Thanks to Ernst Hairer and all the people of Geneva

About two months ago, the conference ``Scientific Computation'' took place

in Geneva to celebrate Gerhard Wanner's 60th birthday. I will

not describe the talks; the abstracts may be found at the internet address

http://www.unige.ch/math/folks/hairer/conference/

(Several other people attended and paid tribute to Gerhard without giving

a talk, see the list of participants on the above page.)

What I would like to stress here is the perfect way Ernst and all the people

of the "Institut de Mathematiques de l'Universite de Geneve" have managed the

conference, AND THIS WITHOUT CHARGING ANY FEE.

There were a book of abstracts with list of participants, coffee breaks,

a boat trip, an excursion (a fantastic day in Chamonix) and a conference

dinner, The attendees of East-european and Asian countries were reimbursed.

How was this possible? First, there were sponsors, whose list may be

found under the above www-page (all of them academic, no Geneva bank...).

Second, there was an enormous work by Ernst, the organisers' spouses and the

employees of the Institute, who run the coffee breaks, the drinks and

the dessert of the dinner in the countryside of Geneva.

They deserve the warmest thanks of all the attendees !

Sure, one cannot expect such an engagement from all conference organisers.

But there is plenty of margin between no fee or a symbolic fee and the

several hundred euros we must pay to attend (too) many meetings.

Thank you all in Geneva, also for demonstrating that a perfect conference

can be organized without cashing such astronomical fees !

(It should be noted that another conference held in Switzerland this year,

"Latsis 2002, Iterative Solvers for Large Linear Systems", which celebrated

in Zurich 50 years of the conjugate gradient method, had a registration fee of

just 40 swiss francs (about 25 euros = 25 dollars), --- for more info,

see www.cg50.ethz.ch or the sites mentioned in SIAM News, June 2002.)

**Subject: New Book, Scientific Computing with Ordinary Differential Equations**

Springer-Verlag NY is pleased to announce the publication of Scientific

Computing with Ordinary Differential Equations from Peter Deuflhard of

the Konrad-Zuse-Zentrum Berlin and Folkmar Bornemann of the Munich

University of Technology (TUM) in our Texts in Applied Mathematics Series.

This text provides an introduction to the numerical solution of initial

and boundary value problems in ordinary differential equations on a firm

theoretical basis. The book strictly presents numerical analysis as part

of the more general field of scientific computing. Important algorithmic

concepts are explained down to questions of software implementation. For

initial value problems a dynamical systems approach is used to develop

Runge-Kutta, extrapolation, and multistep methods. For boundary value

problems including optimal control problems both multiple shooting and

collocation methods are worked out in detail. Graduate students and

researchers in mathematics, computer science, and engineering will find

this book useful. Chapter summaries, detailed illustrations, and

exercises are contained throughout the book with many interesting

applications taken from a rich variety of areas.

New Book, Finite Volume Methods for Hyperbolic Problems

I am pleased to announce that the following book is now available:

Finite Volume Methods for Hyperbolic Problems

by Randall J. LeVeque (University of Washington),

Cambridge University Press, 2002. xix, 558 pp., 135 figures, 108 exercises

Hardback: ISBN 0-521-81087-6, $120 retail

Paperback: ISBN 0-521-00924-3, $45 retail

This book is based on my ETH Notes "Numerical Methods for Conservation Laws"

published by Birkhauser in 1990, but has been completely reorganized and

greatly expanded. All of the sample computations in the book were computed

using CLAWPACK, and the webpage

http://www.amath.washington.edu/~claw/book.html

contains pointers to numerous animations that supplement figures in the book,

and to all the source code used to perform the computations.

For more details, including the table of contents and first chapter,

**Subject: CLAWPACK, Software for Conservation Laws**

CLAWPACK Version 4.1 is now available

A new version of the CLAWPACK software has recently been installed at

http://www.amath.washington.edu/~claw

This free "conservation laws package" includes fortran routines to

solve hyperbolic systems of partial differential equations (not just

conservation laws) in 1, 2, and 3 space dimensions. Version 4.1

differs from the previous Version 4.0 most significantly in the

3-dimensional routines, where some calling sequences have been changed.

The User's Guide has also been extensively rewritten and expanded; see

http://www.amath.washington.edu/~claw/doc.html

An adaptive mesh refinement version has been added in 3D,

extending AMRCLAW from 2D to 3D. This portion of CLAWPACK is

based on codes originally developed by Marsha Berger.

CLAWPACK also contains MPI versions, matlab routines for graphics and

visualization, and a number of sample application directories that serve as

templates for applying the software to other problems. Examples include

advection, acoustics equations (in homogeneous and heterogeneous media),

gas dynamics, elasticity, shallow water equations, and traffic flow.

**Subject: NUFFT, Non-uniform FFT MATLAB Toolbox**

Dear colleagues,

Daniel Potts recently announced his C library for nonuniform FFT which

is located here: http://www.math.uni-luebeck.de/potts/nfft

For those who would prefer to experiment with such tools in Matlab,

we have independently developed a NUFFT toolbox that uses interpolators

that have been min-max optimized to minimize the worst-case interpolation

error. The toolbox is one part of a large collection of m-files developed

for image reconstruction problems, and is located here:

Attention: Ms. Carrie Eder

The ASCI/Alliances Center for Astrophysical Thermonuclear Flashes at the

University of Chicago invites applications for a research position

in computational physics. The center's purpose is to develop and apply

a general-purpose multi-physics adaptive mesh refinement code, FLASH.

The primary applications of the FLASH code are simulations of astrophysical

thermonuclear explosions.

The successful applicant will develop physics models needed for these

simulations, design and implement appropriate numerical algorithms and

validate the models against experimental results. Experience in

computational physics and parallel computing are required. Interest

in astrophysical applications, implicit solution techniques, and

fluid dynamics or radiation transport are highly desired.

The position is for a period of two years with the possibility of renewal.

To apply, please submit to the above address a curriculum vitae, a list

of publications, a brief description of research interests and the names

and contact information for three references. Applications received

**Subject: Postdoctoral Position at Institut Francais du Petrole**

Domain decomposition methods for multiphase flow in porous media

Domain decomposition methods are used for complex models of

multiphase flow in porous media (sedimentary basin cut by faults

along which displacements can occur, petroleum reservoir with a fine

description of the well bore). The computational domain is then

decomposed into subdomains in which the partial differential

equations are solved locally, continuity between subdomains being

imposed iteratively.

The set of partial differential equations considered is a mixed

hyperbolic - parabolic system and is discretized by a fully implicit

time scheme. The objective of the post-doctoral work is to improve

interface conditions for the domain decomposition method implemented

at IFP for the system of partial differential equations:

study from a theoretical point of view the existing interface conditions

propose and implement new interface conditions between subdomains

in order to achieve higher convergence rates.

The successful candidate will be located at IFP in Rueil Malmaison,

a pleasant suburb 10 miles from Paris Notre Dame. The activity of the

Institut Francais du Petrole is threefold : research and development,

education and training, and information. It is designed to serve the

oil, gas and automotive industries. It is unique in Europe and covers

all the sectors from exploration and production, refining and

petrochemicals, to the end use of petroleum products in the internal

combustion engine.

The salary will be of 2200 euros/month. The duration is 12-18 months.

This is a joint work between IFP and the Centre de Mathematiques

Appliquees de l'Ecole

Polytechnique located in Palaiseau.
