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…

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…

SC13 Research Highlight: There Goes the Performance Neighborhood…

Nov 16, 2013 |

Message passing can take up a significant fraction of the run time for massively parallel science simulation codes. Consistently high message passing rates are required for these codes to deliver good performance. At Supercomputing 2013 (SC13), our research team from Lawrence Livermore (LLNL) will present the results of our study that show that run-to-run variability Read more…

Infiniband Snaps Up Strong Super Share

Jul 8, 2013 |

Infiniband carried a slight majority of the Top 500 share this year at ISC, a trend that Mellanox says will continue, both in HPC and beyond. We discussed IB’s reach and efficiencies with the company’s Gilad Shainer to better understand where Ethernet and Infinband are…

PSC Tests New Shared Memory Waters

Jul 1, 2013 |

The Pittsburgh Supercomputer Center recently announced a new step in its path to discover new routes to solving memory and I/O problems for data-intensive applications. While they already have a stable of systems that take new approaches to shared memory and have looked to software-based solutions as alternatives, they have now turned to Numascale to dip their toe in the hardware-based…
