Simulating Combustion at Exascale: a Q&A with ISC Keynoter Jacqueline Chen

Mar 14, 2016 |

At the 2016 ISC High Performance conference this June, distinguished Sandia computational combustion scientist Jacqueline H. Chen will deliver a keynote highlighting the latest advances in combustion modeling and simulation. In this interesting and informative Q&A, Chen describes the challenges and opportunities involved in preparing combustion codes for exascale machines.

Biomedical Simulation at PSC Gets Major Performance Boost with Anton 2

Feb 5, 2016 |

Simulating even small biological systems has long proven computationally difficult. Practically speaking, data-driven bioinformatics such as DNA sequence analysis has progressed more rapidly. Development of Anton 1, the ASIC-based supercomputer specifically designed for simulating molecular dynamics by D. E. Shaw Research (DESRES) in 2008, was a major advance. In 2010 DESRES provided an Anton machine Read more…

Unlocking the Mysteries of Space

Jun 16, 2015 |

Some of the most powerful supercomputers in the world are helping NASA scientists reveal the mysteries of the universe. The intensive discovery process would not be possible without the modeling and simulation capabilities of high-performance computers, like Pleiades, which is located at the NASA Advanced Supercomputing (NAS) facility at Ames Research Center, and Titan, the fastest Read more…

DARPA Seeks New Computing Paradigms

Mar 26, 2015 |

May you live in interesting times, cautions the age-old proverb. As computing chips face the fundamental limitations of miniaturization, it is sure to be interesting times, indeed. One of the most pressing issues facing the scientific community is the inability of today’s best computers to process the large-scale simulations needed for understanding complex physical systems. “Over Read more…

Cornell Levies Blue Waters to Curb Flooding

Feb 18, 2015 |

With the steady progression of climate change, the rate of flooding across the globe is only expected to rise. But according to a new study from Cornell University, our first line of defense ­– a series of weather satellites situated hundreds of miles above the Earth’s surface – are in need of some serious overhaul. Read more…

GPU-Powered Simulations Advance Heart Research

Feb 5, 2015 |

With heart disease topping the list as the number one cause of death worldwide, heart rhythms disorders, or arrhythmias, are worthy of serious concern. Hoping to halt the devastating effects of the disorder is the Victor Chang Cardiac Research Institute (VCCRI) in Darlinghurst, Australia, where researchers are using a supercomputer to better understand, diagnose and Read more…

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…
