Subject: MPI in SIAM

NA Digest readers might be interested to learn that MPI is not only
a system for parallel computing, it is also a language in SIAM (the
country, not the professional society).

Subject: Solving Large Eigenvalue Problem

Hi,

I'm looking for an efficient solver for the generalized eigenvalue
problem
H*x = lambda*B*x

with very large matrices H and B (n > 10000). Since the problem is
that large, standard packages like LAPACK aren't able to solve it.

Here H (Hamiltonian matrix, nxn, symmetric but not sparse) and B
(overlap-matrix, nxn, symmetric and sparse) are calculated by some
quantum and quasi-quantum chemical calculations. The elements of H
are sums of the kinetic and potential integrals using gaussian product
functions as basisfunctions. the integrals of the potential matrix
were calculated using standard potential functions, like the harmonic
oscillator potential function. this matrix is therefore not sparse.
The kinetic integrals were calculated by using the quantum chemical
kinetic operator.

Subject: Oxford University Press Monograph Series

OXFORD UNIVERSITY PRESS
NUMERICAL MATHEMATICS AND SCIENTIFIC COMPUTATION

Series Editors: G H Golub (Stanford University)
R Jeltsch (ETH Zurich)
W A Light (Leicester University)
K W Morton (University of Oxford)
E Suli (University of Oxford)

Stimulated by recent developments in the field of mathematical modelling
and its increasing impact on scientific computation, Oxford University
Press has re-launched its classic monograph series in numerical analysis
which included Wilkinson's celebrated treatise "The Algebraic Eigenvalue
Problem". As the new name, Numerical Mathematics and Scientific Computation,
already suggests, the series will now aim to cover the broad subject area
concerned with theoretical and computational aspects of modern numerical
mathematics.

What are the developments that have changed numerical analysis and which
will feature in the new series? Firstly, there is the increasing power
and availability of computer workstations and the widespread feasibility
of complex numerical computations; secondly, there are the expanding
demands of mathematical modelling; and thirdly, there is the growing
sophistication of the mathematical theory applied to the formulation and
the analysis of numerical methods, and the related fact that numerical
analysis now generates research into relatively abstract mathematics.

If you have an idea for a book in this new series, please write or e-mail
to any of the Editors or to the Publishers. Oxford University Press will
collaborate with authors to ensure that their proposals are evaluated very
quickly in constructive manner, produced to high standard, and promoted
and distributed worldwide.

Issues 15 and 47], CERFACS in Toulouse (France) is organizing an International
Linear Algebra Year (ILAY) from September 1995 to September 1996.

The last ILAY workshop will be held at the UNESCO Centre in Toulouse
