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 three computing divisions
(NERSC, Computational Research, and Information Technology), in the
formulation of Laboratory policy, and communicates Laboratory actions
on policy and procedures as appropriate. 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 used by 2,819 users at 540 institutions. Under
Horst’s leadership, NERSC has enabled important discoveries in
fields ranging from global climate modeling to astrophysics. Horst
is also the founding director of Berkeley Lab's Computational Research
which conducts applied research and development in computer science,
computational science, and applied mathematics.
Horst’s 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.
His 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.
