IBM's Sequoia has come out on top on the list of the world's fastest supercomputers for the US.

The newly installed system trumped Japan's K Computer made by Fujitsu which fell to second place, the BBC reported.It is the first time the US can claim pole position since it was beaten by China two years ago.

David Turek, vice president of deep computing at the firm, told the BBC his company had been preparing to retake the top spot for two years. Substantial planning went into this. We knew the day would come,” he said.

Sequoia is 1.55 times faster than the Fujitsu model, and uses over 1.5 million processors.

The Top500 list of the world’s fastest supercomputers is released every six months and compiled by Hans Meuer of the University of Mannheim in Germany, Erich Strohmaier and Horst Simon of the Lawrence Berkeley National Laboratory and Jack Dongarra of the University of Tennessee in Knoxville. The latest list was released Monday at the 2012 International Supercomputer Conference in Hamburg, Germany. Read More

Sequoia is located at the Lawrence Livermore National Laboratory in Livermore, Calif. It was installed there in 2011 and will be fully deployed in 2012 for work on behalf of the National Nuclear Security Administration. The supercomputer was created for use by the Department of Energy’s National Nuclear Security Administration (NNSA), which was established by Congress in 2000 to manage the nation’s nuclear weapons stockpile and prevent nuclear proliferation, among other responsibilities.

China and Germany both have two supercomputers, while Japan, France and Italy have one.But IBM proved to be the leading manufacturer claiming five out of the top 10 spots.

Microsoft tablet - windows 8 poweredMicrosoft yesterday (18th/June/2012) unveiled its own Windows-powered tablet computer called Surface, altering its strategy of focusing on software and relying on partners to make the machines in a renewed attempt to take on Apple's iPad.
This puts Microsoft in competition with other manufacturers planning to release tablets designed for Windows 8.

The touchscreen computers will be powered by its upcoming Windows 8 system and contain a choice of an Intel or ARM-based processor.

The devices have 10.6 inch (26.9cm) displays, built-in kickstands and are housed in magnesium cases - which the microsoft described as the first of their kind. The device's cover serves as a track pad and a full keyboard.

ARM-based tablets are 9.3mm (0.4 inches) thick - slightly less than the iPad - and run the Windows RT version of the new system. The Verge reported that the chipset will be built by Nvidia. Read More

The versions using Intel's x86 technology run Windows 8 Pro and are 13.5mm (0.5 inches) thick. The specifications mean the Surface tablets have bigger screens than the iPad but are heavier. 

The new strategy threatens to sour Microsoft's relationship with some PC makers, many of which have been investing to develop their own Windows 8 tablets and may not want to compete directly with Microsoft.

The software maker is aiming to release Windows 8 in time for the end-of-year holidays and will have a version for x86 chips from Intel and for ones based on ARM Holdings's technology, which is also used in the iPad. The Surface tablet will be available in versions running both chip designs.

Microsoft said the Surface's price will be announced closer to when the devices are available and will be "competitive with a comparable ARM tablet or Intel Ultrabook-class PC."

The world's largest software maker is stepping up its assault on the tablet market as consumers choose the devices over laptops, weakening the personal-computer market and curbing Windows revenue.

It's no secret that notebook screens are getting wider and wider. While 5:4 and 4:3 used to be the conventional aspect ratios in the past, nowadays all we see is 16:9 and 16:10 widescreen panels. Toshiba takes things even further with its new U845W Ultrabook. The laptop has a 14.4" screen with a 21:9 aspect ratio. The screen has a 1792x768 pixel resolution, making the pixel density similar to that of a 1600x900 panel of equal size.

The U845W is part of Toshiba's new 14" Satellite Ultrabook series. These devices are powered by Intel's Ivy Bridge processors, use SSDs for storage and have illuminated keyboards. The laptop doesn't have a numeric keypad, which, given the width of the device, would have been a nice addition. The battery should last around 7.5 hours. Toshiba's U845W Ultrabook weighs 1.75 kg and is about 2 cm thick. Connectivity includes three USB 3.0 connectors, HDMI and ethernet.

Intel world’s biggest chipmaker said while touchscreen enabled super-thin “ultrabooks” are the focus of attention for tech industry players gathered in Taiwan this week (E13), by 2013 the buzz will have moved on to voice and gesture recognition features.

Intel is counting on ultrabooks - ultra-thin notebook PCs similar to Apple Inc’s Macbook Air and offering some of the technological chic of tablets - to revive a PC market languishing due to the growing popularity of the iPad.

Despite the economic hardtimes and higher retail price, Intel expects the touch ultrabook will be well received by the market and it will enter agreements with four Taiwanese touch panel makers on Tuesday to enable the expansion of the current capacity for touch-enabled ultrabook convertible designs by 3-5 times.

According to Tom Kilroy Intel’s Senior Vice President and General Manager of Sales and Marketing, Touch will be a major attribute in terms of purchase criteria for ultrabook and notebook, and I think the attention we will be talking about next year will be around voice and gesture.

Computex electronics trade fair:
This year it will feature around 30 touch-enabled ultrabook designs with various styles of foldable, detachable or sliding keyboards. More than 20 tablet designs will also be showcased based on the forthcoming 32nm Intel Atom SoC processor, codenamed “Clover Trail”, and running Microsoft’s new Windows 8 system.

Logitech announced the expansion of its solar offering with the new Logitech® Wireless Solar Keyboard K760 for Mac®, iPad® or iPhone®. A continuation of Logitech’s solar series, which started with the Logitech® Wireless Solar Keyboard K750 and has continued with the Logitech® Solar Keyboard Folio for iPad, this new keyboard adds Bluetooth® connectivity with an easy-switching capability. It allows you to simultaneously pair multiple devices and quickly switch among them with the push of a button.

The Logitech Wireless Solar Keyboard K760 is stylish and compact with onboard solar cells for hassle-free charging.
