Subject: New Edition of PLTMG Package

PLTMG 8.0 is a package for solving elliptic partial
differential equations in general regions of the plane.
It is based on continuous piecewise linear triangular finite elements,
and features adaptive local mesh refinement, multigraph iteration,
and pseudo-arclength continuation options for parameter
dependencies. The package includes an initial mesh generator
and several graphics packages. Full documentation is provided in
PLTMG: A Software Package for Solving Elliptic Partial Differential Equations
- Users' Guide 8.0 (ISBN 0-89871-409-5), available from SIAM Publications.
PLTMG is provided as Fortran (and a little C) source code, in
both single and double precision versions. The included X-Windows GUI uses the
default Athena Widget set, and makes calls to standard library routines
of the X-Windows system, which must be loaded along with the PLTMG software.
PLTMG is available from Netlib and Mgnet.

Subject: Conference in Honor of Olga Ladyzhenskaya

First announcement and call for contributed papers

Conference in honor of Olga Ladyzhenskaya
Recent Trends and Advances in PDEs and Numerical PDEs

August 2-5, 1998
Iowa State Univeristy
Ames, Iowa

Conference web site

Supported by the National Science Foundation, the Iowa State University
Miller Lecture Fund and the Department of Mathematics

Partial differential equations (PDEs) is the language of much of
science and engineering so that advances in PDEs and their approximate
solution are of continuing importance to applications. The conference
has as one of its goals to foment cross-fertilization by bringing
together a variety of researchers in the wide, wide world of PDEs. We
plan to facilitate individual and small group interactions. The
conference will have a general theme of recent advances and trends in
the theory and computation of PDEs, especially nonlinear ones. We will
focus on models and theoretical and computational results that are of
importance in applications. The inclusion of a wide variety of
theoretical and computational topics in the conference will provide
for an exchange of information between researchers working on
different problems who may ordinarily not interact with each other or
who might not learn about new developments that could help their own
research programs. This aspect of the conference may especially
benefit junior mathematicians who will be exposed to the great variety
of approaches and models that the general PDE community has developed.

Subject: Papers Sought for Parallel and Distributed Computing


The area of PARALLEL AND DISTRIBUTED COMPUTING has matured to the point
when it could benefit from papers providing a broader perspective on the
discipline and attempting to introduce order into the rapidly expanding
knowledge. To address this need the new journal -- Parallel and
Distributed Computing Practices ( -- decided
to publish OVERVIEW papers.

An overview paper is expected to cover a subarea of parallel and/or
distributed computing. It is supposed to contain a historical perspective
on the developments up to date as well as information about the state of
the art. It should also contain the description of what research is
currently considered the most important and which roads are considered to
be the most promising to lead to the answers. The paper should contain
extensive bibliography. It is crucial that the paper be written in such a
way as to be accessible to computer professionals who do not have detailed
knowledge of the subject. All papers are refereed against a specially
designed set of criteria matching their special nature (see the WWW site
for more details). Due to the nature of the endeavor we expect the
overview papers to be longer than the papers typically accepted for
journal publication.

I am happy to announce that the first issue (in print now) contains an
overview paper: "Asynchrony in Parallel Computing: From Dataflow to
Multithreading" by J. Silc, B. Robic and T. Ungerer. It is a rather
extensive study (with 236 references) providing an excellent source of
information about the subject.

I would like to invite all everyone interested in contributing an overview
paper to contact the Editor-in-Chief (Marcin Paprzycki) at: to discuss the details of the project.

Premi=E8re annonce

Dans le cadre de notre s=E9minaire, nous organisons =E0 Dijon trois demi-journ=E9es
d'expos=E9s sur le th=E8me ``M=E9thodes Num=E9riques". Deux demi-journ=E9es seront
consacr=E9es plus particuli=E8rement au domaine de l'Optimisation. La troisi=E8me
demi-journ=E9e sera consacr=E9e =E0 d'autres domaines ( Equations aux d=E9riv=E9es
partielles,th=E9orie du contr=F4le ...). Le but de ces demi-journ=E9es est de
faire se rencontrer des math=E9maticiens de divers horizons et de faire le
point sur certaines m=E9thodes num=E9riques.

Conf=E9renciers :

- L. Carraro, D=E9partement 3MI, Ecole des Mines de Saint-Etienne, France :
``Quantification de l'incertitude sur la production d'un reservoir p=E9troli=

- J.C. Culioli, Ecole des Mines de Paris, France :

- J.P. Gauthier, Universit=E9 de Dijon, France :
``Une th=E9orie de l'observation d=E9terministe, et des applications."
