Re: Advances in Numerical Methods for Large Sparse Sets of Lin Eqs.
12 April 1991
ABSTRACT. Titles of papers presented at "Advances in Numerical Methods
for Large Sparse Sets of Linear Equations", Keio University, 1 March
1991 are given.
These papers were presented in Japanese. However some papers are
available in English. For information about these contact the organizer,

who is an author of two papers presented here.
PAX is one of the longest running distributed memory projects in Japan
(since 1970s), and one of the few machines in the world for performing
quantum chromodynamics (another is at Columbia). Algorithms for linear
equations on PAX are described by a student of
