Yale purchases world-class supercomputer

Yale researchers will be able to crunch larger amounts of data even faster, now that the University has acquired a new supercomputer - one rated #146 in the world by the TOP500.org, which tracks and rates supercomputer systems. It is also the top-rated supercomputer among the Ivies.

A Chinese scientific research centre has built the fastest supercomputer ever made, replacing the United States as maker of the swiftest machine, and giving China bragging rights as a technology superpower.
The computer, known as Tianhe-1A, has 1.4 times the horsepower of the current top computer, which is at a national laboratory in Tennessee, as measured by the standard test used to gauge how well the systems handle mathematical calculations, said Jack Dongarra, a University of Tennessee computer scientist who maintains the official supercomputer rankings.

The University of Chicago Computation Institute (UC-CI), and the National Institutes of Health (NIH) are pleased to announce the introduction of Beagle, a 150 teraflop Cray XE6 supercomputer that will support computation, simulation and data analysis for the biomedical research community. HPC consulting and user support for Beagle will be provided by the iBi. The system will be housed in the new Theory and Computing Sciences (TCS) building at Argonne National Laboratory (ANL) and will be available for use by UC researchers, their collaborators and other meritorious investigators nationwide.

A UK campaign to build a truck-sized, prototype computer first envisaged in 1837 is gathering steam.
More than 1,600 people have pledged money and support to build Charles Babbage's Analytical Engine.
Although elements of the engine have been built over the last 173 years, a complete working model of the steam-powered machine has never been made.

India's latest supercomputer unveiled

India's latest supercomputer 'Annapurna' was unveiled at the Institute of Mathematical Sciences (IMSc) on Friday.
Atomic Energy Commission chairman Srikumar Banerjee unveiled the country's seventh fastest high-performance computation (HPC) cluster having 1.5 Tera Byte (TB) memory and 30 TB storage space cluster capacity.

Supercomputing has helped astrophysicists create massive models of the universe, but such simulations remain out of reach for many in the United States and around the world. That could all change after a successful test allowed scientists in Portland, Ore. to watch a Chicago-based simulation of how ordinary matter and mysterious dark matter evolved in the early universe.
The streaming event also took place in real-time, which means that teams in both Chicago and Portland could have theoretically played together in the simulation as easily as PC or console video gamers play together in online games.

NASA Supercomputer Ranks Among World's Fastest
After a recent upgrade, NASA's premiere supercomputer located at Ames Research Centre, Moffett Field, California, has garnered the sixth spot on the Top500 list of the world's most powerful computers. The announcement was made Nov. 17, 2009 at the International Conference for High-Performance Computing, Networking, Storage, and Analysis (SC09) in Portland, Oregon.
The Pleiades supercomputer is an SGI® Altix® ICE system with 14,080 Intel® Xeon® quad-core processors (56,320 cores, 110 racks) running at 544 trillion floating point operations per second (teraflops) on the LINPACK benchmark, the industry standard for measuring a system's floating point computing power. One of the most powerful general-purpose supercomputers ever built, Pleiades also features the world's largest InfiniBand® interconnect network.

There is a race to make supercomputers as powerful as possible to solve some of the world's most important problems, including climate change, the need for ultra-long-life batteries for cars, operating fusion reactors with plasma that reaches 150 million degrees Celsius and creating bio-fuels from weeds and not corn.
Supercomputers allow researchers to create three-dimensional visualizations, not unlike a video game, to run endless "what-if" scenarios with increasingly finer detail. But as big as they are today, supercomputers aren't big enough -- and a key topic for some of the estimated 11,000 people now gathering in Portland, Ore. for the 22nd annual supercomputing conference, SC09, will be the next performance goal: an exascale system.

The National University of Defence Technology (NUDT) unveiled Thursday China's fastest supercomputer, which could rival the world's most powerful computing devices.
The supercomputer, named Tianhe, meaning Milky Way, is theoretically able to do more than 1 quadrillion calculations per second (one petaflop) at peak speed.

Science at the Petascale: Roadrunner Results Unveiled
The world's fastest supercomputer, Roadrunner, at Los Alamos National Laboratory has completed its initial "shakedown" phase doing accelerated petascale computer modelling and simulations of a variety of unclassified, fundamental science projects.
The Roadrunner system is now beginning its transition to classified computing to assure the safety, security, and reliability of the U.S. nuclear deterrent. 
Capitalising on this national security investment, 10 unclassified projects were selected for this opportunity to use Roadrunner, a hybrid-architecture, 1.105 petaflop/s computing system, during a six-month period that ended in September 2009.

Scientists use Worlds Fastest Supercomputer to Model Origins of the Unseen Universe
Understanding dark energy is the number one issue in explaining the universe, according to Salman Habib, of the Laboratory's Nuclear and Particle Physics, Astrophysics and Cosmology group.

"Because the universe is expanding and at the same time accelerating, either there is a huge gap in our understanding of physics, or there is a strange new form of matter that dominates the universe -- 'dark energy' -- making up about 70 percent of it. In addition, there is five times more of an unknown 'dark matter' than there is ordinary matter in the universe, and we know it's there from many different observations, most spectacularly, we've seen it bend light in pictures from the Hubble Space Telescope, but its origin is also not understood" - Salman Habib

Even though it's looking at only a small segment of the "accessible" universe, Habib's "Roadrunner Universe" model requires a petascale computer because, like the universe, it's mind-bendingly large. The model's basic unit is a particle with a mass of approximately one billion suns (in order to sample galaxies with masses of about a trillion suns), and it includes 64 billion and more of those particles.
