TeraGrid v. Distributed Computing 124

Nevyan writes "After three years of development and nearly a hundred million dollars the TeraGrid has been running at or above most peoples expectations for such a daunting project. On January 23, 2004 the system came online and provided 4.5 teraflops of computing power to scientists across the country. However, the waiting list for TeraGrid is long, including a bidding process through the National Science Foundations (NSF's) Partnerships for Advanced Computational Infrastructure (PACI) and many scientists with little funding but bright ideas are being left behind. While the list of supercomputer sites and peak power is growing how is the world of Distributed Computing faring? "

Army Contractor To Build A 1566 Xserve Cluster 465

olePigeon (Wik) writes "MacCentral has an interesting article on a new computer cluster. From the article: 'Apple Computer Inc. will announce on Monday the sale of 1566 dual processor 1U rack-mount 64-bit Xserve G5 servers to COLSA Corp., which will be used to build what is expected to be one of the fastest supercomputers in the world. The US$5.8 million cluster will be used to model the complex aero-thermodynamics of hypersonic flight for the U.S. Army.'" alset_tech was one of the many readers to point to CNET's version of the story.

Top 500 Supercomputer List Released 167

sundling writes "The heavily anticipated Top 500 Supercomputer list has been released. There is a Sevenfold increase in AMD Opteron processors on the list. Two sections of an IBM prototype took spots in the top 10 and the famous Apple cluster didn't make the list, because it was out of service for hardware upgrades. When complete, the new IBM cluster is sure to take the top spot from the Earth Simulator."

The Technology Behind Formula One 586

axlrosen writes "An article in the NY Times about the technology behind Formula One. The wealthiest teams arm themselves with powerful advantages, almost entirely centering on computing controls in the cars and computer simulation in design. Car data is sent in multi-megabyte wireless bursts each time the team's cars flash past the pits, often in excess of 200 miles an hour. It is simultaneously sent over the Internet to a larger data center in Maranello, Italy, where more complex analysis is done. AMD is expected to supply a supercomputer roughly as fast as the world's 10th most powerful machine to the Swiss-based Sauber Petronas racing team... I love the crazy steering wheel - anyone know what all those buttons and knobs do?"

China to Crack Supercomputer Top Ten List 290

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."

Using Math To Design Cities And Supercomputers 40

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."

World's Fastest Supercomputer To Be Built At ORNL 230

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."

Cray CTO: Linux clusters don't play in HPC 435

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."

IBM Plans Collaboration On Power Architecture 198

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."

Flash Mob Supercomputer? 259

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!"

Digital Fortress 217

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.

New Intermediate Language Proposed 443

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 :-)"
