The New BLAS Standard. The BLAS (Basic Linear Algebra Subroutines) Standards Committee has reconvened to consider adding new functions requested by different user communities, including batched BLAS (eg many small or medium sized matrix multiplications done at once), low precision BLAS, and reproducible BLAS (bitwise reproducible results, independent of number of processors, summation order, etc).
The ASPIRE project (Algorithms and Specializers for Provably Optimal Implementations with Resilience and Efficiency) is motivated by the transition from a post-transistor-scaling world to one where whole-stack codesign is the key to improved efficiency. It follows on the ParLab (Parallel Computing Laboratory), an interdisciplinary research center motivated by the multicore revolution.
The Complexity of Accurate Floating Point Computation. See below for recent talks.
Proposal to update the LAPACK and ScaLAPACK linear algebra libraries, in pdf or postscript.
CITRIS is the Center for Information Technology Research in the interest of Society, a new $300M multicampus research center with the mandate of creating information technology to tackle society's most critical needs. Initial CITRIS research will focus on energy efficiency, transportation, disaster response, health care, education and environmental monitoring.
SUGAR is a simulation tool for MEMS (MicroElectroMechanical Systems), tiny sensors and actuators that form a pillar of CITRIS's approach to solving large scale societal problems. SUGAR is used by many researchers in the Berkeley Sensor and Actuator Center (BSAC).
BeBOP is Berkeley Benchmarking and OPtimization Group. We work on automatic performance optimization of numerical kernels, tuning them to run as fast as possible for particular architectures and sometimes particular inputs.
Millennium is a campus-wide project to provide hardward and sofware facilities for high performance computing. My activities are to provide algorithms, software and advice to best facilitate computational science and engineering on campus.
Templates for the Solution of Algebraic Eigenvalue Problems:
This book gives a unified overview of the theory, algorithms and
practical software for eigenvalue problems. It organizes this large
body of material to make it accessible for the first time to experts
and non-experts who need to choose the best state-of-the-art algorithms
and software for their problems.

Building Blocks for Iterative Methods is a hyper-text book on
iterative methods for solving systems of linear equations.
A similar book project for eigenvalue problems is underway.
In Fall 08 we started a New Graduate Designated Emphasis in Computational Science and Engineering (CSE), which operates as a "graduate minor". Over 100 faculty from 20 departments and programs are participating.
