The world's top 25 most energy-saving supercomputer unveiled

The world's most powerful computer is also the right of the green? This is in 2007 the world's top supercomputers behind a fundamental question. The ranking is based on floating-point operations per second performance and energy consumption ratio, that is, "millions of floating-point operations per second / per watt."

Virginia Tech's editor of the Green 500 list of supercomputers to people took note of the supercomputer designers should pay more attention to energy consumption, and not just concerned about the speed or computing power. The top 25 energy-efficient supercomputers are:

bin Laden October surprise, would attack Britain and the United States foreign facilities

September 24 in Pakistan and the United States-owned electricity Marriott Hotel terrorist attacks, the U.S. anti-terrorism intelligence refers to the "base" plan-Qaeda leader Osama bin Laden cooked up the "October surprise" and ordered the organization in the future a more attacks on British and American facilities overseas, In order to influence the U.S. election in November.

According to Hong Kong's "Ming Pao Daily News" quoted "New York Sun," said the end of August at the Republican and Democratic party held at the General Assembly, the United States intelligence agencies on the cut-off to hear from the "base" leadership.
These require high-level regional branch of the group stand by and wait for high-level instruction. The source said that information from a number of channels was intercepted by express mail to encrypt electronic information, and other means of communication have.

Yemen in the Middle East, an official of the local English newspaper yesterday quoted a "base" a spokesman for the organization warned that if the British and American diplomats not to leave Yemen, will launch a new round of attacks. Last week, Yemen's capital, the U.S. embassy bombing victims, "the base" has admitted responsibility.

U.S. counter-terrorism expert Crecy (RogerCressey) said: "predictable" base "will try to launch attacks around the world, to influence the November elections." He pointed out that the "base" lack the capacity to launch attacks in the United States, but " Is likely to be overseas for the United States and its allies to carry out high-profile attacks. "Intelligence experts estimate that the closer we get to the general election in November, the U.S. base in the interests of the greater threat. In fact, the Pakistani capital of the Marriott Hotel lobby, in recent years, the CIA is often used as a meeting place and the Pakistanis. The attack took place last Saturday, seems to be against the United States and its allies. "Foundation for the Defense of Democracy," Vice-Chairman Ross also said that the target may be the President of Pakistan Zardari. "He would have dinner at the Marriott Hotel." Ross said: "If they are in Pakistan for the first time the president made a speech after he was killed symbolic significance."

Clinton, who served as head of the intelligence Woolsey (JasmesWoolsey) pointed out that the "base" to launch attacks in the past have tried to influence the outcome of democratic elections, for example, on March 11, 2004, the "base" in a Madrid train bomb attacks launched by As a result, 3 in the future of the leftist opposition to the Iraq war won the election came to power; In addition, last year's assassin also killed trying to return to Pakistan and then when the prime minister Benazir. "They also tried in the past the turn of the old and new leaders to disseminate information to voters." Mak camp have admitted that before the election in the event of a large-scale terrorist attack, the national security card to play on McCain's favorable election.
