**Subject: Hermitian Block Toeplitz Linear System**

Has anyone written software (Fortran, Fortran90, C, etc) which

solves a linear system of equations with the following form:

Tx=b where T is Hermitian and positive definite

and T is a block toeplitz matrix. The blocks T_{ij} are square

Toeplitz matrices. Also the blocks satisfy the relation

T_{ij} = conjugate{T_{ji}}

Block T_{11} is also Hermitian, although the other blocks are

not usually Hermitian.

We are currently applying a conjugate gradient algorithm to solve this

linear system, and are searching for a good preconditioner. Any suggestions

for a "good" preconditioner would be greatly appreciated.

I would also like to hear about any other methods that people are finding

practical to apply (fast vs superfast vs cg). Our blocks are typically

of size 512 by 512.

T may be required to be square initially (i.e., the same number of row and

column blocks), but may later be generalized to a rectangular form.

Thanks in advance!

**Subject: Is Your Software Safe for Negative Zero?**

Hi Nanet,

Please be aware that fortran 95 made a significant change in the SIGN

intrinsic function, and this change is now turing up in commercial

compilers. Namely, the sign function now distinguishes between +0

and -0. It is very easy to create negative zero in ieee arithmetic,

for example, -1.0 * 0.0 = -0.0. Many programs, ode itegrators for

example, use the sign function when constructing numerical derivatives

of user-supplied functions. These programs may perform differently

if compiled on an f95 compliant compiler.

**Subject: LOQO/AMPL Optimization Solver Available on the NEOS Server.**

The NEOS Server is now accepting problems submitted in AMPL format!

The first solver to accept problems in AMPL format is LOQO.

LOQO solves linear programming and convex quadratic

programming problems, or nonlinear optimization problems.

LOQO was developed by Robert J. Vanderbei.

Installation of the LOQO solver would not have been possible

without the help, guidance, and advice of Bob Fourer, David Gay,

and Bob Vanderbei.

You can try out LOQO by visiting the NEOS Server at

http://www.mcs.anl.gov/otc/Server

You can also use email; instructions are obtained by sending

neos@mcs.anl.gov one of the messages below:

**Subject: Parallel Linear Algebra Package Available**

Parallel Linear Algebra Package (PLAPACK) Release 1.0 available

During the last year and a half, we at UT-Austin have developed an MPI

based Parallel Linear Algebra Package (PLAPACK) designed to provide a

user friendly infrastructure for building parallel dense linear

algebra libraries. We are happy to announce the first public release

of the package. The Users' Guide

"Using PLAPACK: Parallel Linear Algebra Package"

has been available from The MIT Press since last spring.

WHAT IS DIFFERENT: PLAPACK provides three features not currently found

in other publically available parallel dense linear algebra libraries:

1) A matrix distribution that is a step towards one that is driven

by the natural distribution of an application,

2) An application interface for filling and querying matrices and

vectors,

3) A programming interface that allows the code to be written in

a way that closely resembles the way algorithms are naturally

explained, using object based (MPI-like) programming.

WHAT TO EXPECT: We have concentrated on providing an infrastructure

for building parallel dense linear algebra libraries. Thus, currently

only those who need only basic linear algebra operations (like the

level-1, -2, and -3 BLAS) will be immediately set to link to an

application. A release of a basic linear system solver package can be

expected shortly. We encourage people to use this easy-to-use

interface to build higher level algorithms, and contribute to the

project by submitting them to the library.

Thus, we provide all aspects required to build and interface with the

library, including data distribution, accessing data, transparent

communication, and an interface that allows algorithms to be expressed

at a higher level of abstraction.

Performance is good compared to other such libraries.

SO WHY USE PLAPACK? To speed development of custom parallel linear

algebra routines. To avoid dealing directly with indices and data

redistribution (i.e. inter-processor communication). Besides, it is

fun (quote from a satisfied customer).

WHAT IS DIFFERENT BETWEEN ScaLAPACK AND PLAPACK? Comparing ScaLAPACK

and PLAPACK is like comparing PVM and MPI.

WHAT PLATFORMS ARE CURRENTLY SUPPORTED? As of this moment, we provide

prebuilt versions for IBM, Convex, Cray, SGI, and Sun platforms

Only a C interface is currently supported, but then, most people by

now know how to interface C and Fortran.

SPONSORS: This project is sponsored in part by ARPA, DoE, The Intel

Research Council, and NASA. Also, the proceeds of the royalties for

the Users' Guide will be donated to UT-Austin to help support the

project.

ANNOUNCEMENT OF THE AVAILABILITY OF THE SLICOT LIBRARY ON FTP AND WWW

AND THE IMPLEMENTATION OF THE EUROPEAN NUMERICS IN CONTROL

NETWORK N I C O N E T

More about WGS AND SLICOT (http://www.win.tue.nl/wgs/wgs.html)

The objectives of WGS are first to bring together the existing numerical

software for control and systems theory in a widely available library,

called SLICOT, and to extend this library to cover as far as possible the

area of industrial applications.

The WGS started as a Benelux initiative in the early eighties, but now

operates on a more general European level.

More about NICONET (http://www.win.tue.nl/wgs/niconet.html)

WGS has attracted new partners (academia, research centers and industries)

with complementary expertise in order to implement a thematic Numerics

in Control network, entitled NICONET. This network is part of the specific

European Community programme on Industrial and Applied technologies

(BRITE-EURAM III) under the fourth framework programme (1994-1998) on

``Research and technological development'' and aims to coordinate the

development of robust numerical software for control systems analysis and

design.

Such software is an essential ingredient in modern computer aided control

system design (CACSD) and thus for the future of high-tech European industry.

More information is available in WGS newsletter 12, which can be obtained:

**Subject: New Book: Linear Algebra, Geodesy, and GPS **

Linear Algebra, Geodesy, and GPS

by Gilbert Strang and Kai Borre

Wellesley-Cambridge Press Box 812060 Wellesley MA 02181

fax 617 253-4358 phone 781 431-8488 email gs@math.mit.edu

640 pages (1997) hardcover ISBN 0-9614088-6-3

http://www-math.mit.edu/~gs

The book has three closely connected parts. The first is Linear Algebra,

which is the fundamental tool in positioning calculations. The second is

Geodesy, which includes the correct weightings for observation errors and

the development of least squares. The third is GPS, which we describe in

detail at several levels : first the basic structure of the GPS system, then

the algorithms that yield accurate positions from inaccurate pseudoranges,

and finally the Kalman filtering (and "Bayes" filtering) that give superior

accuracy in postprocessing a long series of observations.

If you wanted to order this book, I only need to ask for email with the best

mailing address. The book will come with an invoice ; a check to the Press

(not credit card) is perfect. The cost including domestic postage is $60.

For international orders the cost with surface postage is $62, and the new

Global Priority Airmail adds $5.

A large library of MATLAB files is associated with the book. They were

created by Kai Borre and are freely available on the web. We hope that these

M-files will help readers to use the more individual and experimental

processing that MATLAB offers, compared with large-scale software packages.

**Subject: Research Assistant/Post Doc at Univ. of Augsburg**

At the Department of Mathematics of the University of Augsburg we

currently have an opening for a

Research Assistant or Post-Doc

in the project Data-Local Iterative Methods (see

http://scicomp.math.uni-augsburg.de/stals/project.html) funded by the

Deutsche Forschungsgemeinschaft.

The project aims at designing the fastest algorithms for elliptic

partial differential equations with special attention to the

requirements of current high performance computer architectures. We

believe that the disappointing performance of many iterative methods is

due to a poor use of the cache architecture. Therefore we will examine

the possibility to restructure fast algorithms (like the multigrid

method) and design new variants with the goal of improving the cache

behavior.

In our present, first attempt we can solve Laplace's equation

discretized by 1 million unknowns in approximately 2 seconds on a single

processor SGI Power Indigo (R8000), but we expect to do significantly

better on more modern machines (that we are presently installing). We

also believe that the concepts behind the current code extend to more

general problems, but to explore this will be part of the ongoing

project. The work is in cooperation with the chair for Computer

Architecture of the Technische Universitaet Muenchen.

The ideal candidate would have a strong background in numerical

analysis, in particular in fast methods for elliptic PDE and the

analyis and the implementation of multigrid algorithms. Additionally,

the candidate should have an interest computer architecture issues.

A (German) Diploma or PhD in mathematics or computer

science is required and knowledge of German would be useful.

The salary will be according to DFG regulations up to BAT IIa.

Initially the position would be for a year with possible extensions for

up to 3 years.

Applications and enquiries should be sent to
