Jaydeep Bardhan Receives Howes Scholar Award in Computational Science

Dr. Jaydeep Bardhan of Argonne National Laboratory has been named a Frederick A. Howes Scholar in Computational Science for 2007. Bardhan was one of two former CSGF fellows presented with the award at the 2007 CSGF Annual Fellows' Conference in Washington, D.C., June 19-21.

The award was established to honor the late Frederick Anthony Howes, who managed the Applied Mathematical Science Program in the U.S. Department of Energy during the 1990s and oversaw the DOE Computational Science Graduate Fellowship (CSGF) program. Only CSGF fellows are eligible for this prestigious award, and only one or two are named each year.

Bardhan was a CSGF fellow from 2002 to 2006 and spent a summer at Argonne in 2003 under that program. He received his Ph.D. in electrical engineering and computer science from MIT in 2006. He is currently a Wilkinson Fellow at Argonne.

Bardhan's research focuses on biomolecular modeling, an emerging area that demands expertise in engineering, numerical methods, biology, and high-performance computing. Among his accomplishments are the development of a novel technique for analyzing the interactions between protein
molecules and the formulation of new approaches for determining optimal molecular targets for drug design.

IBM Triples Performance of World

IBM today announced Blue Gene/P, the second generation of the world's most powerful supercomputer. Blue Gene/P nearly triples the performance of its predecessor, Blue Gene/L - currently the world's fastest computer - while remaining the most energy-efficient and space-saving computing package ever built.

Access Grid Wins R&D 100 Award

Researchers in the Mathematics and Computer Science Division at Argonne National Laboratory have won an R&D 100 award for Access Grid 3.0: Group Collaboration Software. The award is given annually by R&D magazine to the year's most technologically significant new products.

Access Grid 3 software enables groups of people to collaborate using open source standards and Internet technology. The Access Grid environment is designed to provide a natural feel, where users can see and hear one another, projected on a large display wall. More than just videoconferencing, the Access Grid enables participants to share and interact with files and applications. The open nature of the Access Grid software has attracted thousands of users from around the world and encouraged numerous commercial and research institutions to extend the software for their purposes.

Two Papers by Argonne Researchers Selected as "Outstanding" in the EuroPVM/MPI Users

Two papers by Argonne researchers have been selected as "Outstanding Papers" in the 14th annual EuroPVM/MPI Users' Group conference. The first paper, "Self-consistent MPI Performance Requirements" by Jesper Larsson Traff, William Gropp, and Rajeev Thakur, presents conditions that can be used by benchmarks and tools to automatically verify whether a given MPI implementation fulfills basic performance requirements.

The second paper, "Test Suite for Evaluating Performance of MPI Implementations That Support MPI_THREAD_MULTIPLE" by Rajeev Thakur and William Gropp, presents performance tests that can be used to measure the overhead of providing the MPI_THREAD_LEVEL of thread safety for user programs. EuroPVM/MPI 2007, which will take place October 1-3, 2007, provides a forum for users and developers of PVM, MPI, and other message-passing programming environments.

NEOS provides state-of-the-art optimization software over Internet

Optimization technology is essential to engineers, scientists, businesses and even students. Optimization programs provide the answers to questions ranging from creating the most efficient allocation of resources to finding the healthiest meal at a fast food restaurant. But writing program after program to solve one optimization problem after another or even using an existing optimization library is often time-consuming or tedious.

To address this issue, researchers at the U.S. Department of Energy's Argonne National Laboratory – in conjunction with researchers at Northwestern University– developed the Network-Enabled Optimization System (NEOS), which provides state-of-the-art numerical optimization software over the Internet. The system has become such a success that it currently leads the field in the number of users at Department of Energy labs.

Argonne Wins Three R&D 100 Awards for Innovative Technologies

The Access Grid is one of three Argonne projects to win R&D Magazine's prestigious award this year. Access Grid 3 software enables groups of people to collaborate using open- source standards and Internet technology. The Access Grid is designed to provide a natural virtual environment, where users can see and hear one another, projected on a large display wall. More than just videoconferencing, the Access Grid enables participants to share and interact with files and applications. The open nature of the Access Grid software has attracted thousands of users from around the world and has encouraged numerous commercial and research institutions to adopt the software for their purposes.

Picture This: Visualization as a Tool for Data Analysis

As science becomes increasingly digitized and data-based, visualization is set to become more and more important. Using visualization, Gaither and Papka can help scientists from all fields: medical science, cosmology, computational fluid dynamics, architecture, geosciences and meteorology.

The biggest challenges, according to both Papka and Gaither, are visualizations of very abstract systems. In such cases collaborating with scientists and learning about the research domain is crucial to creating useful visualizations.

Mihai Anitescu Presents a Semi-Plenary Address at ICCOPT

Mihai Anitescu, a computational mathematician at Argonne National Laboratory, will present a semi-plenary address at the Second Mathematical Programming Society International Conference on Continuous Optimization August 13-16, 2007, in Hamilton, Ontario. ICCOPT, held every three years, is the world's most prestigious conference in continuous optimization.

Anitescu's presentation,"Emerging Design Challenges in the Advanced Nuclear Fuel Cycles," will address the challenges and Argonne's recent results in optimization of complex systems and in particular optimization of the advanced nuclear fuel cycle.
