That machine, the Titan Supercomputer, is capable of churning through more than 20,000 trillion calculations each second or 20 petaflops. (1 petaflop = 1 quadrillion instructions per second).

The potential for our understanding of the universe has taken a giant leap forward after Frontier, a supercomputer based in the Oak Ridge ... times faster than similar simulations of Saturn's moon ...

Frontier, the second fastest supercomputer in the world, used dark matter and the movement of gas and plasma rather than just gravity to model the observable universe.
