Subject: Re: Fortran, C++ or Something Else?
Baker Kearfott sent in a collection of responses to his query last
week about programming languages for teaching numerical analysis
and mathematical software. Judging from the number of respones,
there is quite a bit of interest in this topic. But it was not
clear that all the authors of responses intended their remarks for
general consumption. So, let's hold off another week and invite
anyone interested in responding for the NA News to send their comments
to Kerfott, firstname.lastname@example.org, or to directly to email@example.com.
The responses in Baker's collection were from David Goldberg, Layne
Watson, George Corliss, Louis Howell, Bill Behrman, Paul Frederickson,
David Gay, David Hough, Cleve Moler and "Mike".

Subject: Machine-readable Bibliography Data Bases
With the help of the GNU awk utility, I recently converted
ACM Transactions on Mathematical Software (TOMS) algorithm
620 (References and Keywords for Collected Algorithms of the
ACM) to BibTeX format, with corrections, additions of
accents in names, and math mode sequences. This covers only
the 137 algorithms published in TOMS (one is from TOPLAS)
between June 1975 and June 1985 (I added the last year myself,
but ran out of steam in keeping it up-to-date); ordinary
papers in TOMS are NOT covered.
I would like to extend this work to cover the full contents
of TOMS, and other journals in numerical analysis and
computer science. Since this kind of work should only need
to be done once, the collections would naturally be made
FREELY AVAILABLE via standard electronic channels, including
I have software that can convert from UNIX bib/refer or
Bibix formats to BibTeX format. Tib is fairly close to
bib/refer, and Scribe format was the basis of the BibTeX
format design. Thus, collections in other formats can very
likely be massaged, largely automatically, into a consistent
BibTeX form, and with the help of a modest amount of awk
programming, back into other formats as required.
So, do any of you have bibliography data base files covering
journals in the cited areas that you would be willing to
share with the community? And perhaps those of you who are
journal editors can lean on the publishers to make, and keep
up-to-date, machine-readable copies of journal contents
which can be made freely available electronically.
Please correspond with me directly, and I'll summarize
results to this list. I will be out of the country for the
rest of May, so you won't get a response back from me until

Subject: Character Arguments in the BLAS.
I have been lately trying to write a program in C that calls the
Fortran level 1, 2, and 3 BLAS that I obtained from netlib.
After reading the reports that go with the level 2 and 3 BLAS, I am
not convinced that the character argument is the best way of passing
information about the job to be performed by a subroutine.
My main objection is due to the fact that different "other language"
compilers, such as C, handle character strings passed to and from Fortran
Thus, the main issue of portability of BLAS is jeopardized by
the practice of passing the character strings. Actually, from reading
the reports, it is obvious that the authors ran into this issue even for
Fortran compilers, since case of characters is a factor for some compilers.
In view of this, and lacking an agreement on how different languages
should interact, I do think that going back to the more portable
practice of passing integers corresponding to JOB information
(as is currently done in LINPACK) is the better way to go.

Subject: Eigenvalues of Elliptic Systems
Does anyone know of software to determine the eigenvalues LAMDA of
a pair of coupled elliptic equations of the form:
D LAPLACIAN(U) + (K - LAMDA I)U = 0
where U = (u1,u2), the Laplacian is in two variables, D is a diagonal matrix,
and K is not a diagonal matrix. The first component of U, u1, satisfies
homogeneous Dirichlet boundary conditions while the second component, u2,
satisfies homogeneous Neumann conditions.
I am asking this question on behalf of my colleague Hans Othmer, so
please address replies to email@example.com.

Subject: Course on MODULEF Finite Element Library
Pennsylvania State University
July 16-20, 1989
Club MODULEF was created in 1974 to bring together researchers
from academics, government, and industry interested in developing
a finite element program library with the following features:
o access to source code, enabling users to add and modify
o modular organization
o rapid incorporation of current theoretical developments
At present the club has about 250 institutional members from around the
world. The MODULEF library presently contains over 300,000 lines of
FORTRAN code and is being expanded continually. Though based in
France, at the Institut National de Recherche en Informatique et en
Automatique (I.N.R.I.A.), there is presently a major effort to make all
the documentation available in English.
Courses in the use of MODULEF have been offered regularly in France.
Because of the increasing American membership in Club MODULEF, such a
course is being offered for the first time in the United States. The
aim of the course is to introduce new users to the MODULEF library and
teach them both to use existing modules and to incorporate new modules.
I. Using existing modules
o A sample physical problem
- variational formulation
- approximation by finite elements
- steps in the implementation
o The MODULEF library
- organization of the library
- principle modules
- interactive use
- writing a calling program
o Examples and hands-on use
II. Creating new modules
We will explain how to create new modules to
be used with existing modules in order to
expand the capability of the library
PLACE AND TIME
The course will be held at the Pennsylvania State University in
University Park, Pennsylvania. It will run from Monday to Friday,
July 16-20, 1990.
Tuition is $200 for full-time academic participants and $500 for
industrial participants. Tuition includes a copy of "MODULEF: A
Modular Library of Finite Elements", a 350 page tutorial and reference
on MODULEF. THE COURSE WILL BE STRICTLY LIMITED TO THE FIRST 20
PARTICIPANTS TO REGISTER. Tuition must be paid at the time of
DOUGLAS ARNOLD. Professor Arnold is a leading researcher in numerical
analysis and differential equations at the Pennsylvania State
University and is a user and contributor to the MODULEF library.
MICHEL BERNADOU. Professor Bernadou is a leading researcher in
numerical analysis and computational shell theory and the director of
the MODULEF project at I.N.R.I.A.
PAUL LOUIS GEORGE. Dr. George is a full time researcher with the
Modulef project at I.N.R.I.A. He works on mesh generation techniques
and is the principal author of the extensive mesh generation facilities
in the MODULEF code.
MARINIA VIDRASCU. Dr. Vidrascu has been a full-time researcher with
the MODULEF project at I.N.R.I.A. since its inception and is the
largest single contributor to the design and coding of the MODULEF
library. She works in nonlinear elasticity.

The ICIAM 91 Program Committee invites you, as a potential organizer, to
submit a proposal for a minisymposium.
A minisymposium is a session of 3-5 speakers focusing on a single topic.
Sessions may be scheduled for two or three hours. The organizer of a
minisymposium invites the speakers and decides on the topics they are to
address. If you would like to organize a minisymposium, you must submit a
proposal on an ICIAM minisymposium form. Acceptance of proposals will be by
decision of the ICIAM 91 Program Committee.
Deadline date for minisymposium proposals: July 31, 1990
Contributed Presentations - Posters and Lectures
Participate in ICIAM 91 by submitting a paper, which you may present in
lecture or poster format. The ICIAM 91 Program Committee is encouraging
contributors to present their papers in poster form to increase communication
among participants, foster the development of international friendships, and
reduce the need for large numbers of parallel sessions.
Authors will have approximately 15 minutes for contributed presentations
(lecture format), with an additional 5 minutes for questions. Alternatively,
they may elect the poster format that encourages interactive discussions with
individuals interested in their work using flip charts and other visual aids.
If you desire to present a paper (lecture or poster format), you must submit a
summary not exceeding 100 words on an ICIAM 91 contributed paper/poster
presentation form or facsimile. You may also submit an abstract via e-mail.

2,000 guest rooms, 25 meeting rooms, an exercise room, a large outdoor
swimming pool, and many restaurants and lounge areas. It is located on the
city's "Metro" subway system which provides easy inexpensive access to most
points of interest.
The hotel, on 12 acres of a wooded park-like setting, is within walking
distance of the National Zoo, a few blocks from the National Cathedral,
Embassy Row, historic Georgetown and Rock Creek Park. The Sheraton Washington
boasts a multi-lingual staff fluent in a total of 20 languages, foreign
currency exchange services, telex facilities, and electrical adapters. A U.S.
post office is on the premises.
