Either of two units of measure of the calculating speed of a computer: ▸ a quadrillion (10¹⁵) floating point operations per second.
...a better machine is a petaflop machine. A petaflop is a quadrillion flops, a quadrillion floating-point operations per second, so a petaflop machine is a thousand times as fast as a teraflop machine, or a million times as fast as a Cray Y-MP8. The petaflop machine will exist by the year 2000, or soon afterward.
1992 March 2, Richard Preston, “The Mountains of Pi”, in The New Yorker:
