World's fastest super computer!!!

U.S. has gone a long way in inventing a lot of things. The U.S. Department of Energy announced Monday that its new supercomputer "Roadrunner" had successfully performed 1,000 trillion calculations per second which emerges to be the fastest in the world.

Roadrunner will be used by the DoE's National Nuclear Security Administration (NNSA) to perform calculations that vastly improve the ability to certify that the U.S. nuclear weapons stockpile is reliable without conducting underground nuclear tests, according to a statement released by DoE.

Roadrunner will be housed at NNSA's Los Alamos National Laboratory in New Mexico. The laboratory worked with manufacturer IBM for six years to develop the super machine, which can meet "the nation's evolving national security needs."

The 100-million-dollar machine has redefined the frontier of supercomputing by crossing the one petaflop threshold.

A "flop" is an acronym meaning floating-point operations per second. One petaflop is 1,000 trillion operations per second.

To put this into perspective, if each of the 6 billion people on earth had a hand calculator and worked together on a calculation 24 hours per day, 365 days a year, it would take 46 years to do what Roadrunner would do in one day.

Roadrunner is twice as fast as IBM's Blue Gene supercomputer at Lawrence Livermore National Laboratory, which itself is three times faster than any of the world's other supercomputers, according to IBM.

This new superfast computer will also offer important access to track the aging nuclear weapon stockpile in the United States.
