Energy-Aware MPI Communication Library for Power Management?

Feb 9, 2016 |

Can MPI communication runtimes be designed to be energy-aware? Can energy be saved during MPI calls without a loss in performance? These are two questions briefly examined by Dhabaleswar K. (DK) Panda, of The Ohio State University, in a blog post on the Top500 website today (Designing Energy-Aware MPI Communication Library: Opportunities and Challenges). Power, Read more…

Next Steps for NSCI: Seeking to Ensure a Long and Lively Lifespan

Jan 27, 2016 |

It has been six months since the White House released the executive order establishing the National Strategic Computing Initiative (NSCI), the broad interagency research effort seeking to maximize the benefits of high-performance computing (HPC) research, development and deployment across the U.S. public and private sectors. Since then, each of the participating U.S. agencies has prepared Read more…

Exascale Programming: Adapting What We Have Can (and Must) Work

Jan 14, 2016 |

The demands of massive concurrency and increased resilience required for effective exascale computing have led to claims that our existing approach to application programming must be replaced. In this article I argue that disruption is inevitable but will not require new languages or programming environments. Instead disruption will be in application design, introducing new control Read more…

Combustion Simulation in the Exascale Era

Nov 13, 2014 |

One of the many excellent sessions at SC14 will address how the twin technologies of HPC and big data are coalescing to enable major scientific breakthroughs in the field of turbulent combustion. As part of the SC14 Technical Program, Jacqueline H. Chen, a Distinguished Member of Technical Staff at the Combustion Research Facility at Sandia National Laboratories, Read more…

The Exascale Revolution

Oct 23, 2014 |

The post-petascale era is marked by systems with far greater parallelism and architectural complexity. Failing some game-changing innovation, crossing the next 1000x performance barrier will be more challenging than previous efforts. At the 2014 Argonne National Laboratory Training Program on Extreme Scale Computing (ATPESC), held in August, Professor Pete Beckman delivered a talk on “Exascale Architecture Trends” and their impact on the programming and executing of computational Read more…

House Bill Takes Aim at Exascale

Sep 10, 2014 |

The House of Representatives passed an exascale computing support bill Monday highlighting once again the link between next-generation HPC and national competitiveness. The American Super Computing Leadership Act of 2014 (H.R. 2495) seeks to “amend the Department of Energy High-End Computing Revitalization Act of 2004 to improve the high-end computing research and development program of the Department of Read more…

HPC Task Force Publishes Recommendations

Aug 27, 2014 |

The Secretary of Energy Advisory Board (SEAB) Task Force on Next Generation High Performance Computing (HPC), established in December by the Secretary of Energy to review the mission and national capabilities related to next generation high performance computing, has released a “final version” draft report. The Task Force was asked to examine the problems and opportunities Read more…

DOE Highlights Exascale-Focused Research

Aug 7, 2014 |

Every year the Department of Energy Early Career Award provides outstanding scientists who are early in their careers with funding of at least $150,000 per annum over a five-year span. The 2014 funding round, the program’s fifth, awarded research grants to 35 scientists – including 17 from DOE’s national laboratories and 18 from US universities. The program is designed Read more…

Ten Year US Exascale Roadmap Crystalizes

Jan 17, 2014 |

At the tail end of 2013, Congress passed a law directing the Department of Energy to develop exascale computing capability within the next decade in order to meet the objectives of the nuclear stockpile stewardship program. The directive is part of the 2014 National Defense Authorization Act, which President Obama signed into law on December Read more…

DOE Sets Exascale Pricetag

Sep 16, 2013 |

The United States Department of Energy has announced a plan to field an exascale system by 2022, but says in order to meet this objective it will require an investment of $1 billion to $1.4 billion for targeted research and development.
