Subject: Sine and Cosine Transforms on Crays

Hello NA-NET people,

I use VFFTPK subroutines in a CFD code I wrote. These routines account
for about 80% of the runtime. I am currently running the code on
both a C90 and a T90. The Cray LibSci FFT routines provide substantially
better performance over simply vectorized versions of VFFTPK. However,
the Cray libraries do not provide routines for just SINE or COSINE
transforms. I realize that these just require proper pre and post
processing of the data using the Cray routines. If anyone has
already spent the time writing these I would appreciate information
on where to find them. Thanks for your time.

Subject: School on Wavelets in the Geosciences

International Association of Geodesy

Announcement and registration
October, 4 - 9, 1998
At the Delft Institute for Earth-Oriented Space Research
Faculty of Civil Engineering and Geosciences
Delft University of Technology
Delft, The Netherlands

Objectives of the school

The basic objective of the School is provide the necessary information to
understand the potential and limitations of the application of wavelets in
the geosciences. This includes:
* the mathematical representation in one and more dimensions like on the
* the properties as compared to Fourier techniques
* the signal representation and analysis ability
* the use of operators in terms of wavelets
* gaining experiences with wavelets using examples from geosciences in
computer exercises


The course will last for six days and contains three major subjects. Every
subject will be covered in two days time. All topics will be supported by
practical exercises on the computer with examples from geodynamics,
topography representation, gravity field modelling etc.
The lectures and subjects are:
1. Prof. Dr. Peter Maass, Institute of Mathematics, Faculty of Mathematics
and Natural Sciences, University of Potsdam, Germany;
One dimensional wavelets. The link with Fourier theory is a starting
point to introduce continuous wavelets, discrete wavelets on intervals,
multiresolution, analysis and synthesis using wavelets, operators,
compression and filtering with wavelets.
2. Dr. Wim Sweldens, Mathematical Sciences Research Centre, Lucent
Technologies Bell Laboratories, Murray Hill, NJ, USA;
Tensor product wavelets, 2nd generation wavelets. Special emphasis will
be put on the choice of wavelets in multidimensions. Multiresolution
analysis for arbitrary surfaces, efficient data representation as
well as efficient procedures for evaluation of integrals or solving
integral equations will be elaborated in more detail.
3. Prof. Dr. Willi Freeden, Geomathematics Group. Department of
Mathematics, University of Kaiserslautern, Germany;
Wavelets on closed surfaces. The link with Fourier theory on the sphere
(spherical harmonics) is a starting point to introduce continuous
wavelets, discrete wavelets, multiresolution, analysis and synthesis
using wavelets, operators, compression and regularisation with
wavelets. This will be generalised to closed surfaces.
Lecture notes will be provided at the start of the school.

Who could attend

The school aims to provide Ph.D. students, researchers and staff members
with an overview on wavelet methods and its applications in geosciences at a
post graduate level (master). The participants should have a University
level education with an adequate mathematical foundation. Basic knowledge on
potential theory, functional analysis, numerical analysis or systems and
signals is recommended. The minimal number of attendants is 20 the maximum
40. The registration deadline is July 1st 1998; the fee Dfl. 450,-

Methods. Papers are solicited on all aspects of parallel computing
methodology, including new and innovative methods. Papers on parallel
strategies for shared and distributed memory architectures, heterogeneous
clusters of workstations, and Pile-of-PCs are sought. Of particular
interest are papers discussing applications of parallel algorithms and
the effective use of parallel computing methods in industrial applications.

Paper abstracts are due to the organizer by March 13, 1998 and may be
