NERSC is Busily Using Dungeons to Slay Code Dragons

Aug 24, 2016 |

Work to modernize codes for use on the National Energy Research Scientific Computing Center (NERSC) Cori supercomputer and its Intel Xeon Phi Knight’s Landing manycore architecture is making steady progress, says NERSC, which has now held eight Dungeon code development sessions with Intel and Cray. The most recent was held earlier this month. These Dungeon Read more…

Gazing into Computational Biology’s Crystal Ball

Aug 23, 2016 |

Sorting out computational biology’s future is tricky. It likely won’t be singular. First-principle, mechanistic simulation has so far proven challenging but could eventually become game changing. Meanwhile pattern recognition and matching in massive ‘omics’ datasets have been extremely productive and likely to remain dominant at present. Now, an MIT professor and colleagues write that two Read more…

ARM Unveils Scalable Vector Extension for HPC at Hot Chips

Aug 22, 2016 |

ARM and Fujitsu today announced a scalable vector extension (SVE) to the ARMv8-A architecture intended to enhance ARM capabilities in HPC workloads. Fujitsu is the lead silicon partner in the effort (so far) and will use ARM with SVE technology in its post K computer, Japan’s next flagship supercomputer planned for the 2020 timeframe. This is an important incremental step for ARM, which seeks to push more aggressively into mainstream and HPC server markets.

Container Testing Reveals ‘Memory Pressure’ on Apps

Aug 18, 2016 |

With early adopters of application container technology completing early testing in multi-tenant settings, potential performance issues are beginning to surface. Among them, according to hyper-scaler LinkedIn, is a Linux kernel feature called “control groups” used with most containers to assign resources. In an analysis based on several months of “pressure testing,” Zhenyun Zhuang, a software Read more…

FM Global Researchers Say ‘ADIOS’ to Bottlenecks

Aug 16, 2016 |

Aug. 16 — Researchers from commercial and industrial property insurer FM Global want to improve fire protection standards across the country. The company, which insures one in three Fortune 1000 companies with a unique focus on helping clients prevent losses, is dedicated to understanding how fires spread and, conversely, how they can be contained.

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…

DOE Invests $16M in Supercomputer-based Materials Design

Aug 16, 2016 |

Materials science got a boost today when the Department of Energy announced it would invest $16 million over the next four years to accelerate the design of new materials “through use of supercomputers.” The program will focus on software development with an eye towards being able to eventually run on exascale machines. Two four-year projects Read more…

China to Launch ‘Quantum’ Satellite; Is U.S. Falling Behind?

Aug 15, 2016 |

Within the next few days China will launch a ‘quantum’ communications satellite heralding yet another major technology achievement for the world’s largest and most populous country, according to a report today in The Wall Street Journal. It’s part of China’s drive to build a hack-proof communications. This is impressive show of science and technology strength Read more…

Think Fast – Is Neuromorphic Computing Set to Leap Forward?

Aug 15, 2016 |

Steadily advancing neuromorphic computing technology has created high expectations for this fundamentally different approach to computing. Its strengths – like the human brain it attempts to mimic – are pattern recognition (space and time) and inference reasoning. Advocates say it will also be possible to compute at much lower power than current paradigms. At ISC Read more…

Intel to Acquire AI Startup Nervana Systems

Aug 9, 2016 |

If we needed another sign that Intel is serious about mining AI market opportunities, it came today when the chip company announced it had inked a “definitive agreement” to acquire artificial intelligence and deep learning company Nervana Systems. Financial terms haven’t been disclosed yet, but a source familiar with the deal told Recode it’s worth more Read more…

K Computer Runs First Accurate Model of Abrupt Torrential Rain

Aug 9, 2016 |

Supercomputers have long been used in weather forecasting but not for abrupt, highly localized events. Now for the first time, a group of researchers using the K computer used the powerful K computer and advanced radar observational data to accurately predict the occurrence of torrential rains in localized areas. These latter events can arise in Read more…

Sub-Sahara Tree Survey Finds Success with AWS, Hybrid Cloud

Aug 4, 2016 |

Vegetation is such an important part of climate health that scientists are working to perfect biomass measurement techniques. A region of particular interest is a coast-to-coast band of sub-Sahara Africa that is home to an estimated one billion trees and shrubs. Scientists from the University of Minnesota and the NASA Center for Climate Simulation (NCCS) were able to arrive at this figure using a combination of NASA resources and commercial cloud technologies to process satellite image data.

MPI Is Not Perfect … Yet

Aug 3, 2016 |

The Message Passing Interface (MPI) is the standard definition of a communication API that has underpinned traditional HPC for decades. The message passing programming represents distributed-memory hardware architectures using processes that send messages to each other. When first standardised in 1993-4, MPI was a major step forward from the many proprietary, system-dependent, and semantically different message-passing libraries that came before it.
