Liber Amicorum Piet van der Houwen

On Friday October 22, 2000 a farewell symposium was organised

at CWI Amsterdam for Piet van der Houwen at the occasion of his retirement

after a tenure of 36 years at CWI and 24 years at the University

of Amsterdam. At this occasion, a Liber Amicorum was presented to Piet.

This book, among others, lists Piet's seventeen PhD students with the

titles of their doctor's theses and Piet's 187 publications

(books, journal and proceedings papers) so far.

Apart from thirty-three contributions of a personal nature, the book contains

the following seven more scientific contributions:

Herman Brunner, Volterra integral equations at MC and CWI: 1976 to 2000

Jan de Groot, A fundamental differential equation in electron-gun design

Willem Hundsdorfer, A linearly-implicit scheme which damps only where it should do so

Felice Iavernaro, Francesca Mazzia, and Donato Trigiante, Phantoms and ghosts

Marc Spijker, Aspects of stability in numerical initial value problems

Piet Wesseling, Stability conditions for the convection-diffusion equation

using the SHK Runge-Kutta method

Fred Wubs, RK and MRILU

The contributions by Hermann Brunner and Marc Spijker are the reflections

of their talks during the symposium.

**Subject: Seeking MATLAB Graph Partitioning Code**

Dear NA-neters,

I would like to know if there is available somewhere a public domain

graph partitioner code in Matlab? I just need this to recursively

partition (with separators) small graphs with a few thousand vertices

leading to a domain decomposition ordering of the nodes. This is going

to be used in a multilevel preconditioner for CG.

Many thanks

**Subject: Berkeley Lab AMR Available for Distribution**

The U.S. Department of Energy's Lawrence Berkeley National Laboratory

has released "Berkeley Lab AMR," a comprehensive library of adaptive

mesh refinement (AMR) software and documentation.

With the use of AMR and powerful parallel computers, new horizons are

opening in scientific research. Many everyday situations, such as

running an internal combustion engine or predicting weather, actually

involve very complex physical processes that scientists are only now

beginning to understand. At Berkeley Lab, scientists and mathematicians

are developing specialized tools and algorithms for computer modeling of

problems like these.

The tools are general enough that most computational problems involving

partial differential equations can potentially benefit from their use.

Now, these tools, including visualization software, and extensive

documentation supporting their application, have been produced as a CD

for general distribution. The CD contains an AMR overview, research

highlights and software.

Researchers interested in obtaining a copy of the Berkeley Lab AMR CD

can send requests to AMR@lbl.gov. For more information about Berkeley

Lab AMR, go to http://seesar.lbl.gov/AMR/ . To learn more about NERSC,

**Subject: Bound on the pth Largest Component of a Matrix-vector Product**

I am interested in computing an upper bound on the p th largest

component (for some p < n/2, though much smaller p is generally more

useful) of the product of a matrix with a vector. That is, I want to

compute an upper bound on the p th largest component of v = Aw, without

having to compute v. (It is, indeed, the p th largest component, rather

than the p th largest magnitude, in which I am intersted.) 'A' is a very

thin matrix: It has n rows and m columns with n >> m. Furthermore, I am

given a fixed A and several w's. So I do not mind spending a lot of time

analyzing A initially. But given a w, I need to compute a good bound fast.

(i) Does anyone know about good bounds for this problem.

(ii) I derived a few different bounds, with the following being the most

effective in my experiments for the application of interest to me:

Let $L \in \R^{N \times M}$, $L_{lp}^j$ the sum of the $p$ largest

components of column $j$ of that matrix, $L_{sp}^j$ the sum of the

$N-p$ smallest components of column $j$, $L_{ln}^j$ the sum of the

$p$ smallest components of column $j$, and $L_{sn}^j$ the sum of the

$N-p$ largest components of column $j$. Let $w \in \R^N$, $S =

\sum_{i=1}^N (Lw)_i$. Then an upper bound on the \pth\ largest

component of $Lw$ is given by

$$V_R \leq \frac{1}{2p}\left[S + \sum_{i=1}^N

\tilde{w}_i(L_{lp}^i-L_{sp}^i) -

\sum_{i=1}^N \hat{w}_i(L_{ln}^i-L_{sn}^i)\right]$$

where $\tilde{w}$ is given by

$$

\tilde{w}_i = w_i, w_i \geq 0; \ \tilde{w}_i = 0, \ {\rm

otherwise}

$$

and $\hat{w}$ by $\hat{w} = \tilde{w} - w$

It was effective when applied to the SVD of the matrix, instead of to

the matrix directly, and took m^2 time, which is a lot better then Nm

required for the computation of v and then finding the p th largest

value.

Has anyone seen similar bounds in literature, and do you know of any

literature that deals specifically with "thin" matrices? Thanks.

**Subject: Report on Workshop on Inner-Outer Iterations and Embedded Software**

Inner-outer iterations and embedded software

A Workshop at CERFACS

On September 11--12, 2000, CERFACS (Toulouse, France) hosted two

Industrial Days on Inner-Outer Iterations, a workshop focusing on

numerical quality and software coupling. This workshop was organized

at the request of three out of the four industrial shareholders of

CERFACS, namely AEDS (the new European consortium for Defence and

Aerospace), CNES (the French NASA) and EDF (French Electricity).

More and more often in their simulations, these industries are

making heavy use of either embedded iterative processes (at two or

more levels) or coupled software that exchanges information

successively between the subunits. Preliminary discussions lead to

the acknowledgement that the state-of-the-art in the understanding

of the numerical behaviour of embedded or coupled processes was not

advanced enough to fulfill the needs of the many users.

A workshop was therefore planned to bring together engineers and

researchers to allow the first to better specify their needs and the

latter to present up-to-date tools and existing research results on

the topic. This resulted in a two-day workshop supported by SMAI and

organised as follows. The first morning of the workshop consisted of

two tutorials. After the welcome address given by Iain Duff (CERFACS

and RAL), the first speaker, Sven Hammarling from Nag Ltd, gave a

lively and clear introduction to error analysis, particularly

concentrating on backward error analysis, and discussed its

implementation in modern software such as LAPACK. Then Andreas

Griewank from the Technical University in Dresden presented the

basics of automatic differentiation, a powerful tool to perform

forward error analysis and a sensitivity analysis on complex codes.

He also described its use for embedded processes arising in optimal

design. In the afternoon, industrial users were invited to report on

their experience in using embedded processes. Jean-Louis Vaudescal,

from EDF, described various applications in mechanics and neutronics

particularly focusing on a generalised eigenvalue problem arising in

the modelling of a nuclear core. Such a problem is solved by

successive iterations with Chebyshev acceleration but each step

requires the solution of a linear system which has to be computed

with an iterative solver due to the characteristics of the problem.

Jean-Louis Vaudescal insisted on the extreme sensitivity of the

convergence of the outer process with respect to the accuracy of the

inner one. Philippe Homsi from EADS concluded the first day by a

brief description of the major issues encountered in software

coupling for multidisciplinary physics such as the coupling of

acoustics and structure for aircraft design.

The second day of the workshop gave the opportunity for expert

researchers to present the state-of-the-art in the control of

embedded iterative processes. Even when there are only two levels of

iterations corresponding to solving a linear problem, many questions

concerning the optimal tuning of the inner process remain open. A

pioneer in the field of the control of inner-outer iterations and

inexact methods for Linear Algebra, Gene Golub from Stanford

University opened this session with an overview of his many

contributions with his young colleagues to the topic including

inexact variants of the Chebyshev method, an inexact Uzawa method,

inexact conjugate gradient methods or the Lanczos process with

inner-outer iterations. When the outer process is the Chebyshev

method, Golub has shown that it is possible in some cases to define

an optimal strategy for monitoring the inner process while

minimising the global cost.

Whereas it is known that an outer Newton-like method requires

increasingly inner accuracy as convergence proceeds, the picture is

completely different when the outer scheme is a Krylov-type method.

In her talk, Francoise Chaitin-Chatelin from CERFACS and University

Toulouse~I focused on this fundamental difference and illustrated it

by recent numerical experiments carried out by her group at CERFACS.

These experiments show that Krylov-type methods need an accurate

inner process only at the beginning of the convergence. This led

Amina Bouras and Val'erie Frayss'e (CERFACS) to propose and study a

relaxation strategy for Krylov-type methods which allows the inner

accuracy to deteriorate as convergence proceeds. This counter-

intuitive strategy can be shown to provide a substantial reduction

of the overall computer time required to obtain the solution with a

prescribed backward error.

Many important industrial domains can be successfully tackled by

this approach. As an example, Val'erie Frayss'e presented promising

results on domain decomposition methods for heterogeneous and

anisotropic problems, obtained jointly with Amina Bouras and Luc

Giraud at CERFACS. Returning to inexact Newton methods, the last

speaker Andreas Frommer from the University of Wuppertal discussed

their implementation and performance on parallel computers.

The workshop was ended by a lively round-table. Everyone

acknowledged that the industrial needs presented during the workshop

were particularly challenging and the engineers were strongly urged

to provide the community with detailed examples and data. The

workshop gathered 6 engineers and 24 researchers from 5 countries

(although this would increase to 13 if the multi-ethnic distribution

of CERFACS researchers is included). Its moderate size and the nice

and informal atmosphere really favoured fruitful discussions and

indeed fostered the birth of new collaborations. Abstracts, slides

and pictures are available from the URL:
