The effort has brought significant new funding to National Isotope Development Center (NIDC) at Oak Ridge National Laboratory.

A new, custom-built, database-driven website, isotopes.gov, has been designed and developed for the National Isotope Development Center (NIDC). The NIDC is the sole federal government source of stable- and radio-isotope products for science, medicine, security and applications with an annual revenue approaching $40M per year. Since going live in May 2011, isotopes.gov has provided customers detailed information concerning NIDC activities, funding opportunities, jobs and training, meetings and workshops, outreach and education, production research, and the Isotope Business Office (IBO), which is located here at ORNL. The website also hosts the new Online Catalog of Isotope Products, which allows customers to interactively explore the catalog and submit requests for quotations and new products. Developed by Eric Lingerfelt (CSMD) and Michael Smith (Physics), the website has successfully brought the NIDC's web presence for the forefront and encouraged interaction with new and existing customers. It has also served to educate the public on the important role that isotopes play in society.

Special Category

Rick Archibald was awarded the Special Category award for his work in the utilization of support vector machines (SVMs) to semiautomatically perform endmember extraction from hyperspectral data. The strengths of SVM are exploited to provide a fast and accurate calculated representation of high-dimensional data sets that may consist of multiple distributions. Once this representation is computed, the number of distributions can be determined without prior knowledge. For each distribution, an optimal transform can be determined that preserves informational content while reducing the data dimensionality and, hence, the computational cost. Finally, endmember extraction for the whole data set is accomplished. Results indicate that this SVM-based endmember extraction algorithm has the capability of semiautonomously determining endmembers from multiple clusters with computational speed and accuracy while maintaining a robust tolerance to noise.

Individual Achievements

Intern Roisin Langan wins best abstract award at student poster session

Roisin Langan, an intern at Oak Ridge National Laboratory (ORNL), spent last summer improving the ability of climate models to predict the variability and extremes of precipitation. With guidance from her mentors, Richard Archibald and Kate Evans of ORNL's Climate Change Science Institute, Langan analyzed data generated on the Oak Ridge Leadership Computing Facility's Titan supercomputer. Her project, titled "Stochastic Representation of Unresolved Processes in Climate Models," garnered attention labwide, winning the best abstract award at ORNL's Research Alliance in Math and Science (RAMS) banquet, a student poster session held August 8. Research in this field could result in more accurate warning systems for extreme events, such as flooding, droughts, and heat waves, and help stakeholders plan economic and humanitarian relief efforts. "This experience helped me gain invaluable networking channels, experience, and instruction in effective scientific communication," said Langan, a recent graduate of the University of California, Santa Barbara. Now an intern through ORNL's Nuclear Engineering Science Laboratory Synthesis program, she hopes to enter a graduate program in computational science in fall 2014. - Jennifer Brouner

Jack Dongarra to Receive Ken Kennedy Award for Software Technologies that Power Supercomputers to Tackle Big Scientific Problems

DENVER, CO, October 8, 2013 - Jack Dongarra of the University of Tennessee will receive the ACM-IEEE Computer Society Ken Kennedy Award for his leadership in designing and promoting standards for mathematical software used to solve numerical problems common to high performance computing (HPC). His work has led to the development of major software libraries of algorithms and methods that boost performance and portability in HPC environments, which rely on supercomputers and parallel processing techniques for solving complex computational problems. Dongarra, the Distinguished University Professor at the University of Tennessee, is the founder and director of the Innovative Computing Laboratory at the University, and holds positions at Oak Ridge National Laboratory and the University of Manchester. He will receive the Kennedy Award on November 19 in Denver at SC13, the International Conference on High Performance Computing.

ACM President Vint Cerf cited Dongarra's role in anticipating the staggering challenges facing the HPC world. "Jack saw the need to keep pace with the evolution in HPC hardware and software in a world that demands higher speeds and performance levels. His innovations have contributed imensely to the steep growth of high performance computing and its ability to illuminate a wide range of scientific questions facing our society."

IEEE Computer Society President David Alan Grier said Dongarra's work remains authoritative. "I'm so pleased to see this award go to Jack Dongarra because he did such foundational work in scientific computing. That work was important in my early career and it remains an influential body of work."
Dongarra is a leader in research on implementing linear algebra algorithms for high performance computing architecture that has defined the mathematical software field. Many supercomputer vendors have adopted these software packages as the basis of their own numerical libraries. The software involves the use of memory hierarchies, performance tuning parameters, and other techniques to achieve performance and portability.

He has also been a major force in developing standards for mathematical software that are widely accepted in computer and computational science for evaluating the performance of supercomputers. They include LINPACK and LAPACK, software packages used since the 1970s for solving systems of linear equations. In 1993, he formed the Top500 table which used his LINPACK benchmark to show the 500 most powerful commercially available computer systems. These benchmarks enable users to exploit their existing computer hardware to solve much larger problems at lower additional cost.

The Kennedy Award cited Dongarra for "influential contributions to mathematical software, performance measurement, and parallel programming, and significant leadership and service within the HPC community."

A Fellow of ACM, IEEE, AAAS, and SIAM, Dongarra is the recipient of the first IEEE Medal of Excellence in Scalable Computing, and the first recipient of the SIAM Special Interest Group on Supercomputing's award for Career Achievement. He was awarded the IEEE Computer Society Sidney Fernbach Award and received the IEEE IPDPS 2011 Charles Babbage Award. He is a member of the National Academy of Engineering.

Dongarra is a Distinguished Research Staff member at Oak Ridge National Laboratory and an adjunct professor of Computer Science at Rice University, and holds the Turing Fellowship at the University of Manchester. He is also director of Tennessee's Center for Information Technology Research. Before joining the University of Tennessee, he was a senior scientist at Argonne National Laboratory. He received a B.S. degree in Mathematics from Chicago State University, an M.S. degree in Computer Science from the Illinois Institute of Technology, and a Ph.D. in Applied Mathematics from the University of New Mexico. 

ACM and the Computer Society co-sponsor the Kennedy Award, which was established in 2009 to recognize substantial contributions to programmability and productivity in computing and significant community service or mentoring contributions. It was named for the late Ken Kennedy, founder of Rice University's computer science program and a world expert on high-performance computing. The Kennedy Award carries a US $5,000 honorarium endowed by the ACM Special Interest Group on Computer Architecture (SIGARCH) and the Computer Society.

Webster Appointed Science Fellow
September 2013

Clayton Webster was selected as a Kavli Frontiers of Science Fellow in July, 2013, and asked to participate in the German-American Kavli Frontiers of Science symposium, which is jointly organized by the Alexander von Humboldt Foundation and the US National Academy of Sciences (NAS). The symposium brings together the very best young scientists to discuss exciting advances and opportunities in a broad range of disciplines. A committee of NAS members selects the participants from among young researchers who have already made recognized contributions to science, including highly cited papers and recipients of major fellowships and awards. These are highly interdisciplinary symposia emphasizing communication of a wide range of contemporary science topics across the traditional disciplines.

The symposia, which are both national and international in scope, enable emerging and outstanding young scientific leaders to become acquainted with their counterparts in a broad range of disciplines, and to stimulate long-term relationships with their peers. The participants become acquainted with their colleagues in other nations, and in this way build an international network of scientific communication and cooperation. The symposia also serve to inform these young scientists about the challenges and opportunities being addressed at the frontiers of other scientific disciplines, and to broaden their perspectives on the scientific enterprise as a whole.

Researchers Win Gauss Award
July 2013

Three ORNL researchers were a part of the team that received international recognition. The team was given the Gauss Award at the International Supercomputing Conference (ISC) for the most outstanding paper in the field of scalable supercomputing.

The paper, "TUE, a New Energy-Efficiency Metric Applied at ORNL's Jaguar," outlines how to get a more accurate representation of the data-center energy efficiency. Two new metrics are proposed; they are ITUE (IT-power Usage Effectiveness) and TUE (Total-power Usage Effectiveness). Currently, Power Usage Effectiveness (PUE) is used to measure the efficiency. ITUE is similar to PUE but "inside" the IT. TUE combines the two for a total efficiency picture. It provides a ratio of total energy, separating internal and external support energy uses from the specific energy used in the HPC. The paper concludes with a field application of the method at ORNL's Jaguar supercomputer.

The research was a collaboration between government, national labs and industry aimed at being better able to ensure the most accurate and wise use of power going forward for computer systems and computing facilities.The team includes Chung-Hsing Hsu, Stephen W. Poole and Don E. Maxwell, ORNL; Michael K. Patterson, Intel; William Tschudi and Henry Coles, LBNL; David J. Martinez, SNL; and Natalie Bates, Energy Efficient HPC Working Group (EEHPC WG).

At ORNL, power-aware computing has been an active area of research, also a focal point, within the DoD funded program within Computer Science and Mathematics Division. We have done a fairly large body of this work, and Dr. Chung-Hsing worked in this area when he was at Los Alamos National Laboratory.

Going forward, the team plan to measure energy efficiency at other facilities to further develop TUE. The ISC organizers have requested that the researchers return for ISC 2014 to follow up on the work after TUE is measured at more supercomputing facilities. ORNL will continue down this research path and develop it as much as possible. We are currently working with the EEHPC WG to create guidelines for procurement documents that include energy considerations.

"Over time, TUE and ITUE can create the same pull and success that PUE has and further improve the energy efficiency of supercomputers and computing facilities," says Dr. Hsu.

The Gauss Award is sponsored by the German Gauss Center for Supercomputing, a collaboration of the German national supercomputing centers at Garching, Jülich and Stuttgart, and is presented annually at ISC. ISC is the oldest global conference and exhibition for high performance computing and drew 2,500 attendees this year. A committee chooses the most outstanding paper in the field of scalable supercomputing from all of the papers submitted for Research Paper Sessions. The winner of the award receives a 3,000 Euro prize and presents their paper at the conference.

CSMD researcher Bobby Sumpter, along with fellow ORNL researchers Witold Nazarewicz and Stan Wullschleger, has been selected as a 2013 UT-Battelle Corporate Fellow.
July 2013

"Witek, Bobby and Stan are honored both for their individual achievements and for their contributions as mentors and collaborators," Lab Director Thom Mason said. "Their superlative leadership in nuclear physics, computational chemistry and materials, and climate and environmental sciences, respectively, has advanced the frontiers of knowledge across fields of critical importance to ORNL's mission."

"Witek" Nazarewicz is an international leader in theoretical nuclear physics and is widely recognized as a principal driving force behind research on the physics of exotic nuclei. Witek served as scientific director of the Holifield Radioactive Ion Beam Facility from 1999 to 2011. He holds professorships at the University of Tennessee, Knoxville, where he is the James McConnell Distinguished Professor of Physics.

Bobby Sumpter leads both the Computational Chemistry & Materials Science group in the Computer Science &Mathematics Division and the Nanomaterials Theory Institute at the Center for Nanophase Materials Sciences. He has been exceptionally productive at the confluence of theory and experiment, working across organizational boundaries to provide theory and modeling leadership across disciplines.

Pratul Agarwal (Patent)
May 2013

Pratul Agarwal was awarded U.S. Patent No. 8,417,461 for "Identification and Modification of Dynamical Regions in Proteins for Alteration of Enzyme Catalytic Effect"

According to the patent's abstract, the patent covers "A method for analysis, control, and manipulation for improvement of the chemical reaction rate of a protein-mediated reaction is provided. Enzymes, which typically comprise protein molecules, are very efficient catalysts that enhance chemical reaction rates by many orders of magnitude. Enzymes are widely used for a number of functions in chemical, biochemical, pharmaceutical, and other purposes. The method identifies key protein vibration modes that control the chemical reaction rate of the protein-mediated reaction, providing identification of the factors that enable the enzymes to achieve the high rate of reaction enhancement. By controlling these factors, the function of enzymes may be modulated, i.e., the activity can either be increased for faster enzyme reaction or it can be decreased when a slower enzyme is desired. This method provides an inexpensive and efficient solution by utilizing computer simulations, in combination with available experimental data, to build suitable models and investigate the enzyme activity."

Distinguished Employee Program

January

Norbert Podhorszki worked with Mathieu Gontier from NUMECA International S.A to implement an efficient I/O module for the FineTM/Turbo solver for CFD applications. The new solver has been used by RAMGEN Power Systems, LLC on Jaguar, with a tenfold increase in checkpoint/restart performance, allowing this application to scale much better. The unusual characteristics of the solver is that, for load balancing reasons, each processor holds multiple and a variable number of pieces of each variable because of a non uniform balancing of the structured model over the processes. This renders all traditional I/O solutions very inefficient, especially their original host-slaves IO approach based on CGNS on a very large number of sub domains, and which becomes the bottleneck at scale. The buffering mechanism and the aggregation I/O method provided by ADIOS, combined with an easy-to-use API, helped them to separate the problem of I/O performance from the definition of I/O in the application itself and to provide efficient I/O performance on Jaguar. Additionally, the self-describing data format of ADIOS allows the application to restart from a previous checkpoint on an arbitrary number of processes. In numbers, a computation originally requiring about 2000-sec was optimized until 120-sec with a non negligible memory over consumption, against 40-sec with ADIOS without additional memory.

February

Cory Hauck is the Oak Ridge node leader for Ki-Net, a new research network funded by the NSF for the next five years. Research networks are a new mode of operation under the Division of Mathematical Sciences at the NSF. Their purpose is to facilitate travel and interaction between institutional members.  Ki-Net is focused on kinetic theory, primarily on "emerging applications" in quantum dynamics, network dynamics, and biological sciences.  It is one of only three funded projects and the only one in applied mathematics.

March

Cindy Sonewald is an exemplary employee that is always willing to help others and strives to deliver the utmost quality and timeliness as a group's administrative assistant. She has built a relationship with all of the groups and no one has a problem with coming to her for help. Cindy has worked above and beyond the call of duty on everything from planning meetings to handling even the most in-depth details of subcontracts so that the researchers can be left to their science. She regularly works overtime to help with proposals, budgets and purchases. And if the programming ever gets the researchers down, they can always go to Cindy for a good laugh or a brief discussion on literary classics for a short break. Cindy's contribution to the group is phenomenal and we wouldn't be the same without here.

May

Forrest Hoffman - When the Climate SciDAC call was announced it became obvious that instead of the large monolithic proposals that had been funded in previous calls, DOE was looking for smaller more focused proposals. This opened the door for competition from new players interested in winning support but also threatened to undermine the longstanding cooperation between ORNL and some of the other principal Labs in Climate. Thus, the landscape for negotiating the collaboration between many of the partners became much more complex and uncertain. Forrest was asked to serve as the ORNL point of contact for the definition phase which involved several meetings to negotiate the content of several SciDAC themes mostly in content areas where Forrest had no personal interest and no prospect of support for himself. When the negotiations were complete Forrest had managed to help define three subject areas in biogeochemistry, multiscale processes and ice sheets. Forrest and others at ORNL were then able to bid for and win support for work in all three defined SciDAC Climate areas. Furthermore, Forrest was able maintain the positive and collaborative atmosphere between ORNL and the other labs principally involved in climate science. This epitomizes the selfless leadership we sometimes ask of our staff; Forrest had to look to the bigger picture and not just focus narrowly on his own research interests and needs.

June

Qing Gary Liu has been performing research in High-performance I/O and has been developing the ADaptable I/O System (ADIOS) software. ADIOS is going to reach its 5th release since 2008 and Gary has continuously improved it. His aggregation strategy to write data out has proved to be the fastest technique at scale at OLCF, therefore all applications that turned to use ADIOS due to their I/O problems, ended up exclusively using his method for running on 100k cores and up. S3D, a combustion simulation code from Sandia has been using ADIOS since before the first release, and has been a driving application for ADIOS. Gary has been the main contact for I/O related work with the authors at Sandia and has been improving their I/O. Gary is an extremely dedicated asset to the Scientific Data Group, who makes sure that ADIOS is high-quality software and is always ready to help applications pushing the limits of I/O on our petascale systems.

In the last month Gary worked nonstop to lead the ADIOS effort to get our next major release, which included I/O staging and new and enhanced reading. He has also worked to assist the S3D team, lead by Jackie Chen, to have high performance I/O.

July

Eirik Endeve is the CSMD distinguished employee for July. He just published his second major paper in The Astrophysical Journal. Both papers were superb and comprehensive studies of the stationary accretion shock instability in core collapse supernovae and the turbulence it induces, the latter of which has important ramifications for the supernova explosion mechanism and for all future three-dimensional supernova models.

August

Jennifer Williams and Lora Wolfe were instrumental in organizing the Discovery 2020 Workshop in Santa Fe, New Mexico that focused on quantum computing, modeling and simulation, and programming languages, which will provide analytics and advanced computing in the 2015/2020 time frame. The workshop was hosted by ORNL, Los Alamos National Laboratory, and the Department of Defense. Jennifer and Lora organized the location; meeting logistics; materials needed for the workshop; interacted with the sponsor on attendee requirements; work with the speakers on presentation materials, travel, and honorariums; and all social activities for the workshop. In advance of the workshop, they set up participants FOBs so they could log onto the ORNL system where OpenSHMEM was loaded and made sure that NCCS had everything set up on the computer. In Santa Fe, they made sure all of the participants were taken care of throughout the workshop and that all special dietary needs were handled. They also made sure that all of the networking, AV, seating, and WebEx was taken care of onsite during the entire workshop. They shipped manuals back to participants’ sites so they did not have to carry them in their luggage, and made all of the CD's of the workshop. Once they returned from travel, Jennifer completed all of the close-out of the workshop, which entails consolidating the surveys from the participants and providing feedback to the sponsor and the hosting of WebEx for remote participants. The work they did was so excellent, that the DoD organizers have already given high praise to Jennifer and Lora for the fantastic job that they did and especially for being available to help no matter what was needed.

September

George Ostrouchov is receiving this award for leading the development of R infrastructure that puts ORNL on the world map as the place to go for big data analytics in R. He designed the architecture and leads the development of a series of R packages that provide a very high-level programming interface for distributed data analytics, literally "programming with big data" (pbd). The packages, branded with a "pbd" prefix, tightly couple distributed linear algebra libraries with R and engage the R community to develop more analytics for big data. This enables R to be a scalable analytics platform on OLCF resources. George also organized a recent R programming workshop at OLCF and brought an R mirror site to NICS.

The Scientific Data Group (SDG) is proud to have George lead analytics in its portfolio that includes the best talent for scientific data research from I/O through middleware to analytics and visualization. George also leads data analytics in the Remote Data Analysis and Visualization (RDAV) center at NICS.

October

Ross Bartlett served as release manager for the Limited Beta Release of the Virtual Environment for Reactor Applications (VERA) through the Radiation Safety Information Computational Center (RSICC). VERA is the simulation environment being developed for the Consortium for Advanced Simulation of Light-Water Reactors (CASL), the DOE Innovation Hub for Modeling & Simulation for Nuclear Energy. Although limited to current CASL partners, this is the first "official" release of VERA components, and is a precursor to wide deployment for use by industry, academia, and research institutions.

November

Clayton Webster joined the Computational Engineering & Energy Sciences group in CSMD in May of 2011 to develop the growing area of uncertainty quantification. FY12 proved to be an extremely productive year, in which Clayton produced 15 papers, a similar number of invited conference presentations, and organized or co-organized 6 symposia at international conferences (such as SIAM and SAMSI). In addition, he led or participated in 16 proposals, serving as Principal Investigator on six. Five of these have been funded, with 1 expected and 5 awaiting decisions.

This award particularly recognizes Clayton’s active involvement in development of industrial partnerships, including GE Global Research, Caterpillar, United Technologies, Pratt & Whitney, and most recently Proctor & Gamble. The Caterpillar and P&G interactions have recently borne fruit, resulting in additional funding for the growing UQ activities at ORNL.
