Reader Dr.Who notes that an Australian research team using IBM's Blue Gene/P supercomputer has calculated the sixty-trillionth binary digit of Pi-squared, a task which took several months of processing. Snipping from the article, the Dr. writes: "'A value of Pi to 40 digits would be more than enough to compute the circumference of the Milky Way galaxy to an error less than the size of a proton.' The article goes on to cite use of computationally complex algorithms to detect errors in computer hardware. The article references a blog which has more background. Disclaimers: I attended graduate school at U.C. Berkeley. I am presently employed by a software company that sells an infrastructure product named PI."

The Air Force's Research Lab in Rome, NY. has one of the cheapest supercomputers ever made, and best of all over 3,000 of your friends can play Tekken on it. The computer is made from 1,716 PlayStation 3s linked together, and is used to process images from spy planes. From the article: "The Air Force calls the souped-up PlayStations the Condor Supercomputer and says it is among the 40 fastest computers in the world. The Condor went online late last year, and it will likely change the way the Air Force and the Air National Guard watch things on the ground." We covered this story back in December when the Condor first went online.

rubycodez writes "The Tianhe-1A system will be the last Chinese supercomputer to use imported Intel and AMD processors. By years end, China's own 64 bit MIPS-compatible 65nm 8-core 1GHz version of the Godsen (Longsoon family) processors will be used, including 10,000 of them for the 'Dawning 6000' supercomputer. Yes, the chips can and usually do run GNU/Linux, but also can run FreeBSD, OpenBSD, and NetBSD."

schliz writes "Salk Institute director Terrence Sejnowski has called for more power-efficient, parallel computing architecture to support future robots that could keep up with the human brain. While human brains had 100 billion neurons and required only 20 Watts of energy, today's most powerful supercomputer, the 2.57 PFlop Chinese Tianhe-1A, requires four megawatts, and still has trouble with vision, motion, and 'common sense,' he said."

HansonMB writes with this bit from Motherboard: "Back in September, Motherboard ventured into the English countryside to listen to the universe. There lives a brand new piece of Europe's already-massive Low Frequency Radio Array radio telescope: a clever EU-wide installation that uses low-tech antennas and supercomputer-power data processing to transform into a giant mega-telescope, absorbing cosmic radio waves from the full sky." That was then; now, says the article, "In the past month, using signals from the new station, LOFAR has delivered its first EU-UK radio 'pictures.'"

CWmike writes "First it was China's 'big hole' sighting that brought us the supercomputing race. Now China is building a city-sized cloud computing and office complex that will include a mega data center, one of the projects fueling that country's double-digit growth in IT spending. The entire complex will cover some 6.2 million square feet, with the initial data center space accounting for approximately 646,000 square feet, says IBM, which is collaborating with a Chinese company to build it. A Sputnik moment? Patrick Thibodeau reports that these big projects, whether supercomputers or sprawling software development office parks, can garner a lot of attention. But China's overall level of IT spending, while growing rapidly, is only one-fifth that of the US."

eldavojohn writes "Coinciding with the 32nd anniversary of the Iranian revolution, Iran opened a center to receive satellite images built 'entirely by Iranian engineers.' Iran promised that by the end of their year (March of 2011) they would launch two observational satellites: Fajr (Dawn) and Rasad-1 (Observation-1). You might recall two years ago when they launched Omid, which completed about 700 orbits in two weeks. There are reports that new launch rockets will be revealed in February to launch the new satellites — all equipment is claimed to be entirely Iranian made. Iranian media is reporting that one of the satellites 'carries remote measuring equipment that would be used in meteorology and identifying sea borders.' The Iranian Student News Agency says Explorer 4 (Kavoshgar 4) is meant to transport humans and other living organisms into space, and that the sensory on the satellites 'is able to find gas and oil resources, identify coal mines, jungles and agricultural products as well as salty-marsh and contaminated environments.' These rapid fire achievements are not the only bragging Iran has done as of late; they also claim 'new gamma radiation units for medical treatments and a supercomputer billed as among the top 500 most powerful in the world. But, fact or fiction aside, the satellites have old enemies speculating."

kgeiger writes "In the Feb. 2011 issue of IEEE Spectrum online, Peter Kogge, an IEEE Fellow and professor of computer science and engineering at the University of Notre Dame, outlines why we won't see exaflops computers soon. To start with, consuming 67 MW (an optimistic estimate) is going to make a lot of heat. He concludes, 'So don't expect to see a supercomputer capable of a quintillion operations per second appear anytime soon. But don't give up hope, either. [...] As long as the problem at hand can be split up into separate parts that can be solved independently, a colossal amount of computing power could be assembled similar to how cloud computing works now. Such a strategy could allow a virtual exaflops supercomputer to emerge. It wouldn't be what DARPA asked for in 2007, but for some tasks, it could serve just fine.'"

An anonymous reader writes "Ok, this was just a practice round. But in a short demonstration today IBM's Jeopardy-playing supercomputer, a whiz by the name of Watson, thoroughly bested two talented human contestants. IBM has been working on this artificial intelligence project for years to prove that a computer can be programmed to understand conversational speech and wordplay. In today's demo, Watson seems to have proved the point: it started out on a roll in the category 'Chicks Dig Me,' about women and archaeology. The real man versus machine face-off (in which the same contestants compete for a $1 million prize) will be taped tomorrow, and aired in February."

dcblogs writes "The White House's science advisors, in a report last week, said a petaflop-by-petaflop race to achieve number one on the Top500 could prove costly and divert money from supercomputing research. 'While it would be imprudent to allow ourselves to fall significantly behind our peers with respect to scientific performance benchmarks that have demonstrable practical significance, a single-minded focus on maintaining clear superiority in terms of flops count is probably not in our national interest,' the report said (PDF). It is urging the supercomputing community to expand its benchmark measures beyond the Top500's Linpack. It says the Graph500, for data-intensive applications involving the rapid execution of graph operations, 'will be more relevant,' but also acknowledges that it will difficult to rely on any one measure."

angry tapir writes "The global race for supercomputing power continues unabated: Germany's Bavarian Academy of Science has announced that it has contracted IBM to build a supercomputer that, when completed in 2012, will be able to execute up to 3 petaflops, potentially making it the world's most powerful supercomputer. To be called SuperMUC, the computer, which will be run by the Academy's Leibniz Supercomputing Centre in Garching, Germany, will be available for European researchers to use to probe the frontiers of medicine, astrophysics and other scientific disciplines."

digitaldc writes with this excerpt from Gamasutra: "The Air Force Research Laboratory (AFRL) has connected 1,760 PlayStation 3 systems together to create what the organization is calling the fastest interactive computer in the entire Defense Department. The Condor Cluster, as the group of systems is known, also includes 168 separate graphical processing units and 84 coordinating servers in a parallel array capable of performing 500 trillion floating point operations per second (500 TFLOPS), according to AFRL Director of High Power Computing Mark Barnell."

angry tapir writes "The Top500 list of supercomputers is dutifully watched by high-performance computing participants and observers, even as they vocally doubt its fidelity to excellence. Many question the use of a single metric — Linpack — to rank the performance of something as mind-bogglingly complex as a supercomputer. During a panel at the SC2010 conference this week in New Orleans, one high-performance-computing vendor executive joked about stringing together 100,000 Android smartphones to get the largest Linpack number, thereby revealing the 'stupidity' of Linpack. While grumbling about Linpack is nothing new, the discontent was pronounced this year as more systems, such as the Tianhe-1A, used GPUs to boost Linpack ratings, in effect gaming the Top500 list." Fortunately, Sandia National Laboratories is heading an effort to develop a new set of benchmarks. In other supercomputer news, it turns out the Windows-based cluster that lost out to Linux stumbled because of a bug in Microsoft's software package. Several readers have also pointed out that IBM's Blue Gene/Q has taken the top spot in the Green500 for energy efficient supercomputing, while a team of students built the third-place system.

Twice a year, Top500.org publishes a list of supercomputing benchmarks from sites around the world; the new results are in. Reader jbrodkin writes "Microsoft says a Windows-based supercomputer has broken the petaflop speed barrier, but the achievement is not being recognized by the group that tracks the world's fastest supercomputers, because the same machine was able to achieve higher speeds using Linux. The Tokyo-based Tsubame 2.0 computer, which uses both Windows and Linux, was ranked fourth in the world in the latest Top 500 supercomputers list. While the computer broke a petaflop with both operating systems, it achieved a faster score with Linux, denying Microsoft its first official petaflop ranking." Also in Top-500 news, reader symbolset writes with word that "the Chinese Tianhe-1A system at the National Supercomputer Center in Tianjin takes the top spot with 2.57 petaflops. Although the US has long held a dominant position in the list things now seem to be shifting, with two of the top spots held by China, one by Japan, and one by the US. In the Operating System Family category Linux continues to consolidate its supercomputing near-monopoly with 91.8% of the systems — up from 91%. High Performance Computing has come a long way quickly. When the list started as a top-10 list in June of 1993 the least powerful system on the list was a Cray Y-MP C916/16526 with 16 cores driving 13.7 RMAX GFLOP/s. This is roughly the performance of a single midrange laptop today."

shmG writes "China has replaced the United States as the maker of the world's fastest supercomputer. A Chinese research center has made the world's faster super computer — named as Tianhe-1A, which was released at a national conference on high-performance computers (HPC) in China. Made at a cost of over $88 million, Tianhe-1A is theoretically able to do more than 1 quadrillion calculations per second (one petaflop) at peak speed. Tianhe-1A 's peak performance reaches 1.206 petaflops, and it runs at 563.1 teraflops (1,000 teraflops is equal to one petaflop) on the Linpack benchmark."

Nicros writes with this snippet from Nature News: "A specially designed supercomputer named Anton has simulated changes in a protein's three-dimensional structure over a period of a millisecond — a time-scale more than a hundred-fold greater than the previous record. ... The simulations revealed how the proteins changed as they folded, unfolded and folded again. 'The agreement with experimental data is amazing,' says Chandra Verma, a computational structural biologist at the Bioinformatics Institute of the Agency for Science, Technology and Research in Singapore. Simulating the basic pancreatic trypsin inhibitor over the course of a millisecond took Anton about 100 days — roughly as long as computers spent toiling over previous simulations that only spanned 10 microseconds."

Flash Modin writes "Using the Discover supercomputer — which is capable of 67 trillion calculations per second — astronomers at NASA Goddard have created a series of images of what our solar system would look like to an alien astronomer at various points in time. Their simulations track the interactions of 75,000 dust grains in the Kuiper Belt, and show that while the planets would be too dim to detect directly, aliens could deduce the presence of Neptune from its effects on the icy region. Strikingly, the images resemble one taken by Hubble of the star Fomalhaut. NASA has put out a cute video to go with the announcement as well."

eldavojohn writes "China is digging a massive hole to house a computer building with the intent of usurping the United States' lead in the field of supercomputing, claims IBM. As of earlier this year, Oak Ridge Lab was beating China's Shenzhen Center. But now, an IBM representative has said to a Washington, DC forum, 'You have sovereign nations making material investments of a tremendous magnitude to basically eat our lunch, eat our collective lunch.' China has long been a contender in this regard, and Europe and Japan have similar goals to build an exascale supercomputer. To achieve this by 2020, the US will need to focus on 'co-design,' where hardware is developed in tandem with every other aspect of the computer, from applications down to optics. This isn't the first time a 'space race' style supercomputing push has been spurred by international competitiveness."

egil writes "Chris Fenton built his own fully functional 1/10 scale Cray-1 supercomputer. True to the original, it includes the couch-seat, but is also binary compatible with the original. Instead of the power-hungry ECL technology, however, the scale model is built around a Xilinx Spartan-3E 1600 development board. All software is available if you want to build one for your own living room. The largest obstacle in the project is to find original software."

Faith Singer at TACC writes "The term 'supercomputing' usually evokes images of large, expensive computer systems that calculate unfathomable algorithms and run on enough energy to support a small city. Now, imagine a supercomputer, but run on the electrical equivalent of three standard-size coffee-makers. This year's international supercomputing conference, SC10, will feature the Student Cluster Competition that challenges students to build, maintain, and run the most-cutting edge, commercially available high-performance computing (HPC) architectures on just 26 amps."
