Energy Giant Vestas Harnesses HPC and Analytics for Renewables

Sep 21, 2016 |

The energy industry was an early adopter of supercomputing; in fact, energy companies have the most powerful supercomputers in the commercial world. And although HPC in the energy sector is almost exclusively associated with seismic workloads, it also plays a critical role with renewables as well, reflecting the growing maturity of that vertical. The largest Read more…

Latest DDN Launch Fills out its WOS Object Storage Line

Sep 13, 2016 |

DataDirect Networks (DDN) today introduced a third member to its WOS object storage product line, the WOS 8460, aimed at active archive and collaboration use cases. Object storage, once mainly restricted to ‘cold’ archives for large quantities of unstructured data – think content delivery networks (CDN) used in conjunction with the web – has been slowly expanding its footprint into other application areas. The new DDN product fills out the company’s object storage portfolio and is positioned between DDN’s WOS 9660 offering, intended more for traditional ‘cold’ archives, and WOS 7000, which is well suited for embedded applications such as use with S3.

Why Cross-Accelerator Performance Profiling is a Challenge

Aug 17, 2016 |

High performance computing (HPC) systems are comprised of multiple compute nodes interconnected by a network. Previously these nodes were composed solely of multi-core processors, but nowadays they also include many-core processors, which are called accelerators. Although accelerators provide higher levels of parallelism, their inclusion in HPC systems results in more complex system designs and increases Read more…

DARPA Ramps Up Spectrum Challenge with Information Days

Aug 4, 2016 |

Next week, the DARPA-sponsored Spectrum Collaboration Challenge (SC2) to invent a better way to dynamically carve up and use of electromagnetic spectrum will hold its first information days. The information sessions are among the first concrete steps in what will be a long haul for teams – the winning designs aren’t expected until lat 2019. Read more…

IBM Phase Change Device Shows Promise for Emerging AI Apps

Aug 3, 2016 |

IBM Research today announced a significant advance in phase-change memristive technology – based on chalcogenide-based phase-change materials – that IBM says has the potential to achieve much higher neuronal circuit densities and lower power in neuromorphic computing. Also, for the first time, researchers demonstrated randomly spiking neurons based on the technology and were able to Read more…

MPI Is Not Perfect … Yet

Aug 3, 2016 |

The Message Passing Interface (MPI) is the standard definition of a communication API that has underpinned traditional HPC for decades. The message passing programming represents distributed-memory hardware architectures using processes that send messages to each other. When first standardised in 1993-4, MPI was a major step forward from the many proprietary, system-dependent, and semantically different message-passing libraries that came before it.

D.C. Workshop Strives to Keep NSCI Flame Burning and Growing

Aug 1, 2016 |

Last Friday, almost exactly one year after President Obama’s Executive Order establishing the National Strategic Computing Initiative (NSCI), the Office of Science and Technology Policy held a workshop in Washington D.C. ostensibly to celebrate NSCI accomplishments so far – and there are many. Just as important, the meeting sought to (re)energize NSCI’s diverse stakeholders, many Read more…

Report Addresses the Perils of Dark Silicon

Jul 21, 2016 |

Dark silicon refers to the processing potential that’s lost when thermal constraints disallow full CPU utilization. The gap between transistor scaling and voltage scaling combined with tighter integration of components (multicore, SoCs) has power density ramifications that are of particular concern for embedded computing, but high-performance computing faces similar “dark power” challenges. Bringing attention to this issue and exploring common solutions was the goal of the Dagstuhl Seminar 16052, “Dark Silicon: From Embedded to HPC Systems.”

Los Alamos Researcher Honored for HPC Storage Leadership

Jul 21, 2016 |

Gary Grider, deputy division leader of the High Performance Computing (HPC) Division at Los Alamos National Laboratory, was awarded 2015 Richard P. Feynman Innovation Prize at a ceremony last week for his national leadership in developing cutting-edge HPC strategies and his innovative business partnerships. Grider is a leader in the HPC storage community and holds Read more…

Lengau: Global Grand Challenges Through an African Lens

Jul 19, 2016 |

South African Council for Scientific and Industrial Research (CSIR) Program Director Kagiso Chikane recently welcomed 100 guests to the Centre for High Performance Computing (CHPC) in Cape Town for the dedication of the fastest computer on the African continent. “Lengau,” which means “Cheetah” in the African Setswana language, ranked 121 on the June TOP500 list of the world’s fastest supercomputers.
