Leibniz?s ?SuperMUC? named Europe?s fastest supercomputer

The Leibniz Supercomputing Centre (LRZ), in collaboration with IBM (NYSE: IBM), today announced the world?s first commercially available hot-water cooled supercomputer, a powerful, high-performance system designed to help researchers and industrial institutions across Europe investigate and solve some of the world?s most daunting scientific challenges.

Timeline: IBM?s History and Future in Water Cooled Computing (1966-2060)

The new LRZ ?SuperMUC? system was built with IBM System x iDataPlex Direct Water Cooled dx360 M4 servers with more than 150,000 cores to provide a peak performance of up to three petaflops, which is equivalent to the work of more than 110,000 personal computers. Put another way, three billion people using a pocket calculator would have to perform one million operations per second each to reach equivalent SuperMUC performance. Also, a revolutionary new form of hot-water cooling technology invented by IBM allows the system to be built 10 times more compact and substantially improve its peak performance while consuming 40 percent less energy than a comparable air-cooled machine.

?This year all the electricity consumed by state-funded institutions across Germany are required to purchase 100% sustainable energy,? said Prof. Dr. Arndt Bode, Chairman of the Board, Leibniz Supercomputing Centre. ?SuperMUC will help us keep our commitment, while giving the scientific community a best-in-class system to test theories, design experiments and predict outcomes as never before.?

Pioneering Hot-Water Cooled Technology

Up to 50 percent of an average air-cooled data center?s energy consumption and carbon footprint today is not caused by computing, but by powering the necessary cooling systems. IBM scientists and developers chose to address this challenge with an innovative concept of hot-water cooling, which eliminates the need for conventional data center air cooling systems. IBM?s hot-water cooling technology directly cools active components in the system such as processors and memory modules with coolant temperatures that can reach as high as 113 degrees Fahrenheit, or 45 degrees Celsius.

?As we continue to deliver on our long-term vision of a zero emission data center we may eventually achieve a million fold reduction in the size of SuperMUC, so that it can be reduced to the size of a desktop computer with a much higher efficiency than today,? said Dr. Bruno Michel, manager, Advanced Thermal Packaging, IBM Research.

SuperMUC combines its hot-water cooling capability, which removes heat 4,000 times more efficiently than air, with 18,000 energy-efficient Intel Xeon processors. In addition to helping with scientific discovery, the integration of hot-water cooling and IBM application-oriented, dynamic systems management software, allows energy to be captured and reused to heat the buildings during the Winter on the sprawling Leibniz Supercomputing Centre campus, for savings of one million Euros ($1.25 million USD) per year.

Europe?s Most Powerful Supercomputer

The SuperMUC system is Europe?s fastest computer, according to the TOP500 list of the world?s fastest supercomputers announced today. This performance will be used to drive a wide spectrum of research ? from simulating the blood flow behind an artificial heart valve, to devise quieter airplanes to unearthing new insights in geophysics, including the understanding of earthquakes. The SuperMUC system is also connected to powerful visualization systems, including a large 4K stereoscopic power wall and a five-sided immersive artificial virtual-reality environment or CAVE for visualizing 3D data sets from fields, including Earth science, astronomy and medicine.

The LRZ is the computer center for Munich?s universities and for the Bavarian Academy of Sciences and Humanities. It takes care of the scientific data network in Munich, offers a variety of data services, and provides high-end computing facilities for the scientific community across Europe.

The center?s new SuperMUC system is the largest in Europe and one of the most powerful systems in the world. It is part of the Partnership for Advanced Computing in Europe (PRACE) high-performance computing infrastructure for researchers and industrial institutions throughout Europe. The supercomputer is jointly funded by the German federal government and the state of Bavaria. It will be officially inaugurated in July 2012 at Leibniz Supercomputing Centre in Garching, Germany.

SNES-001 Advance gives two retro gamers a screen to play, guarantees no fights for TV time (video)

There's been no shortage of SNES mods with built-in screens. They almost always tend to overlook one fundamental problem, however: with only one screen, gamers have to either share one tiny LCD or play solo, and neither option will make that Street Fighter II nostalgia trip a pleasant one. Frequent console modder Downing has offered a fix with a key trade-off. Although his Super Famicom-like SNES-001 Advance is decidedly non-portable, each gamepad has its own LCD to show what would normally go to one screen, even with audio. Both controllers are custom-molded creations that still plug in the old-fashioned, wired way. Downing certainly isn't hoarding his creation, despite it being one of a kind. An auction for the console (with a $500 buy-now price) is still well underway as of this writing, making sure that at least two Double Dragon fans will be happy without cutting into their less sentimental roommate's Netflix marathon.

Analysis: Facebook stock's bad start reins in short sellers

NEW YORK (Reuters) - Facebook's weak stock market debut has a potential silver lining for the social media giant - some short sellers may have been scared off.

About 8.1 percent of the 421 million shares in the initial public offering were sold short as of May 31, about two weeks after its trading debut, according to a Reuters analysis of exchange data.

That percentage is lower than for Pandora Media Inc, LinkedIn Corp, Angie's List Inc and Groupon Inc - half of the other Internet companies that went public in the past year. And Google Inc, with which Facebook is often compared, attracted a much higher short interest in the first couple of weeks after its IPO in 2004.

Short sellers borrow stock and then sell it, betting that it will decline in value and that they can then buy it back more cheaply.

Facebook had a tough first few weeks of trading. Its debut was marred by technical glitches on Nasdaq and reports that analysts at top underwriters reduced their revenue and earnings forecasts only days before the offering. Its shares rose only 23 cents on opening day and in subsequent days fell as low as $25.52, 33 percent below the $38 offer price.

But short sellers, after initially sensing a chance to profit from negative market sentiment and Facebook's rich valuation, may have backed off as the shares plunged.

"The opportunity to make money on short selling is greatest when a stock is overvalued," said Jay Ritter, a University of Florida IPO expert who reviewed Reuters' analysis. When the price falls, it signals "time to take profits" because "the possibility of a further decline becomes smaller."

Among the companies that were more heavily shorted, LinkedIn's shares soared as much as 173 percent above their offer price on their first day; Groupon, 56 percent; Pandora Media, 62 percent; and Angie's List, 44 percent.

Facebook's stock price gain in the first few minutes of trading was limited to 18 percent before the decline set in.

DOESN'T MAKE SENSE

Steve Spencer began shorting Facebook at $32 per share the Tuesday after the public offering, but has since stopped. Indeed, Facebook's shares have recovered in the past two weeks to trade around $32 on Tuesday.

"The risk/reward doesn't make sense to me right now," said Spencer, who co-heads SMB Capital, a proprietary trading shop in New York. "If people wanted to make a bet on the short side, they were doing it in the mid-30s."

To be sure, in terms of the raw number of shares shorted, Facebook's initial short bets in the first two weeks of trading are bigger than those of any Internet company listing in the past year.

More than 34 million shares were sold short as of May 31, the latest date for which the data is available. But the figure is not surprising, given the size of Facebook's offering.

Some small investors have kept their Facebook shares, hoping they will bounce back.

"I didn't think it would do this badly," said Tony Allen, a Detroit real estate entrepreneur who bought 50 shares on the day of the offering at $42 and has watched his investment sink in value. He said he was holding on in the hopes of a "turnaround."

A Facebook spokesman declined to comment.

SHORTING COST SOARS

Initially, short sellers' demand for Facebook shares was so high it forced another barometer of bearish investor activity to skyrocket. The annual interest rate charged on the value of borrowed Facebook shares soared to more than 40 percent initially, said David Lewis, senior vice president at Astec Analytics, which tracks stock borrowing costs.

"Anything over 1 percent you consider to be quite special, and this was 40 percent," Lewis said. The interest rate has fallen quickly since and is now at around 0.6 percent, indicating a lot more stock is available for borrowing.

Reuters gauged the degree of shorting activity for stock listings similar to Facebook by calculating the percentage of their publicly listed shares that had been sold short following their IPO. Reuters' data comes from the stock exchanges, which publish short interest reports every two weeks, or for older listings, every month. Reports closest to IPO date were used for the analysis.

It is unclear what the short interest says about the stock's long-term prospects. "Outside of IPOs, almost all of the research indicates that short selling is a negative signal," said Ben Blau, a finance professor at Utah State University.

But IPOs are harder to call. Not every company that attracts a high degree of bearish investor sentiment ends up performing poorly.

For example, search engine Google attracted short bets that amounted to about 21 percent of its publicly listed shares shortly after its August 2004 offering - nearly triple that of Facebook. Yet from the beginning, Google defied the shorts: Priced at $85, its shares opened at $100, doubled by January 2005 and closed above $300 six months later - a level they have rarely breached since then. Google's stock was trading on Tuesday at around $582.

During the dotcom boom in the late 1990s, many stocks had higher early short interest levels than Facebook. They include companies that went on to thrive, like eBay Inc, as well as some that collapsed, such as Pets.com.

BORROWING INCREASE

The latest data from Astec opens up the possibility that short investors may have increased their negative bets on Facebook.

Astec estimates there are currently about 52.1 million Facebook shares on loan. That is up from 34.3 million on May 31, about the same as the shares reported short as of that date. If most of the shares now on loan are again shorted, it would indicate that Facebook's short interest could be as high as 12.4 percent.

North Wales News: Energy minister ?positive? about Wylfa B

NUCLEAR cash will pay to boost the economic fortunes of Anglesey while the Energy Minister told workers he remained ?positive? that Wylfa B will happen.

In March RWE and E.on scrapped their ?8bn investment plans for Wylfa B sparking fears the planned 5,000 construction jobs and up to 1,000 permanent roles would never materialise.

Since then the German power giants have been seeking a new buyer with support from the Welsh and UK Governments.

Yesterday Energy minister Charles Hendry arrived on the island to speak to nuclear workers at Wylfa and announce a new ?480,000 funding package for the Anglesey Energy Island Programme (EIP).

This money from the Nuclear Decommissioning Authority will train up young people for energy sector jobs, support inward investment and supply chain opportunities, and help pay for energy related infrastructure.

On Wylfa B, he told the Daily Post: ?We are very positive about new buyers being found for a new nuclear plant on Anglesey.

?There have been significant expressions of interest in the site, which is an exceptional site.

?I told workers that I understood their disappointment at the withdrawal of the RWE and E.on but assured them that the Government was doing all it could to encourage new investment.?

He added: ?The new funding will enable the Council to invest in education, skills, and infrastructure, and boost the local economy. These will allow young people to go for the jobs of the future.?

During his day-long visit to Anglesey Mr Hendry also addressed students at Coleg Menai?s Energy Centre and met officials from the Energy Island Programme, Horizon Nuclear Power, Magnox Limited and EnergySolutions.

Anglesey council leader cllr Bryan Owen said: ?It?s fitting that the Energy Minister should make his statement here on Anglesey as ? in Wylfa ? we have one of the best new nuclear build sites in Europe. I?m also delighted to hear about the new NDA funding which will allow us to develop a number of key EIP work streams.?

Cllr Owen added: ?During his visit, the Minister saw first hand the many positives Anglesey has to offer in relation to new nuclear build ? both in terms of the excellent skills set which already exists amongst the Wylfa workforce and how we?re investing in our young people through Coleg Menai?s Energy Centre, which provides training that will help them find work in future major energy developments.?

NDA Director of Stakeholder Relations, Jon Phillips, added: ?The Energy Island Programme has delivered excellent progress over the past three years and we are delighted to maintain our support with this latest grant, which we hope will make an important contribution to unlocking future economic activity and to building a sustainable future for Anglesey.?
