Experience
Dr. Simon is currently director of the National Energy Research Scientific
Computing (NERSC) Division and of the
Computational Research Division (CRD)
at Lawrence Berkeley National Laboratory.
He has overall responsibility for a $42M budget with staff of about 200.
The NERSC Division consists of a unique, national high performance computing
facility, the NERSC Center. The CRD Division has research programs in a
wide variety of computer science and computational science areas. Established
in 1974 at Lawrence Livermore National Laboratory, the NERSC center was
moved to Berkeley Lab in 1996 with a goal of increased interactions with
the UC Berkeley campus. The center is funded by the U.S. Department of
Energy's Office of Science. NERSC currently serves about 2,000 users at
national labs, universities and industries across the country, and is engaged
in a a large number of research projects in computer and computational
science. Simon took over as director of NERSC in 1996. During his tenure
at NERSC, the center moved to a new location, completely rebuilt its staff,
transitioned to highly parallel platforms, and integrated computer and
computational science activities. NERSC provides state-of-the-art
computational services, and currently houses a 10 Tflop/s IBM RS/6000
SP supercomputer with more than 6000 processors, one of the largest openly
accessible resources for basic research in computational science.
The Computational Research Division (CRD) creates computational tools
and techniques that enable scientific breakthroughs, by conducting applied
research and development in computer science, computational science, and
applied mathematics. CRD conducts research and development in mathematical
modeling, algorithmic design, software implementation, and system architectures,
data management, visualization, networking, and grid middleware, and evaluates
new and promising technologies. Dr. Simon is also responsible for direct
collaborations with scientists, in fields ranging from nano science and
computational biology to climate modeling to astrophysics.
From 1994 to 1996 Dr. Simon was with the Advanced Systems Division of
Silicon
Graphics. As Research Market Development Manager he interacted with
users of SGI platforms in the academic and research laboratory environment.
His mission was to establish long term mutually beneficial relationships
between SGI and the advanced scientific computing user community, helping
SGI developers to understand the requirements of a rapidly changing market,
and helping researchers to bring the best computational solutions to bear
on their problems.
From 1989 to 1994, Dr. Simon worked for Computer
Sciences Corporation as manager of a research department supporting
the NAS (Numerical Aerodynamic Simulation)
Systems Division at NASA Ames Research
Center in Moffett Field, California. In this role was is responsible
for researchers in three groups in the areas of parallel algorithm development,
scientific visualization and numerical grid generation. The overall mission
of this group was to advance the use of high performance computing in large-scale
Computational Aeroscience (CAS) applications for the benefit of the US
aeronautics and High Performance Computing communities. Activities of the
group are in the areas of algorithm research, scientific software, and
advanced user interfaces. Dr. Simon's responsibilities included the evaluation
of new parallel hardware, and benchmarking support for testbed systems.
He was responsible for the initiation of innovative research projects in
the research areas of his department. He also coordinated aspects of the
external relations of the NAS projects, such as collaboration with researchers
in industry and academia, a visitor program, and grants and subcontracts.
Previously, until October 1989, Dr. Simon was an employee of Boeing
Computer Services, and from October 1987 through October 1989, supported
the NAS project in a similar capacity. In addition to the NAS research
work, he supported Boeing technical marketing work in the Bay Area. In
this function he collaborated with General Electric in the development
of a joint Boeing/GE proposal for supercomputer center management at NASA
Ames Research Center. His main task was the development of the applied
research component of the proposal, dealing with implementation of a research
program in the utilization of parallel processing technology for computational
fluid dynamics.
Prior to assuming the position at NASA Ames, Dr. Simon was the manager
of the Computational Mathematics Group of Boeing Computer Services (from
July 1986 to October 1987). This group had responsibility for the maintenance,
development, and certification of all mathematical
and statistical software libraries resident on BCS computing centers
nationwide, which included over 500 million dollars of computing mainframes,
including the then state-of-the art CRAY X-MP/24. The group was part of
the Engineering Technology Applications Division which had a commercial
charter to market analytical services to both government agencies and the
private sector.
Dr. Simon was also project manager for the internal Boeing research
program "Algorithms forAdvanced Architectures" funded by the Boeing High
Speed Computing Center (HSC). The goal of the HSC is to transfer advanced
technology in the areas of algorithm research, software development, and
parallel and vector architectures into the engineering departments of the
Boeing Company. Other responsibilities of Dr. Simon at Boeing included
project management for the NSF research project "Effective
Tools for Scientific Computing on Supercomputers", and the AFOSR Contract
"Sparse Matrix Methods on Vector and Parallel Computers". He was also responsible
for proposal development and program coordination for the National Science
Foundation Supercomputing Summer Institutes 1985 and 1986.
Dr. Simon joined Boeing Computer Services in 1983. He coordinated the
involvement of the BCS Engineering and Technology Applications Division
(ETA) in the Phase I of the supercomputing initiative of the National Science
Foundation. In this function, he was responsible for organizing the consultation
for NSF grantees in matters such as vectorization and optimization of application
programs on supercomputers, and for initiating joint research projects.
He also gave introductory lectures on supercomputer applications at national
meetings.
From 1982 to 1983 Dr. Simon was an assistant professor at the Department
of Applied Mathematics, SUNY Stony Brook, New York. During his graduate
studies at the University of California, Dr. Simon worked as a research
assistant for the Center of Pure and Applied Mathematics and for the Electronics
Research Laboratory, Berkeley, developing mathematical software. He also
consulted for the Applied Mechanics Research Laboratory at Lockheed Missiles
and Space Company, Palo Alto, on a new method for solving symmetric indefinite
linear systems.
Research Interests
One of Dr. Simon's research interests is in the development and application
of high performance linear algebra algorithms. Currently he is investigating
the use of techniques based on singular value decomposition and eigenvalue
analysis to applications in information retrieval, web link analysis,
and clustering. At NERSC he was also leading the project on "Sparse
Linear Algebra Algorithms for MPPs", which resulted in scalable implementation
of the Lanczos algorithm, approximate inverse preconditioners, and dynamic
partitioning. His continued areas of interest are
sparse
matrix algorithms, algorithms for large scale eigenvalue problems,
and domain decomposition
algorithms for unstructured domains for parallel processing. Dr. Simon's
algorithm research efforts were honored with the 1988 Gordon Bell Prize
for parallel processing research. Software based on his "recursive
spectral bisection algorithm" has been widely distributed to the finite
element research community, and is regarded a major breakthrough in parallel
algorithms for unstructured computations.
A second area of interest is in performance analysis of high performance
computing architectures, and the assessment of supercomputing technology.
Dr. Simon has been involved with the TOP500
effort almost since its beginning. He was member of the NAS team which
developed the NAS Parallel Benchmarks,
which has become an accepted standard for performance evaluation of MPP
systems. Dr. Simon has been invited speaker at a large number of national
and international conferences. He has given tutorials on high performance
computing at many of the Supercomputing XX conferences as well as on many
other occasions.
