Dear Members of Na-net,
My colleague is interested in computer programs (source code preferred)
and/or papers related to *local* interpolation of a bivariate function f(x,y)
given by a set of scattered data points {[x_i,y_i,z_i]: i=1,...,N}.
Any hints and suggestions are very welcome. Many thanks in advance.

Subject: Fast Parallel Matrix Multiplication
This mail is a response to the request for fast matrix multiplication
techniques. A paper we have recently finished seems
relevant to mention here (title and abstract are included.)
Please let me know if more information is needed.
A copy of the source code will be provided upon request.
TITLE: A Massively Parallel Method for Matrix Multiplication
Based on Strassen's Method
ABSTRACT: We present the first parallel method
for matrix multiplication on distributed-memory architectures
based on Strassen's method. Our tests, performed on an Intel Paragon,
show that our method is systematically faster
than all existing parallel methods.
The larger the matrices are, the greater is the improvement
of our method. For matrices of order $M= 5000$, our
method is about five times faster than the Ring method coupled with the
traditional method for matrix multiplication,
a typical method on distributed-memory machines.
Also, we have noticed nearly perfect speedup when the processor number is
divisible by $7$. When the processor number is not
divisible by $7$, we have also achieved a reasonable speedup.

Subject: Products of Fourier Transforms
I have received the following question from a graduate student in engineering.
Can anyone be of help. Please respond directly to Tim Haynes
tim@enws123.eas.asu.edu
I am interested in computing Convolution Sums using two-
dimensional FFT's and for up to quartic nonlinearities:
N/2-1 K/2-1
------ ------
u1(i,j)= \ \ u1hat(k,n)exp(i k x(i))exp(i n y(j))
/ /
------ ------
n=-N/2 k=-K/2
N/2-1 K/2-1
------ ------
u2(i,j)= \ \ u2hat(k,n)exp(i k x(i))exp(i n y(j))
/ /
------ ------
n=-N/2 k=-K/2
.....similar definitions for u3(i,j) and u4(i,j). Here
u1(i,j) is the physical quantity on the (x,y) grid and
u1hat(k,n) are the corresponding Fourier coefficients. I want
to compute the Fourier coefficients of the nonlinear term
V(i,j)=u1(i,j)*u2(i,j)*u3(i,j)*u4(i,j) given
u1hat(k,n)...u4hat(k,n). This is typically done by (1)
performing inverse FFT on the u1hat....u4hat to get u1...u4
in phyiscal space, (2) multiplying u1...u4 in physical space
to get V, (3) computing Vhat by forward FFT on V(i,j). This
method produces aliasing errors, which could be removed by
"padding" or "phase-shifting". "padding" and "phase-shifting"
require significantly more computations to remove the
aliasing errors. Is there a cheaper way to remove these
aliasing errors? I compute these nonlinear terms at each step
of an evolution problem, using 2nd-order backward
differencing for the time-like variable.

Summary:
The book begins with a discussion of the well-known grid generation
methods for logically-rectangular grids, along with a description of
how to use the generated grids to solve steady-state (elliptic) partial
differential equations. The remainder of the book is devoted to a
discussion of variational grid generation techniques. The known
practical algorithms are described in detail, and in addition,
the reader is also brought up to date on the current research frontiers.
A large number of example grids are given and the book comes with a
floppy disk that contains program for generating grids and solving
partial differential equations.
The book is suitable as a text for a advanced undergraduate or graduate text.

Subject: Workshop on Mathematic Problems in Industry
Announcing A WORKSHOP ON MATHEMATICAL PROBLEMS IN INDUSTRY May 16-20, 1994
presented by
The Program in Applied Mathematics of the University of Colorado at Boulder
The Mathematics Department of Colorado State University
The Mathematics Department of the University of Colorado at Denver
In order to help meet the need for greater interaction between researchers
in industry and applied mathematicians from the academic community, a
workshop will be held in Boulder, Colorado during the week of May 16-20,
1994. The workshop is modelled upon successful programs which have been
held for many years at Oxford and RPI.
Applications are invited from individuals in industry and other research
establishments who would like to propose scientific problems for discussion
at the workshop. The problem may be at any stage of mathematical
formulation ranging between the two extremes: a problem which is yet to be
modelled, and one which has been completely reduced to a problem in
analysis and/or computation.
Academic participants in the workshop will include faculty and students
from Colorado Univerisities as well as representatives from other
institutions. A written report of the workshop results will be prepared by
the participants for the use of the industrial representative.
A fee of $1,000 will be charged to each industry participant bringing a
problem to the workshop. Industry representatives who do not bring a
problem, but do participate in the workshop will be charged a $250
registration fee. There is no registration fee for academic participants.
To facilitate planning for the workshop, we request that a brief one-page
description of each proposed problem be submitted by March 1, 1994 to one
of the members of the organizing committee.

Subject: Object-Oriented Numerics Conference
THE SECOND ANNUAL
OBJECT-ORIENTED NUMERICS CONFERENCE
April 24-27, 1994
Sunriver, Oregon
This conference provides a forum where computer scientists and
scientific programmers can discuss how to use object-oriented
programming techniques to more effectively write complex scientific
codes. As numerical programs are becoming more and more complicated,
people are looking for ways to manage this complexity. Object-
oriented programming gives you the ability to write code at a higher
level of abstraction, allowing you to reduce the complexity of
numerical programs. Anyone and everyone who is currently working in
object-oriented numerics, or would like to, should not miss this
conference!
There will be approximately 38 technical presentations and a poster
session in which workers in the field will present the results of
their latest efforts in object-oriented numerics. Session topics
include:
- Components - Modeling
- Tools/Optimization
- Design/Languages
- Components - Optimization/Linear Algebra
- Parallel - Components, Applications, and Environments
Preliminary Programs available now.

Subject: Position at CWI, Amsterdam
At CWI, in the Department of Numerical Mathematics, a vacancy exists for
the position of junior researcher in the field of CFD.
The research subject concerns the development and application of
solution-adaptive, sparse multigrid methods for the 3D, compressible
Navier-Stokes equations. (Sparse grid methods are a new, promising
approach for efficient 3D computations.)
The research tasks are both theoretical (numerical analysis) and
practical (implementation and testing), and are carried out in
the framework of a European Communities R&D program (BRITE-EURAM
Aeronautics Program). The results are directed towards application
in some major European aerospace industries.
The candidate should hold a recent M.S. degree and be familiar with
CFD-research. The research is expected to lead to a Ph.D. degree.
The position holds for four years at a maximum. (No educational or
organizational obligations exist.)
Further information about the position can be obtained from
prof.dr. P.W. Hemker (tel: +31.205924108, e-mail: P.W.Hemker@cwi.nl), or
