Supercomputers Help Capture Rare Black Hole Events

Apr 16, 2014 |

When an orbiting star gets too close to a galaxy’s central supermassive black hole, it eventually gets torn apart by the immense gravitational forces, a phenomenon known as a “tidal disruption.” Although black holes cannot be seen directly, since their dense mass means that not even light can escape, the inhaled star produces a brief Read more…

Viglen Gives UK Science Facility JASMIN £4 Million Makeover

Apr 10, 2014 |

British systems integrator Viglen has won a £4 million contract to outfit JASMIN, a UK-based environmental scientific data analysis and simulation facility, with petascale-level data processing and storage capabilities. The contract calls for the design, supply and installation of a turnkey integrated HPC computing, storage and network solution at the site, which is run by Read more…

Instrument Science Preps for Exascale Era

Apr 3, 2014 |

The Big Data and Extreme-scale Computing (BDEC) workshop that took place in February in Fukuoka, Japan, brought together luminaries from industry, academia and government to discuss today’s big data challenges in the context of extreme-scale computing. Attendees to this invitation-only event include some of the world’s foremost experts on algorithms, computer system architecture, operating systems, Read more…

Supercomputers Advance Understanding of Black Holes

Mar 3, 2014 |

Black holes, so fascinating to star-gazers of the professional and backyard variety, are definitely not empty as their name might imply. Quite to the contrary, they are exceedingly dense. According to NASA, these astronomic objects comprise a great amount of matter packed into a very small zone. It’s like a star ten times more massive Read more…

DOE Supercomputing Aims for 100-200 PFLOPS in 2017

Jan 16, 2014 |

In a recent post on Atomic City Underground, Frank Munger examines the progress made by the CORAL project, which HPCwire detailed last year. CORAL – which stands for Collaboration of Oak Ridge, Argonne and Livermore – formed so that Oak Ridge National Laboratory (ORNL), Argonne (ANL) and Lawrence Livermore (LLNL) – could combine forces when Read more…

Supercomputing Fundamental to SKA Project

Dec 12, 2013 |

First proposed in 1991, the Square-Kilometer Array (SKA) project seeks to build and operate the largest radio telescope in the world to peer into the deepest recesses of the cosmos. Instead of seeing light waves, the SKA telescope will turn radio waves into images. The array will be 50 times more sensitive than any other Read more…

SC13 Talk Pushes HPC in New Educational Directions

Nov 19, 2013 |

According to Dr. Thom Dunning from University of Illinois at Urbana-Champaign, science and engineering research has been revolutionized by computation but, to date computing has largely been used to organize, prepare for and disseminate courses. Dunning says that “The potential of using these technologies to teach students the fundamental principles of a subject through authentic Read more…

SC13 Research Highlight: Extreme Scale Plasma Turbulence Simulation

Nov 16, 2013 |

As the global energy economy makes the transition from fossil fuels toward cleaner alternatives, fusion becomes an attractive potential solution for satisfying the growing needs. Fusion energy, which is the power source for the sun, can be generated on earth, for example, in magnetically-confined laboratory plasma experiments (called “tokamaks”) when the isotopes of hydrogen (e.g., Read more…

SC13 Research Highlight: Petascale DNS of Turbulent Channel Flow

Nov 15, 2013 |

Whether a car on the highway, a plane flying through the air, or a ship in the ocean, all of these transport systems move through fluids. And in nearly all cases, the fluid flowing around these vehicles will be turbulent. With over 20% of global energy consumption expended on transportation, the large fraction of the Read more…

Hurricane Force Supercomputing: Petascale Simulations of Sandy

Nov 14, 2013 |

The devastation incurred by the landfall of Hurricane Sandy on the northeast coast of the United States just over one year ago exemplifies the need for further advances in accuracy and reliability in numerical weather prediction. High resolution numerical weather simulations carried out on hundreds of thousands of processors on the largest supercomputers, Blue Waters in this case, are providing these very insights.
