I have enjoyed my many professional and personal contacts with the
members of na-net. I shall be devoting the first few months of
retirement to getting my ATT 3B1 (or UNIX-PC) up to functioning as a
node connecting to a mail and news feed and hope to be on the network
by this summer.
The final volume of ARO sponsored workshops which I ran, the one on
Medium Scale Multiprocessors should appear this spring.

SUBJECT: Ilas Inaugural Conference
On behalf of the International Linear Algebra Society (ILAS,
formerly IMG), we invite you to participate in the Society's
Inaugural Conference to be held August 12-15, 1989, at Brigham Young
University in Provo, Utah, USA. This will be a general international
meeting open to all with an interest in matrix theory. There will be
special concentration on nonnegative matrices and related topics.
Accommodation is available for up to 5 nights (Aug. 11/12 through
15/16) in on-campus dormitories and a meal plan is available in an
on-campus cafeteria on Aug. 12,14,15 (the meal plan includes no meals
on Sunday). The joint cost of accommodation and meals is $74.90
double occupancy (you may wish to select your roommate).
Alternatively accommodation and meals may be purchased separately.
The cost of a dormitory room is $10 per night double occupancy. For
those wishing to stay off campus, the 3-day meal package is $31.20,
or for the same package excluding breakfast $23.25. Single meals may
also be purchased at the cafeteria.
Dormitory space is limited and will be assigned in the order that
requests are received once invited speakers have been accomodated. If
you would prefer single occupancy, you may so indicate on the housing
form. Requests for single occupancy will be granted later if space
is available.
On-campus accomodation and meals are of high quality for an
academic institution. Please note that some regulations of religious
origin govern residence in BYU dormitories, such as prohibition of
alcoholic beverages and smoking. Coffee or tea are not served on
campus.
Lodging and meals are availbale off-campus within walking
distance. Please indicate on the registration form if you would like
information on off-campus housing.
There will be no registration fee. An optional luncheon buffet
(cost $15) and informal Sunday afternoon mountain outing are
scheduled for August 13 at a local resort.
Provo is located about 50 miles south of Salt Lake City. Salt Lake
International Airport is well serviced by most major US airlines, and
reasonably priced limousine service is readily available to and from
Provo (information will be sent to those who register). Salt Lake
City is also serviced by Amtrak. Within easy driving distance from
Provo (less than one day) lie many of the spectacular attractions of
the Rocky Mountain West.
We wish to encourage contributed 15-20 minute talks, subject to
the unavoidable limitations of space and time. Please let us know if
you wish to give such a talk. We shall also have some invited 30-40
minute talks. More details on the program will be available at a
later stage.
A special issue of Linear Algebra and its Applications will be
devoted to the meeting. This issue will contain only papers that meet
the publication standards of the journal, and that will be approved
by normal refereeing procedure. Papers should be submitted in
triplicate by November 1989 to one of the special editors of this
issue, who are Wayne Barrett, Daniel Hershkowitz, and Donald
Robinson.
We would appreciate it if you could let us know by April 30 if you
are planning to participate. Please return the enclosed registration
form to James R. Weaver (ILAS treasurer), and the enclosed
housing/mealplan form to the Office of General Services at Brigham
Young University. If you need further information, please contact
Wayne Barrett (mailing address on registration form, or email
address: barrettw@byuvax.bitnet).
We very much hope that you can participate in this Inaugural
Conference, as you presence will help to make it a success. We shall
try to make it worthwhile and enjoyable for you and look forward to
seeing you there.
We also invite you to become a member of the International Linear
Algebra Society. The annual membership fee is $12. However, as we
recognize that some potential members may have difficulties in paying
the fee, we shall gladly waive it upon request. Dues paid in 1989
also cover 1990, though a voluntary contribution of $12 to cover the
second year will be greatly appreciated. Thereafter the fee will be
annual. Note that you may attend the meeting without joining ILAS,
and we hope you will join ILAS even if you cannot attend the meeting.
You can use the enclosed conference form to indicate your intentions.

Subject: Argonne Wilkinson Fellow Named
EWERBRING NAMED AS WILKINSON FELLOW IN COMPUTATIONAL MATHEMATICS
L. Magnus Ewerbring of Cornell University has been named the 1989-90
Wilkinson Fellow in Computational Mathematics. The fellowship is awarded
by the Mathematics and Computer Science Division at Argonne National Laboratory
to a young scientist actively engaged in computational mathematics and parallel
computing research. Ewerbring will join the Mathematics and Computer Science
Division for a one-year term beginning in September 1989.
Ewerbring will receive a Ph.D. degree from Cornell University in August 1989.
For his thesis, he has derived generalizations of the singular value
decomposition that have important applications in canonical correlations and
are well suited for parallel machines. In addition to conducting his doctoral
research, he has worked at Thinking Machines Corp. developing code for linear
algebra routines on the massively parallel Connection Machine. As part of his
research there, Ewerbring devised techniques for ensuring that data are
efficiently mapped onto processors, realizing a savings in computation time of
up to 33 percent.
Currently, Ewerbring is a Graduate Fellow of the Mathematical Sciences
Institute at Cornell University.
The Wilkinson Fellowship was created by Argonne's Mathematics and Computer
Science Division in memory of Dr. James Hardy Wilkinson, F.R.S., who for
many years acted as a consultant and guiding spirit for such efforts as the
EISPACK and LINPACK projects. The fellowship is intended to assist a young
scientist who is actively engaged in state-of-the-art research in computational
mathematics, numerical linear algebra, and parallel computing.
Further information about the fellowship can be obtained from Jack Dongarra;

Subject: Fifth Parallel Circus
FIFTH PARALLEL CIRCUS
Rensselaer Polytechnic Institute, Troy, NY, April 28-29, 1989
THEME: Parallel Numerical Algorithms, Programming Tools and Applications.
OBJECTIVE: The meeting is an informal gathering of researchers interested
in parallel processing. The intention is to discuss recent results in the
area and exchange ideas for future work. The atmosphere is casual. The
speakers are chosen at the beginning of the circus. To encourage discussion,
there are no formal proceedings. We expect that about 60 people will be
in attendance and therefore no parallel sessions are planned.
HISTORY: The circus has been held twice a year for two days duration, on
Fridays and Saturdays. The first Parallel Circus was held in May 1987 at
Yale University (chaired by Prof. M. Shultz), the second at Cornell University
in November 1987, (chaired by Prof. Van Loan), the third was organized
by V. Sonnad at IBM Kingston (chaired by Prof. G. Golub and M. Schultz),
and the fourth was held at Rutgers University in December 1988 (chaired by
Prof. G. Golub and Prof. A. Gerasoulis).
PLACE: The Fifth Parallel Circus is being organized by Rensselaer Polytechnic
Institute and will be held on the Rensselaer campus, Troy, New York
(chaired by G. Golub and M.Schulz and organized by Joseph Flaherty and Bolek
Szymanski). Troy is part of tri-city area of Albany-Schenectady-Troy located
at the center of New York State. It is easily accessible via plane (Albany
airport), train and automobile.

UNI-C, DTH and The Danish Research Academy are pleased to announce the
1989 Summer School in applied numerical methods on parallel and vector
type computers. The summer school is financially supported by The
Danish Research Academy and the DP Capacity Board of The Danish Min-
istry for Education.
The school comprises six series of classes within chemical simulation,
quantum chemical calculations of electron orbits, seismic methods and
general numerical algorithms for vector and parallel computers. The
lectures will be given by international recognized researchers, and
provide an inspiring insight into the prospects and challenges of com-
puter applications of modern numerical methods.
Application workshops on afternoons and evenings include tutorials in
using UNI-C's computers, an Amdahl VP1100 vectorprocessor w/ 128 Mbyte
central memory and an Alliant FX/8. In addition there is an Intel
Hypercube, kindly lent by the Department of Computer Science at The
University of Copenhagen, and an Ardent Titan graphical supermini,
which is placed at our disposal from High Tech Systems, Ballerup.
Participants are requested to bring their own FORTRAN programs for the
exercises, and use this opportunity to install and optimize their ap-
plication program on one or more parallel type computers, guided and
instructed by the guest lecturers and UNI-C staff.
UNI-C is situated on the Technical University of Denmark campus in
Lyngby, a northern suburb of Copenhagen, 12 km from Central Copenhagen.
UNI-C was established by a merger of three major University Computing
Centres, Copenhagen, Aarhus and Lyngby to form one supercomputer centre
for Denmark. Besides the Amdahl VP1100 with 30 Gbytes of disk storage,
UNI-C has an IBM 3081, a UNISYS 1100/92, a CDC Cyber, an Alliant FX/8
and several VAX'es.
Guest professors:
Dr. Jeremy du Croz (JC)
N.A.G. Ltd.
Dr. du Croz will talk on how to provide efficient portable numerical
software for supercomputers. Particular topics include level 2 and 3
BLAS, applications in linear algebra and nonlinear problems, the
LAPACK project, FFT's, quadrature and random number generators.
Dr. Iain Duff (ID)
AERE, Harwell and CERFACS, France.
Dr. Duff will talk on the solution of large sparse systems of linear
equations, structure and factorisation.
Dr. David Fincham (DF)
University of Keele.
Dr. Fincham will talk on numerical methods in chemical modeling and
simulation.
Dr. Bengt Fornberg (BF)
Exxon Research and Engineering Company.
Dr. Fornberg will talk on seismic modeling with special emphasis on
pseudospectral methods.
Dr. Michael T. Heath (MTH)
Oak Ridge National Laboratory, Tennessee, USA
Dr. Heath will talk on algorithms for (massively) parallel computers.
Dr. V.R. Saunders (VS)
SERC, Daresbury, England.
Dr. Saunders will give lectures on numerical methods in quantum chem-
ical calculations.
Workshops and tutorials in using the various summer-school computers
will be headed by UNI-C staff.
Enrollment:
The summer school is open to Danish, Nordic and International post
graduate students. Applications from other students, post doctoral
students and researchers are welcome, and applicants will be selected
from those who are actively working on projects that are appropriate
for parallel and vector type computing. Enrollment is limited to 40
participants. We expect 20 Danish, 10 Nordic and 10 delegates from the
international research community.
The registration fee is DKR 3000, and covers lunch and lodging at near-
by student recidence. Participants wishing to stay at more luxury or
tourist hotels must pay their own accomodation expenses. The partici-
pants may apply for funding of traveling and lodging expenses. The sum-
mer school is free of charge for Danish and Nordic participants.
Persons attending the summer school will be expected to have some expe-
rience in scientific and numerical modeling on computers. Preferably,
they should bring FORTRAN code which represents work in progress. The
UNI-C staff will provide assistance in migrating code and data to the
summer school computers. The participants are expected to improve this
code during the workshop sessions assisted by guest professors, UNI-C
staff and co-participants.
