coolmacdude writes "Well it seems that the early estimates were a bit overzealous. According to preliminary test results (in postscript format) on the full range of CPUs at Virginia Tech, the Rmax score on Linpack comes in at around 7.4 TFlops. This puts it at number four on the Top 500 List. It also represents an efficiency of about 44 percent, down from the previous result of 80 achieved on a subset of the computers. Perhaps in light of this, apparantly VT is now planning to devote an additional two months to improve the stability and efficiency of the system before any research can begin. While these numbers will no doubt come as a disappointment for Mac zealots who wanted to blow away all the Intel machines, it should still be noted that this is the best price/performance ratio ever achieved on a supercomputer. In addition, the project was successful at meeting VT's goal of developing an inexpensive top 5 machine. The results have also been posted at Ars Technica's openforum."

An anonymous reader writes "According to the Austin Business Journal, Dell's 3-teraflop, 600 server supercomputer cluster cost the University of Texas $38 million. As The Apple Turns has pointed out that this is 7 times the cost (and a quarter of the power) of Apple's cluster at Virginia Tech! " Update: 10/14 17:56 GMT by M : worm eater writes "The Register has posted a correction to the widely-reported story that a 3.7 terraflop Dell cluster cost the University of Texas $38 million. As it turns out, the computer cost $3 million, vs. $5.2 million for the 17.6 terraflop Mac G5 cluster at Virginia Tech."

Don Stratton writes "This is the coolest thing I have seen anyone do with a Pocket PC... ever! Well-known Pocket PC developers SPB Software House, located in Russia, have come up with a very interesting spin on computing clusters. The short version is they connected 12 Pocket PCs together in the first known 'supercomputer cluster' of its type and had it calculate the old '3n + 1' problem. It was just done for fun, and not intended to seriously compete with desktop computers, but it does point out some interesting possiblilities for the future of handhelds with wireless connectivity working in ad-hoc computing clusters."

GeoGreg writes "The BBC is reporting that the Japanese Earth Simulator supercomputer is producing results showing that it is possible to model climate down to the level of severe weather events such as hurricanes. This computer has been discussed on Slashdot previously, and it sounds like at least some of the hype around this beastie was justified."

hotsauce writes "The BBC is reporting that CERN (the guys who invented the Web) are working on a virtual supercomputer called the Grid. The Grid taps computing power from 12 countries to process data from a new supercollider that will simulate parts of the Big Bang. Phase One of the Grid just went online."

danigiri writes "Detailed notes about a presentation at Virginia Tech are posted by by an attending student. copied most of the slides of the facts presentation and wrote down their comments. He wrote some insightful notes and info snippets, like the fact that Apple gave the cheapest deal of machines with chassis, beating Dell, IBM, HP. They are definitely going to use some in-house fault-tolerance software to prevent the odd memory-bit error on such a bunch of non-error-tolerant RAM and any other hard or soft glitches. The G5 cluster will be accepting first apps around-November." mfago adds, "Apple beat Dell, IBM and others based on Cost vs. Performance alone, and it will run Mac OS X because 'there is not enough support for Linux.'"

CousinVinnie writes "Previously noted in this Slashdot story, the administration of Virginia Tech has announced they're puchasing 1100 G5's (another story) in hopes to build a top-10 supercomputer by October 1. Tech will be spending $5.2 million over five years on the project, which should help it pull in more research money." Maybe VT can use the new computers to beef up their web site.

hype7 writes "ThinkSecret is running a story which might explain exactly why the Dual 2GHz G5 machines have been delayed to the customers that ordered them minutes after the keynote was delivered. Apparently, Virginia Tech has plans to build a G5 cluster of 1100 units. If it manages to complete the cluster before the cut-off date, it will score a Top 5 rank in the Linpack Top 500 Supercomputer List. Both Apple and the University are playing mum on the issue, but there's talk of it all over the campus."

cadfael writes "SCO is reported in the Age as saying they 'Have no plans to sue Linux companies...' This seems to contradict the earlier statements of Chris Sontag. This story also points out how Canopy owns stakes in several other Linux companies, including Linux Networx wheich supplied the supercomputer for Lawrence Livermore Nat Lab. One begins to wonder if the reality of their situation has become clear to them?" Maybe, just maybe, this is the beginning of the end of this mess.

jgercken writes "The Department of Energy's Pacific Northwest National Laboratory has brought online a 11.8 teraflops supercomputer based on the Linux operating system, comprised of ~2,000 Itanium processors, and assembled by HP. Touted to be the fastest unclassified computer in the US, its main duties will be atmospheric chemistry, systems biology, catalysis and materials science."

Hank Dietz writes "At the University of Kentucky, KASY0, a Linux cluster of 128+4 AMD Athlon XP 2600+ nodes, achieved 471 GFLOPS on 32-bit HPL. At a cost of less than $39,500, that makes it the first supercomputer to break $100/GFLOPS. It also is the new record holder for POV-Ray 3.5 render speed. The reason this 'Beowulf' is so cost-effective is a new network architecture that achieves high performance using standard hardware: the asymmetric Sparse Flat Neighborhood Network (SFNN)." Because this was a university project, KASY0 was assembled entirely by unversity students, which while being a source of cheap labor, is also a good way to get a lot of students of involved in a great project.

Bootsy Collins writes "In a brief article, Computer Business Review Online quotes Darl McBride as saying that SCO has been busily identifying Linux end users and is preparing to launch lawsuits against them in order to encourage more such end users to buy licenses from SCO. SCO indicates that they'll start with a company that uses AIX, Dynix and Linux, so as to 'settle several legal arguments in one go.'" Not everyone is going to take the SCO approach sitting down; read on for a story on how (among others) Weta Digital and Australia's Massey University aren't jumping to say Uncle to SCO. Update: 08/20 13:11 GMT by T : Oops! Massey University is in New Zealand, not Australia.

lucasw writes "The Japan Earth Simulator outperformed a computer at Los Alamos (previously the world's fastest) by a factor of three while using fewer, more specialized processors and advanced interconnect technology. This spawned multiple government reports that many suspected would ask for more funding in the U.S. for custom supercomputer architectures and less emphasis on clustering commodity hardware. One report released yesterday suggests a balanced approach."

securitas writes "CNet Asia reports that China is building a 2000-processor supercomputer based on the AMD Opteron 64-bit CPU. The new supercomputer will run a Chinese-designed Linux operating system. Based on current standings, the resulting 10-teraflop machine will make it the third most powerful supercomputer in the world. The Red Grid project is being built by Dawning Information Industry and China's National Research Centre for Intelligent Computing Systems. The Red Grid/Dawning 4000A is expected to be complete by June 2004. But China has competition - weighing in at 40 teraflops, the Cray Red Storm AMD-based 10,000-Opteron supercomputer built for Sandia National Labs will become the supercomputer heavyweight next year.

'No nickname' Ian writes "If you live in Europe you should definitely read this story about a government supercomputer. It's written by Andy McCue from silicon.com and entitled: IT Myths: Does the 'Beast of Brussels' know everything about us? Basically, in Europe there are rumours of an EU-owned super-computer which stores and process information on every European citizen. The piece debunks the rumour and finds out its roots are actually in a work of fiction - but there is some interesting comment from privacy activists who suggest it may not be too wide of the mark. Simon Davis of Privacy International goes so far as to suggest such computer may have existed - if perhaps not on the same 'three storey-high' magnitude."

vaderhelmet writes "Wired has a cool story about how the American Museum of Natural History, funded by the National Science Foundation is using Linux to "construct a pattern of relationships that biologists believe links all of Earth's present and past species -- from the smallest microbe to the largest vertebrate that existed during Earth's 4 billion-year history." They're using their very own homemade supercomputer which ranks in at 107 on the Top 500 supercomputers list. Quote from article: "Linux makes it so easy to create a supercomputer.""

machaut writes "In a ClusterComputing.org article, Jim Gray, director of Microsoft's Bay Area Research Lab, provides an interesting economic analysis for building distributed systems. When do you choose a grid over a cluster or a supercomputer? When does it pay off to move a task to the data vs moving the data to the task? He takes current hardware and networking costs into account to answer those questions."

nado writes "There's a new article on Chessbase.com which has GM John Nunn showing you his chess-orientated PC upgrade to a double Xeon system, with some Fritz benchmarks." Elsewhere in the article, John Nunn discusses the unique computer needs for chess computation: "One of the problems with currently available processors is that they are not particularly well suited to the integer calculations used for chess. A Pentium 4 will be slower at chess than a Pentium 3 of an equivalent clock speed."

Sean Burford writes "The South Australian Partnership for Advanced Computing (SAPAC) has unveiled its new AU$1.7 Million supercomputer named Hydra. It is an IBM 1350 Linux cluster with 126 compute nodes (xSeries 335), 1 head node (xSeries 335), 1 storage node (xSeries 345) and 1 managment node (xSeries 345). Hydra has a peak theoretical performance of 1.2 Teraflops, and has currently benchmarked at 682 Gigaflops. The current benchmark places it in the fastest three supercomputers in Australia and equivalent to the current number 80 in the world. The cluster has a total of 258 2.4Ghz Intel Xeon processors and 258GB of RAM. SAPAC expects to achieve a benchmark closer to 700 Gigaflops with further tuning. Hydra is hosted at The University Of Adelaide, who already host a 40 node cluster of Sun e420 machines."

Roland Piquepaille writes "This article starts with a quote from Douglas Adams: 'The major difference between a thing that might go wrong and a thing that cannot possibly go wrong is that when a thing that cannot possibly go wrong goes wrong, it usually turns out to be impossible to get at or repair.' It is true that machines are becoming more complex and 'intelligent' everyday. Does this mean that they can exhibit unpredictable behavior like HAL, the supercomputer in '2001: A Space Odyssey'? Do we have to fear our PCs? A recent book by Thomas M. Georges, 'Digital Soul: Intelligent Machines and Human Values,' explains how our machines can develop neurosis and what kind of therapy exist.
