Subject: Sparse, Symmetric, LU-decompostion

I am looking for a code to compute the LU-decomposition of a
sparse, symmetric matrix. I would like a routine which pivots
and minimizes the fill-in. Does anyone have such a code or
know where I can get one?

Any help is greatly appreciated.

Subject: IBG, Geometry and Grid Generation Library

IBG Version 1.1

IBG is a library of routines written in ANSI C for geometry description and
grid generation. It allows unstructured simplicial grid generation in 1D, 2D
and 3D in different regions and on their boundaries without any restrictions
for the topology, with user-controlled isotropical or anisotropical refinement,
based on a combined octree/Delaunay technique. We have good grid quality
especially inside the regions (obtuse angles only in the neighbourhood of
boundary) and approximately linear time dependence.

A nonstandard interface for the geometry description will be used. The
geometry description part allows to create and modify this interface.
Possibilities for geometry description are volume grids (f.e. from the
previous time step), boundary grids, pixmaps, a function defining the region
for a given point. They can be modified with characteristic functions for the
parts which have to be changed. Other possibilities (f.e. boundary splines,
boolean operations) can be easily implemented if necessary.

The documentation is available in different formats (ASCII, Postscript,
DECWindows Bookreader).

Subject: Invitation to Launch of SEL-HPC

An open invitation to the launch of the

London and South-East Centre for High Performance Computing (SEL-HPC)

and its Education and Training programme

10th May, 2.30pm
at ULCC, 20 Guildford Street, London WC1N 1DZ

At the launch you will be able to hear about SEL-HPC's plans for assisting
development of HPC awareness in all Higher Education Institutions in the
London and South-East region through Education and Training and related
activities. In addition, you will be able to find out how HEIs can become
formal Associates of SEL-HPC or collaborate with its programme. The formal
presentations will be followed by an informal reception to celebrate the
Centre's launch.

SEL-HPC is a consortium formed by the London Parallel Applications Centre,
the University of Greenwich, the University of Kent and ULCC and is one of
five such regional centres of expertise funded on behalf of the Higher
Education Funding Councils for England, Scotland and Wales through the
Joint Information Systems Committee (JISC) New Technologies Initiative. The
other regional centres are located at University of Edinburgh, University
of Manchester, University of Southampton and University of Wales (Cardiff).
In addition, there is a centre of expertise supported at Queen's
University, Belfast. As regional centres, each will be concentrating on the
needs of the HEIs in its own region and this launch meeting gives an
opportunity for those in London and the South-East to find out about their
HPC Centre and its plans and to provide input to its further development.

SEL-HPC's planned activities include designing a comprehensive range of HPC
courses for use in staff and postgraduate training - some courses will be
given as part of the programme and course materials will be made available
to trainers at other sites. Topics will cover:

introduction to HPC systems
basic parallel methodologies
parallel languages, e.g. HPF/Fortran 90, occam2.5
SIMD and MIMD architectures
workstation and supercomputer interaction
applications techniques
software tools for parallel environments

The study of networking and workstation clusters will be carried out in
programmes linked to the Centre thereby ensuring early incorporation of
developments into the training courses. Other areas of investigation will
include interdisciplinary applications and the support of technology
development. The consortium also intends to foster industrial collaboration
where appropriate by technology transfer and joint projects.

SEL-HPC can provide access to a wide range of HPC hardware to support
education and training activites, including the Convex at ULCC, an
8192-processor MasPar, a 155-node Meiko, many other multi-transputer and
i860 machines, and several DAPs.

Subject: Fifth SIAM Applied Linear Algebra Conference

June 15th - 18th

The organizing committee for the 1994 Applied Linear Algebra
Conference is placing great importance on the poster sessions, and
wishes to encourage the presentations of high quality posters.

To this end we are soliciting posters for presentation at the
conference and will be awarding a prize for the best poster. It is
not necessary to have submitted a paper in order to bring a poster -
do use the poster session to tell us about your work.

Posters that do accompany papers should not reproduce the paper, but
should be regarded as an opportunity to supplement and advertize the
paper, perhaps by highlighting or amplifying important features.

The best poster will be judged upon both the content and presentation
of the poster, and the prize will be presented at the conference

A display area of 4ft (high) by 6ft (wide) will be available for
posters, and authors are expected to be present during their
half-hour attended poster session and the following common-interest
session in order to facilitate discussion. It would be helpful to
inform SIAM in advance if you intend to bring a poster, but this is
not essential. It is more important that you bring your poster!
