The Problem With the Top500 Supercomputer List 175

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.

Windows Cluster Hits a Petaflop, But Linux Retains Top-5 Spot 229

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."

China Makes World's Fastest Supercomputer 222

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."

Supercomputer Sets Protein-Folding Record 63

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."

NASA Creates an Alien's Eye View of Solar System 53

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."

IBM Warns of China Closing the Supercomputer Gap 238

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."

Homebrew Cray-1 140

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."

Low Energy Supercomputing 159

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."

Supercomputing, There's an App For That 66

aarondubrow writes "Researchers at MIT have created an experimental system for smart phones that allows engineers to leverage the power of supercomputers for instant computation and analysis. The team performed a series of expensive high-fidelity simulations on the Ranger supercomputer to generate a small "reduced model" which was transferred to a Google Android smart phone. They were then able to solve engineering and fluid flow problems on the phone and visualize the results interactively. The project proved the potential for reduced order methods to perform real-time and reliable simulations for complicated problems on handheld devices."

IBM Supercomputer Cooled With Hot Water 89

1sockchuck writes "IBM has deployed an innovative supercomputer cooled by hot water in a Zurich computer lab. The Aquasar supercomputer employs a chip-level liquid cooling system that can use water at temperatures as high as 60 degrees C (140 degrees F), and as a result consumes up to 40 percent less energy than a comparable system using room-level air-cooling. The system also uses waste heat to provide warmth to buildings, reducing Aquasar's carbon footprint even further."

'Telecommuting' In Formula 1 90

flewp writes "This New York Times article on Formula 1 racing gives some insight into the workings of one of the most high-tech sports on the planet — consider that a few years ago, Sauber's supercomputer ranked toward the top of all the supercomputers in Europe. The teams bring to each race dozens of mechanics, support personnel, etc.; but back at their home bases, perhaps thousands of miles away, countless more engineers work (with the help of gobs of computing power) to give each team that extra edge."

Renewable Energy To Power Aussie SKA 48

schliz writes "New solar and geothermal energy facilities are being built in Australia to provide sustainable energy for the region's Square Kilometer Array (SKA) bid. The Australian Government yesterday announced A$47.3m in funding for a full-scale, hybrid solar and diesel plant for the Australian SKA Pathfinder (ASKAP) at the Murchison Radio-astronomy Observatory, and geothermal energy facilities for the Pawsey High-Performance Computing Centre, where data from SKA radio telescopes would be processed. ASKAP is part of the Australasian bid to host the $2.5 billion Square Kilometre Array (SKA), which involves 20 countries and will investigate galaxy evolution, dark matter, and the existence of life. IBM expects the whole of the SKA to produce an exabyte of data per day."

Mobile Phones vs. Supercomputers of the Past 247

An anonymous reader writes "The recently published Top 500 list of the world's fastest supercomputers is based on the Linpack benchmark developed decades ago by Jack Dongarra. This same test has been ported to Android mobile phones, which means that we can compare the performance of our phones against that of the supercomputers of the past. For example, a tweaked Motorola Droid can hit 52 Mflop/s, which is more than 15 times faster than the CPUs used in the 1979 Cray-1." But even today's most powerful cellphones don't come with an integrated bench.

NSF Gives Supercomputer Time For 3-D Model of Spill 102

CWmike writes "Scientists have embarked on a crash effort to use one the world's largest supercomputers to create 3-D models to simulate how BP's massive Gulf of Mexico oil spill will affect coastal areas. Acting within 24 hours of receiving a request from researchers, the National Science Foundation late last week made an emergency allocation of 1 million compute hours on a supercomputer at the Texas Advanced Computing Center to study how BP's gusher will affect coastlines. The computer model they are working on 'has the potential to advise and undergird many emergency management decisions that may be made along the way, particularly if a hurricane comes through the area,' said Rick Luettich, a professor of marine sciences and head of the Institute of Marine Sciences at the University of North Carolina in Chapel Hill, who is one of the researchers on this project. Meanwhile, geographic information systems vendor ESRI has added a social spin to GIS mapping of the BP oil spill."

Startup's Submerged Servers Could Cut Cooling Costs 147

1sockchuck writes "Are data center operators ready to abandon hot and cold aisles and submerge their servers? An Austin startup says its liquid cooling enclosure can cool high-density server installations for a fraction of the cost of air cooling in traditional data centers. Submersion cooling using mineral oil isn't new, dating back to the use of Fluorinert in the Cray 2. The new startup, Green Revolution Cooling, says its first installation will be at the Texas Advanced Computing Center (also home to the Ranger supercomputer). The company launched at SC09 along with a competing liquid cooling play, the Iceotope cooling bags."

IBM Claims Breakthrough Energy-Efficient Algorithm 231

jitendraharlalka sends news of a claimed algorithmic breakthrough by IBM, though from the scant technical detail provided it's hard to tell exactly how important the development might be. IBM apparently presented its results yesterday at the Society for Industrial and Applied Mathematics conference in Seattle. The breathless press release begins: "IBM Research today unveiled a breakthrough method based on a mathematical algorithm that reduces the computational complexity, costs, and energy usage for analyzing the quality of massive amounts of data by two orders of magnitude. This new method will greatly help enterprises extract and use the data more quickly and efficiently to develop more accurate and predictive models. In a record-breaking experiment, IBM researchers used the fourth most powerful supercomputer in the world... to validate nine terabytes of data... in less than 20 minutes, without compromising accuracy. Ordinarily, using the same system, this would take more than a day. Additionally, the process used just one percent of the energy that would typically be required."

Virtualizing a Supercomputer 57

bridges writes "The V3VEE project has announced the release of version 1.2 of the Palacios virtual machine monitor following the successful testing of Palacios on 4096 nodes of the Sandia Red Storm supercomputer, the 17th-fastest in the world. The added overhead of virtualization is often a show-stopper, but the researchers observed less than 5% overhead for two real, communication-intensive applications running in a virtual machine on Red Storm. Palacios 1.2 supports virtualization of both desktop x86 hardware and Cray XT supercomputers using either AMD SVM or Intel VT hardware virtualization extensions, and is an active open source OS research platform supporting projects at multiple institutions. Palacios is being jointly developed by researchers at Northwestern University, the University of New Mexico, and Sandia National Labs." The ACM's writeup has more details of the work at Sandia.
