Supercomputer
Capturing complex visualizations, such as the above Dali-esque rendering of a supernova, don’t just produce pretty pictures ideal for desktop wallpapers. They also allow scientists to see simulations of complex physical, chemical and biological phenomena. Unfortunately generating the quadrillions of data points required for visualizations of everything from supernovas to protein structures is quickly overwhelming current computing capabilities. So scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory are exploring ways to speed up the process using a technique called software-based parallel volume rendering.

Today's computers can carry on a wide range of tasks thanks to a general architecture that allows for great flexibility at the cost of a non-optimal performance; on the other end, application-specific integrated circuits (ASICs) can carry on a very specific task with great speed and energy efficiency, but are very inflexible. Now Novo-G, a reconfigurable supercomputer developed at the University of Florida that's described as the most powerful of its kind, is attempting to take the best from both worlds by being able to effectively change its hardware configuration as needed to compute with the greatest possible speed and efficiency.

June 17, 2008 A collaboration between IBM and the Los Alamos National Laboratory has resulted in the world's fastest supercomputer. Roadrunner can run at speeds above the "petaflop barrier" of 1,000 trillion operations per second, making it twice as fast as IBM's Blue Gene/L™ and opening up an era of science at a previously unseen scale.

Pedal-powered supercomputer: MIT Cycling team sets new record
December 15, 2007 Cyclists from the Massachusetts Institute of Technology (MIT) have set a new world record in Human Powered Computation (HPC). The team of 10 used bicycles to power a SiCortex SC648 supercomputer drawing 1.2 kilowatts of electricity, riding non-stop for 20 minutes to achieve the feat of the largest HPC in history. Read More
June 20, 2007 The speed of collaborative research using Europe’s network of supercomputers will be advanced by a major upgrade announced today. The Distributed European Infrastructure for Supercomputing Applications (DEISA), has increased connectivity speeds ten-fold to 10 Gbps, through dedicated links designed and deployed by the GEANT2 pan-European research and education network.

January 16, 2007 The seemingly endless amount of money available in Formula One is directly related to its audience size and the influence it has. Success in Formula One, the world’s most watched sporting series, is the world’s most visible gauge of automotive technological prowess, and it is so sought after because it adds value to the company brand name. With BMW entering the fray under its own name last year, it isn’t about to settle for anything less than the top step of the podium and has embarked on its quest with the aid of one of the world’s most powerful computers. The BMW Sauber F1 Team new super brain, Albert2 is Europe's fastest computer currently used in industry. It’s roughly three times faster than its predecessor and is employed solely in the study of computational fluid dynamics (CFD). Rather than going with the current trend where many teams are building a second wind tunnel, BMW invested its racing budget in Albert2, which is quite a specimen. It’s main memory is 2,048 Gb – it 256 nodes with two Intel Xeon 5160 processors each, and each of these has two cores. This results in a total of 1024 cores and a maximum computing power is 12,288 GFlops. This means that Albert2 is capable of performing 12,288,000,000,000 floating-point arithmetic operations per second. Read More
