Space Weather Forecasting Clears Another Hurdle

Mar 3, 2016 |

Space weather forecasting might not have a dedicated segment on the evening news, but the disruptive power looming above the Earth’s atmosphere cannot be underestimated. One form of space weather in particular, the coronal mass ejection (CME), has the potential to take down satellites and power grids on a national and even international scale. A coronal Read more…

Realistic Simulator Replicates Combat Injuries

Feb 2, 2016 |

A multi-disciplinary team of researchers at the University of California Los Angeles (UCLA) have developed a detailed computer model of an injured human leg that includes the complex workings of blood flow. The aim of the project, sponsored by the Office of Naval Research, is to provide combat medics with a realistic training tool to enable them Read more…

Accelerating HPC in Formula One

Nov 3, 2015 |

The Formula One racing community has embraced HPC as an essential part of its workflow to build ever-speedier race cars, but suggestions that CFD should obviate the need for wind tunnel testing continue to draw heated commentary. One of the aerodynamics software vendors that supports this move is Exa Corporation. The Burlington, Mass.-headquartered company serves the Read more…

‘ASCI’ Turns 20; David Turek Offers IBM Retrospective

Oct 21, 2015 |

Twenty years ago President Bill Clinton announced that the United States would maintain its U.S. nuclear arsenal without nuclear explosive testing. The challenge, of course, was how to actually carry out such a daunting task. The instruments were the tremendously successful Stockpile Stewardship Program (SSP) and Accelerated Strategic Computing Initiative which together drove much of Read more…

Formula One Contemplates CFD-Only Future

Oct 7, 2015 |

Digital design has become central to Formula 1 racing, but don’t rule out wind tunnels just yet. That is the message coming out of a recent F1 Strategy Group meeting. The group comprises the sport’s governing body FIA, the sport’s commercial arm run by Bernie Ecclestone and the top six teams. The stakeholders responsible for Read more…

The Case for ‘Inexactness’ in Supercomputing

Oct 6, 2015 |

Scientific computing must become less rigid and power hungry as researchers seek new ways to model and understand the real world, a climatologist argues. In a commentary published this week in the journal Nature, climate researcher Tim Palmer asserted that “we should question whether all scientific computations need to be performed deterministically — that is, Read more…

U of Michigan Project Combines Modeling and Machine Learning

Sep 10, 2015 |

Although we’ve yet to settle on a term for it, the convergence of HPC and a new generation of big data technologies is set to transform science. The compute-plus-data mantra reaches all the way to the White House with President Obama’s National Strategic Computing Initiative calling for useful exascale computing and sophisticated data capabilities that serve the Read more…

Argonne Team Tackles Uncertainties in Engine Simulation

Aug 27, 2015 |

As we head deeper into the digital age, computers appropriate an ever greater share of the work of designing and testing physical systems, spanning the gamut from nuclear components to personal care products. Engine design is another important, but very complex, application that is benefiting from computational modeling. To optimize the performance of combustion engines, chemical models are incorporated into computer simulations. Read more…

IDC: The Changing Face of HPC

Jul 16, 2015 |

At IDC’s annual ISC breakfast there was a good deal more than market update numbers although there were plenty of those: “We try to track every server sold, every quarter, worldwide,” said Earl Joseph, IDC program vice president and executive director HPC User Forum. Perhaps more revealing and as important this year was IDC’s unveiling Read more…

Digital Prototyping a Mercedes

Jul 14, 2015 |

ISC 2015’s emphasis on HPC use in industry was reflected in the choice of Monday’s opening keynote speaker, Jürgen Kohler, senior manager, NVH (noise, vibration, and harshness) CAE & Vehicle Concepts, Mercedes-Benz Cars Development. Kohler presented a fascinating overview of the evolution of the auto industry’s use of HPC-based modeling and simulation. (Did you know Read more…
