Oak Ridge is having hardware problems and I'm going to be traveling
later this month, so the schedule for NA Net Digest in September is,
and will continue to be, somewhat erratic.

Subject: Introduction of SC-Net

For those of you who have access to electronic mail, we are
pleased to announce the formation of a monthly electronic
newsletter for the benefit of the SIAM Supercomputing Activity
Group. Called SC-Net, we expect to transmit this newsletter to
you on or about the first day of each month, beginning this

Our newsletter will be a digest of conference and seminar
announcements, current developments and late-breaking news. If
time-sensitive announcements warrant, we will create mid-month
interim editions. We plan to include highlights from the
electronic newsletter in the quarterly paper newsletter for the
benefit of those without access to electronic mail.

The e-mail address for material submissions is Anyone
can submit material. If you have material for an upcoming issue,
please send it to this e-mail address right away.

Important: In order for the newsletter to reach you, we need
your current Internet electronic mail address. Please send an
e-mail message containing your name and your Internet e-mail
address as soon as possible to:

We hope everyone in the group will contribute to this newsletter.

NOTE! This newsletter will go out to members of the Society of
Industrial Mathematics (SIAM), who are also members of the
Supercomputing Activity Group. To get information on SIAM,
send e-mail to

Join today! We already have about 1,000 members in this activity group.

Subject: NORTIM meeting and Gene Golub Prize

The Nordic Society for Applied Mathematics, NORTIM, has had its 6'th annual
meeting at NTH in Trondheim, Norway last week.

At the meeting we heard contributions from PhD students from Nordic countries,
all of a very high standard. These contributions competed for the Gene Golub
prize, annually presented to the best such contribution.

This year the prize was given to Morten Bjorhus from The Dept. of Mathematics
at NTH for his contribution on "Dynamic Iteration for Time Dependent PDE's".

The comittee wished to recognize the talents and skills of a young Applied
Mathematician who has a great potential for research in Numerical Analysis.

The meeting was followed by minisymposia on
Mathematics in Engineering Education
Numerical Linear Algebra
Statistical Methods in Image Processing
Reliability Theory
Wavelets andrelated topics.

About 80 participated in the meeting and enjoyed the atmosphere in Trondheim
and the quality of the program.

Subject: Automatic Result Verification Conference

Since our last posting, we have received 57 abstracts from 16 countries
for our conference on Numerical Analysis with Automatic Result
Verification, in the areas of Linear Systems, Applications, Arithmetic,
Computing Ranges, Nonlinear Systems, Global Optimization, Automatic
Differentiation, ODE's, PDE's, and others. Additionally, Vladik
Kreinovich has been assembling abstracts for an associated workshop on
Interval Methods in Artificial Intelligence, to be held as an integral
part of the conference.

We have decided to extend the deadline for abstracts (originally August
first), to allow wider participation. In particular, we encourage more
participation from researchers in the western hemisphere. This meeting
will be a chance for colleagues throughout the world to exchange ideas
and views.

Please let me know if you would like a copy of the complete annoucement.

Anyone who wants to give a talk and will not be in the regular
session may do so at one of the Circus sessions. Each session will
begin by asking who wishes to speak and setting the Circus schedule
accordingly. To provide a more informal atmosphere for discussion,
there will also be time set aside for Workshops on specific topics
of interest. The schedule for the Circus and Workshops will be
determined each day according to demand.


Travel and lodging assistance will be awarded to student authors
judged to have the best research papers. Papers containing
original research due mainly to the student must be received before
December 15, 1992. They must be singly authored and may be no more
than 10 pages in length. Sending only an abstract is unacceptable.

A panel of judges selected from the program committee will
determine the best papers. The authors of the three best papers
will be given a travel stipend, free lodging and registration, and
they will be expected to present their papers in a special session
at the conference. A number of other students who participate in
the competition will be awarded free lodging and registration
depending on the availability of funds.


There will be morning and late afternoon lectures of approximately
20 minutes each. Evenings will be reserved for the Circus and
Workshops. Afternoons will be open for more informal workshops and


Potential contributors should submit an abstract of no more than
200 words to:

Copper Mountain Conference Coordinator
Computational Math Group
University of Colorado at Denver
Campus Box 170, PO Box 173364
Denver, CO 80217-3364


TeX or LaTeX is preferred (include any special style or font file
that is used), but plain ASCII is acceptable.
