Low Effort Porting Gives Great Scaling of Seismic Code on Numascale Shared Memory Cluster

Aug 4, 2014 |

Numascale and Statoil have initiated a collaboration to optimize OPM for Numascale systems. The original OPM code showed poor scalability even within a single node. With very limited effort, the collaboration was able to obtain almost linear scaling across an entire Numascale system. The configuration enables simulation of entire oilfields with fine grid resolution. The Read more…

This Week in HPC News

Jun 12, 2014 |

If middleware was the theme from last week, then this week is all about hardware, from networking/interconnects (Arista) to systems (HP) to storage (Panasas). Let’s look at little closer at this week’s top stories, starting with HP. HP’s rebooting of the Apollo brand this week was well received. This new family of high performance computing systems Read more…

What Power8 and OpenPOWER Might Mean for HPC

Apr 23, 2014 |

IBM is making a big play in hybrid computing, seeking to marry its POWER8 processors with various kinds of accelerators and high-speed networking and opening up its chip and system software through the OpenPOWER Foundation. At the Open Innovation Summit in San Francisco today, IBM and its foundation partners talked about how their collaboration would deliver Read more…

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…

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.
