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,

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
co-sponsored by the Special Interest Groups for Linear Algebra and
Supercomputing of the Society for Industrial and Applied Mathematics.

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.
