jsse writes "ComputerWorld (Hong Kong) has an article about Chinese Academy of Sciences building a supercomputer which has been shown in benchmark tests to process up to 10 trillion floating-point operations per second (TFLOPS) and is expected to take a spot on the list of the world's ten most powerful supercomputers for the first time. The computer is a cluster of 2,560 Opteron 800 series processors from Advanced Micro Devices Inc. (AMD) contained in 640 nodes of four processors each. AMD has announced the project last year when the cluster was building."

caek writes "If you've played Sim City you've wrestled with one of the problems faced by supercomputer designers. Unfortunately there's no GameFAQs.com for the technical staff at Japan's Earth Simulator or Srinidhi Varadarajan and colleagues at Virginia Tech. True enough, they won't have to deal with rising crime or Godzilla but, as hinted at in a recent paper in Journal of Physics A, the physical layout of a massively parallel supercomputer is fundamentally the same problem as minimizing the time commuters spent stuck in traffic jams. Read the rest of my kuro5hin article for a popular explanation."

Homey R writes "As I'll be joining the staff there in a few months, I'm very excited to see that Oak Ridge National Lab has won a competition within the DOE's Office of Science to build the world's fastest supercomputer at Oak Ridge National Lab in Oak Ridge, Tennessee. It will be based on the promising Cray X1 vector architecture. Unlike many of the other DOE machines that have at some point occupied #1 on the Top 500 supercomputer list, this machine will be dedicated exclusively to non-classified scientific research (i.e., not bombs)." Cowards Anonymous adds that the system "will be funded over two years by federal grants totaling $50 million. The project involves private companies like Cray, IBM, and SGI, and when complete it will be capable of sustaining 50 trillion calculations per second."

Designadrug writes "This story at the BBC details how the worlds third largest supercomputer (conditions apply) lives at Weta Digital - the company that provided CGI effects for The Lord of the Rings movies. The article also goes on to discuss the 500 TeraBytes of data generated for the films and how the epic Battle of Pelennor Fields almost defeated the film itself."

Joanne Pransky's tongue is firmly in her cheek a fair amount of the time as she answers your questions, but much of what she says is thought-provoking, especially in light of speculations like Marshall Brain's Robotic Nation essays about the inevitable spread of robotic devices in our society.

jagger writes "Linux clustering was touted as the next big thing by many vendors last week at ClusterWorld Conference & Expo 2004. But supercomputer vendor Cray Inc. scoffed at the notion of putting Linux clusters in the high-performance computing (HPC) category. "Despite assertions made by Linux vendors, a Linux cluster is not a high performance computer," said Dr. Paul Terry, CTO of Cray Canada."

aspelling quotes a story that says " Hundreds of area technophiles wired their computers together in an attempt to generate computing power on a par with the world's strongest supercomputers. Organizers hoped to break into the ranks of the world's top 500 supercomputers through the event, which they called "Flashmob I."

TheInternet writes "According to CNET News, IBM has made a series of announcements regarding the opening-up of the Power chip architecture. The story lacks technical details, but apparently, IBM is going to divulge more information about Power/PowerPC, and expects collaboration from the industry on the future of the chip. Nick Donofrio is quoted as saying: 'We will free electronics manufacturers from the limitations of proprietary microprocessor architectures', and Red Hat and Sony are two companies listed as taking part. Power5 was also shown, as was the Blue Gene/L supercomputer, using 32 500MHz processors to achieve 128 gigaflops."

The first Slashback in a while, with updates and reactions to previous Slashdot stories, including a Flash-mod supercomputing reminder, the upside of microwave-tested currency, CUPS' user-interface foibles, an alternative to MD5 sums, and more. Read on for the details.

dan of the north writes "The NY Times (free reg yyy bbb) is running an article on flash mob computing. More info on the first event in SF on April 3, 2004. The goal is to run Linpack and "build a home-brew computer powerful enough to be added to a list of the world's 500 fastest computers." Minimum requirements are 1.3 GHZ Pentium III/AMD equivalent or better with 256MB of RAM, a 100 Base-T network connection and a CD-ROM - laptops preferred. "After taking a shot at a speed record, the computer will be reorganized to serve as the host of a giant multiplayer video game tournament." Cool... a 2fer!"

carl67lp writes "With all the hype surrounding Dan Brown's The DaVinci Code, I decided to travel to the bookstore to purchase the novel. However, while looking at the "New in Paperback" section, I happened across Brown's Digital Fortress and read the back cover quickly. It was exactly what I was looking for: a thriller with science (mathematics and cryptography), technology (a 3-million processor supercomputer), and intrigue. I devoured the nearly-400-page book in less than two days. But I left feeling a bit disappointed when looking back on the overall picture." Read on for Anderson's reasoning.

Graff writes "Now that Apple has come out with the Xserve G5, Virginia Tech has been swapping out parts of their 'System X' supercomputer for the more compact 1U Xserves. MacMall is selling some of those System X component G5 systems with an approximate $200 savings and an extra 512 megs of RAM over a normal G5. You can read more about it at MacCentral."

An anonymous reader writes "Virginia Tech officially announced that they will be migrating their G5 Supercomputer from PowerMac G5s to Xserves. According to the article, the Xserve G5s will reduce power consumption, heat production and decrease the system size by a factor of three. The pricing of the upgrade is still being determined, and according to Srinidhi Varadarajan, they are working on getting "very good homes" for the PowerMac G5s which will be replaced."

no_demons writes "Along with a selection of other goodies, Apple also unveiled their Xgrid clustering technology from their advanced computation group today. Xgrid can turn a number of networked Macs into a supercomputer, detects nodes automagically via Rendezvous, and can run in or out of a screensaver mode. You can download a technology demo (including a BLAST test app) here."

WillOutPower writes "Sun is inviting Cray (of supercomputer fame) and IBM (needs no introduction...) to join and create a new intermediate run-time language for high-performance computing. Java's bytecode, Java Grande, and Microsoft's IL language for the Common Language Runtime, it seems a natural progression. I wonder if the format will be in XML? Does this mean ubiquitous grid computing? Maybe now I won't have to write my neural network in C for performance :-)"

Licensed2Hack writes "The Cooperative Association for Internet Data Analysis (CAIDA), part of the San Diego Supercomputer Center at the University of California, San Diego has an analysis of the recent DDOS on SCO.com. Netcraft also has more information in their article and analysis graphs. Seems SCO was hit with a 50,000 packet-per-second SYN flood peak, which yields approximately 20 Mb/s each way, or about the capacity of a DS3 line."

dex writes "Tom Perrine and Devin Kowatch of the San Diego Supercomputer Center have issued "Teracrack: Password cracking using TeraFLOP and PetaByte Resources" (PDF, HTML version via Google). Using SDSC's prodigious computing facilities, they precomputed 207 billion crypt() hashes in 80 minutes."

Bob Plankers writes "By now we've all heard about IBM's Blue Gene/L, LLNL's remarkable new supercomputer which is intended to be the fastest supercomputer on Earth when done (360 TeraFLOPS). IBM has released some new photos of the prototype, and renditions of the final cluster. Note that the racks are angled in order to permit hot air to escape vertically and reduce the need for powered cooling. The machine uses custom CPUs with dual PowerPC 440 processing cores, four FPUs (two per core), five network controllers, 4 MB of DRAM, and a memory controller onboard. The prototype has 512 CPUs running at 700 MHz, and when finished the entire machine will have 65536 dual-core CPUs running at 1 GHz or more. Stephen Shankland's ZDnet article also mentions that the system runs Linux, but not on everything: 'Linux actually resides on only a comparatively small number of processors; the bulk of the chips run a stripped-down operating system that lets it carry out the instructions of the Linux nodes.'"

mE123 writes "It would seem that IBM is trying to change what we all think of as super computers. Their new Blue Gene family of super computers is meant to be 6 times faster, consume 1/15 of the power and be 1/10 the size of current models. The prototype is already number 73 (with 2 teraflops) on the list of the most powerful super computers and it's only "roughly the size of a 30-inch television". They are hoping to be able to make it up to 360 Teraflops using only 64 racks." We covered this a bit earlier, but without the level of details.
