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…

Mining for Efficiencies Post Moore’s Law

Apr 17, 2014 |

Computers are so much more than the interface most Web-connected humans interact with on a daily basis. While many of us take for granted the thousands of instructions that must be communicated across a vast array of hardware and software, this is not the case for the computer scientists and engineers working to shave nanoseconds Read more…

Prioritizing Data in the Age of Exascale

Apr 14, 2014 |

By now, most HPCers and the surrounding community are aware that data movement poses one of the most fundamental challenges to post-petascale computing. Around the world exascale-directed projects are attempting to maximize system speeds while minimizing energy costs. In the US, for example, exascale targets have peak performance increasing by three orders of magnitude while Read more…

Russia, India Take Aim at China’s FLOPS Lead

Apr 9, 2014 |

The race to build the world’s fastest supercomputer – and possibly even the first exascale-class system – just got more interesting. Russia and India are considering an alliance that would enable them to more effectively compete with rival supercomputing powers, in particular China. Last month, Boris Shabanov of the Russian Academy of Sciences extended an Read more…

DOE Exascale Roadmap Highlights Big Data

Apr 7, 2014 |

If you’ve been following the US exascale roadmap, then chances are you’ve been following the work of William (“Bill”) J. Harrod, Division Director for the Advanced Scientific Computing Research (ASCR), Office of Science with the US Department of Energy (DOE). In January, Harrod asserted that the DOE’s mission to push the frontiers of science and Read more…

Instrument Science Preps for Exascale Era

Apr 3, 2014 |

The Big Data and Extreme-scale Computing (BDEC) workshop that took place in February in Fukuoka, Japan, brought together luminaries from industry, academia and government to discuss today’s big data challenges in the context of extreme-scale computing. Attendees to this invitation-only event include some of the world’s foremost experts on algorithms, computer system architecture, operating systems, Read more…
