The Surprising Science Behind Everyday Products

Aug 27, 2014 |

One doesn’t normally associate their favorite shampoo or laundry detergent with science, let alone multi-million dollar supercomputers, but in today’s modern world many well-known consumer goods are the products of extensive R&D. By using large-scale computational modeling to facilitate advanced product design, manufacturers can improve customer satisfaction and minimize costly design flaws. A recent feature article on the 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…

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 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…

ADIOS Team Wins Award

Sep 4, 2013 |

In this fast-moving field, certain HPC software projects manage to both stand out and stand the test of time, and that’s the case with ADIOS, an open-source middleware developed to handle big data workloads…

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.

As Supercomputers Approach Exascale, Experts Wrestle with Big Data

Jul 21, 2011 |

The current generation of petascale supercomputers are generating enormous quantities of data, and creating unprecedented challenges in managing it. The next generation of multi-petaflop, and eventually exaflop supercomputers, will take these challenges to the next level. Galen Shipman, who heads the Technology Integration group at the Oak Ridge Leadership Computing Facility (OLCF) talks about the data management technologies being employed at OLCF today and what will be needed to support their future exascale machines.

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.
