Team EPCC Reveals Secret Weapon Behind Winning Linpack Score

Jul 3, 2014 |

When Team EPCC first announced that they had earned “Highest Linpack” at ISC’14 Student Cluster Competition with a score of 10.14 teraflops, they said to stay tuned for details on their strategy. In a recent blog, the four students, all in the HPC masters program, describe how they achieved the highest-ever Linpack score in the Student Cluster Competition, Read more…

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…

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…

New Benchmark Could Shake Up TOP500 Rankings

Nov 22, 2013 |

The latest TOP500 list of the world’s fastest systems was recently published during SC13 and at first glance not much has changed since the previous list released in June. There was only a single new entrant to the top 10, Piz Daint, a Cray XC30 system installed at the Swiss National Supercomputing Centre (CSCS) in Read more…

LINPACK Creator Sheds Light on Emerging HPC Benchmark

Nov 18, 2013 |

Back in June during the International Supercomputing Conference (ISC), we discussed the need for a potential alternative to the current LINPACK benchmark, which is the sturdy yardstick by which supercomputing might is measured, with its creator, Dr. Jack Dongarra. At that time, he described a new benchmarking effort that is taking shape with the input Read more…

Alternatives Emerge as Linpack Loses Ground

Jun 18, 2013 |

Today at the International Supercomputing Conference in Leipzing, Germany, Jack Dongarra presented on a proposed benchmark that could carry a bit more weight than its older Linpack companion. The high performance conjugate gradient (HPCG) concept takes into account new architectures for new applications, while shedding the floating point….

Titan Didn’t Redo LINPACK for June Top 500 List

Jun 13, 2013 |

Titan, the Cray XK7 at the Oak Ridge National Lab that debuted last fall as the fastest supercomputer in the world with 17.59 petaflops of sustained computing power, will rely on its previous LINPACK test for the upcoming edition of the Top 500 list.

Top Supercomputer Signals Growth of Chinese HPC Industry

Jun 12, 2013 |

At 31 petaflops of sustained LINPACK capacity, the new Chinese Tianhe-2 supercomputer will be the fastest supercomputer in the world when this month’s Top 500 list comes out, as we reported previously in HPCwire.

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.

XPRESS Route to Exascale

Feb 28, 2013 |

<img src=”http://media2.hpcwire.com/hpcwire/abstract_future_150x.jpg” alt=”” width=”95″ height=”83″ />The Center for Research in Extreme Scale Computing (CREST) at Indiana University just got a $1.1 million grant to help further the move to exascale computing. Director Thomas Sterling is using some of the money to bolster UI’s research into highly parallel processing for HPC. He talks to HPCwire about his plans.
