Titan Simulation Reveals New Details of Fissioning Plutonium

Jul 26, 2016 |

In a first study of its kind, a team led by the University of Washington’s Aurel Bulgac captured the real-time dynamics of a fissioning plutonium-240 nucleus by simulating the process on the Titan supercomputer at the Oak Ridge Leadership Computing Facility (OLCF), a US Department of Energy (DOE) Office of Science User Facility. To create Read more…

Titan Sheds Light on Universe’s Second Flicker

Mar 9, 2016 |

Right after the Big Bang the universe was filled with hot, ionized hydrogen (H) and helium (He) gas, a bright torch if you will. By 400,000 years later the flame had dimmed as the gas de-ionized (atoms recaptured electrons) and radiation shifted to ‘invisible’ wavelengths. So started the Cosmic Dark Ages. Now a group of Read more…

Titan Helps Researchers Explore Explosive Star Scenarios

Dec 8, 2015 |

A team led by Michael Zingale of Stony Brook University is exploring the physics of Type Ia supernovas using the Titan supercomputer at the US Department of Energy’s (DOE’s) Oak Ridge National Laboratory. Titan is the flagship machine of the Oak Ridge Leadership Computing Facility (OLCF), a DOE Office of Science User Facility located at Read more…

ORNL Shows Off Titan on Periscope

Nov 5, 2015 |

If you need a reason to join the Periscope craze, how about getting an inside look at the fastest supercomputer in the United States? Today staff at the Oak Ridge Leadership Computing Facility (OLCF), the DOE Office of Science user facility at Oak Ridge National Laboratory (ORNL) took the Periscope audience on a tour of Titan, Read more…

Unlocking the Mysteries of Space

Jun 16, 2015 |

Some of the most powerful supercomputers in the world are helping NASA scientists reveal the mysteries of the universe. The intensive discovery process would not be possible without the modeling and simulation capabilities of high-performance computers, like Pleiades, which is located at the NASA Advanced Supercomputing (NAS) facility at Ames Research Center, and Titan, the fastest Read more…

Application Readiness at the DOE, Part II: NERSC Preps for Cori

Apr 17, 2015 |

In our second video feature from the HPC User Forum panel, “The Who-What-When of Getting Applications Ready to Run On, And Across, Office of Science Next-Gen Leadership Computing Systems,” we learn more about the goals and challenges associated with getting science applications ready for the coming crop of Department of Energy (DOE) supercomputers, which in addition to being five-to-seven times faster than Read more…

Hybrid Test Clusters Forge Path to ‘Summit’

Mar 12, 2015 |

The Department of Energy (DOE) pre-exascale supercomputer Summit is not scheduled to go live until early 2018, yet support staff at the Oak Ridge Leadership Computing Facility (OLCF) have been preparing for Summit’s arrival since the contract was announced last November. The degree of planning is only natural considering the expense and resources involved in standing Read more…

Titan Enables Next-Gen Nuclear Models

Jun 5, 2014 |

One of the main research areas for the Titan supercomputer, the elite Cray system installed at Oak Ridge Leadership Computing Facility, is energy, and in particular nuclear energy. At this point, about 20 percent of America’s energy is produced by nuclear power. Many experts say that increasing this percentage is key to meeting our nation’s growing Read more…

Titan Moves Full Steam Ahead

Jun 2, 2014 |

News being what it is, there’s a tendency to focus on what went wrong rather than what went right, but according to an update from the Oak Ridge Leadership Computing Facility, the early glitches associated with their Cray XK7 “Titan” system have been ironed out. Representatives with OLCF say that Titan “has overcome a challenging launch and Read more…

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.
