This brochure also contains information and forms for lodging and
registration and other miscellaneous items. (If you have recieved the
earlier form sent last fall, you should soon be getting this latest
one.) PLEASE pay special attention to the lodging information because
the rooms are quick to fill up. If you know others who are going, it
is best to get a deluxe condo that includes two bedrooms with two beds
each and a livingroom and kitchen with a hide-a-bed. They are generally
very nice and most economical, but they go the fastest.

Following is a list of the session times and speakers by last name. In
cases where we were unsure who the speaker will be, we simply list the
first one. Please consult the brochure for other authors and titles.
Updates to the brochure are:

Does anyone have Euler's constant, gamma, to at least 35 places,
with a reference for the source? A note about the method
of computation would also be appreciated, if available.

Thanks.

Subject: Numerical Algorithms Papers Database

Does anybody know if there exist an "ad-hoc" bibliographical database
containing information on all the published papers in the field of
numerical algorithms for vector and/or parallel computers (and related)?
I already know Inspec but, even if it contains a good amount of
information, the fields covered are too many and its use is quite
expensive.
Thank you in advance. Giuseppe Paruolo - CINECA

Subject: Fortran & Pascal for Scientific Computation

This is an advertisement for Fortran-SC and Pascal-SC. I am not
associated with the authors or distributors. I am a satisfied user;
if you try either of these products, you might like them too.

FORTRAN-SC is an extension of Fortran written at the University of
Karlsruhe for scientific computation. It is particularly suited for
the development of numerical algorithms which deliver high accuracy
and automatically verified results. The language allows the
declaration of functions with arbitrary result type, operator
overloading and definition, and dynamic arrays. Intervals are a
built-in data type. Fortran-SC runs on IBM 370 architecture
machines and uses the IBM program product ACRITH. Fortran-SC
functions as a pre-processor which makes it MUCH easier to program
ACRITH calls. Fortran-SC is available a low cost to ACRITH license
holders. Contact

PASCAL-SC is an extension of Pascal also written at the University
of Karlsruhe for scientific computation. It uses 12 digit decimal
floating point arithmetic and provides optimal arithmetic for many
higher numerical data types such as complex numbers, intervals, and
vectors or matrices over these spaces. Pascal-SC supports
user-defined operator overloading, giving it an Ada-like flavor. It
includes applications packages for linear systems, eigenvalues and
eigenvectors, evaluation and rootfinding for polynomials, and
accurate evaluation of rational expressions. Pascal-SC is available
for about $100 for MS-DOS machines and the Atari-ST. Contact

Subject: Wilkinson - SIAM Prize

The 1989 Wilkinson Prize in Numerical Analysis and Scientific
Computing is being awarded by SIAM to Paul Van Dooren of Philips in
Brussels. Paul's main contributions have been to the development and
analysis of algorithms for linear problems in systems theory. This is
a very vital and active area of research at this time. Wilkinson had
a high opinion of Paul; he was on his the reading committee and often
said only a few people realized the quality of this work. Paul was
subsequently awarded the Householder Prize.

Beyond Paul's research abilities is his lovely sense of humor and human
qualities. Congratulations, Paul!

The award will be given at the national SIAM meeting in San Diego.
Hope to see you there,

Gene Golub

Subject: FAX

Have you tried the FAX technology? I was in Europe a few months ago and
I needed by notes which were in Australia. The next day my own hand written
notes appeared before me and I was able to give my lecture!

I'm trying to collect FAX addresses and I have a few. If you have one, please
send it to me.

Subject: Kudos to Bill Gear

Here's kudos to Bill Gear who completed the job of President of SIAM in
December. (He's now officially Past-President.) In case you didn't notice,
SIAM seems to be as thriving as ever and much of that is due to Bill's
efforts. As his predecessor, I sat back with admiration in seeing him handle
the many complexities of the job with ease. Here's a quote from Margaret
Wright who is on the Council and observed Bill first hand.

"In addition to Bill's overall vision for and leadership of SIAM, his
remarkable skills in ``chairmanship'' have been evident at meetings of the
SIAM Council and Board. An a posteriori analysis of meetings chaired by Bill
reveals that he always manages to achieve stable and accurate
solutions, even to problems that might appear at first to be ill-posed!
The meetings are well organized, smoothly run and productive---never
meandering or regimented. Bill's equanimity and sense of humor
maintain a balanced and reasonable atmosphere, even in the midst of
disagreements among the participants."

Bill not only was Prez of SIAM but he was the chairman of his
department and managing editor of SISSC. (How did he do it?)

Thanks, Bill for all your efforts. We have all benefited.
I hope you carry on all your activities and research as successfully
as you have in the past.

Gene
