Blue Gene is an IBM project aimed at designing supercomputers that can reach operating speeds in the petaFLOPS (PFLOPS) range, with low power consumption. The project created three generations of supercomputers, Blue Gene/L, Blue Gene/P, and Blue Gene/Q. Blue Gene systems have often led the TOP500 and Green500 rankings of the most powerful and most power-efficient supercomputers, respectively. Blue Gene systems have helped to map the human genome, investigate medical therapies, simulate radioactive decay, replicate brainpower, fly aeroplanes, pinpoint tumours, predict climate trends and identifiy fossil fuels—all for less time and money than would have been required to physically complete these tasks.
