Subject: Precise Origin of Quote

Andrew Odlyzko is looking for the source of the following.
It may be from Gauss, father of scientific computing.
   "The lack of mathematical insight shows itself through
   nothing as clearly as through unbounded precision in
   mathematical calculations."
Can anyone help?

Subject: Exp Function Needed

I'm looking for an exponential function (e**X), good to 15 digits, that takes
the time/space trade as far toward time as possible. I need it fast, and
dont't really care how big it is. Is there anything available I could have??
    thanks,
      Paul

Objective:

NASA's Numerical Aerodynamic Simulation (NAS) Program, located at NASA
Ames Research Center near Mountain View, California, will be sponsoring
a conference on Scientific Applications of the Connection Machine from
September 12 to September 14, 1988. Focus of this conference will be the
application of the Connection Machine to the solution of large scale
computational problems in physics, in particular computational fluid
dynamics, chemistry, and engineering.


PROGRAM:

Monday, September 12


 9:00- 9:30	PARALLEL THINKING VS. SERIAL THINKING		Jim Bailey
		
		Data Parallel computing methods compute thousands of
		answers at once.  We have all been taught since elementary
		school to compute in ways that keep only one answer active
		at a time.  The difference between the two styles of
		computing, and example applications that fit well with
		each, are reviewed.

 9:30-10:15	THE CONNECTION MACHINE ARCHITECTURE		Jim Bailey
		
		The Connection Machine system is a data parallel
		computing system with 65,536 processors, a high-speed
		communications router, floating-point hardware, the
		DataVault mass storage system, high resolution display,
		front-end, and base systems software.  The role and 
		characteristics of each of these subsystems is introduced.

10:15-10:30	BREAK

10:30-10:45	DATA PARALLEL LANGUAGES:  GENERAL PRINCIPLES	Guy Steele

		There are several fundamentals of good data parallel
		programming practice that are independent of the 
		programming language used.  These overall fundamentals
		are introduced.

10:45-11:30	DATA PARALLEL LANGUAGES:  FORTRAN 8x		Guy Steele

		Fortran 8x is the first industry standard data parallel
		programming language.  The array extensions provide a
		direct way to compute on parallel data structures.  The
		data parallel extensions of Fortran 8x are reviewed.
		Familiarity with Fortran 77 is assumed.

11:30-12:15	DATA PARALLEL LANGUAGES:  C*			Guy Steele

		The pointer structure of C makes it an ideal base for 
		data parallel programming.  C* extends the language, in a 
		manner consistent with C++, to include parallel data
		structures.  The C* language is reviewed.  Familiarity
		with C is assumed.

12:15- 1:15	LUNCH

 1:15- 2:15	SCIENTIFIC COMPUTING:  BASE ALGORITHMS		Wati Taylor

		A variety of data movement and reduction primitives
		underlie efficient data parallel programs.  These 
		underlying operations are reviewed.  The role of the
		CM-2 Sequencer in optimizing the performance of these
		primitives is introduced.

 2:15- 3:15	SCIENTIFIC COMPUTING:  SOLVERS AND LATTICES	John Richardson

		Solvers and lattice-based algorithms (such as finite
		differences) are pervasive in scientific computing.
		Examples of these routines on the CM-2 are reviewed.

 3:15- 3:30	BREAK

 3:30- 4:00	DETAILED PROGRAMMING EXAMPLE:  WAVE SIMULATION	John Richardson

		The acoustic wave equation is a simple example of a 
		scientific simulation that operates on a lattice.  A simple
		two-dimensional finite difference solution, coded in 
		Fortran 8x, is introduced.  Modifications to implement
		fourth dimension in space, and to implement a 
		three-dimensional model are introduced.

 4:00-5:00	SCIENTIFIC VISUALIZATION ON THE CM-2		James Salem

		A graphics environment for real time visualization of
		the results of numerical simulations of Computational 
		Fluid Mechanics will be discussed.  Within this 
		environment the researcher may interactively perform
		real time flow visualization experiments.  Ideas for
		the future will be introduced.  Session will include
		demonstrations on the CM-2 by Jamie Sethian.

Conference Adjourns

OBJECTIVE:
This conference will be dedicated to providing an overview of the state of
the art in the use of iterative methods for solving sparse linear systems
with an eye to contributions of the past, present, and future.
The emphasis will be placed upon identifying current and future
research directions in the mainstream of modern scientific computing.
Recently, the use of iterative methods for solving linear systems
has experienced a resurgence of activity as scientists attack extremely
complicated three dimensional problems using vector and parallel
supercomputers.  Many research advances in the development of iterative 
methods for high-speed computers over the past forty years will be reviewed 
as well as focusing on current research.

ORGANIZATION:
The conference is organized by D. Kincaid, L. Hayes, G. Carey and W. Cheney, 
who are members of the host organization --- the Center for Numerical Analysis
(CNA) of The University of Texas at Austin.  This meeting is being

Many major airlines fly into Austin via Dallas or Houston with some
direct flights from other locations.  The primary air-carriers serving Austin 
are American, American-West, Continental, Delta, Northwest, Pan Am,
Southwest, TWA, United, and USAir.  Since airlines give discount rates for 
those staying over a Saturday night, plan to stay and enjoy the weekend 
in Austin!  An information desk operated by the City of Austin is located
in the airport and is a good source for free material on events and 
sights of interest in and around Austin.  (Just ask for a packet of 
information.)

TRANSPORTATION:
A hotel courtesy-van is available for transportation between the 
airport and the hotel (a short 15 minute trip).
[Regular hours of operation are on the hour and half-hour from
6:00a-12:00n and by request 12:00n-12:00m with frequent trips
Tuesday evening before the conference and Friday evening after
the conference.]  The hotel also operates a free shuttle bus to 
The University of Texas at Austin which is ten blocks north.
The City operates the ``catch a'dillo bus'' (short for armadillo) 
for transportation around the downtown area.

TENNIS DOUBLES-MIXER:
On Wednesday evening, a tennis doubles-mixer will be arranged.
So bring your tennis gear!

POINTS OF INTEREST:
Austin is the capitol of Texas with several points of interest
including the State Capitol Building, Governor's Mansion, Lyndon B.
Johnson Presidential Library and Museum, Zilker Park and Barton
Springs (spring-fed natural swimming pool always 68 degrees, and many
more.  Near to Austin are several scenic lakes, such as Lake Travis,
and the ``Texas hill country.''  Austin is in the center of Texas with 
historic San Antonio and the  Alamo only 70 miles  south, 
Dallas/Ft. Worth 200 miles north, and Houston 200 miles Southeast.
The weather is usually quite pleasant in Austin in October

                    BERGEN SCIENTIFIC CENTRE
                   PETROLEUM COMPETENCE GROUP


The mission of the Bergen Scientific Centre has been expanded to
include a  Petroleum  Competence  Group (PCG) which  will  be  the
European  Focal  Point  for the  Technical  Computing  activities
characteristic of the petroleum industry.

The group concentrates on developing total solutions for  seismic
processing  and  reservoir  modelling,  and will  provide  market
support in these areas.

The PCG will participate in joint projects with leading  European
based companies involved in petroleum exploration and production.

The  PCG  will be primarily located in Stavanger and  managed  by
Knut  Korsell.  The  staff  for  the group  will  be  located  in
Stavanger  and  in  Bergen.  The  full resources  of  the  Bergen
Scientific Centre will be available to the group.  In particular,
the Centre's IBM 3090 computing power will be available and there
will  be  close  interaction  and  support  from  the   technical
computing expertise already available in BSC.

For  further  information  please  contact:

Subject: SIAM Conference on Sparse Matrices

                  SIAM Conference on Sparse Matrices
                                   
                                   
        Sponsored by the SIAM Activity Group on Linear Algebra
                                   
                           Salishan Resort
                        Gleneden Beach, Oregon
                                   
                           May 22-24, 1989
                                   
                                   
OBJECTIVE:  The quickening pace of increasing computer power and
decreasing cost has made feasible the solution of new, larger, and
more complex problems.  Their solution requires new or improved
algorithms, while the architectural constraints imposed by the need
for high performance pose new difficulties in implementation.  The
research and applications community have responded to these needs with
a number of advances in the solution of sparse problems.

This conference will provide a forum for the presentation of the most
significant achievements in meeting these new challenges.  Theoretical
algorithms, new applications and implementations for vector and
parallel architectures will be presented.  We expect to have
contributions in all of the traditional areas of sparse linear
algebra, linear equations, eigenvalue problems, and least squares
problems, as well as recent developments in such areas as sparse
control problems and sparse optimization.  The conference is organized
to promote interchange of new ideas between the developers, the users
and the implementors of sparse matrix algorithms.  We encourage the
participation of users of sparse matrix algorithms in structural
engineering, computational fluid dynamics, computational chemistry and
other fields, as well as the participation of algorithm developers.

FORMAT:  The conference will be limited by the availability of hotel
rooms to approximately 150 participants.  There will be no invited
speakers.  Instead, 18 of the contributors will be chosen to give 45
minute presentations in non-parallel sessions over the three days of
the conference.  In addition, there will be opportunity in 12 informal
workshops, scheduled in four periods, for the other contributors to
present their accomplishments and to discuss with their colleagues the
needs and directions for future work.  All accepted abstracts, whether
for formal or informal presentation, will be distributed in the
conference program.

DEADLINE FOR PAPERS:  In keeping with the goal of presenting the most
current advances, the deadline for submissions is not until Feb. 1,
1989.  In selecting speakers, the committee will evaluate most
positively novel and unpublished work.  Promising work in progress is
appropriate for submission.

LOCATION:  The Salishan Resort is a first-class resort in an
attractive and secluded location on the beautiful Oregon Coast.
Contrary to usual anti-tourism propaganda, the weather at Salishan in
May is usually warm, sunny and dry.  The resort provides easy walking
access to the beach, and has a wide range of exercise facilities.  Its
location is ideal for exploring the Oregon Coast for those who may
want to arrive earlier or stay after the meeting.  Transportation from
the Portland International Airport (approximately 90 miles) will be
available at specified times.

PROCEEDINGS:  The SIAM Journal on Matrix Analysis will publish a
partial proceedings in a specially designated issue(s), consisting of
refereed contributions solicited from presentations at this
conference.
