IBM has recently announced an even speedier supercomputer, just after seven months it came out with world's fastest supercomputer. The new one however is being learnt to have computing power of 2 million laptops.

On Tuesday, IBM informed that it is working to come up with technology for its new Sequoia computer, with delivery scheduled in 2011 to the Department of Energy for use at Lawrence Livermore National Laboratory.

The new supercomputer dubbed as Sequoia will guzzle along at 20 petaflops per second. In comparison to the older machine, which IBM came out with in June, the latest one is one order of magnitude quicker. The earlier machine delivered to the Energy Department, broke the 1 petaflop barrier.

Basically peta means a term for quadrillion, whereas FLOP stands for floating point operations per second.

It has been learnt that Sequoia, and a smaller computer called Dawn are being developed in Rochester, Minnesota, for purpose in simulating nuclear tests. Furthermore, it was also informed by the company that complex tasks like weather forecasting or oil exploration is also where these computers can be utilized.

"Sequoia will be highly energy-efficient for the job it does but even so will occupy 96 refrigerator-sized racks in an area the size of a big house -- 3,422 square feet (318 square meters)," said IBM in a release.
