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 arXiv.org. 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.
