Finite Element Machine
The Finite Element Machine (FEM) was a late 1970s-early 1980s NASA project to build and evaluate the performance of a parallel computer for structural analysis. The FEM was completed and successfully tested at the NASA Langley Research Center in Hampton, Virginia. The motivation for FEM arose from the merger of two concepts: the finite element method of structural analysis and the introduction of relatively low-cost microprocessors. In the finite element method, the behavior (stresses, strains and displacements resulting from load conditions) of large-scale structures is approximated by a FE model consisting of structural elements (members) connected at structural node points. Calculations on traditional computers are performed at each node point and results communicated to adjacent node points until the behavior of the entire structure is computed. On the Finite Element Machine, microprocessors located at each node point perform these nodal computations in parallel. If there ...

USEC
Centrus Energy Corp. (formerly USEC Inc.) is an American company that supplies nuclear fuel for use in nuclear power plants and works to develop and deploy advanced centrifuge technology to produce enriched uranium for commercial and government uses, including for national security. In 2019, Centrus began work under a contract with the U.S. Department of Energy to build a cascade of 16 centrifuges in Piketon, Ohio to demonstrate production of High-Assay, Low-Enriched Uranium, or HALEU. HALEU is required for many next generation reactor designs, including nine of the ten reactor designs selected under the Energy Department’s Advanced Reactor Demonstration Program. In June 2021, the U.S. Nuclear Regulatory Commission approved a license amendment request for Centrus to enrich uranium up to a Uranium-235 concentration of 20 percent, making it the first U.S. facility licensed for HALEU production. This is higher than the 5 percent level found in Low-Enriched Uranium that is used i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Supercomputers
A supercomputer is a computer with a high level of performance as compared to a general-purpose computer. The performance of a supercomputer is commonly measured in floating-point operations per second (FLOPS) instead of million instructions per second (MIPS). Since 2017, there have existed supercomputers which can perform over 1017 FLOPS (a hundred quadrillion FLOPS, 100 petaFLOPS or 100 PFLOPS). For comparison, a desktop computer has performance in the range of hundreds of gigaFLOPS (1011) to tens of teraFLOPS (1013). Since November 2017, all of the world's fastest 500 supercomputers run on Linux-based operating systems. Additional research is being conducted in the United States, the European Union, Taiwan, Japan, and China to build faster, more powerful and technologically superior exascale supercomputers. Supercomputers play an important role in the field of computational science, and are used for a wide range of computationally intensive tasks in variou ...

Parallel Computing
Parallel computing is a type of computation in which many calculations or 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, instruction-level, 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 increases must largely come from increasing the number of processors (or cores) on a die, rather than m ...

NASA Online
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management for ...

History Of Hampton, Virginia
Hampton () is an independent city in the Commonwealth of Virginia in the United States. As of the 2020 census, the population was 137,148. It is the 7th most populous city in Virginia and 204th most populous city in the nation. Hampton is included in the Hampton Roads Metropolitan Statistical Area (officially known as the Virginia Beach–Norfolk–Newport News, VA–NC MSA) which is the 37th largest in the United States, with a total population of 1,799,674 (2020). This area, known as "America's First Region", also includes the independent cities of Chesapeake, Virginia Beach, Newport News, Norfolk, Portsmouth, and Suffolk, as well as other smaller cities, counties, and towns of Hampton Roads. Hampton traces its history to the city's Old Point Comfort, the home of Fort Monroe for almost 400 years, which was named by the 1607 voyagers, led by Captain Christopher Newport, who first established Jamestown as an English colonial settlement. Since consolidation in 1952, Hamp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minisupercomputer
Minisupercomputers constituted a short-lived class of computers that emerged in the mid-1980s, characterized by the combination of vector processing and small-scale multiprocessing. As scientific computing using vector processors became more popular, the need for lower-cost systems that might be used at the departmental level instead of the corporate level created an opportunity for new computer vendors to enter the market. As a generalization, the price targets for these smaller computers were one-tenth of the larger supercomputers. Several notable technical, economic, and political attributes characterize minisupercomputers. First, they were architecturally more diverse than prior mainframes and minicomputers in hardware and less diverse in software. Second, advances in VLSI made them less expensive (mini-price). These machines were market targeted to be cost-effective and quickly manufactured. Third, it is notable who did not manufacture minisupercomputers: within the USA, IBM ...

AlphaStar Corporation
''For the AI software: AlphaStar (software)'' AlphaStar Digital Television was a direct-to-home satellite broadcasting service for the United States market developed by Canadian firm Tee-Comm Electronics. It was the first direct-to-home satellite broadcasting service in the United States to use the internationally accepted DVB-S broadcasting standard and used 39" satellite dish receivers. Its service launched in July 1996, but was discontinued completely by September 1997 with 40,000 subscribers as the company went through bankruptcy proceedings. The American assets of AlphaStar was used under the auspices of the Champion Telecom Platform which used to own the AlphaStar brand. AlphaStar would also have alleviated a shortage of Canadian satellite capacity by using foreign (US) satellite capacity to fill Canadian needs—indeed this was a requirement for the Canadian company to obtain its license from Canada to commence broadcasting. Tee-Comm, the parent company of AlphaStar had ori ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Algorithm
In mathematics and computer science, an algorithm () is a finite sequence of rigorous instructions, typically used to solve a class of specific Computational problem, problems or to perform a computation. Algorithms are used as specifications for performing calculations and data processing. More advanced algorithms can perform automated deductions (referred to as automated reasoning) and use mathematical and logical tests to divert the code execution through various routes (referred to as automated decision-making). Using human characteristics as descriptors of machines in metaphorical ways was already practiced by Alan Turing with terms such as "memory", "search" and "stimulus". In contrast, a Heuristic (computer science), heuristic is an approach to problem solving that may not be fully specified or may not guarantee correct or optimal results, especially in problem domains where there is no well-defined correct or optimal result. As an effective method, an algorithm ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intel Paragon
The Intel Paragon is a discontinued series of massively parallel supercomputers that was produced by Intel in the 1990s. The Paragon XP/S is a productized version of the experimental ''Touchstone Delta'' system that was built at Caltech, launched in 1992. The Paragon superseded Intel's earlier iPSC/860 system, to which it is closely related. The Paragon series is based on the Intel i860 RISC microprocessor. Up to 2048 (later, up to 4096) i860s are connected in a 2D grid. In 1993, an entry-level Paragon XP/E variant was announced with up to 32 compute nodes. The system architecture is a partitioned system, with the majority of the system comprising diskless compute nodes and a small number of I/O nodes interactive service nodes. Since the bulk of the nodes have no permanent storage, it is possible to "Red/Black switch" the compute partition from classified to unclassified by disconnecting one set of I/O nodes with classified disks and then connecting an unclassified I/O partitio ...
