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

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

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

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.

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.

Q&A: Jack Wells, Director of Science for the National Center for Computational Sciences

Sep 26, 2011 |

On July 1 Jack Wells became the director of science for the National Center for Computational Sciences (NCCS) at Oak Ridge National Laboratory (ORNL). In this interview he describes his vision for NCCS, some of the cutting-edge applications the center will support, and how the facility will gear up to deliver Titan, a hybrid supercomputer expected to have a peak performance of 10 to 20 petaflops, by early 2013.

Say Hello to the New ADIOS

Sep 12, 2010 |

Last week marked the release of ADIOS 1.2, the latest incarnation of one of computational science’s most effective I/O tools. So far ADIOS has helped researchers make huge strides in fusion, astrophysics and combustion. The new version features some interesting improvements that will doubtless aid researchers in taking full advantage of leading supercomputing platforms.
