**Subject: SLDRIVER, Interactive Sturm-Liouville Package**

The SLDRIVER interactive Sturm-Liouville package

The classical Sturm-Liouville problem (SLP) is

(-p(x) y')' + q(x) y = lambda w(x) y (1)

where y is a real function of x on a real interval a<x<b with appropriate

boundary conditions at a and b, and p, q and w are given functions. The

main numerical task is to compute eigenvalues and associated

eigenfunctions. Algorithms for (1) have been a model for attacking more

general problems such as matrix-vector SLPs and linear Hamiltonian

eigenproblems.

"Regular" SLPs generally pose few difficulties, but "singular" SLPs show

great variety of behaviour: the spectrum can comprise both eigenvalues and

continuous spectrum; the eigenvalues can form a finite set, or an infinite

sequence that may be increasing, decreasing or two-sided, bounded or

unbounded. Eigenvalues can lie within continuous spectrum. Good library

software has been available for some years and has gradually enlarged the

range of SLPs that can be reliably handled.

SLDRIVER is an interactive Fortran 90 program which supports exploration of

a set of Sturm-Liouville problems with the four SL-solvers (whose source

comes with the package):

SLEIGN, SLEDGE, SL02F and SLEIGN2.

It is now included in Collected Algorithms of the ACM and the supporting

articles will shortly appear in ACM Trans. Math. Software.

SLDRIVER contains the collection of 60 test problems compiled by Pryce and

colleagues and published in Pryce's 1993 book "Numerical solution of SLPs",

which offer a realistic performance test of the currently available codes.

It is simple to replace this collection by another one.

SLDRIVER has a simple textual menu interface which makes it easy to switch

solver, problem, eigenvalues required, etc. Computed results are written

out in the form of Matlab-compatible m-files which when executed allow

plotting and further analysis of eigenvalues/eigenfunctions within Matlab.

We hope that SLDRIVER will be a useful tool for research and education, and

encourage further development of Sturm-Liouville related software.

The package (version 4.1), including LaTeX of the User Guide, is available

currently by anonymous ftp from

ftp://ftp.rmcs.cranfield.ac.uk/pub/departments/seas/cised/numanal/

in these files:

sltar.gz gzipped tar archive of SLDRIVER in Unix format

slzip.exe self-extracting archive of SLDRIVER in MS-DOS format

The code of the two versions is identical, and has run under a number of

Fortran 90 systems.

**Subject: Aztec 2.0, A Parallel Iterative Package for Linear Systems**

NEW SOFTWARE ANNOUNCEMENT

Aztec 2.0: A parallel iterative package for the solving linear

systems arising in Newton-Krylov Methods, Version 2.0

http://www.cs.sandia.gov/CRF/aztec1.html

Authors: Ray S. Tuminaro, Charles H. Tong, John N. Shadid,

Scott A. Hutchinson, Lydie Prevost

Sandia National Laboratories

Albuquerque, New Mexico, USA

Aztec Version 2.0 Release Notes:

We have added several new features:

1) ilut preconditioner

2) ilu(k), bilu(k), icc(k) for k > 0.

2) arbitrary overlap in domain decomposition

3) equation reordering for incomplete factorization based on RCM algorithm

4) Matrix-free & user-supplied preconditioning interface

5) Improved flexibility. Solvers can be used as preconditioners.

Several new machines have been added to the Makefile including: Cray T3E and

Linux boxes.

A new matrix-free sample program has been included with the distribution.

We have fixed a bug in the MPI communication associated with AZ_transform().

We have fixed a couple of memory bugs in the domain decomposition.

Other minor bug fixes.

IMPORTANT: a few Aztec function parameters have changed. Mostly things like

using unsigned integers instead of signed integers. This may generate

warnings on some compilers unless you explicitly cast the parameters.

The User's Guide has been updated to reflect these changes.

Aztec is an iterative library that greatly simplifies the parallelization

process when solving the linear systems of equations Ax = b where A is a user

supplied nxn sparse matrix, b is a user supplied vector of length n and x is a

vector of length n to be computed. Aztec is intended as a software tool for

users who want to avoid cumbersome parallel programming details but who have

large sparse linear systems which require an efficiently utilized parallel

processing system. A collection of data transformation tools are provided that

allow for easy creation of distributed sparse unstructured matrices for

parallel solution. Once the distributed matrix is created, computation can be

performed on any of the parallel machines running Aztec: workstation clusters

(DEC, SGI, SUN, LINUX, etc.), Cray T3E, Intel TeraFlop, Intel Paragon, IBM SP2,

nCUBE 2 as well as other MPI platforms, vector machines or serial machines.

Aztec includes a number of Krylov iterative methods such as conjugate gradient

(CG), generalized minimum residual (GMRES) and stabilized biconjugate gradient

(BiCGSTAB) to solve systems of equations. These Krylov methods are used in

conjunction with various preconditioners such as polynomial or domain

decomposition methods using LU or incomplete LU factorizations within

subdomains. Although the matrix A can be general, the package has been designed

for matrices arising from the approximation of partial differential equations

(PDEs).

Aztec is publicly available through a research license. The code is

distributed along with technical documentation, example C and Fortran

driver routines and sample input files on the WWW at:

**Subject: PLAPACK R1.2 (BETA) Available**

During the last 2 1/2 years the PLAPACK project at UT-Austin has

developed an MPI based Parallel Linear Algebra Package (PLAPACK)

designed to provide a user friendly infrastructure for building

parallel dense linear algebra libraries.

The BETA release of R1.2 has a number of important additions:

1) In addition to the general and positive definite (dense) matrix

solver in R1.1, we now feature a QR decomposition based linear least

squares solver.

2) PLAPACK now includes a Fortran interface.

3) Although R1.1 was already competitive with other parallel dense

linear algebra packages, performance has noticeably improved:

Performance in MFLOPS/sec/processor on 16 node T3E-600 (300 Mhz),

streams turned on

| (Cholesky) | (LU w/ pivot)| (LU w/ pivot) | (QR)

| double real| double real |double complex | double real

n | R1.1 R1.2 | R1.1 R1.2 | R1.1 R1.2 | R1.1 R1.2

-------+------------+--------------+---------------+--------------

2000 | 90 130 | 66 79 | * 178 | * 73

5000 | 195 253 | 174 212 | * 332 | * 209

7500 | 245 303 | 228 268 | * 376 | * 272

10000 | 280 333 | 268 307 | * 397+ | * 312

12000 | 300 346 | 327 | * * | * *

(For the above performance results, complete solves were performed,

including related triangular solves. +The R1.2 performance for LU

double complex attaining 397 MFLOPS/sec/processor was for a problem

size of 9500.) This performance improvement was primarily due to a

reduction in communication overhead and more sophisticated

implementations of the factorization routines.

PLAPACK has been ported to platforms ranging from parallel

supercomputers like the Cray T3E and IBM SP-2 to Pentium based Beowulf

class systems running Windows NT or Linux.

Special Issue of Linear Algebra and Its Applications

ACCURATE SOLUTION OF EIGENVALUE PROBLEM

Deadline Extended to February 1, 1999

In the last several years, there have been a number of advances in the

accurate solution of eigenvalue problems. Many of the results have come from

the realization that eigenvalue algorithms that exploit the structure of the

problem can lead to more accurate eigenvalue and eigenvector computations.

Well known examples include faster and more accurate methods for solving the

symmetric tridiagonaleigenproblem, more accurate methods for computing the

singular value decompostion, and further understanding of the conditioning

theory for the non-symmetric eigenvalue problem.

To recognize these advances and to encourage further advances, submissions

are encouraged to a special issue of Linear Algebra and Its Applications

on Accurate Solution of Eigenvalue Problems. This special issue is in

coordination with the International Workshop on Accurate Solution of

Eigenvalue Problems that was held in University Park, PA on July 20-23, 1998.

The participants in the workshop have been strongly encouraged to submit

papers to the special issue. Submissions are also welcome from

non-participants as long as they are consistent with the themes of the

**Subject: Conference on Stochastic Optimization**

FIRST ANNOUNCEMENT

International Conference on

"Stochastic Optimization: Algorithms and Applications"

Location: Center for Applied Optimization, University of Florida

Organizers: Stanislav Uryasev (uryasev@ise.ufl.edu)

Panos Pardalos (pardalos@ufl.edu)

Stochastic programming is the study of practical procedures for

decision making under the presence of uncertainties and risks.

Stochastic programming approaches have been successfully used in a

number of areas such as energy and production planning,

telecommunications, forest and fishery harvest management,

engineering, and transportation. Recently, it was realized that the

practical experience gained in stochastic programming can be expanded

to a much larger spectrum of applications including financial

modeling, asset-liability management, bond portfolio management,

currency modeling, risk control, and probabilistic risk analysis. This

conference will focus on recent advances in theory and implementation

issues of stochastic programming algorithms, software, and

applications. The conference will feature approximately 30-40 invited

speakers during a three day period. Major topics to be covered in the

conference include: (1) advances in theory and implementation of

stochastic programming algorithms; (2) sensitivity analysis of

stochastic systems; and (3) stochastic programming applications.

ABSTRACT

In recent years, a large number of mathematical models have

appeared in different areas of science and engineering (control

theory, epidemiology, laser optics, viso-elastic behaviour) that take

into account not just the present state of a physical system but

also its past history. These models are described by certain classes

of functional differential equations often called delay differential

equations. This course presents a two-day introduction to delay

equations, and will cover both the analysis of delay equations and

numerical solution methods.

A detailed program & further information is available at
