I wish to welcome all of you to the International Symposium on High
Perf- mance Computing 2000 (ISHPC 2000) in the megalopolis of Tokyo.
After having two great successes with ISHPC'97 (Fukuoka, November 1997)
and ISHPC'99 (Kyoto, May 1999), many people have requested that the
symposium would be held in the capital of Japan and we have agreed. I am
very pleased to serve as Conference Chair at a time when high p-
formance computing (HPC) has a signi?cant in?uence on computer science
and technology. In particular, HPC has had and will continue to have a
signi?cant - pact on the advanced technologies of the "IT" revolution.
The many conferences and symposiums that are held on the subject around
the world are an indication of the importance of this area and the
interest of the research community. One of the goals of this symposium
is to provide a forum for the discussion of all aspects of HPC (from
system architecture to real applications) in a more informal and
personal fashion. Today we are delighted to have this symposium, which
includes excellent invited talks, tutorials and workshops, as well as
high quality technical papers.
