Subject: Jim Wilkinson's definition of a sparse matrix

In an earlier NA Digest posting, I requested information about Jim Wilkinson's
informal (but useful) definition of a sparse matrix. I received replies from
Jim Bunch, Iain Duff, Cleve Moler, John Reid, Yousef Saad, and Rob Schreiber.
Based on their input, here is what I have found:

Wilkinson defined a sparse matrix as "any matrix with enough zeros that it
pays to take advantage of them" [1]. Wilkinson seems to have never published
this definition in writing. According to Jim Bunch, Wilkinson stated this
definition as early as 1969, at Argonne. I have not found any printed versions
of this definition earlier than those of Iain Duff [2] and John Reid [3], who do
not cite Wilkinson and elaborate more fully on the definition. It may have arisen
independently. What is certain is that by the early 1970's, it was the common
understanding in the sparse matrix community that defining a sparse matrix as
a matrix with some fraction of nonzero entries was inappropriate. Instead,
it was recognized very early that sparsity is an economic issue; if you can
save time and memory by exploiting the zeros, then the matrix is sparse.

Subject: Those poor indices and their last defense!

Dear Colleagues,

In my earlier posting I said that those poor indices represent important
geometric and physical quantities. It was rebuffed with a semantic
argument by the esteemed academic colleague, stating the fact that not
the "i" indices but the "x(i)" entities represent those important
quantities. My point exactly: one cannot access a specific "x(i)"
quantity without dealing with the corresponding "i" index. It may have
been better to use reference, instead of represent, but there is no
misconception here at all.

The misconception might be in the start of the discussion as MATLAB
versus FORTRAN. In my opinion, this is really a discussion on a "use a
tool" versus a "make a tool" based teaching. As a matter of fact you can
do both in a MATLAB environment if you restrict the students to write an
LU factorization and not just use the LU in MATLAB. It is not an issue
of the formal language aspects of the indices either. It is an issue
related to their conceptual role in the training of computational

We need the new generation of computational professionals to understand
the reasons why the Gaussian or Chebyshev numerical integration
procedures are superior to the Newton-Coates class and to see the common
concept in Richardson's, Romberg's or Aitken's techniques. We need
professionals to be able to implement a predictor-corrector multi-step
technique directly advantageous to a particular problem and to
understand the distinction between finite element basis and shape

Instead, we are getting professionals trained in using a canned
Simpson's rule (easy to remember after the TV show), or a Runge-Kutta
function. We are getting professionals who are well versed in their
professor's favorite tool (like MATLAB) and able to "push buttons" on
those tools. The fact is that we have to interview dozens of candidates,
with advanced degrees from excellent schools, for a numerical methods
development position before finding one who is experienced with those
poor indices.

Despite my almost 35 years of industrial experience, I may still
misunderstand the needs of the industry; after all, industry is full of
changes and surprises. As some of you may notice, my last posting to
this forum two weeks ago was from a large American company and now I am
posting from a very large German company, while never leaving my office
or changing my work. Therefore, I will not be surprised if the apparent
index agnostic sentiments blow away those poor indices from the horizon.

Subject: Re: Fortran vs Matlab

Wolfgang Bangerth <> wrote

.... It therefore seems to me that by teaching Fortran instead
of a more modern programming language, we prepare our students
more for conservation of old codes than for the more far sighted
maintenance and creation of current and future codes.

This illustrates a common misperception: That Fortran has not changed
since 1957. This is, of course, perpetuated by computer science
professors who are eager to say that they're proud not to have looked at
Fortran since 1966. In fact, since its first standardization in 1966,
Fortran has been revised four times, and a fifth revision is being
prepared for publication in 2008.

Fortran 2003 is a fully object-oriented language, the development of
which paid careful attention both to the preservation of investments in
legacy code and the goal of continuing to allow processors to produce
efficient programs. Contrast this with the revision of C, which
produced an incompatible language that leads to excessively high
lifetime ownership costs (if you believe Les Hatton's studies).

Fortran 2008 will include Co-Array Fortran, a method for programming
SIMD applications that is far simpler than any of the procedure-based
methods such as PVM or MPI, which will significantly reduce labor costs.
Comparisons of selected applications at Cray, based upon preliminary
implementations, have shown performance improvements up to a factor of
three. The C community is developing a similar paradigm, called UPC,
but there are no plans to integrate it into the C language, since the C
language committee has put itself in "maintenance" mode, i.e., they do
not intend to publish a revised language standard.

So dismissing the teaching of Fortran as some form of archaeology that
has no place in the modern world is more a sign of ignorance than

Symbolic-Numeric Computation 2007 (SNC 2007)
July 25-27, 2007 -- London Canada
C A L L f o r P A P E R S
Algorithms that combine ideas from symbolic and numeric computation have
been of increasing interest over the past decade. The growing demand for
speed, accuracy and reliability in mathematical computing has accelerated
the process of blurring the distinction between two areas of research that
were previously quite separate.
The goal of the present workshop is to support the interaction and
integration of symbolic and numeric computing. Earlier meetings in this
series include the SNAP 96 Workshop, held in Sophia Antipolis, France,
and the SNC 2005 meeting, held in Xi'an, China. Following the tradition,
Symbolic-Numeric Computation 2007 will be held July 25-27 in London, Canada.
SNC 2007 is affiliated with the 2007 International Symposium on Symbolic and
Algebraic Computation (ISSAC 2007). Co-located with this workshop will be
PASCO 2007, the 2007 International Workshop on Parallel Symbolic Computation.
SNC and PASCO will be held immediately prior to the ISSAC 2007 meeting, both
at the University of Western Ontario, Canada. ISSAC 2007 will be held
nearby in Waterloo, Canada.

Call for Papers:
The program of SNC 2007 will include invited presentations, contributed
research papers and posters. Specific topics include, but are not limited
* Hybrid symbolic-numeric algorithms
* Approximate polynomial GCD and factorization
* Symbolic-numeric methods for solving polynomial systems
* Resultants and structured matrices for symbolic-numeric computation
* Differential equations for symbolic-numeric computation
* Symbolic-numeric methods for geometric computation
* Symbolic-numeric algorithms in algebraic geometry
* Symbolic-numeric algorithms for nonlinear optimization
* Numeric computation of characteristic sets and Gr�bner bases
* Implementation of symbolic-numeric algorithms
* Model construction by approximate algebraic algorithms (e.g. numerical
sparse interpolation, the approximate Buchberger-Moeller algorithm)
* Applications of symbolic-numeric computation

The conference invites submission of papers presenting original research,
either in the form of extended abstracts (4 pages) or full papers
(up to 16 pages in 11 point font). A paper template is available at .

Doctoral Studentship in Optimization in Reservoir Simulation and
Oilfield Operations

Oxford University Computing Laboratory (OUCL) in conjunction with
Schlumberger has received an EPSRC CASE award to fund a D. Phil.
studententship for research into optimization problems arising from the
oil industry. In particular, oil recovery from geological formations
leads to a variety of very challenging, large-scale optimization
problems. Of increasing interest is the question of optimization in the
presence of uncertainty. The function to be optimized is frequently
very expensive to compute, and approaches using less-expensive
surrogates are to be preferred. The proposed research will concentrate
on the development and analysis of robust optimization techniques for
such cases, and on their application to problems of interest to

The project will be co-directed by Professor Nick Gould from the
Numerical Analysis Group at OUCL and Dr. Chris Farmer from Schlumberger.
The student will spend time both in Oxford and at the Schlumberger
Abingdon Technology Centre. The research techniques will include
numerical experimentation to try to identify characteristic correlation
structures that might then determine the best algorithm(s), and
theoretical convergence investigations, using methods from numerical and
functional analysis. Training will be provided both in relevant
numerical techniques and on modeling techniques relating to the oil

It is hoped that the student will spend enough time with Schlumberger to
investigate optimization in at least two problem areas; optimization
involving flow through porous media and optimization of surface pipe
networks with pumps and compressors. The student will be supported by
Schlumberger software developers in this ambitious project and will be
expected to focus on the research questions rather than on software
production. Nevertheless, the student will be encouraged to develop
software. For further details, see

experimentation to form the three pillars of scientific discovery and
technological design. Computational Science can be viewed as residing
at the intersection of mathematics, computer science, statistics,
engineering, and the sciences. Examples of problems in Computational
Science that are common to these disciplines include algorithm
development and analysis, multiscale techniques, scientific
visualization, data mining, etc. Due to the interdisciplinary nature
of Computational Science, it is essential that a computational
scientist be trained in an interdisciplinary setting. The SCS is
uniquely positioned to offer such training because it has a truly
multidisciplinary faculty consisting of chemists, biologists,
computer scientists, engineers, geophysicists, mathematicians,
physicists, and statisticians, with an even broader spectrum of
disciplines to be represented in the future.

Students enrolled in the Ph.D. program in Computational Science can
choose several areas of specialization. In addition to the major
track, which trains students interested in the mathematical and
computer science aspects of computational algorithms that can be
applied to a wide range of disciplines, we offer tracks in
atmospheric science, biochemistry, biological science, geological
science, materials science, and physics. Soon, we hope to add a track
in Validation and Verification. Students following these tracks gain
expertise in computational issues specifically related to the chosen
field. All students, however, will be involved in truly
interdisciplinary training and research.

The SCS maintains a large and diverse computing infrastructure in
support of research and education. Computing resources at the SCS
include supercomputers, a number of clusters and computational
servers, a laboratory for scientific visualization, a bioinformatics
server, and more. The SCS Visualization Laboratory provides high-
powered visualization resources to the FSU community for research,
data analysis of large data collections, and education.

Florida State University is a national graduate research university
which has built a reputation as a strong center for research in the
sciences. It is located in Tallahassee, FL which is situated in the
Florida panhandle and is near some of the most beautiful, uncrowded
beaches in the United States as well as other scenic wonders.

Applications are being accepted now for Fall 2007. The SCS has a
number of assistantships available for qualified individuals.
Minorities and women are especially encouraged to apply. Applicants
should hold a baccalaureate degree in computer science, mathematics,
statistics, engineering, or a natural science. The interested
applicant should submit an on-line application to the SCS
an application to the Florida State University
plus supporting materials which include GRE general test scores,
official transcripts, and three letters of recommendation.

Subject: MSc in Applied Mathematical Modelling and Scientific Computing

University of Greenwich
MSc Applied Mathematical Modelling and Scientific Computing

The MSc programme is run by the Department of Mathematical
Sciences, ranked at 10th in the UK departmental ranking,
which is a part of the School of Computing and Mathematical
Sciences and takes students in both October and January.

This Masters programme is aimed at training and equipping
Honours graduates in engineering, science or mathematics
and suitably qualified professionals, with the skills required
to understand, and use, Applied Mathematical Modelling and
Scientific Computing technologies in industry. Emphasis will
be placed on modelling phenomena governed by the physics of fluid
flow, heat transfer, electromagnetics and solid mechanics. A core
philosophy of the programme is to introduce the students to the
concept of multi-physics modelling, where interactions between
the governing physics, and hence the relevant solution and software
technologies, are important. Details of major and optional courses
may be found from the above CSE web site.

Entry requirement: A good Bachelor degree in engineering, physics,
mathematics or relevant related discipline. Those who have
substantial commercial or industrial experience but lack formal
qualifications should seek an interview with the programme leader.

CTA (Collaborative Training Awards): Up to eight EPSRC CTA
studentships is allocated to this MSc programme in Applied
Mathematical Modelling and Scientific Computing only to
the best qualified candidates.

Further details of the programme, applications, enquiry should
reach (Mrs. Marilyn Nichols) or

Programme leader - MSc AMMSC
