<BODY class=content text=#000000 bgColor=#ffffff><B>Top Researchers,
Accomplishments in High Performance Computing Honored at SC2003</B>
<P>Gordon Bell Awards, HPC& Bandwidth Challenges, Best Papers and Poster
Winners Announced</P>
<P>PHOENIX, Ariz (Nov. 21, 2003) - Top researchers and their unprecedented
accomplishments in high performance computing were recognized at the SC2003
conference this week, where the winners of the Gordon Bell Prizes, the HPC
Challenge, and the best research papers and poster were announced. SC2003, the
annual conference of high performance computing was held from November 15-21 in
the Phoenix Convention Center with the theme "Igniting Innovation."</P>
<P>Every year, SC2003 presents a wide range of awards that recognize the
innovative work of conference participants and leaders in the field. The
conference itself gives awards for Best Paper, Best Student Paper, Best Poster,
and the HPC Challenge and Bandwidth Challenge. In addition, SC2003 serves as the
venue for presenting the Gordon Bell Prizes, which reward practical uses of
high-performance computers, including best performance of an application and
best achievement in cost-performance. Additionally, two special awards are
presented by the Institute for Electrical and Electronic Engineers (IEEE) to
recognize longtime innovators in high-performance computing.</P>
<P>The 2003 IEEE Seymour Cray Award was presented to Burton J. Smith, chief
scientist for Cray Inc. The Seymour Cray Award honors individuals whose
innovative contributions to high performance computing systems best exemplify
the creative spirit demonstrated by Seymour Cray. Smith is a co-founder of Cray
Inc. and has been chief scientist and a director since early 1988. He is a
recognized authority on high performance computer architecture and programming
languages for parallel computers. He is the principal architect of the MTA
system and heads Cray's Cascade project. Smith was honored in 1990 with the
Eckert-Mauchly Award given jointly by the IEEE and the Association for Computing
Machinery, and was elected a fellow of both organizations in 1994. In February
2003 he was also elected as a member of the National Academy of Engineering.
</P>
<P>The IEEE's 2003 Sidney Fernbach Award as presented to Jack Dongarra, a
professor at the University of Tennessee and adjunct R&D participant at Oak
Ridge National Laboratory and adjunct professor at Rice University. The award,
established in 1992 in memory of Sidney Fernbach, one of the pioneers in the
development and application of high performance computers, is awarded for
outstanding contributions in the application of high performance computers using
innovative approaches. Dongarra, who is well-known for his work with the
twice-yearly ranking of the world's Top 500 supercomputers, specializes in
numerical algorithms in linear algebra, parallel computing, use of
advanced-computer architectures, programming methodology, and tools for parallel
computers. His research includes the development, testing and documentation of
high quality mathematical software. He has contributed to the design and
implementation of the following open source software packages and systems:
EISPACK, LINPACK, the BLAS, LAPACK, ScaLAPACK, Netlib, PVM, MPI, NetSolve, and
ATLAS.</P>
<P>The Gordon Bell Prizes are traditionally granted in three categories: special
accomplishment based on innovation; peak performance based on operations per
second; and a price per performance ratio measured in megaflop/s per dollar.
Winners depend on the entries received; in some years a prize is not awarded in
a given category. This year's Gordon Bell Prizes were for:</P>
<P><B>Peak Performance:</B> "A 14.6 Billion Degrees of Freedom, 5 Teraflop/s,
2.5 Terabyte Earthquake Simulation on the Earth Simulator." Authors: Dimitri
Komatitsch, Chen Ji, and Jeroen Tromp (California Institute of Technology); and
Seiji Tsuboi (Institute for Frontier Research on Earth Evolution, JAMSTEC). The
researchers used 1,944 processors of the Earth Simulator to model seismic wave
propagation resulting from large earthquakes. The model, based on a very
high-resolution mesh, incorporates wave speed and density structure,
three-dimensional wave-speed and density structure, ellipticity, topography, and
bathymetry.</P>
<P><B>Special Achievement:</B> "High Resolution Forward and Inverse Earthquake
Modeling on Terascale Computers." Authors: Volkan Akcelik, Jacobo Bielak,
Ioannis Epanomeritakis, Antonio Fernandez, Omar Ghattas, Eui Joong, Julio Lopez,
David O'Hallaron, and Tiankai Tu (Carnegie Mellon University); George Biros
(Courant Institute, New York University); and John Urbanic (Pittsburgh
Supercomputing Center). For earthquake simulations to play an important role in
the reduction of seismic risk, they must be capable of high resolution and high
fidelity. The researchers developed earthquake simulation algorithms and tools
and used them to carry out simulations of the 1994 Northridge earthquake in the
Los Angeles Basin using 100 million grid points.</P>
<P><B>Special Achievement ("lifetime"):</B> "Performance Evaluation and Tuning
of GRAPE-6—Towards 40 'Real' Tflop/s." Authors: Junichiro Makino and Hiroshi
Daisaka (Department of Astronomy, School of Science, University of Tokyo);
Eiichiro Kokubo (National Astronomical Observatory of Japan); and Toshiyuki
Fukushige (Department of General System Studies, College of Arts and Sciences,
University of Tokyo). The researchers benchmarked GRAPE-6, a sixth-generation
special-purpose computer for gravitational many-body problems, and presented the
measured performance for a few real applications with a top speed of 35.3
teraflops.</P>
<P>The SC2002 Conference also selected several outstanding award winners for
research papers and activities presented during the meeting.</P>
<P><B>Best Paper Award:</B> "The Case of the Missing Supercomputer Performance:
Achieving Optimal Performance on the 8,192 Processors of ASCI Q." Authors:
Fabrizio Petrini, Darren Kerbyson, and Scott Pakin (Los Alamos National
Laboratory). The researchers described how they improved the effective
performance of ASCI Q, the world's second-fastest supercomputer. Using an
arsenal of performance-analysis techniques including analytical models, custom
microbenchmarks, full applications, and simulators, they succeeded in observing,
identifying, and eliminating a serious—but previously undetected—performance
problem.</P>
<P><B>Best Student Paper:</B> "A New Parallel Kernel-Independent Fast Multipole
Method." Authors: Lexing Ying, George Biros, Denis Zorin, and Harper Langston
(New York University).</P>
<P><B>Best Student Poster:</B> "Improving the Performance of MPI Derived
Datatypes by Optimizing Memory-Access Cost." Authors: Surendra Byna and Xian-He
Sun (Illinois Institute of Technology, Chicago); William Gropp and Rajeev Thakur
(Argonne National Laboratory).</P>
<P>The HPC Challenge Awards recognize participants in two categories for
innovative uses of high performance computing resources. Those included:</P>
<P><B>The HPC Challenge Award for the Most Geographically Distributed
Application:</B> "Global Analysis of Arthropod Evolution," by Craig Stewart
(UITS, Indiana University), John Colbourne (Center for Genomics and
Bioinformatics, Indiana University) and their team.</P>
<P><B>The HPC Challenge Award for Most Innovative Data-Intensive
Application:</B> "Transcontinental RealityGrids for Interactive Collaborative
Exploration of Parameter Space (TRICEPS)," by Stephen Pickles (University of
Manchester), Peter Coveney (University College London) and their team. </P>
<P>SC2003 continues the 15-year Supercomputing Conference tradition of
highlighting the most innovative developments in high-performance computing and
networking. Bringing together scientists, engineers, researchers, educators,
programmers, system administrators and managers, SC2003 in Phoenix demonstrated
how these developments are sparking new ideas and new industries, as well as
rekindling older ones. The conference features the latest scientific and
technical innovations from around the world, while its SC Global events will
showcase achievements in the arts and sciences among dozens of remote
locations.</P>
<P>Next year, SC2004 will be held November 6-12 at the David L. Lawrence
Convention Center in Pittsburgh, Pennsylvania. The series of SC conferences is
sponsored by the Institute of Electrical and Electronics Engineers Computer
Society and by the Association for Computing Machinery's Special Interest Group
on Computer Architecture.</P></BODY></HTML>
