Tianhe-2, Chinese supercomputer named as world’s fastest

BEIJING (AP) — A Chinese university has built the world’s fastest supercomputer, almost doubling the speed of the U.S. machine that previously claimed the top spot and underlining China’s rise as a science and technology powerhouse.

http://www.huffingtonpost.com/2013/06/18/tianhe-2_n_3458981.html The Tianhe-2 has a peak performance speed of 54.9 quadrillion operations per second.

The semiannual TOP500 listing of the world’s fastest supercomputers released Monday says the Tianhe-2 developed by the National University of Defense Technology in central China’s Changsha city is capable of sustained computing of 33.86 petaflops per second. That’s the equivalent of 33,860 trillion calculations per second.

The Tianhe-2, which means Milky Way-2, knocks the U.S. Energy Department’s Titan machine off the No. 1 spot. It achieved 17.59 petaflops per second.

Supercomputers are used for complex work such as modeling weather systems, simulating nuclear explosions and designing jetliners.

It’s the second time a Chinese computer has been named the world’s fastest. In November 2010, the Tianhe-2′s predecessor, Tianhe-1A, had that honor before Japan’s K computer overtook it a few months later on the TOP500 list, a ranking curated by three computer scientists at universities in the U.S. and Germany.

The Tianhe-2 shows how China is leveraging rapid economic growth and sharp increases in research spending to join the United States, Europe and Japan in the global technology elite.

“Most of the features of the system were developed in China, and they are only using Intel for the main compute part,” TOP500 editor Jack Dongarra, who toured the Tianhe-2 facility in May, said in a news release. “That is, the interconnect, operating system, front-end processors and software are mainly Chinese.”

Beware of Malaysian Chinese school leavers being lured into dubious degree and diploma programs !

如果您现在对前途很迷惑、很模糊,我真诚真诚真诚的希望刚毕业的您能看完我写的东西。在2009年还未考SPM之前,我校的一位华文老师突然接获一 位女子送来的几张表格,因为老师说那位女子自己本身也曾经历一段困难的事,所以现在要提供奖学金帮助即将要毕业的贫穷学生,以做慈善。当时,也有很多学生 向老师拿那表格,我来自家境中等的也拿了那张表格。表格内没注明她的来历、名字或公司,只是叫学生…

"I have a question here. Are u opening some sort of tuition center like Super Tution Centre? There are a lot in Malaysia now, with poor quality teachers that just passed out from secondary school, and take some sort of stupid lousy diploma or degree in business management from some lousy uni shakehead.gif , claimed themselves as full A’s and degree holder qualify and quality teacher, by falsification and alter the SPM result shocking.gif ."

Upset over US cyber spying!

There are increasingly strong reactions to revelations that United States agencies are spying on Internet use by Americans and foreigners as well as planning cyber actions on foreign targets.

 
Weekend News Round-up: US cyber spying whistle-blower revealed; is Snapchat worth US$1bn?

THE revelations of data collection on a massive scale by the United States’ security agencies of details of telephone calls and Internet use of its citizens and foreigners are having reverberations around the world.

Much of the responses have been on the potential invasion of privacy of individuals not only in the United States but anywhere in the world who use US-based Internet servers.

Also revealed is a US presidential directive to security agencies to draw up a list of potential overseas targets for US cyber-attacks.

This lays the Unites States open to charges of double standards and hypocrisy: accusing other countries of engaging in Internet snooping or hacking and cyber warfare, when it has itself established the systems to do both on a mega scale.

The revelations, published in the Guardian and Wall Street Journal, and based on a leak by a former US intelligence official, include that US security agencies have access to telephone data of Verizon Communications, AT&T and Sprint Nextel, as well as from credit card transactions.

They also can access data from major Internet companies – Google, Yahoo, Microsoft, Facebook, AOL, Apple, PalTalk, Skype and YouTube—under the Prism surveillance programme.

Millions of Internet users around the world use the servers or web-based services of the companies mentioned.

Two American citizen groups, the American Civil Liberties Union (ACLU) and the New York Civil Liberties Union, have filed a lawsuit against the US administration.

“Those programmes constitute unreasonable intrusions into American’s private lives that’s protected by the Fourth Amendment (on search and seizure),” said Brett Kaufman of the ACLU, as quoted by IPS news agency.

Governments and people outside the United States are equally upset, or more so, that they apparently are also covered by the massive US surveillance programme.

The European Union’s commissioner of justice Viviane Reding has written to the US attorney general asking if European citizens’ personal information had been part of the intelligence gathering, and what avenues are available for Europeans to find out if they had been spied on.

In China, commentators and opinion makers are citing double standards on the part of the United States.

An article in the China Daily commented that the massive US global surveillance programme as revealed is certain to stain Washington’s overseas image and test developing China-US ties.

An editorial in another Chinese paper, Global Daily, stated: “China needs to seek an explanation from Washington.

“We are not bystanders. The issue of whether the United States as an Internet superpower has abused its powers touches on our vital interests directly.”

In their summit last week in California, United States President Barack Obama reportedly pressed Chinese President Xi Jinpeng to curb cyber-spying by Chinese agencies and companies.

The breaking news about the United States snooping on Internet users must have caused some discomfort to Obama when bringing up this issue.

A Chinese Foreign Ministry spokesperson last week reiterated that “China is also a victim to the most sophisticated cyber hacking”.

Though less publicised, a part of the leaks published in the Guardian, was a 18-page directive from President Obama to his security and intelligence officials to draw up a list of potential overseas targets for US cyber-attacks.

The October 2012 directive states that what it calls Offensive Cyber Effects Operations (OCEO) “can offer unique and unconventional capabilities to advance US national objectives around the world with little or no warning to the adversary or target and with potential effects ranging from subtle to severely damaging”, according to the June 7 Guardian article by Glenn Greenwald and Ewen MacAskill.

The directive says the government will “identify potential targets of national importance where OCEO can offer a favorable balance of effectiveness and risk as compared with other instruments of national power”.

The aim of the document was “to put in place tools and a framework to enable government to make decisions” on cyber actions, a senior administration official told the Guardian.

Obama’s move to establish a potentially aggressive cyber warfare doctrine will heighten fears over the increasing militarisation of the Internet, comments the Guardian article.

It adds that the United States is understood to have already participated in at least one major cyber attack, the use of the Stuxnet computer worm targeted on Iranian uranium enrichment centrifuges, the legality of which has been the subject of controversy.

In the presidential directive, the criteria for offensive cyber operations in the directive is not limited to retaliatory action but vaguely framed as advancing “US national objectives around the world”.

Obama further authorised the use of offensive cyber attacks in foreign nations without their government’s consent whenever “US national interests and equities” require such non-consensual attacks. It expressly reserves the right to use cyber tactics as part of what it calls “anticipatory action taken against imminent threats”.

The Guardian commented: “The revelation that the US is preparing a specific target list for offensive cyber-action is likely to reignite previously raised concerns of security researchers and academics, several of whom have warned that large-scale cyber operations could easily escalate into full-scale military conflict.”

Meanwhile, UN Human Rights Council’s Special Rapporteur Frank La Rue issued a report on June 4 on the increasing use of surveillance, warning that unfettered state access to surveillance technologies could compromise human rights to privacy and freedom of expression, as protected by the Universal Declaration of Human Rights and the International Covenant on Civil and Political Rights (ICCPR).

The report warned too against the use of “an amorphous concept of national security” as a reason to invade people’s rights to privacy and freedom of expression, arguing that such an invasion potentially “threatens the foundations of a democratic society”.
