Fujitsu Targets 100 Petaflops Supercomputing

Aug 12, 2014 |

On Monday at the Hot Chips 26 conference, Fujitsu revealed details about its upcoming SPARC64 XIfx chips, which the company is counting on to reach the 100-petaflops barrier and revitalize its HPC game. Of the top 10 fastest supercomputers on the current TOP500 list, only one is a Fujitsu system. But with the new 32-core Read more…

NERSC Launches Exascale Readiness Program with Intel, Cray

Aug 11, 2014 |

The National Energy Research Scientific Computing Center (NERSC) is collaborating with supercomputing vendors Intel and Cray to prepare for Cori, the Cray XC supercomputer scheduled to be deployed at NERSC in 2016. Named in honor of American biochemist Gerty Cori, the next-generation supercomputer will have a sustained performance that is at least ten times that Read more…

Charming Exascale Power Problems

Jul 30, 2014 |

Power, energy and reliability present major challenges to HPC researchers in their endeavor to build larger machines. As we approach the exascale era, both hardware and software designers need to account for these challenges while optimizing performance. The Parallel Programming Laboratory (PPL) at the University of Illinois at Urbana-Champaign (UIUC) has been actively working on Read more…

Exascale Resilience Turns a Corner

Jul 21, 2014 |

While advancing the field of HPC into the exascale era is beset by many obstacles, resiliency might be the most thorny of all. As the number of cores proliferate so too do the number of incorrect behaviors, threatening not just the operation of the machine, but the validity of the results as well. When you Read more…

Seismic Imaging at the DEEP End

Jun 3, 2014 |

With exascale presenting a much larger challenge than previous exponential computing markers, an integrated, collaborative approach is all the more necessary. While concerted funding efforts for extreme-scale computing came a bit later than many had hoped, there are several international efforts afoot currently, including the European project, DEEP. DEEP, which stands for Dynamical ExaScale Entry Read more…

Europe Launches Ultrascale Computing Initiative

Sep 15, 2014 |

NESUS – or Network for Sustainable Ultrascale Computing – formed earlier this year to study the challenges of ultrascale computing. Launched with about 30 European partner countries, the cross-community initiative has grown to include 39 European countries and six countries from other continents. The goal: to produce a catalogue of open source applications for large-scale complex systems Read more…

NERSC Highlights Exascale-Energy Connection

Sep 11, 2014 |

It’s been almost six months since the National Energy Research Scientific Computing Center (NERSC) formally announced Cori, the new supercomputer set to be installed at the lab in the mid-2016 timeframe. Originally known as NERSC-8, the new machine will sport over 9,300 nodes, equipped with next-generation Knights Landing architecture housed within a Cray XC environment. Each 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…
