**Subject: Comparing Krylov Linear Equation Solvers**

Dear Colleagues,

Appeal for Help

We are preparing a work for publication, a significant part of

which will be comparisons of various Krylov LE solvers. Although

we have compared the basic versions of most available algorithms on

various standard problems (taken from the Harwell-Boeing and other

well-known collections) we do not have the resources to make similar

comparisons of the look-ahead and preconditioned versions. We are

therefore requesting any group or individual who has written such a

program to help us.

Our current thinking is that we would ask for the algorithms

to be tested on a set of problems provided by us but we would welcome

in addition tests on a similar number of problems chosen by the

programs' authors. This would permit algorithms that are particularly

good in a certain area to be displayed to advantage. The results would

be presented graphically, probably on a CD-ROM.

We would want the most stringent standards to be applied, e.g.

a convergence criterion of 10e-14 for the ratio of the residual and

the right-hand side norm, and we would wish to plot the exact residual

norms, not those computed recursively by the algorithm. We would also

ask that the data be presented in a particular format (a .mat file)

ready for presentation to our graph-plotting routines.

Any questions, suggestion, requests for further information

or (of course) offers to participate should be sent to either

broyden@csr.unibo.it or vespucci@spm.it

Thank you for co-operation,

C. G. Broyden and Maria-Teresa Vespucci.

**Subject: Generalized Saddle-point Problem**

In many applied problems, it is necessary to solve a saddle point

problem of the form

[ A B; B' 0] [x;y] = [f;g]

where A and B are matrices of size n \times n. A and B are symmetric and

indefinite. I am looking for suitable iterative solution procedures.

**Subject: Matlab GUI for Pseudospectra**

The Matlab GUI for pseudospectra (as demonstrated at the Copper Mountain

2000 conference) is now availale for download.

The web address is:

http://web.comlab.ox.ac.uk/oucl/work/tom.wright/psgui/index.html

It has been designed to make computing psuedospectra simpler and more

interactive. Some of the features include:

* Speed: once the GUI has been initialised, all computation is O(N^2)

* Interactive zooming with the mouse

* `Smart' default contour levels, and the ability to change the levels

plotted without re-computation

* Easy control over axes and grid size

* Choice of colour or black and white

There are two main areas of use for the GUI:

* To compute the full pseudospectra of dense matrices of dimension up

to the order of a thousand (available now)

* To compute a portion of the pseudospectra of large sparse matrices

around the eigenvalues determined using eigs (to be available for

Matlab version 6)

**Subject: New Code for Stiff Delay Equations**

A new Fortran 90 code RADAR5 for the numerical solution of stiff

delay equations is available at

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

It is based on the 3-stage Radau IIA implicit Runge-Kutta method,

and is able to solve retarded differential-algebraic equations,

including neutral problems with vanishing or small delays.

Driver examples for seven problems are also available.

Comments and remarks are welcome.

http://www.springer.de/cgi-bin/search_book.pl?isbn=0-387-98959-5

The purpose of this book is to provide the mathematical foundations of

numerical methods, to analyze their basic theoretical properties

(stability, accuracy, computational complexity) and demonstrate

their performances on examples and counterexamples which outline their

pros and cons. This is done by using the MATLAB software environment

which is user-friendly and widely-adopted. Within any specific class of

problems, the most appropriate scientific computing algorithms are

reviewed, their theoretical analysis is carried out and the expected

results are verified on a MATLAB computer implementation. Every chapter is

supplied with examples, exercises and applications of the discussed theory

to the solution of real-life problems.

PhD Position at Institut Francais du Petrole, Paris

Domain decomposition methods for modelling hydrocarbon reservoir formation

Basin modelling aims at reconstructing the time evolution of a sedimentary

basin in order to make quantitative predictions of geological phenomena

leading to oil accumulations. It accounts for porous medium compaction,

hydrocarbon formation and migration.

Recent evolutions of basin simulators have contributed to improve the

treatment of geological discontinuities such as faults. These faults divide

the basin into blocks whose deformations cause geological layers to slide

between themselves. A natural discretization of these complex geometries

involves sliding meshes which do not match.

The main scientific issue is the design of efficient and accurate finite

volume discretizations and solvers for single and mutiple phase Darcy flow

in highly hetereogeneous media for nonmatching grids. The domain

decomposition approach will be used as it enables efficient handling of

non-matching grids.

The candidate will join the scientific computing group of the Applied

Mathematics Departement of IFP. He will work within the basin modelling

and reservoir simulation projects. This is a join project with the Applied

Mathematics department of the Ecole Polytechnique, Paris (cmapx). The PhD

director is Frederic Nataf from the cmapx. Applicants should posess some

background in numerical simulation of PDE's and linear algebra as well

as programming experience in C. The fellowships apply only to non french

european citizens (including eastern europe but excluding Ukraine, Russia,

Bielorussia).

To apply, send resume, statement of research, and a CV to

roland.masson@ifp.fr as well as the coordinates of two references.
