Subject: New Arbitrary Precision Arithmetic Software Package

New Arbitrary Precision Arithmetic Software Package

We are pleased to announce "arprec", a new software package for arbitrary
precision arithmetic calculations. Some features include:

- Written in C++ for performance and broad portability.
- Includes C++ and F-90 translation modules that permit one to utilize the
package with only minor changes to an existing C++ or F-90 program.
- Supports integer, floating and complex datatypes.
- Permits datatypes of different precision levels to be defined.
- Inter-operates with conventional integer and floating-point datatypes.
- Includes common transcendental function routines (sqrt, exp, sin, etc).
- Includes quadrature routines (i.e. numerical integration).
- Includes PSLQ integer relation routines.
- Includes special routines for extra-high precision (>1000 digits).

This software, as well as some related double-double and quad-double
precision software packages, are available from the URL:

Subject: OPT++, a Package for Nonlinear Optimization

OPT++ 2.0 Available for Download

The newest version of OPT++ 2.0, an object-oriented package for
nonlinear optimization is now available. There have been significant
improvements and new capabilities added since the last release. The new
version includes support for general linear and nonlinear constraints, a
new parallel optimization method, and a new nonlinear interior point
method. Other capabilities include parallel direct search, nonlinear
conjugate gradient, quasi-Newton and full Newton methods. OPT++ has
been ported to various platforms including IX86 Linux, Sun, SGI, and
DEC. A complete set of documentation has also been added with
descriptions of the major classes and extensive sample problems.

Subject: Postdoctoral Position at Institut Francais du Petrole

Postdoctoral position in scientific computing at the
Institut Francais du Petrole

Numerical simulation of multiphase production networks

The simulation of transient multiphase flow in pipes requires considerable
computational efforts. Today's IFP code is able to simulate compositional
three-phase flow in a 1D linear pipeline including equipments such as
valves, pumps,etc. However, oil and gas production devices are often
composed of several pipelines linked together into a complex network.
The goal of the postdoctoral position is to propose and to develop numerical
methods able to model junctions of pipelines.

The mathematical model is a PDE system composed of the mass conservation
equations of the components, together with the momentum and energy equation
for the mixture. The numerical scheme is based on a finite volume
discretization in space and a semi-implicit time discretization. The
programming will rely on a new software environment, which uses
object-oriented approach.

Student background
PhD in applied mathematics or scientific computing.
A knowledge in finite volume methods and hyperbolic systems of conservation
laws is necessary.

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

Contact Isabelle Faille at for more information.

research goals. The purpose of the fellowship is to stimulate
cross-fertilization of ideas and to apply computational science to
challenging problems in Science and Engineering. The fellows are
responsible for conducting their own research projects and are
encouraged to contribute to the CoLab environment of openness,
interaction and collaboration.

An applicant must have a Ph.D. or Sc.D. degree granted within three
years preceding the application date. We strongly encourage
applications from women and minorities.

Criteria used in the selection of postdoctoral fellows are the
applicants' scientific competence, their spirit of innovation and the
capability of conducting original and independent research in a highly
collaborative environment.

Successful applicants currently receive a stipend of about 90,000 to
100,000 SFR in the first year. These stipends are adjusted annually,
based on the governing guidelines of ETH Zurich.

We anticipate 5 to 10 initial appointments, followed by another 10
appointments within the next 6 months. The fellowships have a one to
three year term. Review of applications will begin July 1, 2002, and
will continue until the positions are filled.

Each applicant for a postdoctoral fellowship at the CoLab should

* An up-to-date curriculum vitae including summary of scientific work
experience, including :
o a detailed list of publications
o The names and addresses of three people familiar with the
applicant's research
o An abstract of her/his doctoral thesis

* A concise statement (1 to 3 pages) describing the applicant's
interest in CSE and the research that he/she wishes to pursue
during the CoLab appointment

We encourage applications via e-mail in electronic format (PDF, Word).
Inquiries and applications should be addressed to:
