed 43rd in November 2002 (DeepComp 1800), 11th by November 2003 (DeepComp 6800), 10th by June 2004 (Dawning 4000A), and by November 2010 (Tianhe-1A) h ...

MIPS Architecture
MIPS (Microprocessor without Interlocked Pipelined Stages) is a family of reduced instruction set computer (RISC) instruction set architectures (ISA)Price, Charles (September 1995). ''MIPS IV Instruction Set'' (Revision 3.2), MIPS Technologies, Inc. developed by MIPS Computer Systems, now MIPS Technologies, based in the United States. There are multiple versions of MIPS: including MIPS I, II, III, IV, and V; as well as five releases of MIPS32/64 (for 32- and 64-bit implementations, respectively). The early MIPS architectures were 32-bit; 64-bit versions were developed later. As of April 2017, the current version of MIPS is MIPS32/64 Release 6. MIPS32/64 primarily differs from MIPS I–V by defining the privileged kernel mode System Control Coprocessor in addition to the user mode architecture. The MIPS architecture has several optional extensions. MIPS-3D which is a simple set of floating-point SIMD instructions dedicated to common 3D tasks, MDMX (MaDMaX) which is a more exten ...

Personal Supercomputer
A personal supercomputer (PSC) is a marketing ploy used by computer manufacturers for high-performance computer systems and was a popular term in the mid 2000s to early 2010s. There is no exact definition for what a personal supercomputer is. Many systems have had that label put on them like the Cray CX1 and the Apple Power Mac G4. Generally, though the label is used on computers that are High end Workstations and Servers and have multiple processors and is small enough to fit on a desk or to the side. Other terms like PSC are Desktop/deskside supercomputers and supercomputers in a box. Deskside clusters This is the closest thing to a formal definition of a personal supercomputer as most Computers marketed as personal supercomputers are Deskside clusters like the Cray CX1. A Deskside cluster is as defined binsideHPC.com“Deskside clusters come in a chassis that you can plug into the wall of your office, and they are designed to sit on the floor next to your desk. The chassis ca ...

Microcomputer
A microcomputer is a small, relatively inexpensive computer having a central processing unit (CPU) made out of a microprocessor. The computer also includes memory and input/output (I/O) circuitry together mounted on a printed circuit board (PCB). Microcomputers became popular in the 1970s and 1980s with the advent of increasingly powerful microprocessors. The predecessors to these computers, mainframes and minicomputers, were comparatively much larger and more expensive (though indeed present-day mainframes such as the IBM System z machines use one or more custom microprocessors as their CPUs). Many microcomputers (when equipped with a keyboard and screen for input and output) are also personal computers (in the generic sense). An early use of the term ''personal computer'' in 1962 predates microprocessor-based designs. ''(See "Personal Computer: Computers at Companies" reference below)''. A ''microcomputer'' used as an embedded control system may have no human-readable input ...

Petaflops
In computing, floating point operations per second (FLOPS, flops or flop/s) is a measure of computer performance, useful in fields of scientific computations that require floating-point calculations. For such cases, it is a more accurate measure than measuring instructions per second. Floating-point arithmetic Floating-point arithmetic is needed for very large or very small real numbers, or computations that require a large dynamic range. Floating-point representation is similar to scientific notation, except everything is carried out in base two, rather than base ten. The encoding scheme stores the sign, the exponent (in base two for Cray and VAX, base two or ten for IEEE floating point formats, and base 16 for IBM Floating Point Architecture) and the significand (number after the radix point). While several similar formats are in use, the most common is ANSI/IEEE Std. 754-1985. This standard defines the format for 32-bit numbers called ''single precision'', as well as 64-b ...

National Supercomputing Center (Tianjin)
The National Supercomputing Center of Tianjin () is located at the National Defense Science and Technology University in Tianjin, China. One of the fastest supercomputers in the world (see "The TOP500 Project" list of supercomputers), Tianhe-1A, is located at the facility. History The Tianjin Computer Institute had been active as far back as 1984 and had developed the 16-bit TQ-0671 microcomputer system. As the National Supercomputing Center, the facilities came under the direction (purview) of the National Supercomputing Center council, consisting of members of the National Defense Science and Technology University, the various departments of the Tianjin Economic and Technological Development Zone, and the Tianjin Binhai New Area Administrative Committee. The facilities have been used by various people through the Beijing and Tianjin area. The center was built with the purpose of encouraging and initiating technological development and scientific innovation in the Tianjin Binhai N ...
