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.

“Stream”-lining the Scientific Process at XSEDE

Jul 28, 2016 |

Indiana University and the National Science Foundation (NSF) have announced that Jetstream, the first-ever NSF-supported cloud resource for science and engineering research, will go into full operations as of September 1. But Jetstream is not your typical HPC supercomputer. “NSF, the IU Pervasive Technology Institute (PTI), and our many partners are embarking on a journey to operate a system that is both a production cloud and a first of a kind pilot project,” said IU’s Craig Stewart.

Alternative Supercomputing or How to Misuse a Computer

Jul 14, 2016 |

In 2008, the IBM Roadrunner supercomputer broke the petaflops barrier using the power of the heterogeneous Sony Cell Broadband Engine (BE) processor. A year prior, the Cell BE had already made its way into the consumer market as the engine inside the SonyPlaystation 3. The PS3’s accelerated design, Linux-capability and low price point…

Life in a Drop: Ohio Supercomputer Helps Prove Hydration’s Role in Protein Folding

Jul 14, 2016 |

It’s perhaps fitting that in the middle of the summer, when water management is a common challenge, that a paper in the Proceeding of the National Academy of Sciences (PNAS) offers more proof that life as we know it can’t occur without water. Using Ohio Supercomputing Center resources, researchers have shown the critical role water plays in actively guiding protein folding and movement. “For a long time, scientists have been trying to figure out how water interacts with proteins…

ISC Workshop Tackles the Co-development Challenge

Jul 12, 2016 |

The long percolating discussion over ‘co-development’ and how best it should be undertaken has gained new urgency in the race towards exascale computing. At a workshop held at ISC2016 last month – Form Follows Function: Do algorithms and applications challenge or drag behind the hardware evolution? – several distinguished panelists offered varying viewpoints. Yesterday, session organizer Tobias Weinzierl posted a summary synopsis of the workshop discussion on Weinzierl (Durham University) and co-organizer Michael Bader (Technische Universität München) are active participants in the ExaHyPE project (An Exascale Hyperbolic PDE (partial differential equation) Engine, funded by EU’s Horizon 2020 program).

Obama, NIH Announce Big Data Gathering Push for Precision Medicine

Jul 7, 2016 |

One could be forgiven for experiencing a bit of hopeful, skepticism in response to U.S. President Barack Obama Administration’s statement in May regarding re-energizing the “War Against Cancer.” The war against cancer is a many-decades old effort with mixed results – great progress in many areas but matched with disappointment in others. Winning the war Read more…

OLCF Researchers Scale R to Tackle Big Science Data Sets

Jul 6, 2016 |

Sometimes lost in the discussion around big data is the fact that big science has long generated huge data sets. “In fact, large-scale simulations that run on leadership-class supercomputers work at such high speeds and resolution that they generate unprecedented amounts of data. The size of these datasets—ranging from a few gigabytes to hundreds of Read more…

Genomic Sequencing at Children’s Mercy: Saving Time to Save Lives

Jul 1, 2016 |

Genomic sequencing – that is, rapid sequencing – is instrumental to diagnosing and treating critically ill patients, and managing the high data volumes involved in genomics is essential to the process. Children’s Mercy Hospital in Kansas City, MO, (354 beds, not-for-profit, treating children from birth through the age of 21) operates what it says is the world’s first whole genome sequencing center in a pediatric setting, where physicians, clinical laboratory scientists, molecular geneticists, bioinformaticians and software engineers work to sequence and analyze rare inherited diseases.

Baidu Researcher Pushes GPU Scalability for Deep Learning

Jun 20, 2016 |

Greg Diamos, senior researcher, Silicon Valley AI Lab, Baidu, is on the front lines of the reinvigorated frontier of machine learning. Before joining Baidu, Diamos was in the employ of NVIDIA, first as a research scientist and then an architect (for the GPU streaming multiprocessor and the CUDA software). Given this background, it’s natural that Diamos’ research is focused on advancing breakthroughs in GPU-based deep learning. Ahead of a paper he is presenting at the 33rd International Conference on Machine Learning, Diamos answered questions about his research and his vision for the future of machine learning.
