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.

Briefing Alert: SoftBank will Purchase ARM Ltd for $32B

Jul 18, 2016 |

ARM Ltd has agreed to be bought by Japanese technology company SoftBank for $32B according to both companies. ARM-based chips are already dominant players in the mobile computing market and recently efforts to push ARM processors into servers, including HPC, have gained momentum. For example, Japan’s next flagship supercomputer, the post K Computer, will be Read more…

Life in a Drop: Ohio Supercomputer Helps Prove Hydration’s Role in Protein Folding

Jul 14, 2016 |

It’s perhaps fitting that in the middle of the summer, when water management is a common challenge, that a paper in the Proceeding of the National Academy of Sciences (PNAS) offers more proof that life as we know it can’t occur without water. Using Ohio Supercomputing Center resources, researchers have shown the critical role water plays in actively guiding protein folding and movement. “For a long time, scientists have been trying to figure out how water interacts with proteins…

ISC Workshop Tackles the Co-development Challenge

Jul 12, 2016 |

The long percolating discussion over ‘co-development’ and how best it should be undertaken has gained new urgency in the race towards exascale computing. At a workshop held at ISC2016 last month – Form Follows Function: Do algorithms and applications challenge or drag behind the hardware evolution? – several distinguished panelists offered varying viewpoints. Yesterday, session organizer Tobias Weinzierl posted a summary synopsis of the workshop discussion on arXiv.org. Weinzierl (Durham University) and co-organizer Michael Bader (Technische Universität München) are active participants in the ExaHyPE project (An Exascale Hyperbolic PDE (partial differential equation) Engine, funded by EU’s Horizon 2020 program).

A Celebration of Women in HPC

Jul 7, 2016 |

Why are there not more women in HPC? This was the simple question that led to the formation of the Women in HPC (WHPC) network nearly three years ago. Under the direction of founder Dr. Toni Collis of the Edinburgh Parallel Computing Centre (EPCC), the organization has been gaining momentum and making a name for itself since its inaugural Women in HPC workshop at SC14. At ISC 2016 in Frankfurt, Germany, WHPC expanded its program to three events: its fourth international Women in High Performance Computing (WHPC) workshop; a BOF on women in HPC; and a networking luncheon. The BOF (June 21) and the workshop (June 23) shared the theme of addressing the gender gap in HPC. Women in HPC has found that women make up between 5 and 17 percent of HPC users, researchers and conference attendees.

OLCF Researchers Scale R to Tackle Big Science Data Sets

Jul 6, 2016 |

Sometimes lost in the discussion around big data is the fact that big science has long generated huge data sets. “In fact, large-scale simulations that run on leadership-class supercomputers work at such high speeds and resolution that they generate unprecedented amounts of data. The size of these datasets—ranging from a few gigabytes to hundreds of Read more…

PNNL’s CENATE Quickly Winning Industry Support and Collaboration

Jul 6, 2016 |

Getting to the root of how things work has informed and progressed all aspects of scientific discovery. As computers and applications grow in complexity, seemingly poised to enter a new phase beyond the limits of Moore’s Law and CMOS technology, enlightening how they work best is paramount. With new resources from a growing list of industry partners, the Center for Advanced Technology Evaluation – known as CENATE – a computing proving ground at Pacific Northwest National Laboratory supported by the U.S. Department of Energy’s Office of Advanced Scientific Computing Research, is rapidly expanding its capabilities to assist the high-performance computing community.

Trinity Wrestles with Knights Landing Programming Challenge with COE

Jul 5, 2016 |

Seventy-one years ago, on July 16, 1945, an incredible explosion lit up the New Mexico night sky. This was the Trinity Test, the world’s first nuclear detonation, and it marked the beginning of the Nuclear Age. It also ushered in the age of supercomputers, which essentially began with weapons science at Los Alamos National Laboratory (LANL). Now a new Trinity, a next generation Cray XC supercomputer is about to take center stage to help the national security labs achieve their primary mission – to provide the nation with a safe, secure and effective nuclear deterrent.
