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…

Titan Expands on Molecular Dynamics Discovery

Dec 13, 2013 |

Thanks to the power of supercomputing, scientists at Oak Ridge National Laboratory (ORNL) and the University of Tennessee (UT)–ORNL Joint Institute for Computational Sciences (JICS) have discovered a molecular “switch” in a receptor that controls cell behavior. To allow for an even more detailed simulation and a better understanding of the primary molecular switch that controls cell behavior, scientists Read more…

Titan Gets A Little Help

Nov 18, 2013 |

With the announcement of the 42nd TOP500 list at SC13 in Denver today, Titan, the 17.6 petaflop (Rmax) Cray XK7 system installed at the Department of Energy’s (DOE) Oak Ridge National Laboratory, held onto its number-two spot for another year, but in this era of big data, even the largest supercomputer in the United States 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.

Big Rig Redesign Still Going Strong

Aug 26, 2013 |

In 2011, South Carolina-based BMI Corp. worked with researchers at Oak Ridge National Laboratory (ORNL) to develop a technology that improves the aerodynamics of long haul tractor trailers, thereby boosting fuel efficiency. Two years later, the company and the partnership are still going strong.

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.

Spider II Emerges to Give ORNL a Big Speed Boost

Aug 16, 2013 |

When the Jaguar supercomputer at Oak Ridge National Laboratory morphed into Titan in 2012, it delivered a huge increase in computational power. Recently, the ORNL’s parallel file system, called Spider, received a similar overhaul, and is in the process of emerging as Spider II.

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.

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.

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.
