petaflops
Quadrillion calculations per second
Petaflops is a measure of computing speed—one quadrillion floating-point operations per second.
The term combines the metric prefix peta- (10^15) with FLOPS (floating-point operations per second).
Supercomputers are rated in petaflops: The new system can sustain 200 petaflops.
A single petaflop represents roughly a million billion calculations every second.
