**Subject: SIAM Annual Meeting at Stanford, July 1997**

The annual meeting of SIAM will take place at Stanford the week of July

13-18, 1997. Some of the speakers who have accepted are Margaret

Cheney, Alexandre Chorin, Eric Grosse, John Hennessy, Don Knuth, Velvel

Kahan, and Tinsley Oden (for a list of the organizers and updated

informaton see http://www.siam.org/meetings/an97/an97home.htm). Since

Stanford is at the foutainhead of Silicon Valley, there will be a

number of speakers and minisymposia associated with compter science as

connected with scientific computing.

Speaking on behalf of the organizing committee, we are also interested

in emphazing developments of applied mathematics in the Pacific rim.

We invite our colleagues to organize mini-symposia which will bring to

us the latest developments in your country in applied mathematics and

scientific computing.

Stanford is currently in the midst of a major re-building. The

Computer Science Department is now housed in the Gates Building, and

new buildings are being constructed for our Statistics and Electrical

Engineering Departments. If you have not visited in the last five

years, you'll be amazed by all the changes.

We hope to see you at SIAM97. We believe it will be a meeting to

remember!

NEW BOOK ANNOUNCEMENT:

NUMERICAL MODELLING OF RANDOM PROCESSES AND FIELDS:

ALGORITHMS AND APPLICATIONS

by V.A.Ogorodnikov and S.M.Prigarin

Publisher: VSP, Utrecht, The Netherlands, 1996

/240 pages, 22 figures and 23 tables/ ISBN 90-6764-199-5

The book deals with the development and investigation of

numerical methods for simulation of random processes and

fields. The first two chapters describe scalar and

vector-valued Gaussian models. Conventional autoregressive and

moving-average schemes and their vector modifications are

indicated. Great attention is given to the spectral models. In

addition, several special methods are presented. The third

chapter is dealt with non-Gaussian models. The method of

nonlinear transformation of Gaussian functions is studied in

some detail as well as models of random fields related to

stationary point flows, models based on nonlinear stochastic

differential equations, etc. The issues of compatibility of

marginal distributions and covariances of random processes are

considered here, too. The fourth chapter of the monograph is

dealt with issues of convergence of approximate models of

random fields. The last two chapters deal with stochastic

modelling applications. New application areas such as

simulation of meteorological processes and fields, sea surface

undulation and stochastic structure of clouds are presented

here.

Moreover, the book includes three appendixes, in which the

algorithms for modelling of random numbers, some data from the

random processes theory and the connections between discrete

and continuous stochastic models are discussed in brief.

The book is intended for experts of statistical modelling as

well as specialists of application problems of Monte Carlo

methods.

I have written a monograph titled "THE ADI MODEL PROBLEM" which includes most of

my published work on this subject along with new analysis and results. Much of

the more recent matereial relates to complex spectra and was motivated by

application of ADI iteration to solution of the Lyapunov and Sylvester matrix

equations. The Chapter headings are:

1. The Peaceman-Rachford model problem

2. The two-variable ADI problem

3. Model problems and preconditioning

4. Complex spectra

5. Numerics

**Subject: Block Preconditioning Toolkit Available**

BPKIT, Block Preconditioning Toolkit, Available

http://www.cs.umn.edu/~chow/bpkit.html

BPKIT is a toolkit of block preconditioners for the iterative solution of

linear systems. The most effective general purpose and black-box type of

preconditioners are available, including block SSOR, block tridiagonal ILU,

and the block extension of point ILU with level-of-fill. Any of these

``global'' preconditioners may be coupled with one of a large collection of

``local'' preconditioners for approximately or exactly inverting or solving

with the diagonal or pivot blocks. These include a number of new approximate

inverse techniques. By combining a global and local preconditioner, a wide

variety of preconditionings are possible, matched to the difficulty and

structure of the problem. For example, the following popular methods are

possible:

- Block SSOR, using level-of-fill or threshold-based ILU to solve with

the diagonal blocks

- A block version of level-based ILU using ``exact'' inverses for the

pivot blocks

- ILU on a block tridiagonal system, using an approximate inverse technique

suitable for the structure of the pivot blocks

- Matrices with no block structure may be treated as a single block,

and a single local preconditioner may be used.

The blocks may be stored in dense or sparse formats, and user-defined data

structures may also be used. Variable block sizes are allowed within a

matrix. Operations with the blocks call the BLAS, LAPACK, or the sparse

BLAS, for efficiency across many platforms. The selection of larger blocks

usually gives higher performance. BPKIT supports the preconditioning of a

block of vectors, to enhance efficiency when block iterative methods are

used. A flexible GMRES iterative method is provided in BPKIT for users

who do not have an iterative method readily available. A test program

will read any linear system in Harwell-Boeing format and solve it using

any combination of preconditioners and parameters specified by the user.

This is important in the ``experimentation'' stage when trying to solve

problems from new applications. BPKIT is callable from C/C++ and FORTRAN.

BPKIT is written in standard C++ and FORTRAN, and runs on several types of

workstations and Cray supercomputers. BPKIT is not parallel; for large

applications it is suitable for the local solvers per processor/node or

domain.

The most important feature of BPKIT is that it is user extensible, since

an entirely black-box approach to high-performance preconditioning is

currently not possible. Local and global preconditioners written in any

language may be added. A few simple lines of C++ must be written in order

to make the new ``objects'' polymorphic with the others (i.e., may be

treated like other local and global preconditioners). User-defined data

structures for the blocks and block matrices can also be added.

The source code to BPKIT is freely provided.

BPKIT is available at: http://www.cs.umn.edu/~chow/bpkit.html

**Subject: Information on Nonacademic Mathematics Careers**

The AMS-SIAM Mathematical Sciences Career Information Web site opened in

November at http://www.siam.org (then click on "career information"). Each month

the site profiles the careers of mathematicians working in nonacademic positions

in industry, business, or government in an effort to demonstrates the range of

career opportunities available to mathematicians. These featured mathematicians

then participate in an ongoing bulletin board in which they are available to

answer open forum questions from users pertaining to preparation for or

employment in the nonacademic sector.

The Web site also contains descriptions of industry applications and links to

sites with resource information for students entering the job market. The

professional profiles link to companies employing mathematicians, many of which

post information about job opportunities on their Web sites. There are also

links to on-line job listing services that advertise positions in the sciences

and engineering.

Beginning in November 1996, the Web site will allow graduate students in the

mathematical sciences interested in finding out more about nonacademic careers

to sign up to participate in a mentoring program that will match them with a

mathematician working in the nonacademic sector. Mentors can answer questions

about the work environment in industry and about the process of applying for

jobs outside academia.

If you would like to participate in this project as a mentor or be considered as

a featured mathematician, contact Linda C. Thiel, Project Director, at

thiel@siam.org.

Featured on the bulletin board in October are Mary Brewster, a senior research

scientist with Battelle Pacific Northwest National Laboratory who does

probabilistic modeling for waste tank safety analysis and develops numerical

wavelet methods for problems in computational chemistry; Stewart Gleason, a

consulting actuary with Ernst & Young who is building a model that will be used

to price medical malpractice business for doctor groups; Jeff Kidder, a senior

software engineer with Intel Corporation who is leading a project that is

implementing and optimizing speech compression algorithms for use in a video

conferencing system; and Craig Benham, acting chair of the Department of

Biomathematical Sciences at Mount Sinai School of Medicine who works on

problems related to DNA structure.

**Subject: Research Studentship at RMCS Shrivenham**

ROYAL MILITARY COLLEGE OF SCIENCE

CRANFIELD UNIVERSITY

DEPARTMENT OF APPLIED MATHEMATICS AND OPERATIONAL RESEARCH

Research studentship in numerical mathematics/scientific computing

Applications are invited for the above studentship, which is for fees

and a maintenance bursary of approximately seven thousand pounds

per annum.

The Applied Mathematics and Operational Research Group is part of

the Royal Military College of Science (RMCS) situated at Shrivenham

in the Vale of the White Horse district of Oxfordshire.

The College is a faculty of Cranfield University and the research

student will be registered for a Cranfield degree.

Techniques of particular interest to the group are the numerical

solution of integral equations, including boundary element methods;

finite element and finite difference methods and approximation and

data fitting including neural networks.

Work on boundary elements has been continuing since 1980 with the

focus on numerical techniques, applications in fracture mechanics,

free surface problems in fluid mechanics and electrodeposition.

It is envisaged that the student will embark on research in the

application of modern computing techniques to the development of

more efficient boundary element methods. The research may

encompass numerical integration techniques, parallel processing

and adaptive meshing and will require extensive programming in

Fortran 90.

Although previous experience of boundary element methods is not required,

a strong mathematics/numerical analysis background with a good grounding

in computer programming is essential. Applicants should have

(or expect to obtain this summer) at least an upper second class

honours degree or an equivalent postgraduate qualification.
