Vectors: How the Old Became New Again in Supercomputing

Sep 26, 2016 |

Vector instructions, once a powerful performance innovation of supercomputing in the 1970s and 1980s became an obsolete technology in the 1990s. But like the mythical phoenix bird, vector instructions have arisen from the ashes. Here is the history of a technology that went from new to old then back to new. But first, a few Read more…

NOAA Upgrades River Flow Forecasting on New Crays

Aug 16, 2016 |

The flooding now occurring in Louisiana and Mississippi is a stark reminder of how disruptive and potentially dangerous floods can be. Today the National Oceanic and Atmospheric Administration (NOAA) launched a new simulation tool – the National Water Model (NMW) – running on NOAA’s new Cray XC40 supercomputers that greatly extends and enhances NOAA’s ability Read more…

Cray Revises FY16 Forecast, Citing Chip Delays, Market Slowdown, Smoke

Aug 4, 2016 |

Cray’s annual revenue projections took a hit on Tuesday as processor delays, market uncertainties, and a recent “smoke event” lead the supercomputing company to reduce its FY16 guidance by $175 million. Cray now expects total yearly revenue to be in the $650 million range, down from its previous estimate of $825 million. In 2015, the company Read more…

Titan Simulation Reveals New Details of Fissioning Plutonium

Jul 26, 2016 |

In a first study of its kind, a team led by the University of Washington’s Aurel Bulgac captured the real-time dynamics of a fissioning plutonium-240 nucleus by simulating the process on the Titan supercomputer at the Oak Ridge Leadership Computing Facility (OLCF), a US Department of Energy (DOE) Office of Science User Facility. To create Read more…

Cray Bakes Big Data Software Framework Into Urika-GX Analytics Platform

May 24, 2016 |

Cray continued its courtship of the advanced scale enterprise market with today’s launch of the Urika-GX, a system that integrates Cray supercomputing technologies with an agile big data platform designed to run multiple analytics workloads concurrently. While Cray has pre-installed analytics software in previous systems, the new system takes pre-configuration to a new level with an open software framework designed to eliminate installation, integration and update headaches that stymie big data implementations.

Europe’s Fastest Supercomputer to Get Pascal GPU Upgrade

Apr 6, 2016 |

Already Europe’s fastest supercomputer at 7.8 petaflops, the Piz Daint (hybrid CPU/GPU Cray XC30) at the Swiss National Computing Center (CSCS) will double its performance with a massive upgrade that involves switching to NVIDIA’s newest Pascal GPU architecture and merging with Piz Dora (Cray XC40), a smaller CPU-based machine. The announcement was made at GTC16…

Titan Helps Shed Light on Membrane Lipids’ Multiple Roles

Apr 4, 2016 |

Lipid molecules are schizophrenic. One end likes to hang out with a charged crowd (think water); the other prefers neutral neighbors (think fats). Most of us remember those funky illustrations of the bilayer lipid membrane structure that encloses animal cells from high school biology. Recently, Titan supercomputer was used to show cell membranes may be Read more…

Titan Sheds Light on Universe’s Second Flicker

Mar 9, 2016 |

Right after the Big Bang the universe was filled with hot, ionized hydrogen (H) and helium (He) gas, a bright torch if you will. By 400,000 years later the flame had dimmed as the gas de-ionized (atoms recaptured electrons) and radiation shifted to ‘invisible’ wavelengths. So started the Cosmic Dark Ages. Now a group of Read more…

Getting ready for KNL? Take a Lesson from NERSC on Optimizing

Feb 10, 2016 |

NERSC is beginning to tell the world how to optimize applications to run on the new Intel Xeon Phi processors, code name Knights Landing (KNL), that will boot in self-hosted mode to power over 9,300 nodes of the Cori supercomputer by the summer of 2016. Indeed, general availability of KNL is expected before the end Read more…
