With IBM having recently announced it was building a supercomputer with 1.6 million cores capable of 20 petaflops of computing power, its hard to get too jazzed over a single petaflop. But for Europe, breaking the petaflop barrier is something that hasn't been done, but soon will be.
IBM and German research center Forschungszentrum Juelich are collaborating to build a new Blue Gene/P System supercomputer for Europe. It will mark the first time that a supercomputer capable of delivering petaflops of performance will be located outside of the U.S.
"With speeds over a Petaflop, this new Juelich-based supercomputer offers the processing ability of more than 200,000 laptop computers," explains Professor Thomas Lippert, lead scientist of the Juelich supercomputing center. "In addition to raw power, this new system will be among the most energy efficient in the world."
The Blue Gene/P System will house 294,912 processor, 144TB of memory, and 6PB of hard drive storage contained within 72 server racks. Adding to the historical significance, it will also be IBM's first watercooled supercomputer. IBM says the use of watercooling will result in a 91 percent reduction in air conditioning units that otherwise would have been required to cool the data center.
Some people harness the awesome power of Google Earth to view distant lands they may never reach, take in a crime in progress, or maybe even find a 3 billion dollar shipwreck. At least that’s the claim of Nathan Smith, a Los Angeles musician who appears to have spotted the remains of a Spanish barquentine while zooming in on a shoeprint shaped object in the Aransas Pass in Texas. This assumption was based on historical records which put a lost barquentine (three massed sailboat) near that location south of Refugio, Texas, in 1822.
After consulting with a few experts, he traveled to the location which just happens to be the private ranch of the late Morgan Dunn O’Connor. The result of this drama will end up being decided in the courts with the family of Mr. O’Connor and Mr. Smith in a bitter dispute over salvage rights. If the courts determine that the land is located within a navigateable waterway, the first person to find the wreck is entitled to the spoils, otherwise the bounty goes to the O’Connor family.
As if this wasn’t complicated enough, the state of Texas is also considering its options because it disputes the existence of a commercial waterway near the wrecks location. If this is proven true, the state might have found a surefire way to balance its books come budget time. U.S. District Judge David Hittner will rule on the salvage rights within two months time.
When you consider the complexity of modern day web pages, it’s actually a bit of a miracle that search engines work as well as they do. Dealing with duplicate links, especially off pages such as Amazon that may promote an individual product a thousand times or more has always been a challenge. Finally, after years of debate, Google, Yahoo and Microsoft are putting the past behind them to solve this age old issue. The solution is a simple tag that will be added to the standard link format called “canonical”.
The tag is designed to solve issues associated with multiple URL’s pointing to the same page, but may also be helpful when multiple versions of a page exist. Currently, the search engines employ a process that looks at the structure of URL’s to look for similarities. This generally works pretty well, but is far from perfect. It is considered to be somewhat rare for search engines to come together on any issue, but it isn’t unprecedented. In 2006 they joined forces to put unanimous support behind sitemaps.org, and in June of 2008 they jointly announced new standards for the robots.txt directive. Matt Cutts of Google and Nathan Buggia of Microsoft claim this new approach should help reduce the clutter on the web, and improve the accuracy of all search engines.
Even though these tags won’t completely solve all the duplicate problems found on the web, it should significantly enhance the indexing performance of search engines, particularly on e-commerce sites. The new tags will be discussed in depth at this year’s Ask the Search Engines panel at SMX West.
Gigabit Ethernet may still outrun all but the most extreme SSD Raid configurations, but researchers can never rest on their laurels. Always hoping to invent the next big thing, scientists now have their sights set on Terabit Ethernet to help quell our insatiable hunger for bandwidth. A team from Australia, Denmark, and China has combined their efforts to demonstrate terabit-per-second speeds using fiber optic cables, laser light, and an unusual material named chalcogenide.
The group documented the results of its most recent trial in a white paper published in the February 16th 2009 issue of Optics Express. Though the technology is promising, Ben Eggleton, research director for CUDOS (Center for Ultrahigh bandwidth Devices for Optical Systems), points out the current limitations. “The problem isn't injecting that much high speed data into an optical strand, called multiplexing, but retrieving data at such high rates”. Conventional electronics are capable of injecting dozens of 10 Gbps streams, but trying to retrieve these streams any faster than 40 Gbps is beyond our current capabilities.
The breakthrough here however isn’t in the speed itself, but in proving the concept.Until the processing hardware catches up with our transmission capabilities, you won’t be finding this in routers anytime soon. Eggleton speculates that these concepts can be adapted to achieve slower and more manageable results, but the goal of this experiment was simply to prove that it was possible using fully photonic chips built using the same methods employed by current CMOS circuits. "It's years to complete," Eggleton said, taking these research efforts into a production technology. But these demonstrations "are starting to establish this is a serious proposition."
It is a disgrace that humans haven’t still got the hang of setting passwords. It seems as though that most internet users have inextricably tethered themselves to a promise of not setting strong-enough passwords, which may force hackers to reconsider their choice of profession for its grueling nature. As you devour more of this story, you will begin to envy hackers for having it stroll-in-the-park easy.
A new study has revealed – rather reiterated - that internet users nonchalantly continue to set unimaginative, fatuous passwords. The study appraised 28,000 passwords that were recently stolen from a U.S website.
Sixteen percent of the users had set their first name as their password. Around fourteen percent chose easiest to recall key combinations, including “1234” and “12345678”. Other users, who apparently don’t rate their mathematical ability highly, chose to steer clear of numbers and settled for passwords such as “AZERTY” and “QWERTY”.
Five percent of the passwords were found to be inspired by popular things and celebrities, including names of movies, TV shows and actors. The strongest password in this category was found to be “Ironman” as it sounds impenetrable.
Three percent of the people reckon passwords are another medium of expression. How else would you explain passwords like “Iloveyou” and “Ihateyou?”
Downloading Youtube videos has been a piece of cake for quite sometime now, though Youtube never expressly gave its assent to downloading until last month, when it made it possible for users to download videos from Barack Obama’s Youtube channel. As it turns out now, the company was just testing waters by allowing Obama’s videos to be downloaded.
Now, the video sharing website has formally approved downloading. Not all videos will be free to download, however, as users will have to pay a fee to download some of the videos. Youtube is testing an option that will let video publishers make their content available offline for free or for a price they deem fit. All payments will be processed by Youtube’s cognate company Google Checkout.
It is strange that Youtube expects users will actually be interested in paying for videos when they can be download for free through the large number of online tools available for that purpose.

Sony Music Entertainment became the first of the four largest recording companies to renew their music licensing deal with YouTube.
The renewal has ensured that Sony artists will remain on the video-sharing site exclusively. Deals such as this allow YouTube users to not only view the artist’s music videos, but to also use the label’s songs in their clips.
It’s been reported that Universal Music Group is close to breaking a deal with YouTube, and if they signed it would leave only EMI and Warner Music Group. Though, talk between EMI and YouTube ran into some trouble last month, and since then their content has been removed from the site.
