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:

Subject:  JOB AT BATH, UK

              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
[email-masked]) 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.
              ([email-masked] or [email-masked])

     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.
