Tianhe-1 supercomputer restarted in Tianjin after the blast

The computing center, located about 1.5 kilometers from the explosion site, was shut down immediately after the blast late last Wednesday.
Tianhe-1 provides data services to more than 300 organizations across China, including several universities and banks.

US Titan bests Sequoia to become world's fastest supercomputer

The US once again has the world's top supercomputer.
The Titan, a Cray XK7 system installed at the Oak Ridge National Laboratory (ORNL) in Tennessee, has been named the fastest supercomputer in the world in the 40th edition of the twice-annual Top500 List.

Babbage builders turn down Kickstarter

An ambitious 10-year project to build the world's first computer, the Analytical Engine, will rely on donations via the website JustGiving.
Although Kickstarter, the crowdfunding website, is about to launch in the UK, the team say the 10% commission it charges for its service is too high.

eResearch SA launches game-changing supercomputer

South Australia's most powerful public research high performance computing (HPC) system, 'The Tizard Machine', was launched today by Science and Information Economy Minister Tom Kenyon. 
The eResearch SA computer will be a game changer for those researchers in our state performing some of the most complex calculations and who require the use of the most powerful supercomputers that we can build.

IBM's Sequoia has taken the top spot on the list of the world's fastest supercomputers for the US.
The newly installed system trumped Japan's K Computer made by Fujitsu which fell to second place.
It is the first time the US can claim pole position since it was beaten by China two years ago.

Virginia Tech's Wu Feng unveils HokieSpeed, a new powerful supercomputer for the masses

Virginia Tech crashed the supercomputing arena in 2003 with System X, a machine that placed the university among the world's top computational research facilities. Now comes HokieSpeed, a new supercomputer that is up to 22 times faster and yet a quarter of the size of X, boasting a single-precision peak of 455 teraflops, or 455 trillion operations per second, and a double-precision peak of 240 teraflops, or 240 trillion operations per second.
That's enough computational capability to place HokieSpeed at No. 96 on the most recent Top500 List, the industry-standard ranking of the world's 500 fastest supercomputers. More intriguing is HokieSpeed's energy efficiency, which ranks it at No. 11 in the world on the November 2011 Green500 List, a compilation of supercomputers that excel at using less energy to do more. On the Green500 List, HokieSpeed is the highest-ranked commodity supercomputer in the United States.

The European Union is all set to fund a 900 million-pound scheme to produce a computer system that could predict spread of diseases and impending financial meltdowns.
The Living Earth Simulator Project (LES), which has been backed by leading scientists, aims to "simulate everything" on the planet, using anything from tweets to government statistics to map out social trends and predict the next economic crisis.

Fujitsu has built the fastest supercomputerer at 8.2 petaflops the K supercomputer

The previous fastest machine was the Chinese computer Tianhe-1A, which was clocked at 2.507 petaflops.
The rankings for the world's fastest computers are kept by a professor of electrical engineering and computer science at the University of Tennessee at Knoxville, one Jack Dongarra.
The top 500 machines is based on how fast they run Linpack, a benchmark application developed to solve a dense system of linear equations.
Jaguar, a Cray supercomputer at the U.S. Department of Energy's (DOE's) Oak Ridge National Laboratory, at No. 3 with 1.75 petaflop/s.
