wildsurf writes "A post in sci.energy points to recent confirmation of the stable existence of N60 , through supercomputer simulation. Large-scale synthesis of this material could form the basis for tremendously powerful rocket fuel. Here is an in-depth article on the subject. What would you do with a few million liters of this stuff?"

claylikethemud writes "The New York Times reports that Japan has built the world's most powerful supercomputer from "640 specialized nodes that are in turn composed of 5,104" NEC processors. The machine boasts the computing power equivalent to the 20 fastest American supercomputers combined, and with a top speed of 35.6 teraflops, outpaces the next fastest machine, the ASCI White Pacific, by more than factor of five. Applications include climate modeling, global warming prediction, and other non-weapons research."

An anonymous reader wrote in to say "Pacific Northwest National Laboratory (US DOE) signed a $24.5 million dollar contract with HP for a Linux supercomputer. This will be one of the top ten fastest computers in the world. Some cool features: 8.3 Trillion Floating Point Operations per Second, 1.8 Terabytes of RAM, 170 Terabytes of disk, (including a 53 TB SAN), and 1400 Intel McKinley and Madison Processors. Nice quote: 'Today's announcement shows how HP has worked to help accelerate the shift from proprietary platforms to open architectures, which provide increased scalability, speed and functionality at a lower cost,' said Rich DeMillo, vice president and chief technology officer at HP. Read Details of the announcement here or here."

totallygeek writes "Redefining the term vaporware, research scientists at Lost Alamos and Lawrence Livermore Labs detonated two computer simulations. ASCI White, the world's fastest supercomputer, ran the simulations of nuclear explosions. Scientists can now study nuclear weapon replacement components without violating the nuclear test ban, in effect since 1992. Each simulation used more than 6.6 million CPU hours, which would take home machines 1000 years to complete. The data for each experiment was equivalent to 35 times the information available in the Library of Congress. ASCI White currently operates at 12 teraflops, but by early next year, Los Alamos expects to operate at 30 teraflops. The seven month research project ended last Friday, and now the system is ready for use, after its sucessful testing."

jhiv writes: "The National Nuclear Security Administration (NNSA) reports that 'Los Alamos and Lawrence Livermore national laboratories have completed the first full-system three-dimensional simulations of a nuclear weapon's explosion'. The simulations are two of the largest computer simulations ever attempted, each taking weeks to complete on the ASCI White supercomputer. The Los Alamos team used the ASCI Blue Mountain supercomputer to visualize the results. Additional coverage can be found in this story in the Albuquerque Journal."

Cameron asks: "Has anyone tried to make a Linux cluster on a typical company/school network? I am trying to make a Linux cluster by taking bootable CDs and putting them in computers on an existing network. Red Hat (or another distro if it's better suited) would boot and run off the CD without needing any (or much) HD space. This way the computers aren't changed and I can have a virtual supercomputer for a while. Mmm 18Ghz. Anyway has anyone tried this before? Also I'd appreciate any suggestions on which distro to use and what cluster software/daemons I'd need. i.e. Beowolf or something like it." While an interesting approach to clustering, unless each node has quite a bit of RAM, I would think that you might need a marginal swap partition. What problems do you see with this idea, and would they be surmountable? Might such an idea be useful for quickly converting a computer lab to a cluster when it's not being used for other things?

MrZeebo writes "According to a story on Yahoo! News, Bush has finally decided to lift the Cold War-era restrictions on how fast an exported computer can be. Now, computers as fast as 195,000 MTOPS (up from 85,000 MTOPS) can be exported to countries such as Russia, China, and Pakistan."

Nate LaCourse writes: "Real good one from Cringely this month. It's on building his own supercomputer, but with some twists." You'll probably also want to check out the KLAT2 homepage to learn more about their Flat Neighborhood Network. And since KLAT2 has been around for nearly a year (check out the poster on this page!), perhaps a 3rd generation is in the works?

onyxcide writes: "Envision is running a quick article on a new national grid of computing resources called TeraGrid. Half a petabyte of disk storage, 40-gigabyte-per-second national optical backbone, and 13 teraflops of computing power will make up this monster. It will allow "lavish amounts of online data to be continually available for instantaneous analysis, data mining, and knowlege synthesis." There's another article in the same magazine here: Transforming Research with High-Performance Grid Computing" LighthouseJ adds some details: "C|Net's news.com has a story about a new Compaq supercomputer named Terascale. It uses 3,000 Alpha EV68 processors distributed over 750 servers using networking systems from Quadrics. They say it can perform as fast as 10,000 desktop PC's combined in one second. The massive computer will make it's official debut on Monday at the Supercomputing Center in Pittsburgh PA."

gtg010b writes: "According to USA Today, the U.S. government is considering a private network to be used for all government communications. This network would be "separate from the Internet to keep it safe from hackers or terrorists" according to Richard Clarke, the head of the president's "cyberspace security adviser." Whatever happened to government not being above the people?" Clarke is the guy who's been crying "cyber Pearl Harbor" for a few years; apparently if you cry wolf long enough you get promoted. His request (.doc format) is informative. I should point out that the U.S. military already has such a network (I'm not even going to ask why the Feds can't piggy-back on it), so GOVNET would be for critically-important government agencies like the Department of Agriculture to communicate.

SLiDERPiMP writes: "Yahoo! News is reporting that HP created an 'off-the-shelf' supercomputer, using 256 e-pc's (blech!). What they ended up with is the 'I-Cluster,' a Mandrake Linux-powered [Mandrake, baby ;) ] cluster of 225 PCs that has benchmarked its way into the list of the top 500 most powerful computers in the world. Go over there to check out the full article. It's a good read. Should I worry that practically anyone can now build a supercomputer? Speaking of which, anyone wanna loan me $210,000?" Clusters may be old hat nowadays, but the interesting thing about this one is the degreee of customization that HP and France's National Institute for Research in Computer Science did to each machine to make this cluster -- namely, none.

burbs writes "Big Blue's dominator is getting closer to being turned on. The Earth Simulator in Japan is, supposedly, the world's fastest parallel-processing supercomputer. Designed for the Earth's weather, the computer should be able to predict climate for the entire planet for thousands of years in a short amount of time."

yoshi writes "Apparently, Lawrence Livermore Lab had an open house yesterday for ASCI White, the world's most powerful computer, and CNN has a story on it, including a picture of one of the sys admins! One of the great things about the system is how much information is available. Check out the hardware and software environments."

zoombat writes "The BBC reported that the Cray SV1 product line won the Readers' Choice Award for Best Supercomputer for 2001 by the readers of Scientific Computing & Instrumentation magazine. These beasts have some pretty remarkable stats, including a 300 Mhz CPU clock, up to 192 4.8 GFLOPS CPUs or 1229 1.2 GFLOPS CPUs, and up to a terabyte of memory. And they sure know how to paint 'em real nice. Of course, we all know how "scientific" the Readers' Choice Awards are..."

Troy Baer writes: "SGI and the Ohio Supercomputer Center (OSC) have announced the installation of the first cluster using Itanium processors. The system consists of 73 SGI 750 nodes, each with two Itanium 733MHz procs and 4GB of memory, connected by Myrinet 2000 and Ethernet. Software includes Linux/ia64, SGI's ia64 compiler suite, MPICH/ch_gm, OpenPBS, and Maui Scheduler."

dev_null_ziggy writes: "CNN reports that the current chess guru is going up against a supercomputer, amusingly titled 'Deep Fritz.' The match is scheduled for October, and the current champion, Vladimir Kramnik, stands to win $1 Million dollars if he wins. Of course, since he'll be snagging $800k for a draw, and $600k for a loss ... I'll give two to one odds on the machine."

D Anderson n'Swaart writes: "BBC News is reporting that a recent experiment called Project Boomerang, conducted with a super-sensitive telescope suspended 40 km above Antarctica, has provided powerful new evidence to support the current trend in scientific thinking that the fabric of space is essentially flat, and not curved as Einstein postulated. The one billion measurements gathered took three weeks to analyse on a Cray T3E supercomputer, and have provided insights on the creation of the universe, and suggest that it will continue to expand indefinitely without collapsing in a Big Crunch."

SEWilco writes "Sandia National Laboratories has released its "Cplant" massively parallel processing software. This is related to the software used in their ASCI Red supercomputer, and eliminates several scalability problems to allow hundreds of nodes for algorithms which can't be parallelized for Beowulf-type clusters. This is now number 2 on the TOP500 supercomputer list. The press release refers to "licensing terms", but the license is the GPL. We discussed this in a Linux clusters discussion and several earlier reports as ASCI Red grew."

Jay Carlson writes "We've all heard about how Apple's hardware is really fast compared to PCs. ("Supercomputer!" "Twice as fast as a Pentium!" "Most powerful laptop on the planet!") So, if you *aren't* going to use Photoshop and Final Cut Pro, how fast is it? I care more about integer apps like compilers, so I did some careful benchmarking of a few x86 and PPC Linux boxes. Submissions welcome."

Random Walk writes "A group of researchers from the UCSD Supercomputer Center has used a technique they call "backscatter analysis" to study the prevalence and targets of DoS attacks. They claim that their study is "the only publically available data quantifying denial-of-service activity in the Internet", and provide interesting statistics on attack rates, durations, and victims."
