1 petaflop barrier

Wow, some scepticists were mentioned 2010-12, but nobody predicted that in 2009 we are going to cross the 1 petaflop barrier in computations and the power available today with two supercomputers listed on www.top500.org where one is Roadrunner and another one is Jaguar. 1 petaflop is equivalent to thousand trillion floating point operations per second.
