NSF Petaflopper Skips Retirement for New Life in Africa

Jul 15, 2014 |

Quick obsolescence goes hand-in-hand with cutting-edge technology. Supercomputing is no exception, and it’s not unusual for these great machines to have lifespans of only a few years. While some retired number crunchers go into storage to perhaps be reconstituted by a museum in a later decade, other systems have happier retirement stories. Such is the Read more…

Remembering Kraken

Jun 5, 2014 |

In supercomputing, it is often the case that top systems are only around for about half a decade. With the breaking of the petascale barrier now fixed in the rearview mirror of 2008, we are starting to see some of those ground-breaking systems reach their retirement age. It happened with Roadrunner, the world’s first petaflopper, not Read more…

Earthquake Simulation Hits Petascale Milestone

Apr 15, 2014 |

German researchers are helping to push back the goalposts on large-scale simulation. Using the the IBM “SuperMUC” high performance computer at the Leibniz Supercomputing Center (LRZ), a cross-disciplinary team of computer scientists, mathematicians and geophysicists successfully scaled an earthquake simulation to more than one petaflop/s, i.e., one quadrillion floating point operations per second. The collaboration included participants Read more…

Accurate Forecasts Tied to Supercomputer Spending

Feb 12, 2014 |

As large swaths of the country are hit by snowstorm after snowstorm and western states battle a decade’s long dry spell with California declaring a drought emergency, weather is on nearly everyone’s mind. For many years now, the populace has relied on powerful supercomputers to forecast the weather, so it may be surprising to learn 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…

Blue Waters: Security at Scale

May 3, 2013 |

For the largest computer systems in the world, keeping IT assets safe presents a unique set of challenges.

The Week in HPC Research

Apr 25, 2013 |

We’ve scoured the journals and conference proceedings to bring you the top research stories of the week. This diverse set of items includes advancements in petascale-era development environments; balancing performance with power efficiency; optimizing computer science instruction; and a possible path to extreme heterogeneity.

Big Red II Colors New Page for Hybrid Systems

Apr 19, 2013 |

Later this month, Indiana University will formally introduce the successor to the Big Red system, the aptly-named, Big Red II. The Cray-crafted and tuned system is 25 times faster than its baby brother (the 4100-core original Big Red from 2006) and sports some notable improvements across its 1,020 nodes. According to Thomas Sterling, there are theoretical lessons that can be applied to…

Revelations on Roadrunner’s Retirement

Apr 4, 2013 |

Following our news report this week on the shuttering of the petaflop pioneer system at Los Alamos National Lab, Roadrunner, we were finally able to snag someone to share on the post-mortem plans for the system, not to mention what some of the considerations were for housing a unique architecture like….

Sequoia Goes Core-AZY

Mar 20, 2013 |

LLNL researchers have successfully harnessed all 1,572,864 of Sequoia’s cores for one impressive simulation.
