George
Delic, HiPERiSM Consulting, USA
George Delic majored in physics
for the B.S. (University of New South Wales) and
received a Ph.D. in theoretical physics (Australian
National University). He went on to establish a
career in computational physics that spanned work
at research and development centers in Europe and
the USA . After this, a tenured faculty appointment
followed with academic duties in service, teaching
and research. Delic’s research record of
more than 50 peer-reviewed publications demonstrates
a wide range of interests centered in advanced
numerical algorithms for high-performance computational
platforms. He has more than three decades of programmer/analyst
experience on serial, vector, Shared Memory Parallel
and Distributed Memory Parallel computer platforms.
After
arrival in the USA, Delic developed skills (and
a training program) in vector supercomputing
and published research on supercomputer workload
performance. He then entered into government
contracting where he acted as a Key Appointment
in establishing the U.S. EPA Scientific Customer
Support group at the EPA’s supercomputer
center. During this tenure Dr. Delic acted as
project lead in software development, conducted
outreach/training at customer sites, and organized/edited
technical conferences/proceedings on supercomputing
and high-performance algorithms for environmental
models.
Delic has applied his extensive experience in
government contracting to establish a consultancy
(HiPERiSM Consulting, LLC) that specializes in
technology transfer to enhance programmer skill
levels in OpenMP, MPI and hybrid OpenMP+MPI programming.
Specialized courses have sensitized stake-holders
in legacy codes to the need for code and performance
portability across current and future computer
architectures. The importance of software tools
and the programming environment as a whole have
been major components of the consultancy. Delic’s
current interests include, evaluation of compiler
performance, portability across parallel computer
architectures, and hybrid programming models that
match trends in clustered parallel computing.
Kent
Milfeld, TACC/University of Texas
at Austin, USA
Kent Milfeld received his Ph.D.
in Chemical Physics from the University of Texas
at Austin. After spending several years as a faculty
member at the University of Houston teaching chemistry
and numerical analysis, and serving as the director
for computational chemistry he moved to Austin,
Texas and joined the University of Texas HPC group
at the supercomputer center. Over the past 17 years
at the center, now named the Texas Advanced Computing
Center (TACC), Kent has occupied his time directing
the HPC training programs, teaching computational
chemistry, consulting, and collaborating on computational
projects such as GridChem
