Subject: Simple handling of IEEE exceptions on SUN
Here is what I put at the beginning of every program on SUN to see
where it went wrong instead of having Inf's and NaN's propagate:
external abort,ieee_handler
integer i,ieee_handler
i=ieee_handler('set','division',abort)
i=ieee_handler('set','overflow',abort)
i=ieee_handler('set','invalid',abort)
Every IEEE machine should come with a simple flag on the compiler that would
cause abort if floating point exception occurs, just like the three lines
above do. In fact, it should be the DEFAULT so that those of us who do not
want to worry about NaN's do not have to.
Thanks to Joe Grcar for bringing this common gripe up!

While there is a machine epsilon, it is extremely difficult to determine
it using regular programming techniques, especially with the compiler
optimizations being used today. What you will get is the unnormalized
epsilon, while what is generally "wanted" is the normalized epsilon.
Codes I have seen lately have resorted to setting epsilon in a
DATA statement (or C equivalent), which is non-portable.

I sympathize greatly with Joe Grcar - porting/creating/checking software
is made extremely difficult by the propagation of NaN/INF values.
The problem is not IEEE arithmetic, or anybody else's arithmetic;
the "villains" in this are the compiler vendors who set the compiler
default behaviour, and don't supply compiler switches to easily
modify the default behaviour (calling vendor-specific routines or
otherwise hacking on the source code is not an acceptable alternative
since this creates non-portable code).
Why anyone would want a default behaviour to allow a program to
continue executing after dividing by 0 (either integer or floating
point), or creating a NaN by whatever means (e.g. fp overflow), is
beyond me. In my many years of programming, I can't think of one
case where I would want this to happen. Performing such operations
is a clear indication of a program(mer) error, and I want to know about
it right away, not hours/days later when the job finishes printing
pages of NaNs, when debugging has become next to impossible.
It may be much more efficient for the cpu to deal with exceptions
automatically rather than trapping (and blowing away the instruction
pipeline), but it doesn't help the user much.
If IEEE specified the default behaviour to be "carry on regardless",
then the committee responsible for this doesn't live in the real world.

Subject: Complexity of Matrix Multiplication
We all know how to count operations. Clearly, for example, squaring
an n x n matrix requires n cubed multiplications, i.e., n squared inner
products of length n. For the last fifteen years or so, this clarity has
been quite suspect. Many algorithms have been proposed that lessen the
computational burden below order n cubed.
Some are clearly impractical. I would like to ask " given no more
than n processors, assuming practical communication overheads and storage",
what is the lowest parallel time for squaring a dense matrix. The practical
answer should be implementable on the current generation of machines
(Paradox, CM-5, SP-1, Meiko, etc.) using current software. I don't need
to implement this just now but do have an interest in the answer.

Subject: Brazillian Society for Applied and Computational Mathematics
XVI Congresso Nacional de Matematica Aplicada e Computacional
Universidade Federal de Uberlandia, Brazil
6 - 9 September 1993
The annual conference of the Brazillian Society for Applied and
Computational Mathematics was held this year in the charming city of
Uberlandia, some 500km North West of Rio de Janiero. The
plenary lecturers were U. Ascher, J. Butcher, G. Golub, J. Mackenzie,
M. Maierallo, J. Martins, R. Ohayan and R. Sampaio and the overall programme
included also 14 one hour lectures, several panel discussions, and a large
number of research seminars organised into 17 main divisions. Four
mini-courses, intended mainly for graduate students, had the titles
Computational Matrix Algebra, Introduction to Computational Fluid
Dynamics, Ecological Mathematics and Introduction to Supercomputing.
The local organising committee was chaired by the remarkable Celia A. Z.
Barcelos. Professor Barcelos seemed to be able to do many things
simultaneously, from attending to many strands of essential organisation
to entertaining the many guests to her University. Some nice features
of the conference, amongst many, were the large number of graduate
students taking part and the elegant certificates of participation
personally signed by Julio Clayessen, the President of the Society.
Interspersed with the scientific programme were some enjoyable
musical events. I tried, without much success, to teach myself some
basic Portuguese before going to Brazil but it was unnecessary
because the use of English is generously accepted. The only phrase
that seemed to me to be essential was "tudo bem" (pronounced like
tuda bay with the last vowell nasal). It means "all's well" and
sums up my lasting impression of the conference, the cuisine, the
warm and friendly people, and the country as a whole.

INTRODUCTION
The aim of this IEEE Workshop is to bring together
researchers and practitioners working in Academia, Government and
industry. Particular emphasis will be placed on ``The Curse of
Dimensionality'', i.e. the extreme dimensionality of computations
connected with the implementation of theoretically optimal
mathematical procedures of inference and decision making.
TOPICS
The extreme dimensionality of computations connected with
implementation of theoretically optimal mathematical procedures
of inference and decision-making is a serious obstacle in a
variety of fields such as control, signal processing, image
reconstruction, pattern recognition, nonparametric estimation,
expert systems etc. The ``curse of dimensionality'' has often
been cured by just 'ad hoc' simplifications at the cost of
losing a lot from the theoretical properties of the optimal
solution. Recent progress in attacking high-dimensional
problems in the above mentioned fields makes us believe that
it is the right time to think of picking up widely applicable
principles and methods of handling or at least approaching the
problem. The key idea of the Workshop is that the problem is
common to a number of different disciplines such as control theory,
mathematical statistics, system identification, information
theory, statistical mechanics, artificial intelligence (to name
a few), and that we can and we should learn from each other.
Because of the strongly inter-disciplinary character of the
Workshop, we plan to give a considerable space to invited
lectures by leading specialists in various fields. The Workshop
will further include several sessions of contributed papers,
poster sessions and computer demonstrations.
- Parallel algorithms and architectures
- Neural nets
- Model reduction
- Finite-dimensional estimation, filtering and control
- Complexity
- Multivariate integration and optimization
- Non-traditional approaches

IMACS WORKSHOP ON
(THEORETICAL AND COMPUTATIONAL ASPECTS OF)
TURBULENCE
Rutgers University, New Brunswick, NJ, USA
February 10-11, 1994
In order for CFD to get to new levels of usefulness to industry, there
is a need for better turbulence models for high Re flows. An honest
appraisal by industry on needs, and a similar word by academia and
researchers at national labs on what can be done now is probably
necessary. The workshop will deal with the numerical analysis and CFD
algorithms that could bridge the gap, and will include those aspects
of turbulence theory that have relevance to modeling used in
simulation. Topics to include: Modeling, Non-equilibrium Turbulence,
Spectral and High Order Methods, Adaptive Grids, Lagrangian Methods,
Ocean Dynamics. It is currently planned to have proceedings published
after the workshop, and a special issue of the IMACS journal APPLIED
NUMERICAL MATHEMATICS will be devoted to this meeting.

HONG KONG BAPTIST COLLEGE
Department of Mathematics
Department of Computing Studies
Baptist College provides whole-person education leading to bachelors, masters
and doctoral degrees. Beginning in September 1994 the Mathematics and
Computing Studies Departments will jointly offer an MSc degree in Scientific
Computing. Due to this expansion we anticipate openings for 2-3 experts in
scientific computing within the coming two years.
At present the Mathematics Department has 12 teaching staff and the Computing
Studies Department has 17. Staff engage in undergraduate and graduate
teaching, supervision of project students, research and some administration.
Since we are a growing institution, all staff have the opportunity to
participate in developing our academic programs. As a publicly funded
university-style institution Baptist College offers salaries and benefits
(medical, housing and education) comparable to other Hong Kong tertiary
institutions.
Applicants should have a PhD and be committed to teaching and research in an
interdisciplinary environment. If you wish to apply, please send your CV and
three confidential letters of reference to the Personnel Department, Hong Kong
Baptist College, 224 Waterloo Road, Kowloon, HONG KONG. Inquiries may also be
made to the Fred J. Hickernell, Head of Mathematics (at Department of
Statistics, Stanford University through January 31, 1994), Email:

Subject: Position at Old Dominion University
Old Dominion University
Computer Science Department
The ODU Computer Science Department solicits applications for an
anticipated junior-level tenure track position starting as early as
January 1, 1994. A PhD in Computer Science or a related field, a
research record in high performance computing and communication, and
excellence in teaching are required.
The atmosphere of the department is strongly supportive of research,
with an active faculty of 17 and over 100 graduate students. The
department has over 100 SPARC workstations and special equipment needs
can be accommodated. NASA's Langley Research Center, ICASE, and DOE's
CEBAF facility are all within a thirty-minute drive from campus.
Salary is competitive with the best. We would like to receive
applications by September 25, 1993 but will continue to consider
candidates until the position is filled. To apply, send curriculum
vita, copies of recent articles or technical reports, and the names of
three to five references to:
Kurt Maly
Kaufman Professor and Chair

Old Dominion University is an Affirmative Action/Equal Opportunity Employer.
[Submitter's note: An antecedent to this announcement with less
specificity in the research area ran in the September issue of the
Communications of the ACM. The university has since then designated
HPCC as one of five strategic areas that align with ODU's current
strengths and natural geographical advantages; therefore, the search has
been prolonged and the NA-net audience targeted. I would be glad to
respond by e-mail to questions about the search from potential
candidates. Actual candidates should contact Prof. Maly directly.

AIMS AND SCOPE
OPTIMIZATION METHODS AND SOFTWARE publishes refereed papers on the
latest developments in the theory and imple<mentation of optimization
methods, with particular emphasis on the interface between software
development and algorithm design. Topics include:
* Theory, implementation and performance evaluation of algorithms and
computer codes for linear, nonlinear, discrete, nonsmooth and
multicriteria optimization and optimal control.
* Algorithms and software for solving systems of nonlinear equations
and the numerical study of parameter dependent operators and their
discretizations.
* Parallel optimization algorithms.
* Various aspects of efficient and user-friendly implementations:
e.g. automatic differentiation, error sensitivity and validity
analysis, problem scaling and stopping criteris and symbolic/numeric
interfaces.
