Titan Captures Liquid-Crystal Film Complexity

Apr 14, 2014 |

Liquid-crystal displays (familiar to most as LCDs) rely on the light modulating properties of liquid crystals to bring images to life on a wide variety of screens. From computer monitors to televisions to instrumental panels and signage, LCDs are a pervasive element of modern life. LCDs employ high-tech films, which must be both thin and Read more…

Ice-Repellant Materials One Step Closer

Sep 12, 2013 |

Scientists at GE Global Research are using the multi-petaflop Titan supercomputer at Oak Ridge National Laboratory to study the way that ice forms as water droplets come in contact with cold surfaces. They are working to develop “icephobic” materials that prevent ice formation and accumulation.

Ford Taps ORNL to Boost Vehicle Airflow, Fuel Efficiency

Aug 19, 2013 |

Anybody who drives one of Ford’s recent vehicles spends a little less money on gasoline thanks to HPC work the carmaker undertook with Oak Ridge National Laboratory, where more than one million processor hours were spent getting a handle on the complex fluid dynamics governing airflow under the hood.

Vampir Rises to the Occasion at ORNL

Jul 31, 2013 |

Researchers are licking their chops with the potential to speed the execution of parallel applications on the largest supercomputers using Vampir, a performance tool that traces events and identifies problems in HPC applications.

Kraken Chews on Gribble Data for Industrial Enzyme Research

Jun 25, 2013 |

A diminutive marine crustacean called the Gribble landed on the biofuel industry’s radar for its unique ability to digest wood in salty conditions. Now, researchers in the US and the UK are putting the University of Tennessee’s Kraken supercomputer to work modeling an enzyme in the Gribble’s gut, which could unlock the key to developing better industrial enzymes in the future.

Titan Didn’t Redo LINPACK for June Top 500 List

Jun 13, 2013 |

Titan, the Cray XK7 at the Oak Ridge National Lab that debuted last fall as the fastest supercomputer in the world with 17.59 petaflops of sustained computing power, will rely on its previous LINPACK test for the upcoming edition of the Top 500 list.

Debugging at Titan Scale

Apr 15, 2013 |

Getting scientific applications to scale across Titan’s 300,000 compute cores means there will be bugs. Finding those bugs is where Allinea DDT comes in.

Releasing the Kraken on Protoplanetary Disks

Apr 2, 2013 |

The large-scale classical physics problems that remain unsolved must for the most part be run in parallel by high-performance machines like the Kraken supercomputer. Literally millions of variables culled from billions of particles combine to make this type of research unreasonable for ordinary computational physics.

What Will the Sequester Mean to HPC (and Federal) Research?

Mar 20, 2013 |

<img src=”http://media2.hpcwire.com/hpcwire/argonne_crop.jpg” alt=”” width=”94″ height=”72″ />Prominent figures in government, national labs, universities and other research organizations are worried about the effect that sequestration and budget cuts may have on federally-funded R&D in general, and on HPC research in particular. They have been defending the concept in hearings and in editorial pages across the country. It may be a tough argument to sell.

World’s Fastest Supercomputer Hits Speed Bump

Feb 27, 2013 |

When it comes to Titan’s final acceptance testing, ONRL says not so fast.
