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

Box Leangsuksun, Louisiana Tech University, USA

Chokchai “Box” Leangsuksun is an associate professor in computer science and in the Center for Entrepreneurship and Information Technology (CEnIT) at Louisiana Tech University. He received a Ph.D. and M.S. in computer science from Kent State University, Kent, Ohio, in 1989 and 1995 respectively.

His research interests include:

  • Highly reliable and high-performance computing
  • Intelligent component based software engineering
  • Parallel and distributed computing
  • Service engineering and management

Before joining Louisiana Tech University in early 2002, Leangsuksun was a member of Technical Staff, Lucent Technologies-Bell Labs Innovation, from 1995-2002 and was responsible in many key research and development roles in various strategic products. Within a short time, he has established his name and research recognitions by founding and co-chairing a high availability and performance workshop, serving as program committee in various conferences/workshops (e.g. IEEE Cluster, Grid Computing Education), releasing the first HA-Beowulf cluster software, writing articles featured in major technical journals/magazines, and giving presentations in highly regarded conferences. He has also collaborated with various research groups and national and industrial labs, which include Oak Ridge National Lab, NCSA, LAM/MPI, Dell, Intel, and Ericsson.

In March 2004, he released the HA-OSCAR beta version, which was the first field-grade High Availability and Performance Beowulf cluster with transparent recovery. The release has attracted considerable interest from the HPC research and industry community.
