**Subject: Request for Math-Related URLs**

SIAM is currently reorganizing and expanding our "World of Mathematics and

Computing" web pages. Our goal is to provide a comprehensive list of

mathematics-related Web servers, FAQs, bibliographies, software repositories,

newsgroups, etc. To that end, we are requesting URLs from those in the

mathematics and computing community.

The World of Mathematics and Computing page, still very much under construction,

is available at http://www.siam.org/world/ . (It is not currently available

from SIAM's home page.) The optimization link is the best developed of those

subjects currently linked and can be used as an example of the type of

information we are hoping to provide for our users.

Please note that we will not be relying only on the information provided via

this request. We will continue to build this area using the various search

engines available on the Web.

If you have a URL that you would like to submit, please send it to

helfrich@siam.org. Please include several key words to assist us in properly

categorizing the site. You are not limited to the key words listed on the

World of Mathematics and Computing main page. We expect to add other topics

as this site grows.

A N N O U N C I N G

HotGAMS

A Java(tm) powered frontend to the

NIST Guide to Available Mathematical Software

http://math.nist.gov/HotGAMS/

HotGAMS, a Java powered client of the NIST Guide to Available

Mathematical Software (GAMS) server, is now available for public use

on the Internet on an experimental basis.

The Guide to Available Mathematical Software is an on-line

cross-index of mathematical and statistical software in use at the

National Institute of Standards and Technology (NIST). Nearly 10,000

problem-solving modules from some 100 software packages are indexed,

including a large subset of the netlib collection. The primary

indexing mechanism is a tree-structured taxonomy of mathematical and

statistical problems. The system is also a virtual repository,

providing redistribution of abstracts, documentation, and source of

much of the software that it catalogs.

HotGAMS allows interactive exploration of the problem taxonomy,

various search operations, and enhanced filtering or `refinement' of

search results compared to its predecessors. A current research

interest is in how to reduce a large number of apparently appropriate

software modules to a few truly relevant ones. HotGAMS begins to

address this need and will serve as a testbed for future

improvements.

This book comtains the course notes of the Summerschool on High Performance

Computing in Fluid Dynamics, held at the Delft University of Technology,

June 24-28, 1996, under the auspices of ERCOFTAC (European Resarch Community

on Flow, Turbulence and Combustion) and the J.M. Burgers Center (Graduate

School for Fluid Dynamics, The Netherlands).

The book is addressed to graduate students and researchers in industry engaged

in scientific computing, who have little or no experience with high

performance computing, but who want to learn more, and/or want to port their

code to parallel platforms. Applications in computational fluid dynamics are

emphasized.

The lectures presented deal to a large extent with algorithmic, programming

and implementation issues, as well as experiences gained so far on parallel

platforms. Attention is also given to mathematical aspects, notably domain

decomposition and scalable algorithms. Computer science basics are not

emphasized. Topics considered are: basic concepts of parallel computers,

parallelization strategies, programming aspects, parallel algorithms,

applications in computational fluid dynamics, the present hardware situation

and developments to be expected. There are ample references to the current

literature, so that the work is a good starting point for those who want to

enter the field of high performance computing, especially if applications

in fluid dynamics are envisaged.

**Subject: Positions at Lawrence Berkeley National Laboratory**

POST-DOC POSITIONS AVAILABLE

Center for Computational Sciences and Engineering (CCSE)

Lawrence Berkeley National Laboratory

Berkeley, California

The Center for Computational Sciences and Engineering has a

number of positions available for post-doctoral researchers or

visiting scientists. These are full-time, one-year-term appointments

with the possibility of renewal.

The mission of CCSE is to develop and apply advanced computational

methodologies to solve large-scale scientific and engineering

problems. The methodology used by CCSE centers around the

development and use of adaptive high-resolution finite-difference

methods for fluid dynamics and composite grid or embedded

boundary representations of engineering geometries. Application

areas include atmospheric flows, low speed reacting flows, and

compressible flows. The successful candidate will participate in

an on-going research effort in one of the above areas.

There are also positions available for developing software

infrastructure to support our numerical methodology. These include

an opening for someone experienced in numerical linear algebra,

particularly iterative solvers, to extend existing adaptive grid

multigrid libraries, and someone to implement parallel versions

of our methodology for the Cray T3E at NERSC.

All positions require significant programming and technical

interaction with other members of CCSE. The successful applicant

must be able to work with and extend existing software and

develop reliable and readable code. Throughout the project, the

appointee should be able to investigate issues of algorithmic

design as well as validate the resulting software by comparison

with available data. She or he will also be expected to prepare

results for publication in scientific journals and for presentations

tions at national meetings.

Requirements for these positions are:

* working knowledge of C++ and FORTRAN,

* Ph.D. within the last four years in applied mathematics,

engineering, computer science, or related field (for post-doc

positions only)

Familiarity with modeling low Mach number flows a plus. Experience

in parallel computing a plus.

If interested, please contact John Bell at jbbell@lbl.gov.

PROGRAMMER POSITIONS AVAILABLE

Center for Computational Sciences and Engineering (CCSE)

Lawrence Berkeley National Laboratory

Berkeley, California

The Center for Computational Sciences and Engineering has a

number of positions available for scientific programmers. These

are full-time, career appointments.

The mission of CCSE is to develop and apply advanced computational

methodologies to solve large-scale scientific and engineering

problems. The methodology used by CCSE centers around the

development and use of adaptive high-resolution finite-difference

methods for fluid dynamics and composite grid or embedded boundary

representations of engineering geometries.

We are seeking candidates to participate in the following projects:

* development of an interface between CAD/CAM descriptions of

engineering geometries and CCSE's fluid dynamic simulation

programs.

* development of interfaces between CCSE's fluid dynamics codes

and complex physics packages such as chemical databases for reaction

rates and thermodynamic properties for modeling reacting

flows

* development of data structures and C++ class libraries to

support the implementation of CCSE's adaptive methodology

* development of a parallel processing software layer for C++

libraries that supports adaptive computations in fluid dynamics.

The successful applicant in each case will be part of a team engaged

in implementing and releasing high-performance fluid dynamic simulators

and visualization software. These positions require programming

and technical interaction with other members of CCSE and vendors.

Requirements for these positions are:

* Experience with object-oriented programming and C++

* B.A., B.S., or M.S. in computer science, mathematics or

engineering, or equivalent experience.

Background in scientific programming and algorithm implementation

would be a plus. Experience on Cray supercomputers and high-

performance DEC alpha workstations is a plus.

**Subject: Postdoctoral Position at University of Durham, England**

A postdoctoral research position is available for a three-year, EPSRC

funded, collaborative project in the Department of Mathematical

Sciences, University of Durham, England, entitled:

"Bayes Linear Forecasting and Decision-Making for Large-Scale Physical

Systems in the Petroleum Industry"

The objectives of this three-year research project, funded by the UK's

Engineering and Physical Sciences Research Council, are (i) to develop

a Bayes linear approach to forecasting and decision making using

complex, high dimensional models for physical phenomena such as

hydrocarbon reservoirs; (ii) to devise useful prior descriptions for

the input and output uncertainties in such models, synthesising

graphical elicitation tools for expert beliefs, theoretical analysis

and the study of simplified forms for the models; and (iii) to combine

(i) and (ii) to derive improved methods for asset management for

hydrocarbon reservoirs and for decision problems such as leak

detection for pipeline networks, and test these methods in a series of

case studies. The project is in collaboration with Scientific

Software-Intercomp (UK) Ltd, a leading software developer for the oil

industry.

This project follows on from a recent EPSRC funded project held by the

investigators which concerned strategies for matching hydrocarbon

reservoir simulator output to actual reservoir production history.

The project involves a combination of statistical, numerical and

computational skills and an ability to develop innovative solutions to

challenging practical problems. Desirable qualities include experience

of Bayesian methodology, modelling of complex stochastic systems and

fluent computing skills. The appointee will be expected to

collaborate closely with the investigators in all areas.

The position is for three years from 1st October 1996, or later by

negotiation, and initial salary will be up to 15986 UK pounds on the

RA(1A) scale. We welcome informal enquiries, which should be addressed

either to Professor Michael Goldstein (e-mail:

michael.goldstein@durham.ac.uk, tel.: +44-191-374-2365) or to Dr Allan

Seheult (e-mail: a.h.seheult@durham.ac.uk, tel.:

+44-191-374-2371). Application forms and further particulars are

available from the Director of Personnel, Old Shire Hall, Durham DH1

3HP, England (e-mail: acad.recruit@durham.ac.uk, fax:

+44-191-374-7253). Please quote reference A582. The closing date for

applications is 19th July 1996.

Mathematical Sciences and about Durham, see the WWW page (URL

http://fourier.dur.ac.uk:8000/stats/announce.html), which also has

information about the project and a paper outlining a case study for

this problem.
