Subject: Good Math Software in ADA ?
Our Math Library people have recently had a number of requests for
standard software capabilities in ADA rather than Fortran. Does
anyone out there in na-net-land have a good handle on the state
of conversion of good algorithms and packages (especially linear
algebra) to ADA?

Subject: Navier Stokes for Speech Synthesis
I am presently in the Eng. Dept. at Cambridge U. working in
the area of speech synthesis. I am trying to model the vocal
tract using the Navier Stokes eqs. Multigrid is method I
would like to use on the discretized (finite difference)
eqs. and Newtons iteration for linearization.
I understand that you might be able to give me some help in
finding existing programs that might be of use to me. I
would prefer to work in 'C' but Fortran would be OK; I
believe there is are programs that can convert Fortran into
a pseudo 'C' code.
I would be extremely grateful for whatever assistance you
can offer.
Thanks,
Hibbert Duncan

Subject: Internet Connection at University of Southwestern Louisiana
My institution has just installed an Internet connection, which is
a continuous connection at 56 Kilobaud; it supersedes our CSNet connection,
which was a phone line connection at 1200 baud, for two hours in the
middle of the night.
My INTERNET address is:
rbk@usl.edu
If you automatically reached me before at rbk@usl.edu, then there is
nothing new to be done. However, if you used an explicit address, then
you should now access me through INTERNET at the above address, instead
of through CSNet (This includes mailings from monitored discussion
groups, such as Digests.)
The new connection should greatly facilitate exchange of electronic
versions of technical reports, of test problems, and of software
(such as new versions of INTBIS), as our bill is no longer proportional
to the volume of traffic.
I'm looking forward to further correspondence.

Subject: Householder Fellowship at Oak Ridge
HOUSEHOLDER FELLOWSHIP IN SCIENTIFIC COMPUTING
Mathematical Sciences Section
Oak Ridge National Laboratory
The Mathematical Sciences Section of Oak Ridge National Laboratory
(ORNL) invites outstanding candidates to apply for the 1990 Alston S.
Householder Fellowship in Scientific Computing.
In recognition of the seminal research contributions of Dr. Householder
to the fields of numerical analysis and scientific computing, a
distinguished postdoctoral fellowship program has been established at
ORNL and named in his honor. The Householder Fellowship is supported
by the Applied Mathematical Sciences Subprogram of the U.S. Department
of Energy.
The purposes of the Householder Fellowship are to promote innovative
research in scientific computing on advanced computer architectures and
to facilitate technology transfer from the laboratory research
environment to industry and academia through advanced training of new
computational scientists. The Householder Fellowship is for a term of
one year, renewable for a second year. Benefits of the Fellowship
include a competitive salary, fringe benefits, travel opportunities,
access to state-of-the-art computational facilities (including both
parallel architectures and high-performance personal workstations), and
collaborative research opportunities in a very active research program
in advanced scientific computing. Competition for the appointment is
open to U.S. citizens and permanent residents. Applicants should have
completed a doctoral degree in computer science, mathematics, or
statistics within three years prior to the appointment and have a
strong background and research interest in large-scale scientific
computing.
The Mathematical Sciences Section of ORNL has research programs in
Computational Mathematics, Computer Performance Characterization,
Applied Analysis, and Computational Statistics. The precise research
emphasis of the Householder Fellow would necessarily depend to a great
degree on the research interests of the selected Fellow. Areas of
particular interest at ORNL, and in which applicants would be
especially encouraged, include:
1. Computational linear algebra, with special emphasis on sparse matrix
computations on advanced computer architectures.
2. Partial differential equations, with special emphasis on the
development of novel algorithms for solving mathematical problems arising
in environmental cleanup, such as fluid flow through porous media.
3. Tools for the development and analysis of parallel programs,
including programming environments for parallel computers and methods
for measuring and modeling the behavior and performance of parallel
algorithms.
4. Computational statistics, with special emphasis on the development
of procedures and algorithms for use in the design and analysis of
computational experiments, computer-aided experimental design, and
large-scale statistical problems.
5. ``Grand Challenges'' in computational science, emphasizing the use
of advanced computer architectures to solve important problems in
science and engineering in which fundamental breakthroughs are
dependent on unusually large computational requirements that tax the
capacity of current supercomputers.
Applicants should send a resume, statement of research goals, and the
names of three references to James Atherton, PhD Employment, Oak Ridge
National Laboratory, P.O. Box 2008, Oak Ridge, TN, 37831-6216, marked

[Editor's note: Sorry 'bout that. -- Cleve ]
CONPAR 90 / VAPP IV Joint Conference on Vector and Parallel Processing
Swiss Federal Institute of Technology ETH
Zuerich, Switzerland
September 10-13, 1990
The past decade has seen the emergence of the two highly successful series
of CONPAR and of VAPP conferences on the subject of parallel processing.
The Vector and Parallel Processors in Computational Science meetings were
held in Chester (VAPP I, 1981), Oxford (VAPP II, 1984) and Liverpool (VAPP
III, 1987). The International conferences on Parallel Processing took place
in Erlangen (CONPAR 81), Aachen (CONPAR 86) and Manchester (CONPAR 88). The
format of the joint meeting will follow the pattern set by its predecessors.
It is intended to review hardware and architecture developments together
with languages and software tools for supporting parallel processing.
Another objective of the conference will be to highlight advances in
algorithms and applications software on vector and parallel architectures.
It is expected that the programme will cover languages/software tools,
hardware/architecture, algorithms/software and applications.
Also special sessions will be devoted to the field of application and/or
programming language specific architectures; i.e. machines, where
performance has been gained through limiting the field of applications, or
systems designed according to a joint optimization of programming language
and architecture.
Other topics of special interest are
* performance analysis for real-life applications
* testing and debugging of parallel systems
* portability of parallel programs
* paradigms for concurrency and their implementation
The conference should appeal to anyone with an interest in the design and
use of vector and parallel machines.
Call for Papers
Original papers are invited for the conference. Five copies of the full
paper (maximum of 10 pages) are to be submitted no later than Feb 1, 1990.
The proceedings of the joint VAPP/CONPAR conference will be published as a
volume in the Springer Lecture Notes in Computer Science series.

Subject: Moscow Domain Decomposition Conference
Call for papers for the
Fourth International Symposium
on Domain Decomposition Methods
for Partial Differential Equations
Moscow, USSR, May 21-25, 1990
Dear Colleague:
The Soviet Academy of Sciences has undertaken to organize the Fourth
International Symposium on Domain Decomposition Methods for Partial
Differential Equations. It will take place in Moscow, May 21-25, next year.
The three previous conferences in this series were quite successful. They
were held in Paris in January 1987, at UCLA in January 1988 and in Houston
in March of this year. The Paris conference was sponsored by SMAI and co-
sponsored by SIAM. The Houston conference was sponsored by SIAM and co-
sponsored by SMAI. As you probably know, the proceedings of the first three
conferences have been or are being published by SIAM. Proceedings are also
planned for the Moscow meeting--published in Russian by the Soviet Academy
of Science and in English by SIAM.
At the Houston conference there were extensive conversations on the Moscow
meeting, with active participation by the two Soviet participants, Yuri
Kuznetsov and Valeri Agoshkov, a representative of SIAM, and a number of
Western scientists. A program committee was formed, of which I am a member.
The program will focus almost exclusively on domain decomposition methods but
some talks on multigrid methods might also be scheduled. The preliminary plan
calls for thirteen invited speakers of which four will be from the Soviet
Union and nine from the West. In addition, there will be a number of shorter
contributions. A full day excursion is planned but there will also be four
full days of scientific activity. I have every expectation that most of the
leading contributors to the field will participate and that it will be a very
successful conference.
The Soviet scientists would like as wide an international participation as
possible, but they also stress it might not be possible to accommodate
everyone who has an interest in attending because of a shortage of hotels and
other facilities. Nevertheless, they and the program committee wish to
encourage all scientists to express their interest in participating by
submitting an abstract of a contributed talk. There is no fixed format, but
we recommend that the abstract be limited to 100 words and that it contain a
description of the problem, an explanation of why it is important, and how it
is solved. Prospective participants should also provide additional
information on previous research on domain decomposition methods and related
areas.
Please send your abstract and additional information no later than December
15, 1989 to:
Olof Widlund

E-Mail: siampubs@wharton.upenn.edu
Fax: (215) 386-7999
Telex: 446715
Members of the program committee will then contact the Soviet organizers
before the end of the year. We hope that it will be possible to notify all
interested parties relatively early next year whether they can be accommodated
and what the costs will be. All Western participants will have to cover at
least their air fare to Moscow from non-Soviet sources. While there will be
no conference fee, a number of participants will also have to cover at least
some of their living expenses in Moscow.
