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.”
