Subject: Ten Digit Algorithms
I have written an essay, presented as the Mitchell Lecture at the
recent Dundee meeting, that advocates the production of Ten Digit
Algorithms, defined by the conditions "Ten digits, five seconds,
and just one page". The essay comes with 32 Matlab examples.
I imagine these views may provoke some strong reactions among NA
Digest readers. Would interested parties like to take a look at
http://web.comlab.ox.ac.uk/oucl/work/nick.trefethen/tda.html and
send me any comments? If the responses are interesting I may post
a follow-up note later on.

Subject: Special Issue of Computational Optimization and Applications
Special issue of Computational Optimization and Applications on
LINEAR ALGEBRA ISSUES ARISING IN INTERIOR POINT METHODS.
Linear algebra is a really important topic in the effective implementation of
Interior Point algorithms. In fact, most of the recent papers and talks on IP
methods focus on linear algebra issues, such as preconditioning techniques, ad
hoc factorizations and iterative methods and their critical role in effective
IP implementation. We therefore plan to edit a special issue of Computational
Optimization and Applications on
LINEAR ALGEBRA ISSUES ARISING IN INTERIOR POINT METHODS.
We invite you to submit a paper on such topic by September 30 2005. All papers
will be peer reviewed according to the journal standard, by the end of December
2005. Papers should be submitted to any of us, and marked LA-IPM.
To facilitate the processing electronic submissions in either LaTeX, PostScript
or PDF are encouraged. Early submissions are welcome.

Subject: Postdoctoral Position at University of Minnesota
POSITIONS AVAILABLE: Postdoctoral Associate
at the Department of Computer Science and Engineering,
University of Minnesota
A Postdoctoral Associate position is available to work on research
projects related to numerical linear algebra methods in computational
materials science. These projects involve high performance algorithms
(e.g., solving very large eigenvalue problems) in the study of
electronic structures of materials.
Applicants must have a good background in numerical linear algebra and
parallel scientific computing. Knowledge of numerical methods in
quantum mechanics is a plus but it is not required. Familiarity with
partial differential equations, domain decomposition techniques,
sparse matrices, iterative methods for linear systems and/or
eigenvalue problems, is very desirable, as is experience with parallel
programming. A Ph.D. in Computer Science or in any field related to
scientific computing is required.
Send application materials, including the names of up to 3 references,
by e-mail to saad@cs.umn.edu. There is no deadline for applying - but
the selection process will begin one month after the posting of this
announcement and the position will remain open until it is filled.
The University of Minnesota is an equal opportunity educator and
employer.

Subject: Postdoctoral Position at Leeds
We currently have a position for a Post-Doctoral Research Fellow in
Parallel Numerical Algorithms for a period of three years. The post is
available from October 1st (or as soon after as possible) and the
appointee will work on a project entitled "Self-Adapting Software for
Grid-Based Numerical Simulation" in the School of Computing at Leeds.
The general area of research will be parallel multilevel algorithms for
the solution of PDEs using finite difference and finite element
discretizations. The key issues to be investigated relate to the
development of techniques and algorithms to produce automatically adapting
software for parallel and distributed computing on computational Grids.
Amongst others, this will require the development of: dynamic
load-balancing procedures that are able to respond to observed behaviour
on a given computational node; different partitioning and parallelisation
techniques that are best suited to different architectural
characteristics; reliable computational models, whose parameter values may
be easily established at run time, in order to predict the most efficient
execution format for the hardware encountered, and; novel algorithms for
dealing efficiently with the high latency issues arising when simulations
are undertaken across more than one Grid resource.
For further details of the project and information on how to apply please
visit:
http://www.comp.leeds.ac.uk/pkj/ParallelNumerical.html
The closing date for applications is September 5th 2005.
