Subject: Survey of Freely Available Linear Algebra Software

Survey of Freely Available Linear Algebra Software

I'm updating a survey I did last year on freely available software
for the numerical solution of linear algebra problems.
Of interest is software for high-performance computers
that's available on the web in source form for solving problems
in numerical linear algebra, specifically dense, sparse direct and
iterative systems and sparse iterative eigenvalue problems.
The current list is at:
Please let me know about updates and corrections.
I'll post the updated list in a few weeks.

Subject: Conference in Spain on Problem Solving Environments

European Research Conference Series on
Advanced Environments and Tools for High Performance Computing

Problem-Solving Environments: Infrastructure and Prototypes
12-17 June 1999
San Feliu de Guixols, Spain

accessible through the conference web site

Conference Scope

Research into problem-solving environments (PSEs) is an active and expanding
field, with the potential for a wide impact on high performance computing.
PSEs provide software tools and expert assistance to the user, and serve as an
easy-to-use interface to high performance computing resources, thereby allowing
the rapid prototyping of ideas, detailed analysis, and higher productivity.
The conference gives a broad interpretation to what is meant by a PSE, but
in general a PSE provides a complete integrated computing environment for
composing, compiling, and running applications in a specific problem area.
A PSE may also incorporate many features of an expert system, and provides
extensive assistance to users in formulating problems, running the problem
on an appropriate computing platform, and viewing and analysing the results.
In addition, a PSE may have access to web-based information resources,
sophisticated job control systems, and visualisation environments. PSEs may
incorporate compute-intensive components, such as the solution of a complex
mathematical model, and/or data-intensive components employed, for example,
in Geographical Information Systems or database applications. Among the
research areas relevant to PSEs are distributed computing, computational
science and engineering, software technologies such as Java, CORBA, and XML,
mobile agents, immersive visualisation environments, computational steering,
knowledge discovery, the remote control of scientific instruments, and
concurrent and collaborative engineering.

Subject: Postdoctoral Position at Northeastern University

Post-Doctoral Research Position Available at Northeastern University,
Boston MA in Computational Physics and Signal Processing.

Description: As part of a contract from the US Department of Energy
aimed at the development of physics based signal and image processing
methods for environmental remediation, a post-doctoral research
position is available at Northeastern University in Boston, MA
combining elements of computational physics and signal/image
processing. In particular, we are interested in characterizing and
tracking the structure over time of contaminant plumes based on
cross-well, bore-hole radar data. The initial phase of the work will
be directed toward the refinement of an existing 3D vector
electromagnetic scattering code used to describe the propagation of
energy through the earth, the interaction of the energy with the
plumes, and the process of measuring the resulting scattered
fields. The second portion of the research will center on the
development of data inversion algorithms based on these models. We
are currently considering a variety of methods for approaching these
problems including 1. A traditional inverse scattering formulation in
which a full 3D reconstruction of the electrical properties of the
medium is produced. Essentially this approach requires the solution
of a high dimensional non-linear inverse problem. 2. Methods based on
array or match field processing techniques for which the processing
objective is the determination of the location of an object of
partially known shape and composition. 3. Active contour/active
surface techniques which are specifically tailored to the
determination of the shape of an unknown perturbation in the medium.
Implementation of these methods in a recursive, Kalman filtering-type
framework to perform plume tracking is also of interest.

Requirements: A Ph.D. and strong analytical skills in a field relevant
to the above described work (eg. Electrical Engineering, Mathematics,
Physics, etc.) with experience in at least a subset of the following

1. Signal or image processing with emphasis on restoration methods,
2. Computational electromagnetics,
3. Numerical analysis
4. Inverse scattering.

The candidate will be expected to carry out research in an independent
manner and if interested aid in the supervision of Master's and
Doctoral level graduate students. Strong oral and written English
skills are a must. Funding is available for up to 1 year and we are
looking for someone to start as soon as possible.

All interested applicants are invited to contact
