Definition: teraFLOPS

(tera FLoating point OPerations per Second) One trillion floating point operations per second. IBM's BlueGene/L supercomputer, designed for computational science at Lawrence Livermore National Laboratory, was upgraded in 2007 from 65,536 to 106,496 processing nodes, where each added node had twice the memory of the old. The result for BlueGene/L: a peak speed of 596 teraFLOPS.

Human TeraFLOPS
It has been said that the human brain processes 100 teraFLOPS; however, the older one gets, that seems to be a gross exaggeration!
