Subject: New Book on Stochastic Simulation



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

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

1. Statistical simulation of discrete Gaussian processes
and fields with a given correlation structure
2. Spectral models of Gaussian random fields
3. Numerical models of non-Gaussian processes and fields
4. Convergence of numerical models of random fields in
Monte Carlo method
5. Simulation of random fields in stochastic problems of the
atmosphere - ocean optics
6. Hydrometeorological applications of statistical simulation
A1. Synopsis of the theory of stochastic processes
A2. On correspondence between discrete and continuous
linear homogeneous stochastic models
A3. Coding of multiplicative generators of pseudorandom numbers

Subject: Monograph on the ADI Model Problem

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

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

- 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

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.

Subject: Information on Nonacademic Mathematics Careers

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

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



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.
