Subject: Level 3 BLAS update notice

In April 1987 we published a proposal for a set of Level 3 BLAS.
Since then the proposal has been presented and discussed at various
meetings, comments have been received, and experience gained in using
the Level 3 BLAS to code block-structured algorithms in Linear Algebra.
As a result we have decided to make the a number of changes to the
original proposal.

To receive a hardcopy of the changes and of the revised report send a note to:

UNIVERSITY OF BATH, U.K.
SCHOOL OF MATHEMATICAL SCIENCES

LECTURESHIP IN COMPUTATIONAL APPLIED MATHEMATICS / NUMERICAL ANALYSIS

Applications are invited for the above post which is available from 1st.
September 1988 in the School of Mathematical Sciences. The present
appointment is being made in the Mathematics Group, which includes pure
and applied mathematics, control theory and numerical analysis.

It is expected that the successful candidate will be working in numerical
analysis or in some area of computational applied mathematics, which
should be interpreted broadly. Current research in numerical
analysis includes numerical methods for nonlinear and bifurcation
problems, and for boundary integral equations arising from partial
differential equations. Recently an interest in parallel algorithms has been
developing, in particular, their application in semiconductor device modelling.
Current research in applied mathematics includes numerical studies of
electromagnetic, acoustic and elastodynamic wave scattering, and bifurcation
phenomena associated with capillary-gravity waves. To support our activity
in these and other areas we have applied for funds to purchase a MEIKO
Computing Surface and related software which would provide us with a
transputer based parallel computing environment.

Only a person of proven research record or recognisable research potential
will be considered for this position. The new lecturer will be expected to
develop independent research and to play an active role in the research
activities in the School. At the beginning the teaching load will be
commensurate with age and experience. Salary scale is currently 9,260-19,310
UK pounds.

CERFACS
Recruitment of PhDs and post-docs.

The European Centre for Research and Training in Scientific
Computation (CERFACS) in Toulouse, France is continuing to expand.
A call for candidates to join CERFACS at or around September 1988
at either the post-doctorate or post-graduate level has just been
made. The PhD grant (initially for two years) is 8700 FFr net per
month, and the post-doctorate grant (annually renewable) is for
12000 FFr net per month. The cost of living in the Toulouse region
is fairly low and, depending on one's tastes, it should be
possible to live fairly well on these salaries.
As is usual in these announcements, there is not much time
before the deadline for receipt of applications. At least a
strong indication of interest should be made to CERFACS,
42 Ave G Coriolis, 31057 Toulouse Cedex, France.
(Tel +33-61-07-96-96, FAX +33-61-07-96-13, Telex 521888F) before
June 15th, preferably including a CV and an indication of the main
interests of the candidate. e-mail can also be sent to me (at
na.duff@score.stanford.edu) although I would prefer if you
simultaneously sent the same communication directly to CERFACS.
There are now four teams at CERFACS, the original ones in
parallel algorithm development and numerical computation,
instability and turbulence, and aerodynamic flows, and a new one in
visualization methods for computational fluid mechanics.
Currently the main machine in the Centre is an ETA-10P,
although there is good access to an IBM 3090/VF (currently 4
processor .. to be upgraded to six), a 4-processor CRAY-2, and a
CRAY X-MP. An Alliant FX/80 (8 processors) and a Gould NP1 (2
processors) will be installed at the Centre in June, and a
hypercube is planned for delivery in September/October.
There are also possibilities of funding visits from more
senior researchers. It is easiest if interested parties contact
me directly.

Subject: Toronto ODE Conference


Final Announcement for
The 1988 Conference on the Numerical Solution of IVPs for ODEs
to be held 20-24 June 1988 at the University of Toronto

Organized by
Professors Wayne Enright and Ken Jackson,
Department of Computer Science, University of Toronto,
Toronto, Ontario, Canada, M5S 1A4.
(enright@csri.toronto.edu or krj@csri.toronto.edu)


The Conference.

Currently we have scheduled five 50-minute invited lectures and
sixty-two 30-minute contributed talks at "The 1988 Conference on the
Numerical Solution of IVPs (Initial-Value Problems) for ODEs
(Ordinary Differential Equations)" to be held 20-24 June 1988 in the
Department of Computer Science at the University of Toronto. In
addition, there will be ample time for informal discussion with
colleagues at the meeting. The invited speakers are: J. C. Butcher,
P. Deuflhard, J. Dormand and P. J. Prince, C. W. Gear and
L. F. Shampine. (Regrettably, the other two invited speakers,
R. Jeltsch and S. P. Norsett, are not able to attend.) The
programme for the conference is listed below. Abstracts for all
talks will be distributed at the meeting.

In a preliminary conference announcement, we stated that no
other form of publication is planned for this meeting. However,
this has since changed. Speakers at the conference have the option
of submitting a paper on the topic of their talk to a special issue
of the SIAM Journal on Scientific and Statistical Computing. (Note
that it is not mandatory for speakers to contribute a paper to
SISSC.) Contributed papers will be refereed according to the usual
SIAM procedures, although we will attempt to expedite the review
process. To submit a paper for the special issue, give your
manuscript to one of the conference organizers at the meeting. The
deadline for submitting a manuscript is 24 June 1988, the last day
of the conference.

To facilitate travel arrangements, the conference will close at
noon of the final day. The language of the conference will be
English.

There will be several other large conferences in Toronto --
including the Economic Summit -- at the same time as our meeting.
Therefore, if you have not already reserved accommodation for the
conference, we recommend that you do so as soon as possible to avoid
disappointment.

The final date for submitting a paper to the conference has
long past. However, if you wish to attend the conference but have
not yet registered, please print, complete and mail to one of the
conference organizers (by regular post -- NOT E-MAIL) the conference
registration form below along with your registration fee.
Alternatively, you may register at the conference. Also included
below is a form to reserve residence accommodation at Whitney Hall
-- please print, complete and mail this together with your deposit
directly to Whitney Hall -- NOT to the conference organizers.
Alternatively, instructions for reserving a room at The Delta
Chelsea Inn are provided below.


The Conference Location.

The site of the conference is the University's downtown (St. George)
campus. All technical sessions will be held in the Sandford Fleming
Building (sometimes called the Sandford Fleming Laboratory),
10 King's College Rd., at the south end of the campus. The main
lecture room for the conference is SF1105 on the main floor, east
side of the Sandford Fleming Building. Those of you staying in
residence accommodation will be housed in Whitney Hall, 85 St.
George St., located about 100 meters north of the Sandford Fleming
Building. The Delta Chelsea Inn is about a kilometer east of the
Sandford Fleming Building at 33 Gerrard St. W. A map showing the
locations of all these buildings is available upon request.


Toronto.

Those of you who have not been in Toronto recently will notice many
exciting changes. The cosmopolitan flavour of the city is reflected
in the thriving Chinese, Italian, Greek and West Indian communities,
to mention only a few. The city has an excellent reputation for
fine international cuisine. There is a wide variety of restaurants
suiting every taste and pocketbook, from elegant dining rooms to
fast-food deli counters. For avid walkers, there are many pleasant
strolls around the campus and the numerous parks and gardens nearby
in the city. Sites worth seeing include the Royal Ontario Museum,
the McLaughlin Planetarium, the Gardiner Museum of Ceramic Art (all
on the east side of the University campus), the Art Gallery of
Ontario (a few blocks south of the campus), Harbourfront and Ontario
Place (both on the lakeshore), The Science Centre (a few kilometers
north-east of the campus), as well as the McMichael Canadian
Collection (art of "The Group of Seven") and the internationally
acclaimed Metropolitan Toronto Zoo (both on the outskirts of
Metropolitan Toronto). And of course, there are many shops and
boutiques close to the University campus. In addition, Niagara
Falls is about 130 km south-west of Toronto; the Shaw Festival
Theatre is located a short drive from the Falls in the historic and
picturesque town of Niagara-On-The-Lake; and the Shakespearean
Festival Theatre is located in Stratford, Ontario, about 150 km west
of Toronto. More information about the city and the surrounding
areas will be included in your conference registration package.

The average high for Toronto in mid June is about 25C (78F),
the average low about 15C (59F), with inclement weather being
uncommon. However, the temperature is quite variable at this time
of year, and may be considerably warmer or cooler than these
averages suggest.


On-Site Registration.

The on-site registration for the meeting will take place in the
Atrium outside room SF1105 on the main floor, east side of the
Sandford Fleming Building on Sunday, June 19, from 19:30 to 21:00,
Monday, June 20, from 8:15 to 9:00, and every other morning of the
conference from 8:30 to 9:00. In addition to registration on the
Sunday evening, there will be an informal gathering with light
refreshments for conference participants and their guests in the
Atrium of the Sandford Fleming Building.

If you have registered for the conference, but are not able to
come, please inform us of this -- particularly if you have submitted
a paper -- so that we can remove your name from the programme. We
will refund your conference registration fee if informed before
June 10 of your inability to attend the conference. Contact Whitney
Hall or the Delta Chelsea Inn directly for a refund of your room
deposit.


Transportation.

Both the University campus and the Delta Chelsea Inn are about a
half-hour drive from the Lester B. Pearson International Airport.
Taxi or Airport-Limousine fare to either is about $25-30 (Cdn),
independent of the number of passengers in the vehicle.
Alternatively, there is frequent bus service (every 20 minutes from
5:25 to 22:45) from the airport to the downtown hotels, including
the Delta Chelsea Inn. The cost per person is $7.50 (Cdn) one-way
or $12.50 (Cdn) return.

Unfortunately, there is no direct bus service between the
airport and the University campus. You could, though,

o+ take the airport bus to the the Delta Chelsea Inn,

o+ walk a block north from the Inn to College Street,

o+ walk or take the street-car west about a kilometer to St. George
St.,

o+ and then walk about 100 meters north on St. George St. to Whitney
Hall.

Alternatively, you could

o+ take an airport bus to the Islington Subway Station,

o+ take the subway east to the St. George Subway Station,

o+ and then walk about 200 meters south on St. George St. to Whitney
Hall.

The second alternative is cheaper -- $4.00 (Cdn) one-way or $6.50
return for the airport bus; both the subway and the streetcar cost
$1.05 (Cdn) for a single ride or eight tickets or tokens (each good
for one ride) for $7 (Cdn). However, the bus service to the
Islington Subway Station is less frequent -- about every 40 minutes
from 7:00 to 00:30. By the way, there are 24-hour money exchanges
in the Toronto airport; I believe they offer competitive rates.

Please circulate this announcement to interested colleagues.

Subject: request for info

I am interested in computer codes that do the equivalent of a
triangulation in more than three variables. For example, given
a collection of points in R**3, find a collection of tetrahedra
that have the points as vertices and that tessellate the convex
hull of the points.

Any information would be appreciated.
