The US military's Roadrunner supercomputer has become the first machine to calculate at more than a quadrillion (10~(15)) operations per second, thereby crossing the petaflop barrier. The record was technically set on 25 May, in IBM's laboratories in Poughkeepsie, New York, using the UNPACK standard benchmark for comparing supercomputer performance. In early June, however, it achieved petaflop performance on a real-life application of modelling the human cortex, says David Turek, vice-president for 'deep computing' at IBM.
