SciDAC Meeting to Showcase LBNL’s Leadership in Projects

May 1, 2005

Since DOE launched its Scientific Discovery through Advanced Computing (SciDAC) program in 2001, scientists at Berkeley Lab have led a number of the projects and provided strong support for many others.

When the annual SciDAC meeting is held June 26–30 in San Francisco, LBNL’s con- tributions to the success of the program will be highlighted via invited talks, panel dis- cussions and poster presentations. Here is a rundown of Berkeley Lab contributions to the meeting program.

Invited talks:

• “Spatial Modeling in Systems Biology,” Phil Colella, CRD • “New Approaches to Fast Electron Correlation Methods,” Martin Head- Gordon, Chemical Sciences Division/UC Berkeley

• “Numerical Simulation of Laboratory- Scale Premixed Turbulent Flames,” Marc Day, CRD

• “The Future of Numerical Linear Algebra Libraries, Automatic Tuning of Sparse Matrix Codes, the Next LAPACK and ScaLAPACK,” Jim Demmel, CRD/UC Berkeley • “Solving Large-Scale Eigenvalue Problems in SciDAC Applications,” Chao Yang, CRD

Poster presentations:

“SciDAC Advances and Applications in Computational Beam Dynamics,” Robert Ryne, Accelerator and Fusion Research Division

 • “Cartesian Grid Embedded Boundary Methods for Problems with Complex Geometries,” Daniel Graves, CRD

• “The Roles of Sparse Direct Methods in Large-Scale Simulations,” Xiaoye “Sherry” Li, CRD

• “Adaptive Mesh Refinement for Particle-in-Cell Methods,” David Serafini, CRD

• “An Efficient Indexing Technology for Accelerating Data Intensive Science,” Kesheng “John” Wu, CRD

Panel presentations:

• Rob Ryne of LBNL’s Accelerator and Fusion Research Division will present the High Energy/Nuclear Physics perspective in a panel discussing “SciDAC II: The Shape of Things to Come.”

• Lenny Oliker of CRD will discuss “The NERSC Benchmark Suite” in a panel session looking at “SciDAC II: Perspectives on Hardware and Software Infrastructure.”

About Computing Sciences at Berkeley Lab

The Lawrence Berkeley National Laboratory (Berkeley Lab) Computing Sciences organization provides the computing and networking resources and expertise critical to advancing the Department of Energy's research missions: developing new energy sources, improving energy efficiency, developing new materials and increasing our understanding of ourselves, our world and our universe.

ESnet, the Energy Sciences Network, provides the high-bandwidth, reliable connections that link scientists at 40 DOE research sites to each other and to experimental facilities and supercomputing centers around the country. The National Energy Research Scientific Computing Center (NERSC) powers the discoveries of 7,000-plus scientists at national laboratories and universities, including those at Berkeley Lab's Computational Research Division (CRD). CRD conducts research and development in mathematical modeling and simulation, algorithm design, data storage, management and analysis, computer system architecture and high-performance software implementation. NERSC and ESnet are Department of Energy Office of Science User Facilities.

Lawrence Berkeley National Laboratory addresses the world's most urgent scientific challenges by advancing sustainable energy, protecting human health, creating new materials, and revealing the origin and fate of the universe. Founded in 1931, Berkeley Lab's scientific expertise has been recognized with 13 Nobel prizes. The University of California manages Berkeley Lab for the DOE’s Office of Science.

DOE’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. For more information, please visit science.energy.gov.
