Quantum Processor Hits 99.9 Percent Reliability Target

Apr 25, 2014 |

Physicists at UC Santa Barbara (UCSB) have taken a huge leap forward towards what they refer to as a “fully functional quantum computer” – long-considered the holy grail of both physics and computing. The five cross-shaped elements are the Xmon variant, so named by the team, of the transmon qubit placed in a linear array. A Read more…

Programming for Unreliable Hardware

Nov 11, 2013 |

As transistors approach sub-atomic sizes, reliability is increasingly jeopardized. Chipmakers keep figuring out technical workarounds to the miniaturization problem; however, prevailing wisdom maintains that current manufacturing techniques will sooner or later run out of steam, and Moore’s Law – the prediction that has yielded huge increases in semiconductor performance for nearly five decades – will Read more…

Controlling Soft Errors at Scale

Oct 2, 2013 |

There are many important issues when it comes to advancing the field of HPC toward the exascale era, but among all these variables, there are about five or so sticking points that really stand-out: one of these is controlling for soft errors. As the number of cores per machine increases, incorrect behaviors, known as soft Read more…

The Week in HPC Research

Mar 14, 2013 |

<img src=”http://media2.hpcwire.com/hpcwire/test_tube_image_200x.jpg” alt=”” width=”93″ height=”61″ />The top research stories of the week include the 2012 Turing Prize winners; an examination of MIC acceleration in short-range molecular dynamics simulations; a new computer model to help predict the best HIV treatment; the role of atmospheric clouds in climate change models; and more reliable HPC cloud computing.

Bad Moon Rises Over Cloud Perceptions

Apr 28, 2011 |

It’s a glorious day for those with backup and recovery services to pitch, not to mention for those who are nipping at the heels of Amazon Web Service’s cloud empire. On the flip side, for those who just got word that their data is unrecoverable via a short letter, not to mention those who have been proclaiming cloud computing as the safe bet for mission critical applications–it’s been quite a bleak morning.

DOE Research Group Makes Case for Exascale

Feb 21, 2011 |

Exascale computing promises incredible science breakthroughs, but it won’t come easily, and it won’t come free.
