Noun
petaflop (plural petaflops)
- (computing) Either of two units of measure of the calculating speed of a computer:
- a quadrillion (10¹⁵) floating point operations per second.
- 1992 March 2, Richard Preston, The New Yorker, "The Mountains of Pi":
- ...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 New Yorker, "The Mountains of Pi":
- 1,125,899,906,842,624 (2⁵⁰) floating point operations per second.
