Combustion Simulation in the Exascale Era

Nov 13, 2014 |

One of the many excellent sessions at SC14 will address how the twin technologies of HPC and big data are coalescing to enable major scientific breakthroughs in the field of turbulent combustion. As part of the SC14 Technical Program, Jacqueline H. Chen, a Distinguished Member of Technical Staff at the Combustion Research Facility at Sandia National Laboratories, Read more…

Speeding Climate Simulations

Oct 28, 2014 |

As highlighted in a recent issue of DOE Pulse, which features science and technology news from the DOE National Labs, scientists from Pacific Northwest National Laboratory (PNNL) have developed a more efficient way to perform computationally expensive global climate simulations. As climate models become more precise and detailed, the simulation takes more time, putting pressure Read more…

Supercomputing Propels Fusion Science

Sep 29, 2014 |

University of Texas at Austin physicist Wendell Horton has been using the resources of the Texas Advanced Computing Center (TACC) to study the full 3D structure and dynamics of plasma and advance the remarkable science of fusion energy. Fusion science, which seeks to recreate the energy of the stars for use on Earth, has long Read more…

Deconstructing the Hummingbird’s Hover

Sep 2, 2014 |

Ever wonder how a hummingbird is able to hover in mid-air, appearing for a moment to defy the laws of gravity? You’re not alone. Vanderbilt University mechanical engineer Haoxiang Luo accessed the XSEDE’s Lonestar supercomputer to run 3D simulations of a hummingbird flight in an attempt to deconstruct its mysterious powers. Science Writer Jorge Salazar details Luo’s Read more…

Supercomputing Facilitates Breakthrough Cancer Treatment

Aug 25, 2014 |

MD Anderson Cancer Center researchers are relying on a powerful supercomputer to develop a dosing protocol for an MRI-guided radiation therapy for cancer care, called MRI-linac. The Lonestar system at the Texas Advanced Computing Center (TACC) is helping researchers fine-tune the radiation dosing mechanism so that just the right amount of radiation is delivered to the Read more…

Simulations Link Common Brain Disorders

Jul 28, 2014 |

When a coalition of leading researchers from the US and the EU wanted to study brain disorders that involve disturbances of dopaminergic signaling, they turned to the powerful supercomputing resources of the Texas Advanced Computing Center. Using the Extreme Science and Engineering Discovery Environment (XSEDE) cyberinfrastructure and TACC’s Stampede supercomputer, the research team uncovered a link Read more…

Simulations Reveal More About Oldest Known Star

Jul 23, 2014 |

Thanks to the power of supercomputing, scientists from the Universities of Göttingen and Copenhagen now have a better understanding of one of the most ancient stars in the universe. The results of their study were published in the July 21st edition of Astrophysical Journal Letters. The group used high-resolution computer simulations to model the formation of the oldest Read more…

Supercomputers Boost Jet Engine Design

Jun 11, 2014 |

The United States is home to many of the world’s top supercomputers, powerful machines that enable a wide-range of research efforts, from exploring the outer reaches of the universe to enabling faster, quieter and more efficient jet engines. As revealed in a recent report, a group of GE engineers are working with researchers from Arizona Read more…

Mega-Simulations Resolve Starburst Puzzle

May 19, 2014 |

Astrophysicists at the CEA (the French Alternative Energies and Atomic Energy Commission) and CNRS (the French National Center for Scientific Research) have achieved a major breakthrough. Thanks to a set of highly precise supercomputer simulations, the scientists have a much keener understanding of the turbulence that is generated when two galaxies collide. The study used Read more…

Graphene Faces Real-World Limitations

May 5, 2014 |

Graphene is a one-atom-thick layer of carbon that has been hailed as a potential silicon replacement capable of extending the exponential computing advances that modern society has come to depend on. Despite the material’s profile of being strong, flexible, light-weight and a good conductor, there are still a number of challenges that must addressed before Read more…
