THE HOUSEHOLDER SYMPOSIUM XI MEETING
ON NUMERICAL ALGEBRA
The Householder Symposium XI on numerical algebra will be held
during the week of June 18--22, 1990 at Tylosand, Halmstad on the west
coast of Sweden. This meeting is the eleventh in a series, previously called
the Gatlinburg Symposia. It has been agreed to rename all subsequent
Gatlinburg Symposia to honor Alston S. Householder, one of the pioneers
in Numerical Linear Algebra and organizer of the first four
Gatlinburg meetings. The meeting is an international conference of experts
in the field of Numerical Algebra. The format of the meeting is a sequence of
invited papers during the day and special workshops organized by the
participants in the evening. There is no formal program, but traditionally
a few topics are emphasized. For this meeting they will be large scale
nonsymmetric linear algebra problems, least squares, and matrix inertia
The meeting is being organized by the Householder committee, in cooperation
with the SIAM Activity Group on Linear Algebra.
Chairman of the committee for this meeting, and in charge of the
local organization is Ake Bjorck of Linkoping University, Sweden.
The traditional format of the Householder Symposia requires that
the attendence is limited. The organizing committee invites all qualified
persons to apply to attend. The application should consist of a vita and an
extended abstract (about two pages) of a paper you would present if invited to
speak. The latter will be used by the committee in planning the program.
Material should be sent before November 1, 1989 to

ILAS-NET Message No. 39
As many of you will know, the former International Matrix Group (IMG)
is now known as the International Linear Algebra Society.
Accordingly, IMG-NET will now be called ILAS-NET.
IMAGE #2 (January 1989) - produced by Bob Thompson and Jane Day-
has now been mailed to about 300 people who returned their coupons to
Bob. It may be a little time before it reaches people outside North
America - as it was mailed surface mail.
IMAGE #3 (hopefully out in July) will be edited by Bob Thompson and
Steve Leon. Please send you news to Steve Leon, whose e-mail address
The production and mailing costs of IMAGE are fairly considerable-and
we have found it necessary to institute a small membership fee for
ILAS to cover these and other necessary expenses. The fee will be
$12. Fees paid in 1989 will also cover 1990, though a voluntary
contribution of $12 to cover the second year will be greatly
appreciated. Thereafter the fee will be annual. We hope all those
interested in linear algebra will join ILAS. We realize that it may
be difficult for some members to pay the fee. We will therefore waive
it upon request. Mebmbers will receive IMAGE.
If you wish to Join ILAS, please send the following form and your
membership fee (or a letter) to James R. Weaver (ILAS' treasurer).

MULTIDIMENSIONAL HYPERBOLIC PROBLEMS AND COMPUTATIONS
April 3-14, 1989
Organizers: James Glimm and Andrew Majda
The field of multi dimensional conservation laws is
new and ready for development. The analytic techniques
of compensated compactness, the application of geometric
optics to multidimensional shock stability, deeper
understanding of nonlinear interactions have all
been developed in the last decade. There are emerging
also powerful scientific computation methods (and machines);
higher order methods, and the new generation of front tracking
schemes have produced dramatic pictures of complex flow
This two-week workshop, part of the IMA 1988-89 program on
NONLINEAR WAVES, will begin with introductory lectures on
the mathematical and computational developments. The Tuesday,
April 4, program will be devoted to forward looking lectures
based on the work of Ron DiPerna and delivered by his friends.
The second week will include lectures on numerical algorithms
and results, recent results on the Boltzmann equation and
other rarefied gas dynamics models which shed light on multi-
dimensional conservation laws, and recent theoretical and
asymptotic results on multidimensional problems and models
in continuum mechanics. There will be a session on open
problems. (There will also be contributed sessions;
those who wish to contribute should submit abstracts to
The April 10-11 portion of the program is
cosponsored by the Minnesota Supercomputer Institute.

Subject: Sweatshop on Computational Issues
COMPUTATIONAL ISSUES FOR NONLINEAR HYPERBOLIC WAVES
April 17-21, 1989
Organizers: James Glimm and Paul Woodward
The ``Sweatshop'' will act as a follow up to the IMA Workshop
on Multidimensional Hyperbolic Problems and Computations,
April 3-14, and will specifically focus on hyperbolic wave
theory as an aid to computation and the use of computation to
better understand hyperbolic wave theory. Rather than a lecture
format, there will be working sessions based on the computer
resources of the IMA and the Minnesota Supercomputer Center,
in particular the Cray II.
It is expected that the following topics will be included:
(a) Front tracking on Minnesota Supercomputer Center machines.
(b) Computational modeling of novel fluid problems, especially
using Riemann solvers and wave interaction concepts.
(c) Comparison of Godunov, front tracking, local mesh
refinement and hybrid methods.

NAS organization at NASA Ames operates a state-of-the-art
supercomputer center, with a 4-processor Cray-2, an 8-processor Cray
Y-MP, a nationwide high-speed communications network, and numerous
high-performance color graphics workstations. Recently NAS, in
conjunction with DARPA, augmented its facilities by acquiring a

floating-point hardware. Later this year a high-performance MIMD
research computer system will be added to this facility.
As a part of its research effort, the Applied Research Branch of NAS
is seeking additional personnel to take the lead in working with NASA
scientists to implement some important scientific applications on the
highly parallel computer systems. Qualifications for these positions
include the following:
An advanced degree in computer science, mathematics, physics, or
Programming experience on an advanced parallel or vector computer
system in a scientific application. Experience on a CM-2 or a MIMD
hypercube system is particularly desirable.
Published articles in parallel computing or numeric computation.
Familiarity with Fortran and the Unix operating system.
Familiarity with computational fluid dynamics or other similar
Expertise in parallel languages and programming environments.
U.S. citizenship is not required, but candidates must be at least
