IWarp
iWarp was an experimental parallel supercomputer architecture developed as a joint project by Intel and Carnegie Mellon University. The project started in 1988, as a follow-up to CMU's previous WARP research project, in order to explore building an entire parallel-computing "node" in a single microprocessor, complete with memory and communications links. In this respect the iWarp is very similar to the INMOS transputer and nCUBE. Intel announced iWarp in 1989. The first iWarp prototype was delivered to Carnegie Mellon in summer of 1990, and in fall they received the first 64-cell production systems, followed by two more in 1991. With the creation of the Intel Supercomputing Systems Division in the summer of 1992, the iWarp was merged into the iPSC product line. Intel kept iWarp as a product but stopped actively marketing it. Each iWarp CPU included a 32-bit ALU with a 64-bit FPU running at 20 MHz. It was purely scalar and completed one instruction per cycle, so the per ...

WARP (systolic Array)
The ''Warp'' machines were 3 generations of increasingly general-purpose systolic array processors. Each generation became increasingly general-purpose by increasing memory capacity and loosening the coupling between processors. Only the original WW-Warp forced a truly lock step sequencing of stages, which severely restricted its programmability but was in a sense the purest “systolic-array” design. History The Warp machines were created by Carnegie Mellon University (CMU), in conjunction with industrial partners G.E., Honeywell and Intel, and funded by the U.S. Defense Advanced Research Projects Agency (DARPA). The ''Warp'' projects were started in 1984 by H. T. Kung at Carnegie Mellon University. The Warp projects yielded research results, publications and advancements in general purpose systolic hardware design, compiler design and systolic software algorithms. A two cell prototype of WW-Warp was complete at Carnegie Mellon in June 1985. Two essentially identical ten ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Systolic Array
In parallel computer architectures, a systolic array is a homogeneous network of tightly coupled data processing units (DPUs) called cells or nodes. Each node or DPU independently computes a partial result as a function of the data received from its upstream neighbours, stores the result within itself and passes it downstream. Systolic arrays were first used in Colossus, which was an early computer used to break German Lorenz ciphers during World War II. Due to the classified nature of Colossus, they were independently invented or rediscovered by H. T. Kung and Charles Leiserson who described arrays for many dense linear algebra computations (matrix product, solving systems of linear equations, LU decomposition, etc.) for banded matrices. Early applications include computing greatest common divisors of integers and polynomials. They are sometimes classified as multiple-instruction single-data (MISD) architectures under Flynn's taxonomy, but this classification is questionable ...

HCR Corporation
Human Computing Resources Corporation, later HCR Corporation, was a Canadian software company that worked on the Unix operating system and system software and business applications for it. Founded in 1976, it was based in Toronto. By a description of one of its founders, HCR was a "UNIX contract R&D and technology development and marketing firm." The company was most known for its extensive knowledge of Unix, for porting Unix to new hardware platforms, for developing compilers as part of the porting work, and for consulting and product development work on Unix. It was a pioneer in the Unix industry and by one account was the second firm ever to commercially support Unix. By 1990 HCR was a prominent player in the Canadian Unix scene. HCR was acquired by the Santa Cruz Operation (SCO) in 1990. It became the subsidiary SCO Canada, Inc., which existed until 1996 when the Toronto offices were closed. Origins at the University of Toronto Human Computing Resources was founded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
INMOS Transputer
The transputer is a series of pioneering microprocessors from the 1980s, intended for parallel computing. To support this, each transputer had its own integrated memory and serial communication links to exchange data with other transputers. They were designed and produced by Inmos, a semiconductor company based in Bristol, United Kingdom. For some time in the late 1980s, many considered the transputer to be the next great design for the future of computing. While the transputer did not achieve this expectation, the transputer architecture was highly influential in provoking new ideas in computer architecture, several of which have re-emerged in different forms in modern systems. Background In the early 1980s, conventional central processing units (CPUs) appeared to have reached a performance limit. Up to that time, manufacturing difficulties limited the amount of circuitry that could fit on a chip. Continued improvements in the fabrication process had largely removed th ...

Parallel Computing
Parallel computing is a type of computing, computation in which many calculations or Process (computing), processes are carried out simultaneously. Large problems can often be divided into smaller ones, which can then be solved at the same time. There are several different forms of parallel computing: Bit-level parallelism, bit-level, Instruction-level parallelism, instruction-level, Data parallelism, data, and task parallelism. Parallelism has long been employed in high-performance computing, but has gained broader interest due to the physical constraints preventing frequency scaling.S.V. Adve ''et al.'' (November 2008)"Parallel Computing Research at Illinois: The UPCRC Agenda" (PDF). Parallel@Illinois, University of Illinois at Urbana-Champaign. "The main techniques for these performance benefits—increased clock frequency and smarter but increasingly complex architectures—are now hitting the so-called power wall. The computer industry has accepted that future performance inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gigaflops
Floating point operations per second (FLOPS, flops or flop/s) is a measure of computer performance in computing, 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 computers use base two (with rare exceptions), 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 we ...
