In computing, FLOPS (or flops or flop/s) is an acronym meaning FLoating point Operations Per Second.

The FLOPS is a measure of a computer's performance, especially in fields of scientific calculations that make heavy use of floating point calculations, similar to instructions per second. Since the final S stands for "second", conservative speakers consider "FLOPS" as both the singular and plural of the term, although the singular "FLOP" is frequently encountered.

Alternatively, the singular FLOP (or flop) is used as an abbreviation for "FLoating-point OPeration", and a flop count is a count of these operations (e.g., required by a given algorithm or computer program).

In this context, "flops" is simply the plural rather than a rate.

NEC's SX-9 supercomputer has the world's first vector processor to exceed 100 gigaFLOPS per single core. IBM's supercomputer dubbed Blue Gene/P is designed to eventually operate at three petaFLOPS. However, the IBM Roadrunner is the first supercomputer to sustain one petaFLOPS.
