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…

SC14 Technical Program Preview

Jul 29, 2014 |

July has been rather quiet in the HPC space, but what better time to start looking ahead and preparing for the busy fall ahead, including the preeminent annual HPC event: SC14. Attendees won’t flock to this event until November 16, but SC planners are busy getting everything into place, including the core event offering: the Read more…

Getting to Exascale

Jul 24, 2014 |

As the exascale barrier draws ever closer, experts around the world turn their attention to enabling this major advance. Providing a truly deep dive into the subject matter is the Harvard School of Engineering and Applied Science. The institution’s summer 2014 issue of “Topics” takes a hard look at the way that supercomputing is progressing. In 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…

Manufacturing Exascale

Jul 7, 2014 |

Exascale systems are certainly the current buzz in high performance computing. While theoretical projections suggest the possibility to have an exascale system by 2018, reality tells us that a usable supercomputer of that size will require at least few years into the next decade. Simply adopting the current approach – more of the same but Read more…

Senate Legislation Prioritizes Science, HPC

Jun 18, 2014 |

The US Senate Appropriations Subcommittee on Energy and Water Development is proposing legislation that would boost funding for scientific discovery and next-generation computing. The panel, chaired by Senator Dianne Feinstein (D-CA), approved federal funding legislation that would provide $5.086 billion for the Department of Energy’s (DOE’s) Office of Science for the 2015 fiscal year that 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…

LANL Demos Extreme Scale Indexing

Jun 3, 2014 |

An HPC middleware project currently underway at Los Alamos National Laboratory has reached a significant milestone. The new supercomputing tool, developed as part of the Multi-dimensional Hashed Indexed Middleware (MDHIM) project, made 1,782,105,749 key/value inserts per second into a globally-ordered key space on Los Alamos National Laboratory’s Moonlight supercomputer. The demonstration showcases the potential of MDHIM Read more…

Evolving Exascale Applications Via Graphs

Apr 29, 2014 |

There is little point to building expensive exaflop-class computing machines if applications are not available to exploit the tremendous scale and parallelism. Consider that exaflop-class supercomputers will exhibit billion-way parallelism, and that calculations will be restricted by energy consumption, heat generation, and data movement. This level of complexity is sufficient to stymy application development, which Read more…

Emerging System Sets Stage for Exascale Science

Apr 29, 2014 |

Today we welcome a new large-scale system into the high performance computing fold with the formal announcement of Cori, a new supercomputer set to be installed at NERSC in the mid-2016 timeframe. Known in its RFP stages as NERSC-8, the new machine will sport over 9,300 nodes, featuring the next-generation Knights Landing architecture housed within Read more…
