Indian origin scientist’s supercomputer can perform 28.16 trillion calculations per second

Washington, August 22 (ANI): A scientist of Indian origin has created a new supercomputer, called Cystorm, which can carry out 28.16 trillion calculations per second.

Cystorm, a Sun Microsystems machine, was developed by Srinivas Aluru from the Iowa State University.

The 3,200 computer processor cores that power Cystorm makes it perform 28.16 trillion calculations per second, which is five times the peak of CyBlue, an IBM Blue Gene/L supercomputer that’s been on campus since early 2006 and uses 2,048 processors to do 5.7 trillion calculations per second.

According to Aluru, the Ross Martin Mehl and Marylyne Munas Mehl Professor of Computer Engineering and the leader of the Cystorm project, the new machine also scores high on a more realistic test of a supercomputer’s actual performance: 15.44 trillion calculations per second compared to CyBlue’s 4.7 trillion per second.

That measure makes Cystorm 3.3 times more powerful than CyBlue.

“Cystorm is going to be very good for data-intensive research projects,” Aluru said. “The capabilities of Cystorm will help Iowa State researchers do new, pioneering research in their fields,” he added.

The supercomputer is targeted for work in materials science, power systems and systems biology.

Aluru said that materials scientists will use the supercomputer to analyze data from the university’s Local Electrode Atom Probe microscope, an instrument that can gather data and produce images at the atomic scale of billionths of a meter.

Systems biologists will use the supercomputer to build gene networks that will help researchers understand how thousands of genes interact with each other.

Power systems researchers will use the supercomputer to study the security, reliability and efficiency of the energy infrastructure of the US.

Computer engineers will use the supercomputer to build a software infrastructure that helps users make decisions by identifying relevant information sources.

“These research efforts will lead to significant advances in the penetration of high performance computing technology,” said a summary of the Cystorm project. (ANI)

Quantum computers come closer to reality (Re-Issue)

Washington, July 1 (ANI): A team led by Yale University researchers has created the first rudimentary solid-state quantum processor, taking another step toward the ultimate dream of building a quantum computer.

They also used the two-qubit superconducting chip to successfully run elementary algorithms, such as a simple search, demonstrating quantum information processing with a solid-state device for the first time.

“Our processor can perform only a few very simple quantum tasks, which have been demonstrated before with single nuclei, atoms and photons,” said Robert Schoelkopf, the William A. Norton Professor of Applied Physics and Physics at Yale.

“But this is the first time they’ve been possible in an all-electronic device that looks and feels much more like a regular microprocessor,” he added.

Working with a group of theoretical physicists led by Steven Girvin, the Eugene Higgins Professor of Physics and Applied Physics, the team manufactured two artificial atoms, or qubits (“quantum bits”).

While each qubit is actually made up of a billion aluminum atoms, it acts like a single atom that can occupy two different energy states.

These states are akin to the “1″ and “0″ or “on” and “off” states of regular bits employed by conventional computers.

Because of the counterintuitive laws of quantum mechanics, however, scientists can effectively place qubits in a “superposition” of multiple states at the same time, allowing for greater information storage and processing power.

These sorts of computations, though simple, have not been possible using solid-state qubits until now in part because scientists could not get the qubits to last long enough.

While the first qubits of a decade ago were able to maintain specific quantum states for about a nanosecond, Schoelkopf and his team are now able to maintain theirs for a microsecond-a thousand times longer, which is enough to run the simple algorithms.

To perform their operations, the qubits communicate with one another using a “quantum bus”-photons that transmit information through wires connecting the qubits-previously developed by the Yale group.

“The key that made the two-qubit processor possible was getting the qubits to switch “on” and “off” abruptly, so that they exchanged information quickly and only when the researchers wanted them to,” said Leonardo DiCarlo, a postdoctoral associate in applied physics at Yale’s School of Engineering and Applied Science and lead author of the research paper.

Next, the team will work to connect more qubits to the quantum bus.

“The processing power increases exponentially with each qubit added, so the potential for more advanced quantum computing is enormous,” Schoelkopf said. (ANI)

Conversing helps kids better develop language skills than reading

Washington, June 30 (ANI): Having conversations with your children could help them develop language skills, according to a new study.

The study by UCLA researchers has found that adult-child conversations have a more significant impact on language development than exposing children to language through one-on-one reading alone.

“Paediatricians and others have encouraged parents to provide language input through reading, storytelling and simple narration of daily events,” explains study’s lead author, Dr. Frederick J. Zimmerman, associate professor in the Department of Health Services in the UCLA School of Public Health.

“Although sound advice, this form of input may not place enough emphasis on children’s role in language-based exchanges and the importance of getting children to speak as much as possible,” Zimmerman added.

The study of 275 families of children ages 0-4 was designed to test factors that contribute to language development of infants and toddlers.

Participants’ exposure to adult speech, child speech and television was measured using a small digital language recorder or processor known as the LENA System.

This innovative technology allowed researchers to hear what was truly going on in a child’s language environment, facilitating access to valuable new insights.

The study found that back-and-forth conversation was strongly associated with future improvements in the child’s language score.

Conversely, adult monologueing, such as monologic reading, was more weakly associated with language development. TV viewing had no effect on language development, positive or negative.

“What’s new here is the finding that the effect of adult-child conversations was roughly six times as potent at fostering good language development as adult speech input alone,” Zimmerman said.

The study has been published in the July issue of Paediatrics, the journal of the American Academy of Paediatrics. (ANI)

Online Merchants now easily accept the world’s popular non-credit-card

Mumbai, May 30 (ANI/Business Wire India): PayByCash(r), a subsidiary of PlaySpanT, today announced the availability of the PayByCash CodeT, the most accessible pre-paid product for consumers in 180 countries. PayByCash’s revolutionary new product provides consumers with a streamlined way to make Internet purchases.

Using a PayByCash Code is similar to using a credit-card but without the activation hassles that make store-purchased prepaid cards challenging for many consumer demographics.

“The great benefit for online retailers is that they can now effortlessly tap into a huge new pool of consumers who previously were unable to complete online purchases,” said Kevin Higgins, President of PayByCash. “We’ve removed the need for merchants to modify their ecommerce systems in order to accept various countries’ popular payment methods, especially those used by credit-constrained or unbanked consumers.” “Furthermore, with the ongoing credit crunch, PayByCash Codes enable merchants to remain accessible to consumers who are losing access to their credit cards.”

Higgins continued, “This program is revolutionary in that it bundles PayByCash’s unrivaled international payment processing capability, its online experience, and the convenience of a credit-card checkout, with acceptance that’s so easy that many merchants could literally begin accepting PayByCash Codes in less than a day. That means a potential immediate revenue lift of 5 to15% or more with almost zero effort.”

An enormous number of consumers who don’t use credit cards because they are unbanked or live in the many countries where cash payment methods remain highly popular can now enjoy the value and convenience of international Internet shopping. In addition, this means online merchants have just been given easy access to the hugely lucrative but tough-to-reach global teen and college demographics.

It also means merchants can safely accept PayByCash Codes from parts of the world where they would normally decline a conventional credit card transaction due to the risk of payment fraud. With this product’s unveiling, PayByCash becomes the first processor to provide access to the world’s most popular non-bank-based payment methods to merchants whose systems only accept major credit cards.

According to a recent New York Times article, “Every major credit card issuer has been approving fewer new applicants, reining in credit lines and canceling unused accounts. And Meredith A. Whitney, a prominent banking analyst, expects credit card lenders to cut the lines of credit they extend to borrowers by a total of $2.7 trillion through 2010.

That is equivalent to a 57 percent reduction in the credit they made available two years ago at the height of the boom.” PayByCash Codes make these and the estimated more than a billion people globally who lack bank accounts or who don’t have access to credit cards more accessible to online merchants.

Humans ‘can’t distinguish pate from dog food’

Washington, May 2 (ANI): People might one day be eating dog food, for a new study has found that it tastes as good as liverwurst or duck liver mousse.

The researchers found that people can’t differentiate in the flavour of dog foods with that of normal human foods.

In the study involving 18 subjects, the research team separately put organic Canned Turkey and Chicken Formula for Puppies/Active Dogs, duck liver mousse, pork liver pâté, liverwurst, and spam in a food processor.

Pâté is a mixture of minced meat and fat in the form of spreadable paste, generally made from a finely ground or chunky mixture of meats and liver, and often with additional fat, vegetables, herbs, spices or wine.

The resulting product was put into five different bowls and garnished with parsley.

They found that although the volunteers didn’t exactly prefer the dog food, they couldn’t identify it either.

“Only 3 of 18 subjects correctly identified sample C as the dog food,” CBS News quoted the paper as stating.

“Although human beings do not enjoy eating dog food, they are also not able to distinguish its flavour profile from other meat-based products that are intended for human consumption,” the authors added. (ANI)

Now, ultra small, energy efficient computer chip

Washington, Apr 23 (ANI): Scientists from University of California, Davis have developed an ultra small chip that provides breakthrough speeds for a variety of computing tasks.

The 167-processor chip, known as AsAP, is fully reprogrammable, extremely energy-efficient, highly configurable. It can be widely adapted to a number of applications.

The maximum clock speed for the 167-processor AsAP is 1.2 gigahertz (GHz), but at slower speeds its energy efficiency soars.

Moreover, twelve chips working together could perform more than half-a-trillion operations per second (.52 Tera-ops/sec) while using less power than a 7-watt light bulb.

“A battery powering this chip will typically last from several times to 75 times longer than it would under the same workload when powering some of the common commercially available digital signal processing chips,” said Bevan Baas, associate professor of electrical and computer engineering and leader of the design team.

“At the same time, with our targeted applications, we’re getting several times to 10 times better speed than what is currently available – all with a much smaller chip.

“To the best of our knowledge, this is the highest clock-rate processor chip designed at any university,” Baas added.

The chip, built with industry-standard fabrication technology and design tools, embodies a number of novel architectural and circuit features, Baas explained.

The scientists have written a number of software applications for the chip, which has been fabricated by the international electronics company STMicrotronics. Some of them are Wi-Fi receiver and several complex components of an H.264 video encoder.

The details of the design have been published in IEEE Journal of Solid-State Circuits. (ANI)

Microsoft rolls out India-specific gaming console – Xbox 360 Arcade

Rolling out its new entry-level gaming console Xbox 360 Arcade in India, Microsoft intends substituting it with the Xbox 360 Core model. The new console offers five interesting Zbox LIVE Arcade games – Uno, Luxor 2, Boom Boom Rocket, Feeding Frenzy, and Pac-man Championship Edition.

According to a statement released by the company, the new console will change the entire gaming spectrum, with its HDMI output to enable users experience the games in the highest-possible definition – up to 1080p, with the HDMI cable and network cable to be sold separately. The console also comes packed with a wireless controller.

Microsoft’s Xbox 360 Arcade is apparently an endeavor to bring forth a reasonably-priced version of the popular console for India. An upgraded model of the Xbox 360 version, the new console – which is largely designed for first-time users of gaming consoles – comes fitted with IBM PowerPC 3 core 3.2GHz processor and 512MB GDDR3 video memory.

The newly-launched India-specific Xbox console also comes with a number of entertainment features, including viewing photos, movies and music – it augments photos, video, music and TV; facilitating sharing of digital pictures and streaming of digital media. Furthermore, it provides its users with other online console gaming pitch such as downloadable high-definition and standard-definition content!

Extensions add new functions to OpenOffice

Kaufbeuren, Germany – The basic version of the free office software suite, OpenOffice, packs in a lot of functionality. Yet for some users it’s just not enough. Fortunately it doesn’t need to be. A variety of extensions, most available for free, can be used to add even more pep to the standard version. This type of modular software construction is familiar to users of web browsers like Firefox and Opera as an effective way to integrate expanded capabilities. As with OpenOffice itself, these are free software add-ons developed by enthusiastic developers from the OpenOffice community.

“The spectrum of extensions ranges from tweaks to small details up to extensive expansions of the core functionality,” says Florian Effenberger, spokesman for the OpenOffice. org project.

The central English-language repository is available at http://extensions.services.openoffice.org and includes roughly 300 extensions. Yet, not all extensions are indexed there. Effenberger presumes that hundreds more of the little utilities are out there as well.

One popular type of extension is document templates. Another is PDF Import Extension, which enables users to edit PDF files. While the basic version of OpenOffice can open files of that kind, it can’t work edits back into the original very effectively. Also, adjusting the size of columns and rows in the Calc spreadsheet software can be tiring. CalcEasyToolbar makes it easier.

Presenter Console is a potentially useful aid for users who frequently create presentations in the OpenOffice module Impress. It provides a preview of the new slide, but only on the speaker’s monitor. Presentations with heavy multimedia content can be put on a diet using Presentation Minimizer. The extension makes presentations easier to open and e-mail.

If the user encounters an unknown term, Wikipedia can frequently provide quick assistance. The OOoWikipedia allows users to query the free encyclopedia from within the software directly. Anyone looking to create a Wikipedia article themselves can benefit from Wiki Publisher: a Wizard helps prepare articles composed in OpenOffice’s word processor Writer for publication on the Web. Along similar lines, the Weblog Publisher makes it easy to compose blog entries.

The extensions are easy to install. One option is to double click the already downloaded extensions with the file ending .”oxt.” The on-screen instructions will make it easy from there. The alternative is to use the Extension Manager’ in OpenOffice under the Extras menu. Extensions can be added, deactivated, or removed there.

Yet not every extension runs with every variant of OpenOffice. The safest bet, according to spokesman Florian Effenberger, is to use the current version, OpenOffice version 3. (Internet: http://extensions.services.openoffice.org, http://oooconv.free.fr/wikipedia/wikipedia_en.html, http://de.openoffice.org/downloads/komponenten.html, www.ooomacros.org, www.office-center-epj.de).

The computer helper: Intel’s new i7 chips – Core 7

The computer helper: Intel's new i7 chips Washington – Move over, Core 2 Duo. Move over, Core 2 Quad. Intel’s new i7 processor is showing up in new computers around the world. Intel is billing the i7 as “the best desktop processor in the world,” and indeed it offers some substantial improvements – in both speed and architecture – over previous models. But is the i7 worth your money? Will it make help you get your work done faster? And will it make your current PC obsolete? Read on for some answers.

Q: What’s new about the i7?

A: A lot. The i7 was designed from the ground up with speed and energy efficiency in mind. To maximise speed, the i7 includes an new, integrated memory controller that does away with the reliance of previous chips on the so-called “front side bus,” and in its place is a new data transmission channel dubbed QuickPath, which can transmit information at up to 25 gigabytes per second, depending upon chip version.

The first i7s out the door are quad-core designs, and all four cores are integrated onto the same piece of silicon for the first time to increase efficiency. Each core can process two instructions at once – a technology known as multithreading. Thanks to multithreading, each i7 processor looks like eight separate processing units to the operating system.

The i7s also introduce a new type of overclocking called “turbo boost.” Essentially, turbo boost temporarily pushes the performance of individual cores when a program requires it, squeezing more speed out of the chip than it normally provides. Thus chips can push themselves when processing demands are heavy, and they can throttle back to stock speeds under normal computing loads.

For power management and efficiency, the i7 includes a dedicated core that monitors power use, ensuring that the chip balances efficiency with suitable power usage.

Currently there are only three i7 chips available. The i7 920 runs each core at 2.66 GHz and is the most reasonably priced of the three – retailing for under 300 dollars. The i7
940 ups the clock rate per core to 2.93 GHz, but the price of this new chip almost doubles. At the very high end, Intel has the i7 Extreme Edition 965, which runs each core at
3.2 GHz and supports the highest QuickPath transmission speeds.

Q: How much faster are the new chips than today’s core 2 quad chips?

A: Significantly. For standard computing applications as well as processor-intensive video, graphics, and multimedia work, the top-of-the-line i7 processors are up to 64 per cent faster than best-of-breed chips from AMD or former-generation quad core chips from Intel itself.

There is one exception, however: games. The i7 provides little to no performance boost to many of today’s 3D games, mostly because current games do not take advantage of the multithreading technology that the i7 incorporates. Newer games should benefit more from the i7.

Q: Can I upgrade my current dual core processor with an i7?

A: No. The i7 processors use a different socket than today’s dual-core and quad-core processors. The i7 processor itself is larger than previous generation core 2 duo and core 2 quad chips. The larger size is necessary to accommodate the integrated memory controller and other features of the chip.

So if you wanted to upgrade your existing PC to use an i7, at the least you would have to purchase a new chip and a new motherboard – and either have the pair installed or, if you are tech savvy, install the combo yourself. Realistically you would probably also have to purchase new system memory. The i7 relies on DDR3 memory (RAM), which is not found in many systems today. The is the type of upgrade that would necessitate the purchase of an entirely new computer for most users.

Q: Are there both dual-core and quad-core i7 chips?

A: No. The i7 is a quad-core only processor, at least for now. It’s doubtful that a dual-core design will be produced. Four cores – and more – are clearly the future.

Q: If I’m buying a new computer, should I look for one with an i7 processor or look for good deals on machines with older processors?

A: In a period when the tech industry is moving to a new processor architecture, it’s usually not a good idea to look for deals on older technology. That’s because your upgrade path with the older technology will have a shorter lifespan, and the useful lifespan of your equipment may be lessened.

What’s more, the low-end i7 processor is priced competitively with today’s dual core and quad core processors, so you should not face a prohibitively higher price by going with the new technology. In the near term, however, the i7 chips are likely to be marketed in higher end computers. You should start to see prices of i7-based PCs moderate by the middle of this year.

Q: Can I get an i7 in a notebook computer?

A: No. Currently i7 processors are desktop-only. The new i7 chips generate a good deal of heat. Intel has stated that mobile versions of the chip should appear late this year.

Stonemart in Jaipur

Jaipur, Jan 13 (ANI): Largest exhibition on stones, ‘India Stonemart 2009′ drew large number of curious people in Jaipur.

The exhibition showcased a wide range of natural stones and supplementary stone products.

The four-day-long trade exhibition from January 8 drew stone traders from around ten countries.

“It was one of the largest stone exhibitions to be organised in India. All the stake holders involved in the industry like processor, machine suppliers, technology suppliers, architects and builders, everyone who is related with this can assemble together, to share ideas and to take actions to promote it in times to come.” said R K Gupta, CEO, Centre for Development of Stones.

With India producing 27 per cent of the stones produced in the world and exporting 11 per cent of the total global share, it is uniquely positioned to stage an event which is slated to become the largest expo on stone industry, anywhere in the world.

Local manufacturers also do feel that such events are helpful in show casing their products at a common platform so that buyers may get an opportunity to compare their products.

“Even though all the countries, whole world is suffering from financial crisis, we saw that India is one that suffers less and has more possibility to grow. It will also give other nations business opportunities to grow,” said Antonia, businessman from Italy.

India stands third, next to China and Italy only in stone production. India’s green marble is the pride of marble industry. Rajasthan alone contributes to around 65 per cent of total national production. By Lokendra Singh (ANI)
