DESCRIPTION

The International Symposium on Supercomputing --- New Horizon of
Computational Science will be held on September 1-2, 1997 at the
Science Museum in Kitanomaru Park, downtown Tokyo. It will be held in
celebration of 60th birthday of Professor Daiichiro Sugimoto, who has
been leading the theoretical and computational astrophysics for three
decades (for his personal profile and scientific work, please see the
separate sheets).

The purpose of this symposium is to explore the computational science
in the Tflops era, which is pioneered by Professor Sugimoto's GRAPE
project. First, we review the present status and prospect in near
future in large scale simulations in various scientific fields, such
as astrophysics, molecular dynamics, fluid mechanics, and lattice
quantum chromo dynamics. We also discuss hardware and software
technologies to open the door to Tflops era. They include the design
and development of high-performance special-purpose computers and
parallel processing algorithms.

Symposium will consist of plenary talks with 45 minutes and
contributed papers with 15 minutes talks or poster
presentations.

About Professor Daiichiro Sugimoto

Professor Sugimoto has been one of the leading researchers in
theoretical and computational astrophysics. His early work centered on
Stellar evolution. He invented the Sugimoto method, which is
extensively used by himself and his collaborators to study the stellar
evolution in the regime where thermal and dynamical effects are both
important.  Using this code, he intensively investigated shell flashes
in the shell burning layer of evolved stars and compact objects, 
electron capture, supernova explosions, and the evolution of compact
binary systems.

In 1980s, he shifted his main interest to the dynamical evolution of
star clusters. He investigated the post-collapse evolution of globular
clusters using a fluid approximation and established the concept of
gravothermal oscillations.  In 1989, he started the development of
GRAPE (GRAvity PipE), special purpose computers for the simulations of
gravitational many-body systems, such as a star cluster or galaxy. In
the summer of 1995, he and his collaborators completed the GRAPE-4,
the first Teraflops computer for scientific simulation.

GRAPE-4 was an overwhelming success. The simulation with GRAPE-4
beautifully proved the existence of gravothermal oscillations in
globular clusters. The success of the GRAPE project is not just to
advance the understanding of stellar dynamics. It also opens a new
approach to Computational Science with special purpose computers. The
international symposium "New Horizon of Computational Science" is
held in celebration of the 60th birthday of Professor Sugimoto.
