Cray-1S
The Cray-1 was a supercomputer designed, manufactured and marketed by Cray Research. Announced in 1975, the first Cray-1 system was installed at Los Alamos National Laboratory in 1976. Eventually, eighty Cray-1s were sold, making it one of the most successful supercomputers in history. It is perhaps best known for its unique shape, a relatively small C-shaped cabinet with a ring of benches around the outside covering the power supplies and the cooling system. The Cray-1 was the first supercomputer to successfully implement the vector processor design. These systems improve the performance of math operations by arranging memory and registers to quickly perform a single operation on a large set of data. Previous systems like the CDC STAR-100 and ASC had implemented these concepts but did so in a way that seriously limited their performance. The Cray-1 addressed these problems and produced a machine that ran several times faster than any similar design. The Cray-1's architect was ...

Founding and history The museum was founded in 1857 under Bennet Woodcroft from the collection of the Royal Society of Arts and surplus items from the Great Exhibition as part of the South Kensington Museum, together with what is now the Victoria and Albert Museum. It included a collection of machinery which became the ''Museum of Patents'' in 1858, and the ''Patent Office Museum'' in 1863. This collection contained many of the most famous exhibits of what is now th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Design News
Design News is a business-to-business media brand covering news, trends, and technology insights for the engineering community. Owned by Informa Markets — Engineering, it is headquartered in Santa Monica, California. The brand has been in publication since 1946. History and ownership ''Design News'' began as a monthly print magazine, serving design, mechanical, and electrical engineers. As of December 2014, its print circulation was audited at 96,667 by the BPA. In 2010, Reed Business Information sold ''Design News''—along with other U.S. electronics titles—to Canon Communications. Canon was subsequently acquired by United Business Media (UBM). In 2018, Informa purchased UBM in a deal valued at $5.3 billion. Over time, ''Design News'' transitioned to an online-only publication, although it retains its original focus on engineering and manufacturing topics. Coverage ''Design News'' serves engineers in the aerospace, automotive, consumer electronics/appliance, gover ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Center For Atmospheric Research
The US National Center for Atmospheric Research (NCAR ) is a US federally funded research and development center (FFRDC) managed by the nonprofit University Corporation for Atmospheric Research (UCAR) and funded by the National Science Foundation (NSF). NCAR has multiple facilities, including the I. M. Pei-designed Mesa Laboratory headquarters in Boulder, Colorado.

Wall Street
Wall Street is a street in the Financial District, Manhattan, Financial District of Lower Manhattan in New York City. It runs eight city blocks between Broadway (Manhattan), Broadway in the west and South Street (Manhattan), South Street and the East River in the east with a length of just under 2,000 feet. The term "Wall Street" has become a Metonymy, metonym for the financial markets of the United States as a whole, the Financial services in the United States, American financial services industry, New York–based financial interests, or the Financial District. Anchored by Wall Street, New York has been described as the world's principal fintech and financial center. The street was originally known in Dutch language, Dutch as ''Het Cingel'' ("the Belt") when it was part of New Amsterdam during the 17th century. An actual city wall existed on the street from 1653 to 1699. During the 18th century, the location served as a slave market and Security (finance), securities ...

William Norris (CEO)
William Charles Norris (July 14, 1911, near Red Cloud, Nebraska – August 21, 2006) was an American business executive. He was the CEO of Control Data Corporation, at one time one of the most powerful and respected computer companies in the world. He is famous for taking on IBM in a head-on fight and winning, as well as being a social activist who used Control Data's expansion in the late 1960s to bring jobs and training to inner cities and disadvantaged communities. Early life Norris was born and raised on a cattle farm in Nebraska, attending a tiny school in Inavale, Nebraska, and operating a ham radio. He attained a degree in electrical engineering from the University of Nebraska in 1932. He spent two years on his family's farm after graduation, helping weather the Great Depression and a significant drought in the Midwest by risking the use of Russian thistle as cattle feed. Military career Norris served in the United States Navy as a codebreaker, attaining the rank ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SIMD
Single instruction, multiple data (SIMD) is a type of parallel computer, parallel processing in Flynn's taxonomy. SIMD describes computers with multiple processing elements that perform the same operation on multiple data points simultaneously. SIMD can be internal (part of the hardware design) and it can be directly accessible through an instruction set architecture (ISA), but it should not be confused with an ISA. Such machines exploit Data parallelism, data level parallelism, but not Concurrent computing, concurrency: there are simultaneous (parallel) computations, but each unit performs exactly the same instruction at any given moment (just with different data). A simple example is to add many pairs of numbers together, all of the SIMD units are performing an addition, but each one has different pairs of values to add. SIMD is particularly applicable to common tasks such as adjusting the contrast in a digital image or adjusting the volume of digital audio. Most modern Cen ...

Lockstep (computing)
Lockstep systems are fault-tolerant computer systems that run the same set of operations at the same time in parallel. The redundancy (duplication) allows error detection and error correction: the output from lockstep operations can be compared to determine if there has been a fault if there are at least two systems ( dual modular redundancy DMR), and the error can be automatically corrected if there are at least three systems ( triple modular redundancy TMR), via majority vote. The term " lockstep" originates from army usage, where it refers to synchronized walking, in which marchers walk as closely together as physically practical. To run in lockstep, each system is set up to progress from one well-defined state to the next well-defined state. When a new set of inputs reaches the system, it processes them, generates new outputs and updates its state. This set of changes (new inputs, new outputs, new state) is considered to define that step, and must be treated as an atomic t ...
