Meet the Exascale Apps

Apr 12, 2012 |

In what will be a three-decade span between gigascale and exascale computing, HPC capability will have increased by a factor of one billion, but the apps that are projected to use this enormous increase in capability look pretty much like the gigascale ones. Are we missing opportunities as we push the apex of HPC higher?

Jailbreaking HPC

Mar 5, 2012 |

<img style=”float: left;” src=”” alt=”” width=”100″ height=”75″ />Is high performance computing in jail? Traditional wisdom has held that that the engines of HPC are unique, its people are scarce, and the resources need to be held close in protected locations, its “temples.” But those attitudes are out of sync with today’s realities, and are holding back the technology’s true potential.

Number Crunching, Data Crunching and Energy Efficiency: the HPC Hat Trick

Feb 2, 2012 |

<img style=”float: left;” src=”” alt=”” width=”88″ height=”48″ />In the world of high performance computing, there are three distinct metrics in play: number crunching speed, data crunching speed, and energy efficiency. Can a computer excel at all three, or is our best recourse to try for something less than a hat trick?
