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.

Rockie Ricks [EMAIL PROTECTED] ------------------------------ From: Alex Mutasingwa <[EMAIL PROTECTED]> Date: Wed, 15 Dec 1999 12:01:40 JST Subject: Unsteady Open Channel Flow 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. I advance my thanks Alex G Mutasingwa.

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 The conference is organized jointly by DFG-Sonderforschungsbereich 359, Heidelberg University Institute of Information Technology, Vietnam NCST Institute of Mathematics, Vietnam NCST Institute of Mechanics, Vietnam NCST Interdisciplinary Center for Scientific Computing Heidelberg (IWR) Hanoi University of Natural Sciences Hanoi University of Technology Ho Chi Minh City University of Technology SCIENTIFIC COMMITTEE ORGANIZING COMMITTEE P.

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. SIAM invites applications from advanced undergraduate and graduate students and postdocs in applied mathematics and computational science.
