Subject: Pre-conditioner for CG method

Has there been any thing published using the following
pre-conditioner M for the conjugate gradient method?
Suppose we have the usual Laplace model problem Ax=b
and the proposed preconditioner is M: (call it 'prod' preconditioner)

n=...
n2=sqrt(n);
f=0.25;
c=1.25; % 1<c<2
a1= f*(diag(ones(n-1,1),1)+diag(ones(n-1,1),-1));
an= f*(diag(ones(n-n2,1),n2)+diag(ones(n-n2,1),-n2));
for i=n2:n2:n-n2; a1(i,i+1)=0; a1(i+1,i)=0; end;

A=eye(n)-a1-an;
M=(eye(n)-c*a1)*(eye(n)-c*an);

Omitting the Conjugate Gradients code (in FORTRAN anyway) we
find for n=149769 that
iterations =61 c=1.963 (optimal)
cf
iterations=308 for c=1 'prod' preconditioner,
iterations=744 for no preconditioner,
iterations=69 for Modified Incomplete Cholesky preconditioner.

NA-Net colleagues,

I am doing PhD research on unsteady open channel flow, specifically for
rivers, in Hiroshima University.

My research now is 2-Dimensional computation of flood propagation in an
experimental channel which is a Meandering(sine generated) Compound
channel.I am faced with problems of handling the interface between main
channel and flood plains, and also the zero depth problem.

When the flow is only in the main channel, there is no problem with my
program which employs Explicit Maccomark Scheme. When the flow rises
above bankful the interface between main channel and flood plains brings
oscillations in computed values and the computation breaks.

Could you advice me on how I can tackle these problems.

Alex G Mutasingwa.

Subject: Conference in Vietnam on Scientific Computing

CONFERENCE ON HIGH PERFORMANCE SCIENTIFIC COMPUTING
March 27-31, 2000
Hanoi, Vietnam

CALL FOR PAPERS AND REGISTRATION INFORMATION

High Performance Scientific Computing (HPSC) is an interdisciplinary
area that combines many fields such as mathematics, computer science
and scientific and engineering applications. It is a key high-technology
for competitiveness in industrialized countries as well as for speeding
up development in emerging countries.

HPSC develops methods for computer aided simulation and optimization for
systems and processes. In practical applications in industry and commerce,
science and engineering, it helps to save resources, to avoid pollution,
to reduce risks and costs, to improve product quality, to shorten
development times or simply to operate systems better.

High performance in HPSC can mean highly efficient algorithms and software
as well as high computing power of the hardware, e.g. parallel systems.

TOPICS
include, but are not limited to...

- mathematical modelling
- numerical simulation
- methods for optimization and control
- parallel architectures
- parallel programming
- symbolic computing
- software development
- applications of Scientific Computing in
environmental and hydrology problems
physics, mechanics and chemistry
transport, logistics and site location
communication networks, production scheduling
energy management, investment strategies
industrial and commercial problems

Subject: SIAM/AAAS Mass Media Science and Engineering Fellows Program

SIAM/AAAS MASS MEDIA SCIENCE AND ENGINEERING FELLOWS PROGRAM

This program supports a fellowship in the AAAS Mass Media Science
and Engineering Fellows Program.

For a 10-week period in the summer, the AAAS Mass Media Science and
Engineering Fellows Program places advanced students in the natural
and social sciences and engineering at radio stations, television
stations, newspapers, and magazines throughout the United States.

The goal of the program is to strengthen the connections between
science and the media. The fellowship provides scientists and
engineers opportunities to: (1) observe and participate in the process
by which events and ideas become news; (2) improve their communication
skills by learning to describe complex technical subjects in a manner
comprehensible to nonspecialists; and (3) increase their understanding
of editorial decision making and the way in which information is
effectively disseminated. This program is for students pursuing
degrees in the natural and social sciences and engineering. Students
majoring in English, journalism, science journalism, or other
nontechnical fields are not eligible for these fellowships.

SIAM WILL SPONSOR ONE STUDENT FOR A AAAS MASS MEDIA SCIENCE AND
ENGINEERING FELLOWSHIP FOR THE SUMMER OF 2000.
