TOP500 Reanalysis Shows ‘Nothing Wrong with Moore’s Law’

Nov 20, 2015 |

In Tuesday night’s TOP500 session, list co-creator and co-author Erich Strohmaier brought perspective to what could at first appear to be a land grab of unprecedented scale by China, when he shared that many of these new entrants were mid-lifecycle systems that were just now being benchmarked. But what is likely to be even more Read more…

TOP500 Trends That Cannot Be Ignored

Nov 16, 2015 |

The 46th edition of the twice-yearly TOP500 list is hot off the presses and while there’s not much to break the monotony at the peak, this is in many ways a pivotal edition of the list in that it makes it hard to dismiss two trends in particular: China’s ascendance and flattening growth trajectories. But before we Read more…

LINPACK’s ‘Companion Metric’ Gains Traction

Jul 15, 2015 |

The TOP500 organizers published their 45th twice-yearly list this week in tandem with ISC 2015 in Frankfurt, Germany. What is becoming increasingly clear, as our analysis piece covered and as many in the community have also pointed out, is that the salad days of “better-than-Moore’s” performance growth hit an inflection point in 2008. We went into the Read more…

Architectural Surprises Underpin New HPC Benchmark Results

Dec 1, 2014 |

One of the most heated debates in supercomputing circles over the last several years has been around the continued validity of the current basis of the Top 500 ranking of the fastest systems in the world, the high performance LINPACK (HPL) benchmark. Out of these many criticisms, one of the founders of the original LINPACK Read more…

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….
