Focus Sharpens on New HPC Benchmark

Jan 6, 2014 |

Over the last few years in particular, discussions about the limitations of the current measurement for the Top500, the LINPACK benchmark, have echoed louder. The result of these lines of questioning have led to a new benchmarking possibility–one that takes real world application needs and current architectural and system design trends into greater account. LINPACK Read more…

Air-Cooled Supercomputer Is Among World’s Greenest

Dec 9, 2013 |

Unlike this November’s TOP500 list, which had very little churn in the top 10 (only one new system, Piz Daint, squeezed into the elite club) the most recent Green500 list’s upper echelon was filled with nothing but newcomers. While most are liquid-cooled, taking second place is an energy-efficient air-cooled supercomputer from the University of Cambridge, Read more…

SC13 in Review: The Week’s Top Newsmakers

Nov 28, 2013 |

This year at SC13 we counted over 100 HPC-specific announcements that hit the wires over the course of the week, many of which were from vendors, organizations and users that we were within a short walk across the show floor in Denver. We wanted to point to some of the key newsmakers during the show, Read more…

NVIDIA Kepler Parts Top Green500

Nov 22, 2013 |

Twice a year, in step with the biannual TOP500 list, the Green500 list ranks the most powerful systems in the world based on energy-efficiency. Published Wednesday evening at SC13, this year’s Green500 list continues a trend from previous years, the rise of heterogenous supercomputing. The latest list shows that the top 10 greenest systems are Read more…

Top 500 Interconnect History Highlights Ethernet Trends

Nov 19, 2013 |

As we related earlier when the news of the Top 500 rankings broke this morning, this November’s SC list was a rather static one in terms of the top ten systems. While this isn’t entirely unexpected since it was not likely anyone would usurp China’s dominance and since there were no big processor movements in Read more…

China’s Exascale Ambitions

Oct 11, 2013 |

“Beware the sleeping dragon. For when she awakes the Earth will shake.” — Winston Churchill, speaking about China For two decades, TOP500.org has published a biannual list of the world’s fastest computing machines. For the first 17 years, the competition for the number one spot was a back-and-forth match between the United States and Japan. Read more…

Linux Foundation Maps Top500 Run

Jul 30, 2013 |

This week the Linux Foundation released a special report about its role over the last twenty years of the Top500, pointing to some significant trends that helped it switch places with Unix (which once had a 96% share of the list) in roughly a one-decade timeframe. For instance, there are a few….

A Conversation with Dr. Hans Meuer and Dr. Horst Gietl

Apr 22, 2013 |

Gearing up for ISC’13, contributor Miha Ahronovitz examines where HPC has been and where it’s headed. In this in-depth interview, Drs. Hans Meuer and Horst Gietl recount the origins of the TOP500 list and wax prophetic on the future of supercomputing, including the peril and promise of parallel programming as well as the long-term shift away from compute centrism.

Yellowstone Helps Predict Air Pollution

Mar 28, 2013 |

The Yellowstone supercomputer has a 1.5-petaflop I-data plex system at peak. The machine was first tasked with 11 compute-intensive projects as part of the Accelerated Scientific Discovery (ASD) initiative.

World’s Fastest Supercomputer Hits Speed Bump

Feb 27, 2013 |

When it comes to Titan’s final acceptance testing, ONRL says not so fast.
