NCSA Mixes GPUs into Blue Waters

NCSA  is  excited  about  the  inclusion  of  NVIDIA's  Tesla  GPUs  in  Blue  Waters.    GPUs  provide  extraordinary  capabiliWes  for  numerically-­‐intensive  computaWons  and  a  cost-­‐effecWve,  energy-­‐efficient  way  to  build  tomorrow's  petascale  supercomputers.
