(Phys.org) —What better place to use the "new vintage" computing theme than in Napa Valley where the Cray User Group meeting took place on Tuesday, The tie-in this year is Cray's new vintage of supercomputers for a business segment that Cray calls the "technical enterprise." In brief, Cray has seen an opportunity to accommodate the need for complex computing simulations of supercomputers but engineered (in the form of economized packaging, networking, cooling and power options) at a price that businesses can entertain. Cray used the Tuesday event to announce a lower-priced version of a Cray XC30 system, for business customers. The new supercomputer is the XC30-AC, shipping with Intel Xeon processors, which will sell as a low-cost model priced from $500,000 on up. http://phys.org/news287245203.html Electronics Wed, 08 May 2013 15:20:19 EST news287245203 A National Science Foundation-supported, world-class supercomputer called Stampede—which has already enabled research teams to predict where and when earthquakes may strike, how much sea levels could rise and how fast brain tumors grow—was officially dedicated today. http://phys.org/news283708769.html Technology Thu, 28 Mar 2013 16:59:40 EST news283708769 Mobile network operators are facing inevitable and hard reforms in their business. Although the consumption of mobile data increases rapidly, operators' user revenues have been sinking steadily for years. For now, operators are economically in good shape, but in their current state they run the risk of being left out of the mobile business ecosystem. http://phys.org/news277451597.html Technology Tue, 15 Jan 2013 05:53:33 EST news277451597 When most people hear the word "graph," an image springs to mind: a pair of perpendicular lines overlaid with a line, a curve, or bars of different heights. http://phys.org/news274951017.html Technology Mon, 17 Dec 2012 07:17:19 EST news274951017 The law created to protect children's online privacy actually increases risk, according to new research from Polytechnic Institute of New York University (NYU-Poly). http://phys.org/news273746095.html Technology Mon, 03 Dec 2012 08:37:17 EST news273746095 Quantum computers are devices—still largely theoretical—that could perform certain types of computations much faster than classical computers; one way they might do that is by exploiting "spin," a property of tiny particles of matter. A "spin chain," in turn, is a standard model that physicists use to describe systems of quantum particles, including some that could be the basis for quantum computers. http://phys.org/news273220290.html Physics Tue, 27 Nov 2012 06:31:50 EST news273220290 Researchers at Oak Ridge National Laboratory (ORNL) are sharing computational resources and expertise to improve the detail and performance of a scientific application code that is the product of one of the world's largest collaborations of climate researchers. The Community Earth System Model (CESM) is a mega-model that couples components of atmosphere, land, ocean, and ice to reflect their complex interactions. By continuing to improve science representations and numerical methods in simulations, and exploiting modern computer architectures, researchers expect to further improve the CESM's accuracy in predicting climate changes. Achieving that goal requires teamwork and coordination rarely seen outside a symphony orchestra. http://phys.org/news249650692.html Technology Tue, 28 Feb 2012 11:25:02 EST news249650692 Imagine trying to analyze all of the English entries in Wikipedia. Now imagine you've got 20 times as much information. That's the challenge scientists face when working with gigabyte data sets. Scientists at Pacific Northwest National Laboratory, Sandia National Laboratories and Cray, Inc. developed an application to take on such massive data analysis challenges. Their novel high-performance computing application uses semantic factoring to organize data, bringing out hidden connections and threads. http://phys.org/news235728814.html Technology Tue, 20 Sep 2011 09:30:01 EST news235728814 The San Diego Supercomputer Center at UC San Diego is part of a team chosen by the National Science Foundation to build and run an experimental high-performance grid test-bed, allowing researchers to collaboratively develop and test new approaches to parallel, grid and cloud computing. http://phys.org/news173453514.html Technology Tue, 29 Sep 2009 14:50:03 EST news173453514 A $30 million National Science Foundation grant will enable the University of Chicago to expand and extend until 2011 the operation of TeraGrid, a national system of interconnected supercomputers devoted to leading-edge scientific discovery and science and technology education. http://phys.org/news170945731.html Technology Mon, 31 Aug 2009 13:56:07 EST news170945731 (PhysOrg.com) -- "For certain tasks, quantum computers are more powerful than their classical counterparts. The task to be performed is the same for quantum or classical systems. However, the former ones can do it in a more efficient way," David Gross tells PhysOrg.com. "But we can’t pinpoint the exact reason why a quantum computer is more powerful. Until now, it has been accepted that the reason is entanglement. But entanglement is the easy answer, and we have discovered that it is not so simple." http://phys.org/news162468404.html Physics Mon, 25 May 2009 11:07:15 EST news162468404
