one quadrillion FLOPS
Full Definition

A petaflop refers to the ability of a computer to do one quadrillion (one million billion or) floating point operations per second (FLOPS).

A petaflop computer requires a massive number of computers working in parallel on the same problem.  Applications might include real-time nuclear magnetic resonance imaging during surgery or even astrophysical simulation.
Today's fastest parallel computing operations are capable of petaflop speeds. The world's fastest supercomputer today, Titan at Oak Ridge National Laboratory, is capable of 17.59 petaflops and costs $100 million.
