Keynotes
Horst Simon, NERSC/LBNL,
USA
Dr. Horst Simon was named Associate Laboratory Director (ALD) for Computing
Sciences at Berkeley Lab in 2004. In his role as the ALD for Computing Sciences,
Horst represents the interests of the Lab’s scientific computing divisions,
NERSC and Computational Research, in the formulation of Laboratory policy,
and leads the overall direction of the two divisions. He also coordinates
constructive interactions within the computing sciences divisions to seek
coupling with other scientific programs.
Horst joined LBNL in early 1996 as director of the newly formed NERSC Division,
and was one of the key architects in establishing NERSC at its new location
in Berkeley. The NERSC Center is DOE’s flagship supercomputing facility
for unclassified research funded by DOE’s Office of Science and is
currently supports 2,677 users at more than 300 institutions. Under Horst’s
leadership, NERSC has enabled important discoveries in fields ranging from
global climate modeling to combustion to astrophysics. Horst is also the
founding director of Berkeley Lab's Computational Research Division, which
conducts applied research and development in computer science, computational
science, and applied mathematics. His research interests are in the development
of sparse matrix algorithms, algorithms for large-scale eigenvalue problems,
and domain decomposition algorithms for unstructured domains for parallel
processing.
Horst's recursive spectral bisection algorithm is regarded as a breakthrough
in parallel algorithms for unstructured computations, and his algorithm research
efforts were honored with the 1988 Gordon Bell Prize for parallel processing
research. Horst was member of the NASA team that developed the NAS Parallel
Benchmarks, a widely used standard for evaluating the performance of massively
parallel systems. He is also one of four editors of the twice-yearly “TOP500” list
of the world’s most powerful computing systems.
Norman L. Miller, Lawrence
Berkeley National Laboratory, USA
Norman L. Miller's research focuses on understanding hydroclimate processes
and related impacts based on modeling and analysis of regional climate, hydrology,

quality, agriculture, and impacts to other sectors of society. His research
includes conceptual models, numerical code development and evaluation, statistical
analyses of historical and projected global and regional climate, numerical
weather and streamflow ensemble prediction, seasonal forecasts, and scaling
theories.
Miller uses remote-sensed observations, reanalysis data, and IPCC AOGCM projections
as input forcing to his limited area models and statistical downscaling schemes
to understand climate and impacts at site-to-regional scales. He also leads
