Brookhaven Lab/ATLAS physicist Torre Wenaus describes an effort to trickle small 'grains' of data generated by the ATLAS experiment at the Large Hadron Collider (LHC) in Europe into small pockets of unused supercomputing time, sandwiched between big jobs on high-performance supercomputers.
5-Mar-2015 Between micro and macro, Berkeley Lab mathematicians model fluids at the mesoscale
The math whizzes at the Berkeley Lab's Center for Computational Sciences and Engineering are at the forefront of a neglected corner of the scientific world, building mathematical models for fluids at the mesoscale. The little-known field of fluctuating hydrodynamics could have enormous impacts in applications ranging from batteries to drug delivery to microfluidic devices.
20-Jan-2015 Pinpointing the magnetic moments of nuclear matter
Using supercomputing resources at the National Energy Research Scientific Computing Center at Berkeley Lab, a team of nuclear physicists has demonstrated for the first time the ability of quantum chromodynamics (QCD) -- a fundamental theory in particle physics -- to calculate the magnetic structure of some of the lightest nuclei. Their findings are part of an ongoing effort to further our understanding of the universe.
16-Dec-2014 A standard for neuroscience data
In November, Neurodata without Borders hosted a hackathon to consolidate ideas for designing and implementing a standard neuroscience file format. And BrainFormat, a neuroscience data standardization framework developed at Berkeley Lab, was one of several candidates selected for further investigation. It is now a strong contender to contribute to the development of a community-wide data format and storage standard for the neuroscience research community.
1-Dec-2014 Optimized algorithms boost combustion research
Turbulent combustion simulations, used in the design of more fuel-efficient combustion systems, have gotten their own efficiency boost, thanks to researchers from Berkeley Lab's Computational Research Division. They developed new algorithmic features that streamline turbulent flame simulations, which are commonly used in the design of combustion systems such as diesel engines; after testing the enhanced code on NERSC supercomputers, they were able to achieve dramatic improvements in simulation times, which will help reduce the time -- and thus the cost -- of designing new engines.
24-Nov-2014 Berkeley Lab algorithms help researchers understand dark energy
To unlock the mystery of dark energy and its influence on the universe, researchers must rely on indirect observations -- watching how fast Type Ia supernovae recede from us as the universe expands. The process of identifying and tracking these objects requires scientists to scrupulously monitor the night sky for slight changes, a task that would be tedious and time-consuming for the Dark Energy Survey without novel tools developed by Berkeley Lab and UC Berkeley researchers.
19-Nov-2014 Fast company
Researchers answering fundamental scientific questions in biology, climate and chemistry look to high performance computing and robust software. With its history of integrating experiment and computation, EMSL supports research into climate change, contaminated soil remediation, and energy production and storage with its Cascade supercomputer and enhanced NWChem computational chemistry software.
17-Nov-2014 Spiraling back in time
Using a code developed for GPU supercomputing architectures, including that of the Department of Energy's Oak Ridge National Laboratory's Cray XK7 Titan, to simulate the evolution of the Milky Way galaxy, a team of researchers from the Netherlands and Japan is a Gordon Bell Prize finalist.
22-Oct-2014 Brookhaven Lab launches Computational Science Initiative
NY-Building on its capabilities in computational science and data management, the US Department of Energy's Brookhaven National Laboratory is embarking upon a major new Computational Science Initiative. This program will leverage computational science expertise and investments across multiple programs at the Laboratory-including the flagship facilities that attract thousands of scientific users each year-further establishing Brookhaven as a leader in tackling the 'big data' challenges at the frontiers of scientific discovery.
17-Oct-2014 Atomic trigger shatters mystery of how glass deforms
A new study at the Department of Energy's Oak Ridge National Laboratory, published Sept. 24 in Nature Communications, has cracked one mystery of glass to shed light on the mechanism that triggers its deformation before shattering. The study improves understanding of glassy deformation and may accelerate broader application of metallic glass, a moldable, wear-resistant, magnetically exploitable material that is thrice as strong as the mightiest steel and ten times as springy.
17-Sep-2014 Predicting performance
Lignin, a low-cost byproduct of the pulp, paper and biofuels industries, can be transformed into a cheaper version of highly engineered graphite through a simple and industrially scalable manufacturing process.
28-Aug-2014 Materials scientists play atomic 'Jenga' and make a surprising discovery
Researchers got a surprise when they built a highly ordered lattice by layering thin films containing lanthanum, strontium, oxygen and iron. Although each layer had an intrinsically nonpolar (symmetric) distribution of electrical charges, the lattice had an asymmetric distribution of charges. The charge asymmetry creates an extra 'switch' that brings functionalities to materials when 'flipped' by external stimuli. The material defects induced polar behavior and can provide a new mechanism for manipulating electricity and magnetism in energy and information technologies.
20-Aug-2014 Junior researchers showing world the way to advanced nuclear fuel design
Two early-career Idaho National Laboratory researchers are earning international attention for their groundbreaking work. They're getting a long-sought look into the 3-D microstructure of irradiated nuclear fuel, then feeding that data into cutting-edge fuel behavior models. Their work will make the design and testing of even safer nuclear fuels more informed and efficient.
18-Aug-2014 Berkeley Lab's SPOT Suite transforms beamline science
For decades, synchrotron light sources have been operating on a manual grab-and-go data management model, but a recent deluge of data is quickly making this practice implausible. So Berkeley Lab X-ray scientists, facility users, computer and computational scientists, teamed up to create new tools for reducing, managing, analyzing and visualizing beamline data.The result of this collaboration is SPOT Suite, and it is already transforming the way scientists run their experiments at the ALS.
22-Jul-2014 Sandia ensures US nuclear weapons deterrent can remain effective, credible
As part of its mission of ensuring the nation's stockpile is safe, secure and effective as a deterrent, Sandia National Laboratories must make sure crucial parts can function if they're hit by radiation, especially a type called fast neutrons. It created a science-based program called QASPR, which combines computer modeling and simulation, and experiments and technology development.
17-Jul-2014 Hot plasma partial to bootstrap current
Supercomputers at NERSC are helping plasma physicists 'bootstrap' a potentially more affordable and sustainable fusion reaction. If successful, fusion reactors could provide almost limitless clean energy.
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
