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…

Cray Cracks Commercial HPC Code

Jun 20, 2013 |

During a conversation this week with Cray CEO, Peter Ungaro, we learned that the company has managed to extend its reach into the enterprise HPC market quite dramatically–at least in supercomputing business terms. With steady growth into these markets, however, the focus on hardware versus the software side of certain problems for such users is….

Infinera, DANTE Achieve Guinness Record

Aug 30, 2013 |

Earlier this month, Infinera and DANTE (Delivery of Advanced Network Technology to Europe) set a record for fastest provisioning of long haul optical transmission capacity. In less than 20 minutes, the network specialists enabled enough capacity to support the simultaneous streaming of 1.6 million HD films in both directions.

Considerations in HPC Cluster Network Selection

Jul 17, 2013 |

There’s a lot going on in the networks of HPC clusters, and selecting the right network fabric, equipment, and topology is important to ensuring good performance for given applications. A “one size fits all” approach rarely works, and architects will do well to tailor the network to the needs of the application.

Building Supercomputers with Raspberries

May 22, 2013 |

At some point in the not-too-distant future, building powerful, miniature computing systems will be considered a hobby for high schoolers, just as robotics or even Lego-building are today. That could be made possible through recent advancements made with the Raspberry Pi computers.
