Universe is Flat 41

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."

"Cplant" Parallel Computing Tool 77

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."

x86 vs PPC Linux benchmarks 269

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."

Study on DoS Activity In The Internet 53

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." CT:This is an amazing report.

Hash Cash 15

km790816 writes: "I was reading an article in US News about a novel way to end spam: Hash Cash. From US News: 'our E-mail systems could be configured to reject every message from a stranger until the sender's computer had performed a difficult math problem and sent back the correct result. For one-to-one correspondence, this preliminary step would be unnoticed. But bulk E-mailings to strangers would become too costly in terms of needed computational cycles to be feasible, even with a supercomputer.'" If you've heard of Hash Cash before, don't click through, there's nothing new here. But if you haven't, here's a good introduction to the concept.

Clay Shirky Defends P2P 113

richard writes: "Clay Shirky has responded to Jon Katz's article, Does P2P Suck?, (and a WSJ article published the same day) in an article titled "Backlash!" on OpenP2P.com. Shirky says: "P2P means many things to many people. PC users don't have to be second-class citizens. PCs can be woven directly into the Internet. Content can be provided from the edges of the network just as surely as from the center. Millions of small computers can be more reliable than one giant server. Millions of small CPUs can do the work of a supercomputer. ... These are sloppy ideas, ideas that don't describe a technology or a business model, but they are also big ideas, and they are also good ideas.""

New Supercomputer By Star Bridge 58

Ronin Developer writes with word of this "interesting article on CNN about a new desktop-size super computer that reconfigures itself on the fly. The company name is 'Star Bridge.' Ring any bells? If I remember correctly, wasn't there something on /. about this a year ago?" Indeedy do -- Star Bridge seems to go straight from wacky-but-cool promises to Where are they now? (and back) with finesse. It's the the Arnold Schwarzenegger movie plot of hardware companies -- simultaneously head-scratchingly implausible, mildly compelling, and numbingly persistent.

Update From Cray World 108

rchatterjee writes "Cray, the only mainstream recognizeable name in supercomputing, has been busy lately. Their totally new MTA-2 supercomputer design will use a UltraSPARC-III powered Sun Fire 6800 server to just feed the data to the MTA-2's processor. They're also refocussing on Vector Supercomputers and are going to release their first new vector supercomputer since Tera Computing bought them, the SV-2 in 2002. And if that wasn't enough they have a deal with API networks to develop Alpha processor based Beowulf clusters of Linux machines that as a cluster will run the same operating system as Cray's T3E supercomputers. Seymour Cray would be proud. You can get a quick overview of all the latest Cray developments from this article on Cnet."

Sony, IBM and Toshiba are joining toether to create a 'supercomputer on a chip' which sounds like the PS3 will be much more than just another games console.

How Many Boxes In A Decent Beowulf Cluster? 18

Rick the Red asks: "I'd like to build a mini-supercomputer for our High School (and perhaps another for the Junior High). Given that cost is an issue, but given that effective, hands-on demonstration of the principles of parallel processing and clustered computing is the primary goal, how many nodes would it take to make a reasonable demonstration Beowulf cluster? Two? Eight? Sixteen? Has anyone else here done this, and if so are there resources (lesson plans would be nice) on the net for teachers? Also, has anyone networked a room full of computers such that one minute they're individual PCs available for the usual classroom stuff and the next minute they're a Beowulf cluster? If so, how did you do it? And for the final, far out question: Has anyone ever used VMware to create a Beowulf simulator, clustering virtual PCs running on one physical box?"

Juno And Privacy 198

Karl Weiss writes: "Section 2.5 of the Juno Privacy Policy has some very interesting statements in it - you authorize them to download an app to track your usage and you can't do anything about it, you are to keep your computer on 24/7, or give them the right to make your computer call out at their desire, and they can install a screen saver on your computer with ads, and you can't get rid of it. Obviously this bothers me, but the real kicker as far as I'm concerned is that they will allow third parties to use the downloaded software. Does M$ looking for pirated software sound like a player? Or what happens if someone cracks the software? Does that open your hard drive data to anyone? As the senior network instructor at a large private computer school, I have advised faculity and staff to not use Juno due to these requirments." It looks like the few remaining free ISPs are searching for ways to make up advertising income during the dot-com meltdown, and the "solution" they've come up with is to make use of their users' computers to do distributed processing. Will Juno users realize what they are agreeing to?

Beowulf For Dummies? 122

The people behind it are Oak Ridge National Labs and the National Center for Supercomputing Applications and some private companies. According to this Newsforge (part of the Keiretsu) story their 'Supercomputer on a CD' software is supposed to make it so easy to put a Beowulf cluster together a high school student or MCSE can do it in a few hours."
