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…

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….

Top 500 Results Reveal Global Acceleration, Balance Shift

Jun 17, 2013 |

The Top 500 list of the world’s fastest computers has just been announced. Not surprisingly, since it’s been reported on prior to the official announcement, the Chinese Tianhe-2 system tops the list. And that is an understatement. We talk with Jack Dongarra, Horst Simon, Hans Meuer and others from the….

New Tome Tells Modern History of Supercomputing

May 6, 2013 |

A new book for the shelves of supercomputing aficionados has emerged, which covers a rather impressive swath of topic areas—from analyses of current top systems like Sequoia and…
