Subject: Householder Quip

I am interested in tracking down a quip attributed to Householder: he
would be afraid to fly in an airplane designed with floating point
arithmetic. Does anyone know when and where he said this, and what
exactly he said? I asked Nick Higham, who pointed out the following
paper to me, which contains a paraphrase of the quip:

P. R. Turner, "Will the 'real' real arithmetic please stand up?",
Notices of the AMS, 38 (1991) 298-304.

I checked with the Peter Turner, but he does not know the quip's origin
either. If I get additional solid information, I will post a follow-up.

Thanks,
Steve Vavasis (vavasis@cs.cornell.edu)

Subject: Question on PDE with Robin Boundary Conditions

I am investigating a-posteriori error estimators for the Finite
Element Problem and the Poisson equation. In addition to Dirichlet
and Neumann boundary conditions, I am also interested in boundary
conditions of the third type (Robin BC.)

d u/ d n = alpha*(g3 - u)

Such a boundary condition is mentioned only in few papers, and
an analysis is even more rare. My own investigations led to
formulae and error bounds which are much less convenient than
for Neumann BC.

Thus I would like to know whether Robin BCs constitute a severe
problem, or if results only have not been published.

Subject: SPEC Awards Program

The SPEC CPU98 benchmark awards program continues for three more months.
To date more than 25 submissions have been made with a large
number of them being considered. The award program is open ended,
with awards going to any of number candidates, depending on quality.
The submittor must supply source and have the right to submit the
source to SPEC.

It is open to application programs in a wide variety of fields.
Applications employing sparse matrix or gather/scatter matrix
operations and the eigenvalue problem are three areas where the number
of submissions is still somewhat meager.

The focus of the awards program is toward end user applications.
For example a circuit simulator is preferred over a program that
just does matrix inversions. Larger (in terms of lines of code
and memory utilization) applications are preferred over smaller
applications.

Submissions can be made by going to:

http://www.specbench.org/osg/cpu98/search.html

If there are further questions on this program, please feel free to
contact me via email bodo@eng.sun.com.

Subject: New Book, Galerkin Finite Element Methods for Parabolic Problems

New Book Information

Vidar Thomee, Chalmers University, G=F6teborg, Sweden

Galerkin Finite Element Methods for Parabolic Problems
Springer Series in Computational Mathematics. Eds.: R.L. Graham; J.
Stoer; R. Varga. Vol. 25

This book surveys the mathematics of Galerkin finite element method as
applied to parabolic equations. The approach is based on first
discretizing in the spatial variables by Galerkin's method, using
piecewise polynomial trial functions, and then applying some single step
or multistep time stepping method. The concern is stability and error
analysis of approximate solutions in various norms, and under various
regularity assumptions on the exact solution. The book gives an
excellent insight in the present ideas and methods of analysis rather
than pursuing each approach to its limit. It is essentially
self-contained, and simple model situations make it easily accessible
even for beginners in the field. Its basis is the author's LNM volume
1054 of 1984, which has been substantially amended.

It is a coordinated effort to produce a general purpose library of parallel numerical software suitable for a wide range of computationally intensive industrial applications and to port several application codes which use this library to parallel computers. The basis of the coverage of the library has been determined by the requirements of the end-user applications and its principal objective is to produce a library of parallel numerical software that meets the following requirements: * the problems addressed by the library should be relevant to a wide range of industries, * the library should be portable and efficient across a wide range of parallel machines, * the numerical algorithms must be accurate, stable and robust, * the software and documentation should be produced to commercial quality and should meet recognized standards and pass strict quality control processing. Almost all of the numerical software included in the library will be tested for accuracy and stability using an existing tool, PRECISE. PRECISE is based on well-understood theory and the project will bring PRECISE to a mature and commercial quality. Target machines for the project will range from low cost networks of workstations that are common in SMEs to high-end distributed memory parallel computers. For more information, see the project web-page: http://extweb.nag.co.uk/projects/PINEAPL Workshop Themes: The workshop will provide a forum to discuss progress on enhancing the number of applications that can take advantage from the PINEAPL Project results. The workshop will be of interest to: * practitioners from industry with applications which embed numerical computation, * hardware vendors who would like to have quality parallel mathematical software implemented on their parallel systems, * researchers who are interested in application areas and numerical algorithms for high-performance computing.

Currently, there are a dozen mathematics faculty who identify themselves as applied mathematicians and several other faculty in and out of the department who work in applied areas and are loosely associated with CAM. The Purdue Mathematics Department is committed to deepening and expanding its contributions to research and education in applied mathematics. Because of its solid foundation and the support of the school and university administrations, the department is well positioned to achieve its goals in this area. The Director should be a senior full professor or distinguished professor of mathematics with the stature and experience to lead outstanding research and educational programs in applied mathematics. In addition to carrying on a strong research program in her or his own area, the Director will be expected to coordinate the development of other applied areas in the department, facilitate research contacts between mathematics faculty and faculty in other departments, oversee the applied mathematics visitor and seminar programs, and help create an atmosphere in which the educational programs of graduate students and post-doctoral staff in applied mathematics can flourish. To this end, the Purdue Mathematics Department seeks applicants for the position of Professor of Mathematics and Director, Center for Applied Mathematics, with a strong national reputation in research in applied mathematics, proven ability to work with graduate students, post-docs, and colleagues, a record of funding success, and flexibility in pursuing opportunities.
