Researchers are grappling with increasingly large quantities of image-based data. Machine learning and deep learning offer researchers new ways to analyze images quickly and more efficiently than ever before. Scientists at multiple national laboratories are working together to harness the potential of these tools.
After nearly five years of collaboration between researchers in academia, industry and national research laboratories -- including Berkeley Lab's Aydn BuluÁ--GraphBLAS, a collection of standardized building blocks for graph algorithms in the language of linear algebra, is publicly available.
Just one year after the Department of Energy's Exascale Computing Program began funding projects to prepare scientific applications for exascale supercomputers, the Pagoda Project -- led by Lawrence Berkeley National Laboratory -- has successfully reached a major milestone: making its open source software libraries publicly available as of Sept. 30, 2017.
Scientific Diplomacy: Three Berkeley Lab scientists are collaborating with two Techwomen -- Patu Ndango from Cameroon and Rim Abid from Tunisia -- on quality control methods for constrained environments.
The Argonne-led Multiscale Coupled Urban Systems project will create a computational framework for urban developers and planners to evaluate integrated models of city systems and processes. With this framework, city planners can better examine complex systems, understand the relationships between them and predict how changes will affect them. It can ultimately help officials identify the best solutions to benefit urban communities.
Scientists need to learn how to take advantage of exascale computing. This is the mission of the Argonne Training Program on Extreme-Scale Computing (ATPESC), which held its annual two-week training workshops over the summer.
Nuclear physicists at the Department of Energy's Oak Ridge National Laboratory and their partners are using America's most powerful supercomputers to characterize the behavior of objects, from subatomic neutrons to neutron stars, that differ dramatically in size yet are closely connected by physics. Through the DOE Office of Science's Scientific Discovery through Advanced Computing program, which concurrently advances science and supercomputing to accelerate discovery, ORNL is participating in two five-year computational nuclear physics projects.
A team of researchers in the US and Europe are part of the Real-Time Super Lab concept to study how electricity can be rerouted across vast distances to address disruptions. The team envisions that large-scale blackouts can be prevented by moving electricity intercontinentally, the same way utilities currently do regionally but at a much larger scale. Such global interaction can reduce the cost of outages and make electrical power grids of the future more resilient.
19-Sep-2017 A TOAST for next generation CMB experiments
Computational cosmologists at Berkeley Lab they recently achieved a critical milestone in preparation for upcoming CMB experiments: scaling their data simulation and reduction framework TOAST to run on all 658,784 Intel Knights Landing Xeon Phi processor cores on the NERSC's Cori. The team also implemented a new module to simulate the noise introduced when ground-based telescopes look at the CMB through the atmosphere.
An experiment called ALICE at the Large Hadron Collider is dedicated to the study of heavy-ion collisions. ALICE stands for 'A Large Ion Collider Experiment.' Its aim is spotting the high-energy, elementary particles, like electrons and gamma rays, streaming from the quark-gluon plasma, to explore the physics of the early universe. Oak Ridge National Laboratory physicist Thomas M. Cormier provides an update on the experiment.
Setting up a supercomputer is far more complicated than just bringing it home from the electronics store. Staff members of the Department of Energy's supercomputing user facilities spend years on the process, from laying out requirements through troubleshooting. In the end, they run some of the most powerful computers in the world to help solve some of science's biggest problems.
12-Jul-2017 Tackling disease in three dimensions: Supercomputers help decode RNA structure
In collaboration with staff from the Argonne Leadership Computing Facility, researchers at the National Cancer Institute have perfected a technique that accurately computes the 3-D structure of RNA sequences. This method, which relies on a computer program known as RS3D and supercomputer Mira gives researchers studying cancer and other diseases structural insights about associated RNAs that can be used to advance computer-assisted drug design and development.
In a milestone for studying a class of chemical reactions relevant to novel solar cells and memory storage devices, an international team of researchers working at the Department of Energy's SLAC National Accelerator Laboratory used an X-ray laser to watch 'molecular breathing' -- waves of subtle in-and-out motions of atoms -- in real time and unprecedented detail.
6-Jul-2017 ORNL researchers apply imaging, computational expertise to St. Jude research
In the quest to better understand and cure childhood diseases, scientists at St. Jude Children's Research Hospital accumulate enormous amounts of data from powerful video microscopes. To help St. Jude scientists mine that trove of data, researchers at Oak Ridge National Laboratory have created custom algorithms that can provide a deeper understanding of the images and quicken the pace of research.
5-Jul-2017 Will brain-inspired chips make a dent in science's big data problems?
Although neuromorphic computing is still in its infancy, Lawrence Berkeley National Laboratory (Berkeley Lab) researchers hope that these tiny, low-power, brain-inspired computing systems could one day help alleviate some of science's big data challenges. With funding from the Laboratory Directed Research and Development (LDRD) program, two groups of researchers are exploring how science might benefit from this new technology.
