As http://www.hpcwire.com reported on January 14 2010, it was learned from the National Supercomputing Center in Tianjin January 13 that the adjustment of the first parts to be installed in "Tianhe-1," China’s first supercomputer which is capable of doing more than a quadrillion calculations per second, has been completed.
This signifies that the supercomputer is qualified to provide service for clients and the first parts to be installed in "Tianhe-1" have been in trial use among important clients.
The calculation capability of the first "Tianhe-1" systems that have already reached Tianjin is one-tenth of a fully-installed "Tianhe-1."

As http://www.hpcwire.com reported on December 16 2009, Fixstars Corporation announced the release of the beta version of its OpenCL Compiler "FOXC" for the x86 architecture starting today. This will allow software developers to take full advantage of multicore x86 CPUs to develop OpenCL-based softwares. The "FOXC" Beta version can be downloaded for free from its Web site.
OpenCL is a parallel computing framework for programming multicore systems, such as multicore CPUs, GPUs, Cell/B.E., DSPs. The framework, which is a product of joint effort by the world’s leading semiconductor makers and hardware vendor, is attracting attention as an efficient and highly portable open technology for software development.

"We recognize that this may well mean having to shut down Google.cn and potentially our offices in China."
— David Drummond, Google chief legal officer
"While removing search results is inconsistent with Google’s mission, providing no information… is more inconsistent with our mission."
— Google statement
There’s no doubt that this is another tragedy after the Baidu’s being attacked. The Google staff in China even felt that they were abandoned.
Google, the world’s leading search engine, has thrown down the gauntlet to China by saying it is no longer willing to censor search results on its Chinese service.
The internet giant said the decision followed a cyber attack it believes was aimed at gathering information on Chinese human rights activists.

These days, the hottest news about Internet in China is that Baidu was attacked. Yanhong LI, the CEO of Baidu, even said it was unprecedented in history.
As reported, the most popular Web search engine in China, Baidu.com, was attacked by a group of hacktivists identifying themselves as the Iranian Cyber Army. The hackers hijacked the domain’s DNS records and pointed it to a server under their control.
Baidu is a Chinese search engine established in 2000. According to the Alexa traffic ranking, the website is currently number one in China and eight in the world. Additionally, Baidu.com dominates the search engine market in the country with over a 77 percent share.
The attack against the search engine occurred yesterday (January 12 2009), when for about three hours, its main page displayed the image of the Iranian flag and a message reading "THIS SITE HAS BEEN HACKED BY IRANIAN CYBER ARMY." Additional text written in Persian translates amongst the lines of "The Iranian Cyber Army has been established in protest to foreign countries and Zionists interfering in the domestic affairs of our country and broadcasting false news."

Years ago, home computers were powered by single-core processors, and in time, dual- and quad-core designs emerged which meant that two of four cores were placed alongside each other.
NOW, experts are looking to create 3D microprocessors, in which the cores will not be stacked next to each other, but on top of each other.
The vertical stacking allow for a much higher transfer speed between the cores – up to 10 times faster than currently possible – as well as for improved heat efficiency and overall performance.
But, efficiency is not the only reason why 3D architectures are researched. It is predicted that the supercomputers of 2100 would theoretically use up the whole of the US’ electrical supply. A new, revolutionary cooling system that would further reduce temperatures inside future 3D microprocessors is being studied now. The architecture of 3D microprocessor and its comparison with today’s multichip can be seen in the right picture.
