Subject: Assistance with Knapsack/Assignment Problem

Dear members of Na_Net,

I would like to request assistance to solve the following problem :

I have i = 1, ...,N satellites and j = 1,...,M ground stations with M > N.

d(i, j) = distance (km) between the satellite i and the ground station j

x(i,j) = 0 if no assignment between the satellite i and the
ground station j
= 1 if assignment between the satellite i and the
ground station j

So the problem is:

Minimizes {Sum_i Sum_j [(d(i,j) * x(i,j)] }

with constraints :

[Sum_i=1_to_N {x(i,j) =< 1} ] for each ground station j = 1,....,M

[Sum_j=1_to_M {x(i,j) = 1} ] for satellite i = 1, ..., N

Actually, I am looking to a code which accept a matrix interface to
define the problem ( and not a classic interface of the linear
programming codes).

Do you have algoritms / codes to solve this problem ?

Free source codes in Fortran (or C ) are mostly convenient, but any other
pointer or reference is also appreciated.

Best regards

Subject: Faster DFTs than FFTW

I'm pleased to announce the availability of djbfft 0.70. This version
supports in-place real4, real8, complex4, and complex8 convolution.

djbfft is much faster than FFTW on the Pentium and Pentium MMX. I have
not yet adapted it to other architectures, so it is only a little bit
faster than FFTW on the Pentium Pro and Pentium II.

See http://pobox.com/~djb/djbfft.html for further information.

Subject: Automatic Differentiation Version of DONLP2

A new AD version of Peter Spellucci's NLP package DONLP2 has been
released. It uses the TAMC utility of Ralf Giering.

ftp://plato.la.asu.edu/pub/donlp2/donlp2_td.tar.gz
http://plato.la.asu.edu/donlp2.html

- convenient interactive automatic differentiation with included
small script; no implementation of TAMC necessary
- general f77 standard with very few exceptions, no rewriting
of function statements required, no control statements

An online version of DONLP2 can also be accessed via the NEOS Server at
Argonne National Laboratory.
http://www.mcs.anl.gov/home/otc/Server/neos.html
It is intended for testing purposes and accepts input in AMPL. It uses
AMPL's automatic differentiation feature.

Subject: Multigrid Software Package

More Efficient Parallelizable MUDPACK

A new version 4.0 of the multigrid software package MUDPACK is now
available on the world wide web. The web site

<http://www.scd.ucar.edu/css/software/mudpack>

the source code after signing software licensing agreement with the
University Corporation for Atmospheric Research. Since it inception,
portions of MUDPACK have been distributed to hundreds of users from
foreign institutions and within the U.S. The new version was created
to simplify and modernize the package. MUDPACK 4.0 has been passed
through fortran verification software and compiled and executed on
a variety of platforms with both fortran 77 and fortran 90. The
resulting streamlining has yielded code which is more efficient and
more amenable to parallelization than the earlier versions.

MUDPACK 4.0 replaces and is incompatible with earlier versions. The
software includes a suite of portable fortran programs which automatically
discretize and use multigrid techniques to generate second- and fourth-order
approximations to elliptic Partial Differential Equations (PDEs) on
rectangular regions. The elliptic PDEs can be real or complex in two-
and three-dimensions with any combination of mixed derivate, specified, or
periodic boundary conditions. Multigrid V or W cycles which use point,
line(s), or planar relaxation and fully weighted residual restriction are
available for algorithm tuning to obtain optimal multigrid performance.
MUDPACK was written to avoid repeated "re-invention of the wheel" in human
code development time which can be at least as important as saving machine
cycles.

ParMETIS 2.0: A Parallel Graph Partitioning and Sparse Matrix Ordering Library

URL: http://www.cs.umn.edu/~metis
URL: http://www.cs.umn.edu/~karypis/metis

We would like to announce the release of version 2.0 of the ParMETIS library.
ParMETIS is an MPI-based parallel library that implements a variety of
algorithms for partitioning unstructured graphs and for computing
fill-reducing orderings for sparse matrices. ParMETIS is particularly suited
for parallel numerical simulations involving large unstructured meshes.
For these computations, ParMETIS dramatically reduces the time spent in
communication by decomposing the mesh in a way that balances the load and
minimizes the number of interface elements.

ParMETIS's algorithms are based on the multilevel partitioning and fill
reducing ordering algorithms that are implemented in the widely used serial
package METIS. ParMETIS extends the functionality provided by METIS by
including routines that are especially suited for parallel computations and
large scale numerical simulations.

ParMETIS provides the following four major functions:
- Partition an unstructured graph.
- Improve the quality of an existing partition.
- Repartition a graph that corresponds to an adaptively refined mesh.
- Compute a fill-reducing ordering for sparse direct factorization.

Here is a list of the major changes in version 2.0
- Improved support for repartitioning graphs corresponding to adaptively
refined meshes.
* Two new adaptive repartitioning routines have been added that are based
* The directed diffusion algorithm has been improved and uses a newly
developed wavefront formulation.
- The number of partitions have been de-coupled from the number of processors.
you can now use the parallel partitioning algorithms to compute a k-way
partitioning independent of the number of processors that are used. This
is particularly useful for parallel computers consisting of clusters of
SMPs.
- The names and calling sequences of all the routines have changed to make it
easier to call the various routines from Fortran.
- The partitioning and ordering algorithms in ParMETIS now utilize various
portions of the serial METIS library. As a result, the quality of the
partitionings and orderings have been improved.

Information text:

"This book teaches the basic methods of partial differential equations
and introduces related important ideas associated with the analysis of
numerical methods for those partial differential equations. Standard
topics such as separation of variables, Fourier analysis, maximum
principles and energy estimates are included. Numerical methods are
introduced in parallel to the classical theory. The numerical
experiments are used to illustrate properties of differential equations
and theory for finite difference approximations is developed. Numerical
methods are included in the book to show the significance of
computations in partial differential equations and to illustrate the
strong interaction between mathematical theory and the development of
numerical methods. Great care has been taken throughout the book to seek
a sound balance between the analytical and numerical techniques. The
authors present the material at an easy pace with well-organized
exercises ranging from the straightforward to the challenging. In
addition, special projects are included, containing step by step hints
and instructions, to help guide students in the correct way of
approaching partial differential equations. The text would be suitable
engineering. Necessary prerequisites for this text are basic calculus
and linear algebra. Some elementary knowledge of ordinary differential
equations is also preferable.

position for a POST-DOC.

Research description

Weather forecast and climate models often use spectral or
pseudo-spectral numerical methods for solving the differential
equations that describe the atmospheric motions. Compared to
grid-point numerical methods, e.g. based on finite volumes, such
methods lose their advantage when very fine grids are used.
As a result, there is a renewed interest in grid-point methods
for atmospheric hydrodynamical calculations.

The long term goal of the project is a comprehensive comparison
between newly developed and existing numerical methods, taking
into account the issues of space grid selection and discretization,
use of extremely fine grids, long time integration, and massive
parallelism. The comparison should attempt to answer the question:
which numerical grid-point method is most promising for future
atmospheric hydrodynamical calculations.

During the first half of the project the research will focus on
the shallow water equations on the sphere. These equations may be
considered as a simplified set of atmospheric motion equations.
During the second half, the attention will then gradually shift
to a full set of atmospheric motion equations.

Applicants are expected to have done their PhD research in numerical
mathematics, preferably on PDEs, computational fluid dynamics or in
meteorology with a strong numerical background. Applications from
candidates who are about to finish their PhD-work are also welcome.

Working periods and places will probably be: first half of the
project duration at GMD near Bonn, second half at CWI in Amsterdam.
Prolongation from two to three years will be decided within the
project.

Further information can be obtained from Dr. J.G. Verwer at CWI
(+31-20-5924095; Jan.Verwer@cwi.nl), Prof. U. Trottenberg at GMD
(trottenberg@gmd.de) and Dr. W. Joppich at GMD (+49-2241-142748;
