Subject: Special Issue of Theoretical Informatics on Real Numbers

Special issue of the journal
Theoretical Informatics and Applications

Guest editors: Vasco Brattka, Christiane Frougny, Norbert Mueller

Efficient manipulation of real numbers in computers is still a
challenge. Many interesting theoretical and algorithmic problems are
linked with that topic and belong to quite distant fields such as
computer science, number theory, numerical analysis, computer algebra
and logics. Several special issues on real numbers and
computers have been previously published in the journal Theoretical
Computer Science, as follow-up to the RNC meetings on these topics.

The last meeting was RNC6 which took place in Dagstuhl, Germany,
in November 2004, see
However, this call for papers is open to authors who did not attend RNC6.

Scientists working on questions related to real computer arithmetic
are encouraged to present the theoretical or algorithmic aspects of
their results, even if they did not attend the RNC6 conference. Survey
and tutorial articles may be suitable if clearly identified as
such. Topics include (but are not restricted to) the following list:

* Foundation and properties of number systems
* Computability and complexity
* Formal aspects and automatic proof checking
* Links with number theory and automata theory
* Basic arithmetic operations
* Implementation of the standard and special functions
* Engineering of floating and fixed point algorithms
* Symbolic manipulation of numbers
* Accuracy and reliability for applications and industry
* Robust geometric algorithms and exact geometric computation
* Hardware design support and implementations

Subject: Winter School in Leipzig on Hierarchical Matrices

Second Announcement Winter School "Hierarchical Matrices"

Organizers: Wolfgang Hackbusch, Lars Grasedyck, Steffen Boerm
(Max Planck Institute for Mathematics in the Sciences,

Time: February 7th to February 11th, 2005

Registration Deadline: December 6th, 2004

Topic: Hierarchical Matrices can be a useful tool for the treatment of
integral operators as well as the solution of linear systems arising
in the discretisation of elliptic partial differential equations.
Moreover, the representation of matrices in the hierarchical matrix
format is suitable for the efficient solution of matrix equations.

The aim of this winterschool is to teach the necessary theoretical
foundations for hierarchical matrices, but most of all the efficient
implementation of the algorithms. The practical realisation on the
computer will be done during the exercise courses in the afternoons.
The participants will use the HLib library in order to assemble and
solve BEM and FEM systems. Lecture notes are available in electronic

Guelph, ON, CANADA

Hosted by SHARCNET
Shared Hierarchical Academic Research Computing Network

HPCS is a multi-disciplinary meeting to discuss new and exciting
scientific and technical work involving High Performance Computing.
Researchers from all disciplines in the sciences, engineering,
mathematics and applied human sciences are invited to participate. All
papers will be refereed. Both oral presentations and posters sessions
will be available.

To submit papers or for more information, please email

The 3rd annual OSCAR (Open Source Cluster Application Resources)
Symposium will be held in conjunction with HPCS 2005.

The 3rd Annual Symposium on Open Source Cluster Application Resources

With over 130,000 downloads since its first public release in April
2001, OSCAR's popularity speaks to its effectiveness in providing
cluster installation, management, and computing software stack. OSCAR is
a snapshot of best-known methods for building, programming and using
clusters. OSCAR started as a traditional Beowulf software stack, has
expanded in recent years to embrace numerous cluster computing styles
including diskless, high-availability, scalable systems, and single
system image. The project is an open effort among industry, academic and
research groups to help simplify the setup and management of computing
clusters. Further information is
available at the OSCAR web site,

Subject: Research Positions at Simula Research Laboratory, Oslo, Norway

Open Positions in Computational Geology
Simula Research Laboratory, Oslo, Norway

Simula Research Laboratory plans to build a strong research group in
Computational Geology. This group will address geological processes
that are important to the oil and gas industry, such as structural
reconstruction of basins, depositional history, rock mechanics, and
porous media flow.

We are currently looking for highly skilled personnel for positions at
Ph.D. and Postdoc levels in this group. Your qualifications must

* M.Sc. or Ph.D. degrees in geoscience, with special emphasis
on petroleum-related branches

* Good understanding of mathematical models for geological
and geophysical processes

* Experience with development of computer codes for simulation
of geological or geophysical processes

The new research group will have close collaboration with industrial
partners in the oil and gas sector. In this team, one of your special
responsibilities will be to act as a scientific liason between pure
geoscientists and specialists on numerical methods and software.

With a reservation concerning the final level of funding, we now
accept applications for the open positions. Please send your CV and
publication list by email to Are Magnus Bruaset (

Simula Research Laboratory was established in 2001, and conducts basic
research in selected areas within information and communication
technology. The Computational Geology group will be part of the
Department of Scientific Computing, which is an internationally
recognized research unit within its target fields. The department has
a particular focus on simulation of cardiac processes, and on
middleware tools for large-scale simulations based on partial
differential equations. The laboratory is located in modern office
facilities at Lysaker, just outside the city of Oslo, Norway. See for further information about the laboratory.
