Subject: A Great Little Book

SIAM has just republished a great little book. It is "Numerical
Analysis: A Second Course" by Jim Ortega. It does not describe
numerical methods but the book gives the fundamental ideas behind
numerical mathematics. It should be required reading for all graduate
students in scientific computing.

The book is in paperback and the cost to SIAM members is about $20.
You might try ordering it by e-mail ( will

Subject: Parallel Circus

Final Announcement
for the
Seventh Parallel Circus

March 30-31, 1990 at Stanford University

The Parallel Circus is an informal conference focusing on
parallel scientific computing. A strength of the Circus is
the discussion of current research topics and a healthy mix
of industrial and academic participants.

Continuing the tradition that began at Yale in 1986, the
Research Institute for Advanced Computer Science (RIACS)
and Stanford University are jointly hosting the Seventh
Parallel Circus at Stanford on Friday and Saturday,
March 30-31, 1990.

This is the first time the Circus will be held outside of
the Northeast, and we hope to have many attendees from
around the country as well as those who have been

A partial list of titles of talks from people who have
registered is below:

"Incremental Condition Estimator for Parallel Sparse Matrix

"Cyclops: A Stochastic Bayesian Approach to Stereo Matching"

Subject: Position in Sweden in Computer Graphics and Visualization

Hello there,
I would very much appreciate if you could make this announcement known
to as many people as possible (via email, newsletter, etc).
Thank you in advance. If you are interested to apply for the position
or for a visiting position so do not hesitate to contact me.

Dead-line is March 31, 1990.

Regards, Bo Kagstrom

Announcement of SWEDEN's first chair as professor in
Computer Graphics and Visualization in Scientific Computing
at University of Umea in Sweden

Umea university is a young university that lies at the mouth of the
river Ume, equidistant from both the capital, Stockholm, and Sweden+s
most northerly town Kiruna. Today the campus has some 3 000 employees
and 11 000 students. The university has achieved prominence in many
fields, of which bio-technology, environmental ecology and information
technology are some of those in which now intensive activity is taking

Expertise in the field of information technology in its broadest sense
is rapidily growing and in certain areas such as Scientific computing
great progress has already been made, and international collaboration
established, primarily with European and American researchers.
A couple of years ago a special action program for Information technology
- Scientific Computing was established at the faculty of Mathematical
and Natural Sciences. The program aims towards development of advanced
methods, algorithms and software in Scientific computing for different
parallel computer architectures.

The university is together with the Technical University of Lulea,
the Institute of Space Physics i Kiruna and the Industrial Development
Center in Skelleftea, founder of Supercomputer Center North (SDCN).
SDCN is one of two national centers for supercomputing in Sweden and
is connected to all swedish universities through the Swedish University
Network (SUNET). Thereby scientists have access to an IBM 3090-600 E/VF,
placed in Skelleftea, soon to be upgraded to a 600 S-model.

At the university we have a distributed-memory multiprocessor-system
Intel iPSC/2 hypercube with 64 nodes of which 16 nodes have a vector
facility and are about to aquire a shared-memory multiprocessor-system
with both high-performance computing power and advanced graphic
facilities for visualization.

Due to the partnership in SDCN Sweden+s first chair as professor in
Computer Graphics and Visualization in Scientific Computing is now
established at the university.

The field is very wide and interdisciplinary to its nature and candidates
for the chair can have different scientific profiles ranging from
research in tools and methods for Computer Graphics and Visualization
in Scientific Computing to graphics computing and visualization in
Scientific Computing with an emphasis on applications from biology,
biotechnology, chemistry, physics and medicine.
At the university we have applications/possible applications in for
instance biotechnology - molecular biology, chemometry, environmental
chemistry, geographical information systems, industrial design,
medicine, physical chemistry, psychology, theoretical physics and
space physics.

The professorship is placed at the department of Computing Science.
At the department there are professors in numerical analysis, computer
science, and numerical analysis and parallel computing.
Since a couple of years there has been an intense development of knowledge
in the fields of parallel computing and environments and tools for
parallel computer architectures.

The university now announces a professorship in Computer Graphics and
Visualization in Scientific Computing as vacant, reference number
DNR 321-189-90. Notice that the reference number must be mentioned on
the application.

To get started in the field as soon as possible the position can also be
a visiting professorship.
Send the application to University of Umea, S-901 87, Sweden before
the 30th of March 1990. Enclosed to the application should be curriculum
vitae, short summary of scientific and educational work, and publications
and ev interest of a visiting professorship. Everything in 4 copies!!

Questions will be answered by Professor Bo Kagstrom, Dept of Computing
Science, Umea University, S-901 87 Umea, phone +46-9016 54 19,
