- Sep 1996 - Present Computing Systems Engineer
- National Energy Research Scientific Computing (NERSC)
- One of the lead software developers and coordinators for
NERSC Information Management (NIM) system.
The NIM Central Account Management (CAM) Client/Server developer
with over 20,000 lines of code.
A key member of the NIM database architect team.
- Often called upon, on behalf of NERSC,
for specialized software projects.
- Was responsible for installation, testing, documentation, training,
and use of physics applications on behalf of the user services
- Software project leader for the User Services group - was responsible
for general software installation, testing, documentation, and
establishing software acquisition and retirement policies.
- Jan 1991 - Aug 1996 Consultant - Sterling Software -
NASA/Ames Research Center
- Responsible for installation, testing, documentation, training,
and use of mathematical packages
on the Aeronautics Consolidated Supercomputing Facility (ACSF)
and Numerical Aerodynamic Simulation Program (NAS)
Cray supercomputers (Y-MP, C90) and IBM SP2 160 node parallel machine
for Sterling Software,
a contractor for NASA/Ames Research Center.
- Proposed, developed, and taught courses on numerical methods for
computers covering such topics as: computational precision and accuracy,
Chebychev polynomials, function and B-spline interpolation,
FFT, wavelet algorithms, and fuzzy logic.
These courses were well received by the participants
as were the courses I taught regarding Cray Fortran vectorization &
optimization, and math libraries.
- Developed several tools for using and monitoring subroutine
libraries in a UNIX environment.
This allowed detailed information concerning math library usage for the
- Wrote a debugging utility of 2500 lines of code that isolates which
program modules are producing erroneous results.
It is mostly used to isolate which modules are adversely affected by
compiler optimization options.
- Wrote a work-duty scheduler program based on the Monte-Carlo
Metropolis algorithm (5000 lines of code).
This scheduler aids with scheduling any number of
consultants with individual constraints.
- Jun 1984 - Dec 1990 Graduate Research Assistant -
- Performed doctoral research
in Monte Carlo solutions of electronic Hamiltonians for
small alkali metal clusters at the University of
California, Berkeley and Lawrence Berkeley Laboratory.
- Formulation of specific research goals,
familiarity with current literature,
development of computational research tools on various
machines and system environments (e.g. Cray-CTSS, VAX-VMS,
PC-DOS, UNIX), analysis and evaluation of results,
presentation of results to research groups and conferences,
and preparing documentation and publication.
- Wrote a 11,000 line vectorizing Fortran code (30% comments) and a
dozen or so associated programs in Fortran and `C'.
These codes allowed quicker analysis and larger molecular systems than
- Other duties included training and supervision
of undergraduate assistants and beginning graduate research
assistants, coordination of efforts amongst
peers, recommendation and maintenance of system
- Summers 1982 & 1983
Graduate Research Assistant Technician -
Accelerator Technology Division - Los Alamos National Laboratory
- Work involved the research of staggered-tuning
in linear accelerator design to decrease the overall beam
dispersion and emittance; thereby, increasing the peak particle
flux at target.
- Other work included the design and development of a linear
accelerator cost database
to minimize total projected lifetime expenditures,
considering construction and power consumption
for a given RF tube component and design specification.
- Jun 1979 - Dec 1980 Nuclear Physics Data Analyst -
University of Minnesota
- Responsible for nuclear scattering data acquisition and analysis
at the Clinton P. Anderson Meson Physics Facility (LAMPF) and data analysis
at the Univ. of Minnesota for the dept. of Physics nuclear research group.
- Accomplishments were the exhaustive analyses of
208Pb, 24Mg, 19F,
182W, 184W, 186W
and theoretical fits of 208Pb.
- The work included design and implementation of data handling and
plotting systems to aid in theoretical studies.
