The new top computer built in China is powered by over 7,000 Nvidia graphic processor units. The new supercomputer is considered as the world’s fastest computer created to date.

The supercomputer was built by the National University of Defense Technology located at the National Supercomputing Center in Tianjin, China. According to Nvidia officials, it has a horsepower equivalent to about 175,000 laptop computers.

This top computer is called Tianhe-1A, which is thought to be used currently by several scientists across different fields and will be made available in some other countries.

Nvidia is well known for creating plug-in video cards found in high-end gamer computer. However, they are now promoting their technology that it may be used for other purposes apart from graphics. This includes supercomputer’s running simulations in astrophysics, as well as other math-heavy tasks.

The supercomputer is also expected to be used in medical imaging, weather forecasting, as well as oil exploration.

The graphic processors, also called GPUs, do well in performing several small calculations at the same time. This makes them useful for several kinds of tasks. The graphic chips used in the Tianhe-1a are high-end cards that can be sold at about $2,500 each.

According to Nvidia, seven of the world’s most powerful computers are found in the United States, with two of them in China and one in Germany.

Some experts think that most programmers and semiconductor players focus on central processors. However, they believe that GPUs should be utilized more to improve the performance of everyday computers, which include desktops, PCs and tablets.

The Hewlett-Packard Co revealed its first and newest product for the rapid-growing tablet market. The HP slate tablet is a device that runs on Windows 7 software intended for business-minded customers.

The HP Slate 500 tries to reproduce the PC feel and experience in a tablet form, thus creating a distinction between rivals who have released devices with a smartphone feel. The device is running on Microsoft Windows 7, which is the same version used by most companies for their standard personal computers.

The slate is sold at a starting price of $799, which is higher than other competing devices such as Apple’s iPad that started the tablet craze when it was released earlier this year.

HP offers a slate tablet with 8.9-inch, multi-touch enabled screen. It weights 1.5 pounds, a digital stylus pen and 64 gigabytes storage. Its battery can last up to five hours.

The slate is installed with Wi-Fi access; however, it has no built-in 3G internet access unlike other similar devices such as iPad, Galaxy Tab and Samsung Electronics.

The director of business notebook marketing at HP, Carol Hess-Nickels, gave importance to the tablet’s usefulness when it comes to business activities and applications. The device can benefit retail, insurance and healthcare companies the most among other entrepreneurs.

The HP Slate comes with Intel Atom processor, unlike other rival tablets that runs on low-power ARM-based chips found in smart handy phones.

The device has a front and back camera that allows video conferencing, as well as a USB port. It also consists of a case and docking station. The Slate is now available for sale online.

Hewlett-Packard Co, the world’s largest PC maker, is also planning to release a tablet that may look different from the Slate next year.

Apple Inc. is reaching out to Verizon Wireless to assist in selling the iPad this Christmas, thus weakening their sturdy tie-up between AT&T Inc. The gadget will be available in both companies this Thursday, October 28.

The surprising news created a disturbance between the relationship of AT&T Inc. and Apple.  AT&T Inc. was the exclusive carrier of iPhone, and was primarily tapped as the network that will give the iPad’s mobile plan when this computer tablet was released last spring.

Apple’s iPad are priced equally by both companies. On the other hand, Verizon will be offering the gadget with a mobile Wi-Fi hotspot bundle that will work for their network.

Walter Piecyk, a BTIG analyst said that the decision of Apple to sell the iPad through Verizon is a simple one. He said that Apple wants to sell more products of these as possible and this decision will truly sell more items. Piecyk said that if Verizon’s network works better, then why not Apple sells the iPad tablets there.

He said that Verizon’s retail sales will help them be accustomed with the tablet’s software, as well as to prepare them from selling iPhone items. These two gadgets share the same operating system.

Verizon is pushing a high-speed connection by bundling the gadget to its portable hotspot. Prices start from $629 for the 16 Gigabyte iPad reaching to $829 for the 64 Gigabyte model.

Verizon Wireless has about 2,000 stores compared to AT&T’s 2,200. Their shares closed up to 0.7 percent while AT&T shares increased to 0.1 percent. Evidently, Apple climbed to 0.7 percent shares.

Amazon.com is said to be launching their applications store for Google Inc’s Android Mobile platform by the Wall Street Journal on Thursday.

If this will happen, Amazon will be in competetition with other available application stores online from Apple Inc., as well as from Google itself.

Amazon.com is America’s largest online retailer. Just recently, they started selling eBook contents through the Kindle platform. Although few application games have been released for Kindle, an application store that would be used for several Android phones and tablets would benefit the online shopping giant.

The Amazon spokesman, when asked for any feedback regarding the speculations, replied through email that they have not announced anything yet. On the other hand, Google did not mention anything about it. According to the Google spokesman, they do not comment on rumor or speculation.

Amazon has wanted to become a software selling company. Based on the given report from Wall Street Journal, the company only wants a 30% cut of profit. This means, application developers will get a total of 70 percent revenue from sales.

The 70/30 revenue sharing arrangement is actually the same as what Apple uses for its application developers.

Google’s Android Marketplace only has 80,000 applications while Apple’s applications store has more that 270,000 apps to boast.

Android mobile has been gaining popularity around several smartphone users. They have even begun competing with Apple iPhone handset. Several devices are already Android-installed such as Samsung’s Galaxy S and Motorola’s Droid.
