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…

NVIDIA Highlights GPU Progress on Titan Supercomputer

Mar 27, 2014 |

The GPU Technology Conference this week in San Jose offered plenty of material for the supercomputing set with a number of presentations focused on specific programming challenges for large-scale scientific and enterprise HPC applications. The Titan system at Oak Ridge National Lab tied together key themes through a number of the talks, which helped put Read more…

GPUs Speed Early Science Apps

Jan 6, 2014 |

Researchers working with the Oak Ridge Leadership Computing Facility’s (OLCF’s) Titan supercomputer are making the most of the system’s hybrid design, which pairs traditional CPUs with highly-parallel GPUs. As the fastest computer in the United States, Titan has a max theoretical speed of 27 petaflops, but as a recent OLCF article points out, “Titan is 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…

Titan Runs 15 Petaflop Superconductor Simulation

Nov 15, 2013 |

A research feature at the Oak Ridge Leadership Computing website explores how sheer computing speed and algorithm improvements have put an international team of scientists in the running for this year’s Gordon Bell Prize. The team from ETH Zurich in Switzerland and Oak Ridge National Laboratory (ORNL) have performed simulations of high-temperature superconductors topping 15 Read more…

Cosmic Supercomputing Code Selected as Gordon Bell Finalist

Nov 13, 2013 |

The illuminated compact region shining from the center of an active galaxy is known as an active galactic nucleus (AGN). Active galactic nuclei can produce jets of plasma thousands of light-years long. Consider popular images of galaxies speared by intense light. Many astronomers believe that this explosive energy output is powered by supermassive black holes 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.

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.
