Alternative Supercomputing or How to Misuse a Computer

Jul 14, 2016 |

In 2008, the IBM Roadrunner supercomputer broke the petaflops barrier using the power of the heterogeneous Sony Cell Broadband Engine (BE) processor. A year prior, the Cell BE had already made its way into the consumer market as the engine inside the SonyPlaystation 3. The PS3’s accelerated design, Linux-capability and low price point…

COSMOS Team Achieves 100x Speedup on Cosmology Code

Aug 24, 2015 |

One of the most popular sessions at the Intel Developer Forum last week in San Francisco, and certainly one of the most exciting from an HPC perspective, brought together two of the world’s foremost experts in parallel programming to discuss current state-of-the-art methods for leveraging parallelism on processors and coprocessors. The speakers, Intel’s Jim Jeffers and Read more…

CERN Details OpenStack Journey

Nov 4, 2014 |

At the OpenStack Summit in Paris, France, CERN’s Infrastructure Services Manager Tim Bell gave the general session audience an overview of his institution’s experiences moving to OpenStack, which he characterizes as a “cultural and technology transformation.” CERN, the European Organization for Nuclear Research, supports 11,000 physicists from around the world. These scientists use the facilities Read more…

CERN Researchers Explore x86 Alternatives

Oct 28, 2014 |

Energy consumption has become a constraining feature on the growth of computing systems, such that the industry has shifted its focus from pure performance to performance-per-watt. As a result, there is increased interest in newer chip architectures that emphasize energy efficiency. An international group of researchers with ties to CERN are especially concerned with the effect these power constraints Read more…

KAUST Tackles Extreme Event Prediction

Oct 8, 2014 |

Five years ago, shortly after the founding of King Abdullah University of Science and Technology (KAUST) in Thuwal, Saudi Arabia, on the cost of the Red Sea, over 140 millimeters of rain fell over the region in just eight hours, causing over 100 fatalities and $100 million in damages. Flash flooding is most problematic in dry Read more…

Quantum Simulator Yields Strange Light Forms

Sep 16, 2014 |

Scientists have already established that sometimes light behaves like a wave and other times like a particle, but a team of Princeton University researchers has uncovered a new behavior. According to a research brief, the team locked together photons, the basic element of light, so that they are fixed in place, creating in essence solid Read more…

Supercomputing Raises Materials Science to New Heights

Dec 5, 2013 |

Materials science, also called materials engineering, is on the cusp of a new era, emboldened by advances in computational power and quantum mechanics. For some time now, manufacturers have used supercomputers to design better airplanes, cars and other equipment, but now scientists are using similar techniques to develop new materials from scratch. A recent article Read more…

Cosmic Supercomputing Code Selected as Gordon Bell Finalist

Nov 13, 2013 |

The illuminated compact region shining from the center of an active galaxy is known as an active galactic nucleus (AGN). Active galactic nuclei can produce jets of plasma thousands of light-years long. Consider popular images of galaxies speared by intense light. Many astronomers believe that this explosive energy output is powered by supermassive black holes Read more…

Alternatives to x86 for Physics Processing

Nov 11, 2013 |

The global distributed computing system known as the Worldwide LHC Computing Grid (WLCG) brings together resources from more than 150 computing centers in nearly 40 countries. Its mission is to store, distribute and analyze the 25 petabytes of data generated each year by the Large Hadron Collider (LHC), based out of the European Laboratory for Particle Physics (CERN) in Geneva, Switzerland. Read more…

Theoretical Physicists Still Unraveling Big Bang

Oct 1, 2013 |

It’s one of the most essential questions, which speaks to the very fact of our existence: why is the universe made of matter?
