Subject: 1988 Conference on the Numerical Solution of IVPs for ODEs.
Preliminary Announcement for
The 1988 Conference on
The Numerical Solution of IVPs for ODEs
20-24 June 1988
Organized by
Professors W. H. Enright and K. R. Jackson,
Department of Computer Science, University of Toronto,
Toronto, Ontario, Canada, M5S 1A4.
(enright@csri.toronto.edu or krj@csri.toronto.edu)
This is a preliminary announcement for The 1988 Conference on
the Numerical Solution of Initial-Value Problems for Ordinary
Differential Equations to be held in the Department of Computer
Science at the University of Toronto, 20-24 June 1988. (To
facilitate travel arrangements, the conference will close at noon of
the final day.) The language of the conference will be English.
The previous conference in this series was held in Albuquerque
in July of 1986, and its programme included talks on both Initial-
Value Problems (IVPs) and Boundary-Value Problems (BVPs) for
Ordinary Differential Equations (ODEs). Because of the large number
of researchers working in these two areas and the modest number of
them active in both fields, we chose to emphasize IVPs at the
Toronto meeting, although talks related to BVPs with a significant
IVP content will not be excluded.
The following distinguished researchers have agreed to present
50-minute invited lectures at the Toronto meeting: J. C. Butcher,
P. Deuflhard, J. Dormand and P. J. Prince, C. W. Gear, R. Jeltsch,
S. P. Norsett, and L. F. Shampine. In addition, we are still
waiting to receive acceptances from a few other invited speakers.
We hope to attain a balance between the practical and
theoretical aspects associated with the numerical solution of IVPs
for ODEs in the talks at this conference. In part, the invited
speakers were chosen with this in mind. In addition, since there
are so many distinguished researchers working in this field, we
decided to avoid an overlap between the invited speakers at the
Toronto meeting and those who gave ``highlighted'' talks at the 1986
ODE Conference in Albuquerque.
Titles and abstracts for 30-minute contributed talks will be
solicited in the next conference announcement to be distributed
early in 1988. To enable us to inform authors by 1 May 1988 whether
their paper has been accepted for presentation at the conference,
the deadline for receiving titles and abstracts will be 18 March
1988. However, if you require an early acceptance for your talk,
mail its title, names of authors, their institutions, and a single-
spaced typed abstract of at most 200 words to us and we may be able
to give you an early acceptance. The collection of titles and
abstracts for all accepted talks will be published as a technical
report to be distributed to participants at the conference. No
proceedings or special issue of a journal for this meeting is
planned.
We hope to keep the cost of attending this conference to a
minimum. By holding the meeting on the university campus, we hope
to keep the conference registration fee below $100, with a possible
further reduction for students. Also, we have reserved a block of
reasonably-priced rooms at one of the college residences, but, to
accommodate those participants who prefer less Spartan quarters, we
have also reserved a block of rooms in a nearby hotel. Details
concerning the conference registration and accommodation reservation
will be given in our next conference announcement.
We hope that there will be some funds available to defray the
expenses of those with no other means of travel support. If we are
successful in obtaining such funds, guidelines for applying for
travel assistance will be contained in our next conference
announcement also.
If you did not received an announcement similar to this one by
regular post and you are interested in attending the 1988 Toronto
ODE Conference, please send your name and address (regular and, if
possible, electronic) to either one of the conference organizers at
the address above.

Subject: CERFACS -- European Centre for Supercomputing
CERFACS
I am happy to report that the European Centre for Supercomputing
based in Toulouse, France (CERFACS) is now a reality. It was
established in February as an organization and was officially
inaugurated as a centre on October 9th, 1987.
As was conceived at the outset, CERFACS has twin aims of research
in supercomputing and parallel computing and applications on such
architectures, and advanced training in aspects of the same. The
Centre is not planning to design machines, nor does it exist to
provide the services of a computer bureau. Its twin aims of research
and training will be conducted through projects in a multidisciplinary
environment.
There are currently three projects underway in the Centre. They are
on "Parallel algorithms" (project leader Iain Duff), "Real flows"
(project leaders Arthur Rizzi and Hieu Ha Minh), "Instabilities and
Turbulence (project leader Maurice Meneguzzi). Each project has
around 5-6 people, comprising senior research workers, post-docs, and
graduate students. It is planned to start more projects (up to around
ten) as funding permits.
By the beginning of 1988, the equipment will include a biprocessor
ETA Piper supercomputer, a MATRA X-MS 7020 (Encore Multimax),several
IBM PCs, Macintoshes, SUNs, and high-speed links to a wide range of
supercompouters including a CRAY-2, CRAY X-MP, CYBER 205, IBM 3090/VF,
FACOM VP 100, SCS 40, CONVEX, and SEQUENT. A hypercube based machine
will also be installed early in 1988.
It is planned to encourage visits by prominnent reseach workers
both of a short or long duration and some funding has been allocated
for this purpose. In addition, CERFACS will hold "Training Cycles"
which are conferences consisting principally of invited presentations
designed partly as training for CERFACS participants and also as a
regular conference for discussion of current research. The next will
be on "Sparse Matrrices" in April (12-14) and I will shortly circulate
a draft programme for this meeting which is open to anyone to attend.
As you might expect, the parallel algorithm group's main interest
lies in sparse matrix research. Currently I am spoending about one
week a month at Toulouse but am still principally based at Harwell
where our numerical analysis group is expanding and is still very
active.

Subject: Corrected Announcement of the L. Fox Prize
Third L. Fox Prize
[Ed. Note: This is a reposting of the announcement from
a previous digest, with transatlantic transmission errors
corrected.]
If you will be under 31 years old on January 1st 1988
and have not already won a first Fox prize, why not enter
for the 1988 competition? If you have such a student,
please encourage him or her to enter.
Calls for entries have already been published, but in
case you missed them, here are the rules.
Each entry should consist of three copies of a paper,
describing some of the candidate's research, that is
suitable for a 40 minute lecture at a numerical analysis
symposium. Whether or not the work has been published or
accepted for publication is irrelevant, but no person may
submit more than one paper. Unsuccessful candidates from
previous competitions are encouraged to enter.
The entries will be considered by an Adjudicating
Committee, its members being J.K. Reid (Harwell Laboratory),
K.W. Morton (Oxford University) and J.C. Mason (Shrivenham).
Particular attention will be given to the originality and
quality of each paper, and to the suitability of the
material for a 40 minute talk to a general audience of
numerical analysts. About 5 papers will be selected by the
Committee for presentation at a symposium that will be held
at Imperial College, London on Monday March 28th 1988. Only
the papers that are presented at the symposium will be
eligible for awards, but, subject to this restriction, the
Adjudicating Committee may award any number of first and
secondary prizes.
Entries should reach Dr. J.K. Reid (Computer Science
and Systems Division, Building 8.9, Harwell Laboratory,
Oxon OX11 ORA, England), not later than December 1st 1987.
Each candidate should include a statement that his or her
year of birth is not earlier than 1957, and should indicate
whether he or she would be available to present his or her
paper at the symposium. The Adjudicating Committee may
allow a deputy to present a paper in a case of exceptional
merit. The receipt of all entries will be acknowledged.
It is unlikely that travel funds will be available to assist
candidates who attend the symposium. Any questions should
be addressed to a member of the Adjudicating Committee.

Subject: Wanted: BFGS routine with Cholesky updates
To: na@score.stanford.edu
I am looking for a quasi-Newton subroutine which uses the BFGS update
and maintains a Cholesky decomposition of the second order information
and handles nondefiniteness in a reasonable way. If possible, I would
like code that can be distributed freely.
Thanks,

Subject: Gordon Bell Award
The Gordon Bell Awards Guidelines for Judges
Beginning in 1988, two $1000 awards will be given each year for 10
years to the person or team that demonstrates the greatest speedup on a
multiple-instruction, multiple-data parallel processor.
One award is for the most speedup on a general-purpose
(multiple-application) MIMD, the other for most speedup on a
special-purpose (single-application) MIMD. Speedup can be accomplished
by hardware or software improvements, or by a combination of the two.
The awards are intended to recognize the best, operational scientific
or engineering program with the most speedup, not including
vectorization on a vector processor.
Speedup is measured against a similar program run sequentially on one
processor of the same system. To be considered for the award,
submitted programs must have a factor of two more speedup than a
previous winning program.
The program should run at near the peak speed of any computer available
(including various supercomputers) and be a genuine, cost-effective
solution; "toy" programs will not be considered.
Hardware simulations are not permitted. The speedup must be
demonstrated on a running piece of hardware.
Definitions
Speedup:
The time taken to run an application on one processor using
the best sequential algorithm divided by the time to run the same
application on n processors using the best parallel algorithm.
General-purpose:
The parallel system should be able to run a wide variety of
applications. For the purposes of this test, the machine must run
three different programs that demonstrate its ability to solve
different problems. Suggestions are a large, dynamic structures
calculation; a transsonic fluid flow past a complex barrier; and a
large problem in econometric modeling.
Operational:
A program used to produce a useful scientific or engineering result.
Application:
The problems run for this test must be complete applications; no
computational kernels are allowed. They must contain all input, data
transfers from host to parallel processors, and all output. The
problems chosen should be the kind of job that a working scientist or
engineer would submit as a batch job to a large supercomputer.
Judging and Deadlines
Contestants must submit documentation of their base system and their
speedup by Dec. 1, 1987. Documentation should be in the form of
verified timings, description of the application, and any other support
data. Whether or not the application qualifies and verification of the
results will be determined by the panel of judges.
Judges will be selected by IEEE Software Editor-in-Chief Ted Lewis.
Winners will be announced in the March issue of IEEE Software. Winners
will be notified in advance and may be asked to submit a short summary
of their program for publication.
Send contest submissions to: Ted Lewis, Editor-in-Chief, IEEE
Software, c/o Computer Science Dept., Oregon State University,
Corvallis, OR 97331.
The judges for the 1988 awards are Alan Karp (chairman) of IBM
Research, Jack Dongarra of Argonne National Laboratories, and Ken
Kennedy of Rice University.
