Burst Buffers Flash Exascale Potential

May 1, 2014 |

For any large-scale datacenter, be it a scientific supercomputer or hyperscale web farm, the constant battles of “defensive I/O” and “offensive I/O” take their toll on overall efficiency and productivity. From checkpointing to pushing performance on long-running applications, one set of technologies is pushing its way onto the frontlines. The “burst buffer” concept, as Los Read more…

Emerging System Sets Stage for Exascale Science

Apr 29, 2014 |

Today we welcome a new large-scale system into the high performance computing fold with the formal announcement of Cori, a new supercomputer set to be installed at NERSC in the mid-2016 timeframe. Known in its RFP stages as NERSC-8, the new machine will sport over 9,300 nodes, featuring the next-generation Knights Landing architecture housed within Read more…

‘Edison’ Helps Reinvent the Light Bulb

Apr 9, 2014 |

Today’s consumers have an array of lighting options to select from, giving them the light they want while saving energy and money. In addition to the standard incandescent bulb that’s been around since Thomas Edison invented it about 130 years ago, there are energy-efficient halogen incandescents, compact florescent lamps (CFLs) and a new breed of Read more…

‘Edison’ Lights Up Research at NERSC

Jan 31, 2014 |

The National Energy Research Scientific Computing (NERSC) Center, located at Lawrence Berkeley National Laboratory, has taken acceptance of “Edison,” a Cray XC30 supercomputer named in honor of famed American inventor Thomas Alva Edison. The important milestone occurs just as NERSC is commemorating 40 years of scientific advances, prompting NERSC Director Sudip Dosanjh to comment: “As Read more…

NERSC Supercomputer Boosts Energy Research

Dec 4, 2013 |

Scientists at Oak Ridge National Laboratory (ORNL) are using DOE supercomputers and a neutron scanning technique to develop more efficient methods of extracting gas and oil from shale. Using the systems at the Department of Energy’s National Energy Research Supercomputing Center (NERSC) – supercomputing resources include Hopper and Edison – the researchers are studying the Read more…

Supercomputer Bolsters Innovative Stroke Research

Sep 25, 2013 |

A group of researchers from UC Berkeley and UCSD used NERSC supercomputing resources to model the efficacy of microbubbles and high-intensity ultrasound for breaking up stroke-causing clots.

Supercomputing Enables Climate Time Machine

Sep 23, 2013 |

Climate scientists use DOE supercomputers to provide independent confirmation of global land warming since 1901 – further evidence of anthropogenic global climate change. Project shows “predictions” not only possible, but also highly accurate…

DOE Supercomputer Hack Results in Guilty Plea

Aug 30, 2013 |

A 24-year old Pennsylvania man, Andrew James Miller, pleaded guilty to charges of hacking into Department of Energy supercomputers and attempting to sell stolen access credentials. Miller offered to sell an undercover FBI agent root access to NERSC systems for the sum of $50,000.

Researchers Squeeze Record I/O from Hopper

Jun 5, 2013 |

Researchers with the Lawrence Berkeley National Laboratory and Cray squeezed more I/O from the NERSC Cray XE6 “Hopper” supercomputer than ever before in a plasma physics simulation involving more than a trillion particles. The work paved the way for even bigger, exascale HDF5 workloads in the future, and yielded a scientific discovery as a bonus.

“No Exascale for You!” An Interview with Berkeley Lab’s Horst Simon

May 15, 2013 |

Although Horst Simon was named Deputy Director of Lawrence Berkeley National Laboratory, he maintains his strong ties to the scientific computing community as an editor of the TOP500 list and as an invited speaker at conferences.
