Battery Boost (March 23, 2015)
CSMD: John Turner
ORNL computing software aims to help electric vehicle industry better design high-performing and safe lithium-ion batteries through simulation
Rechargeable lithium-ion batteries are commonly found in portable electronics such as cell phones and notebook PCs. They're also gaining popularity in electric vehicles, where their compact, lightweight build and high-energy storage potential offers a more efficient and environmentally safe alternative to nickel metal hydride and lead-acid batteries traditionally used in vehicles.
Scientists at the Department of Energy's Oak Ridge National Laboratory have developed modeling software to help other researchers and battery manufacturers improve the design of lithium-ion batteries for electric vehicles. The modeling tool, known as the Virtual Integrated Battery Environment, or VIBE, will allow researchers to test lithium-ion batteries under different simulated scenarios before the batteries are built and used in electric vehicles.
Researchers Get Warmer in Understanding High-Temperature Superconductors (March 10, 2015)
CSMD: Paul Kent

Using theCray XK7 Titan supercomputer at the Oak Ridge Leadership Computing Facility (OLCF), a DOE Office of Science User Facility, the team made its own leap in materials science research.
The group, led by ORNL researcher Paul Kent, advanced its understanding of superconducting by performing the first ab initio simulation of a high-temperature superconducting material, or cuprate. Read the full article [here].
Upgrading Modeling and Simulation with the Eclipse Integrated Computational Environment (Jan 2015)
Jay Jay Billings, Alexander J. McCaskey, Andrew Bennett, Jordan H. Deyton, Hari Krishnan, Taylor Patterson, Anna Wojtowicz
Researchers have taken the tools in Eclipse that are used for authoring scientific software and repurposed them for using scientific software.
The result is the Eclipse Integrated Computational Environment (ICE); a general purpose, easily extended M&S platform that significantly updates the way computational scientists interact with their software. It improves productivity and streamlines the workflow for computational scientists when they need to create input files, launch jobs on local or remote machines, and process output. Since it is based on the Eclipse Rich Client Platform, developers can update it to support new codes or add new tools just as easily as users can perform simulations of nuclear fuels or visualize neutron scattering data.

CSMD's Nageswara Rao Wins R&D 100 Award (July 2014)
Diagnosis Using the Chaos of Computing Systems, or DUCCS, was developed at ORNL by Nageswara Rao.
DUCCS ultra-lightweight software quickly and nonintrusively detects a variety of hardware faults in processing units, accelerators, memory elements and interconnects of large-scale high-performance computing systems such as supercomputers, clusters and server farms. The software combines chaotic map theory with advanced CPUs and CPU systems to detect component faults in systems that handle large computational problems such as scientific computations, weather predictions and web data processing. DUCCS software provides critical diagnosis information that contributes to the resilience of computing systems in terms of error-free computations and sustained capacity.
The research was funded by the DOE's Mathematics of Complex, Distributed, Interconnected Systems Project, Applied Mathematics Program, Office of Advanced Scientific Computing Research.
ORNL Joined the Eclipse Foundation (June 2014)
Jay Jay Billings
ORNL joined the Eclipse Foundation, which manages both an open source community and the development of the popular Eclipse Integrated Development Environment. The effort to join the Foundation was led by Jay Jay Billings of the Computer Science Research group to address several pressing issues for the NEAMS Integrated Computational Environment (NiCE).
Membership in the Foundation includes many benefits and applies site-wide to all UT-Battelle employees and subcontractors (including ORAU/ORISE post-graduates). In addition to providing access to a user base of more than nine million users for Eclipse projects, the Eclipse Foundation also provides marketing and advertising support, intellectual property-friendly contributor agreements to help with contributions to projects from third-party developers and access to hundreds of skilled developers from some of the biggest (and smallest!) companies in the tech sector. The process of proposing new projects is also streamlined for members since the necessary agreements are already in place.
Membership also allows ORNL to participate in the new Eclipse Science Working Group (SWG). The SWG is focused on creating new, science-focused Eclipse projects with completely new code bases or contributions from Foundation members in a technology-agnostic setting (read "not only Java projects"). The SWG also acts as a support community related to scientific activities projects with Eclipse.
Jay pursued membership in the Foundation primarily because of growing contributions from external collaborators to NiCE. Each contributing organization has its own set of policies related to open source software, intellectual property rights and code contributions, so the easiest and safest route was to creating a new project with a third party software Foundation. Since NiCE is based on the Eclipse Rich Client Platform and the NiCE team has been involved with the community for a number of years, the Eclipse Foundation was the obvious choice. A proposal to create the Eclipse Integrated Computational Environment, with NiCE as the initial contribution, is currently under review.

Kate Evans' Work Recognized by Alma Mater (May 2014)
The work of CSMD researcher and Group Leader Kate Evans is currently being highlighted in an article in Haverford College's quarterly online magazine. The article "Investigating a Changing Climate" outlines work being carried out by Haverford graduates. In particular, the article touches on the work Kate has done with the Community Climate System Model which has been modeling global climate with increasing complexity and fidelity since 1983. Running on ORNL's Titan supercomputer, this model is able to calculate temperature, wind, rain, humidity, and other variables on a virtual grid covering the globe. These models can reproduce the past and predict how the climate will change in the coming decades and centuries.

Patent Issued for "Coordinated Garbage Collection for RAID Array of Solid State Disks" (May 2014)
A team of researchers at ORNL invent a novel architecture for high performance non-volatile storage systems.
Non-volatile solid-state storage technologies such as Flash storage are increasingly used to accelerate I/O intensive workloads across a broad spectrum of domains from scientific computing to cloud computing and traditional enterprise IT. These storage technologies hold the promise of significantly improving the performance of a variety of workloads be they hadoop workloads, massive scale simulation outputs, to enterprise database workloads. While these technologies hold significant promise to accelerate these workloads, many solid-state storage technologies can suffer from significant performance degradation due to internal management tasks within the solid-state device. These internal management tasks, most notably garbage collection tasks used to reclaim free storage space after, can reduce performance by as much as 70 percent. While these internal management tasks occur infrequently on any one device, as organizations deploy multiple solid-state storage devices in common storage configurations such as RAID, the probability of performance degradation increases dramatically. To alleviate this, the ORNL team developed a novel architecture to coordinate these internal storage management tasks across a large pool of storage devices. This architecture significantly reduces the probability of productive I/O operations becoming degraded by these internal management tasks. For further information please refer to the full patent (patent number 8,713,268 B2) and the paper: David A. Dillow, Galen M. Shipman, Feiyi Wang, Sarp Oral, Junghee Lee, Youngjae Kim, "Coordinating Garbage Collectionfor Arrays of Solid-State Drives," IEEE Transactions on Computers, vol. 63, no. 4, pp. 888-901, April 2014, doi:10.1109/TC.2012.256

Postdoctoral Researcher Tianyu Jiang Awarded in "Best Dissertation" Competition
Tianyu Jiang, a postdoctoral researcher at Oak Ridge National Laboratory's Climate Change Science Institute, achieved 3rd place in the Chinese-American Oceanic and Atmospheric Association's "best dissertation" competition. Jiang, a member of CCSI's Earth System Modeling Group, received the award February 5 in Atlanta during the 94th annual meeting of the American Meteorological Society.
Jiang said what gave him the upper hand in the competition was a summer spent as a part of ORNL's Higher Education Research Experiences program, under the supervision of Kate Evans, leader of the ORNL Computational Earth Sciences Group and a member of CCSI. "My experience here was world class," said Jiang. "I had the chance to use high-performance computers and collaborate with the entire team to do cutting-edge work."
Jiang's thesis, "Understanding the Scale Interaction of Atmospheric Transient Disturbances and Its Coupling with the Hydrological Cycle over the Pacific-North American Regions," focused on the connection between climate over the North Pacific and extreme weather - freezing temperatures, high-impact precipitation, droughts, and other severe events. "Understanding extreme weather under a changing climate is becoming more and more challenging and urgent, not only because of the public's immediate need for weather information, but also the increasing concern from policymakers," said Jiang.

CLIMATE - Going small with big computers . . .
ORNL's supercomputers are allowing climate scientists to zoom in on smaller and smaller areas to try to determine whether local and regional droughts influence climate extremes on a larger scale. What is the probability of a drought developing in the Southwest this decade? Ultra-high-resolution climate models may improve our ability to provide informed projections. In the highest-resolution model, grid cells are a mere one-quarter of a degree (23 miles) wide. "Data at this scale is only accessible with leadership computing resources," says ORNL mathematician Rick Archibald, one of nine ORNL researchers collaborating with scientists at Lawrence Berkeley, Lawrence Livermore and Los Alamos national laboratories on the Ultra-high-resolution Global Climate Simulation project.

Thomas R. O'Donnell - DEIXIX Magazine
With the help of Oak Ridge computations, scientists are probing the properties of macroscale sponges made of nanoscale carbon-boron tubes. The material could soak up oil spills, help store energy or meet other needs.
In 2007, when Oak Ridge National Laboratory (ORNL) researchers calculated that adding boron would bend carbon nanotubes, they did little with the information.
Boron was one of several elements the computational scientists plugged into their model as they investigated ways to induce useful changes in nanotube structures. There were experiments to compare with the results of most of their calculations. There weren't any to check against the boron-doped nanotube simulations.
"We didn't think anything about boron, really," says Bobby Sumpter, Chemical and Materials Sciences Group leader and director of ORNL's Nanomaterials Theory Institute. "We thought it was interesting how it preferred negative curvature, and we kind of just left it at that."
Then Humberto Terrones, an ORNL-affiliated researcher from Belgium's Université Catholique de Louvain, came to visit last year. He and his brother, Mauricio, of Pennsylvania State University and Japan's Shinshu University, were investigating new nanotube materials.
Humberto Terrones "was talking about how they'd observed these three-dimensional-looking structures when they doped boron in," Sumpter recalls. "I said, 'But, Humberto, remember our results? Where we found these interesting effects and we think we understand exactly what happens?' I hadn't realized they'd done experiments for boron and just learned about it over a casual discussion - which actually turn out to be usually the most productive scientific discussions - just a cup of coffee with a white board."
Sumpter and Vincent Meunier of Rensselaer Polytechnic Institute recalculated the boron results and published them jointly with Rice University doctoral student Daniel Hashim's discovery of three-dimensional, macro-scale nanosponges. "It's always good to have experimental evidence that backs up theory or vice versa," Hashim says. "In this case we made the theory and the experimental evidence together and it gave this paper a lot more impact."
