                                                                  OVERVIEW


PARLE is an international, european!based conference focusing on the
parallel processing subdomain of Informatics/Information Technology. It
is organised annually on a non!profit making basis to act as a European
forum for interchange between those working or interested in the domain,
from both academia and industry.


Ever increasing demands are being made on computer technology to provide
the processing power necessary to help understand and master the
complexity of natural phenomena and engineering structures. Within human
organisations ever more processing power is needed to master the
increased information flow. Many so!called !Grand Challenges! have been
identified as being orders of magnitude beyond even the most powerful
computers available today.


Parallel processing technology offers a solution to providing the
necessary power and is therefore generally recognised as a strategically
important technology. By taking many basic processing devices and
connecting them together the potential exists of being able to achieve a
performance many times that of an individual device. However it is still
an important topic of research to discover how to do this optimally and
then to be able to effectively exploit the potential power through real
applications solving real!world problems.




                                                          WHO SHOULD ATTEND?


PARLE!93 has been designed to be attractive for a very wide!ranging
audience. It will appeal to academic researchers and students working in
the field of parallel processing or related areas. It will also appeal to
industrial workers in the area wishing to discover the latest ideas,
techniques and approaches. The Tutorial Programme offers an opportunity
for anyone interested in learning the state!of!the!art in some of the
newest, most exciting areas of parallel processing from world renowned
experts. A special Esprit project poster display will provide an overview
of many projects funded by the European Commission. The Industrial
Programme, consisting of both Vendor Presentations and an Exhibition,
offers the opportunity to gain first!hand experience of the commercial
products available today.


PARLE!93 offers an unrivaled opportunity for anyone interested to learn
more about parallel processing, whether expert or novice.

coverage:




TUTORIAL 1: MOLECULAR BIOINFORMATICS


Presenter: Thomas Lengauer, GMD, St. Augustin, Germany


Objectives
This tutorial will give an overview of Molecular Bioinformatics, its
promises, its limitations, and its scientific challenges. Molecular
Bioinformatics is an area in applied computer science which is in general
terms concerned with the development of methods and tools for analysing,
understanding, reasoning about and, eventually, designing large
biomolecules such as DNA, RNA, and proteins, with the aid of the
computer. The complexity of these molecules necessitates sophisticated
algorithmic and organizational models and techniques in order to keep the
computational requirements within acceptable ranges. High-performance
computing and parallel computation are an important aspect of Molecular
Bioinformatics. On the one hand, chemists have a well-developed tradition
of using high-performance computers. On the other hand, many of the
problems involved can only be tackled if the highest computing power
available is used effectively.


Contents
          I Introduction to the biomolecular background.
          II Alignment of biomolecular sequences (DNA, RNA, Proteins) and the
                    detection of evolutionary relationships between such sequences
                    (phylogenetic trees).
          III Modeling of large biomolecules, including the prediction and
analysis of
                    secondary and higher-level structure as well as spatial
conformations
                    (folding).
          IV Molecular dynamics and simulations of interactions between
biomolecules.


Biography
Thomas Lengauer is a director of the Institute of Foundations of
Information Technology at the Federal Research Center for Computer
Science (GMD) in St. Augustin, Germany. He is also Professor of Computer
Science at the University of Bonn. His research interests are in the area

TUTORIAL 2: NEURAL NETWORKS, FROM THEORY TO APPLICATIONS


Presenter: Francoise Fogelman Soulie, LRI, University of Orsay, France


Objectives
Participants in this tutorial will learn about advanced Neural Network
techniques. Efficient methods will be given for training the complex,
hybrid architectures required for real-world problems. Through a survey
of applications, the tutorial will assess the technology's realizations
and provide a development methodology. Parallel implementations of Neural
Networks will be discussed.


Contents
          I General introduction to Neural Networks. Overview of industrial
                    implementations.
          II Survey of major Neural Network learning algorithms: Adaline,
Perceptron,
                    Multi-Layer Networks, Learning Vector Quantisation, Radial
Basis Function,
                    Topological Maps.
          III Neural Networks and Pattern Recognition: theoretical links with
the
                    Bayesian Classifier, computing and generalisation capabilities
of Multi-
                    Layer Networks, links of Multi-Layer Networks with Principal
Component
                    Analysis and Discriminant Analysis.
          IV Architectures for real-world applications. The need for modular
design.
                    Cooperation of hybrid techniques (Neural Networks and
conventional).
                    Training algorithms and examples.
          V Development methodology of Neural Network applications:

TUTORIAL 3: OBJECT-ORIENTED CONCURRENT PPROGRAMMING


Presenter: Jean-Pierre Briot, Dept. of Information Science, The
University of
                      Tokyo, Japan and LITP, Institut Blaise Pascal, Paris, France.


Objectives
This tutorial introduces the basic concepts and methodology of
object-oriented concurrent programming. Object-oriented concurrent
programming is a natural integration of object-oriented programming and
concurrent programming. The resulting programming methodology allows
large programs to be decomposed into a collection of small modules that
run and interact concurrently and which are capable of exploiting
parallel hardware. The tutorial covers both a progressive introduction to
the concepts, a number of program examples, and a survey of the current
state of the art.


Contents
          I Introduction
          II From Passive Objects to Active Objects
          III Concepts
          IV Example of Programming Language: ConcurrentSmalltalk
          V Programming Methodology and Examples in ConcurrentSmalltalk
          VI Implementing Active Objects: Actalk
          VII The Actor Model of Computation
          VIII Survey/Comparison of Main OOCP Languages
          IX Present and Future, Conclusion, and Bibliography

Jean-Pierre Briot is a researcher at LITP, University of Paris-VI. He is
currently visiting the Department of Information Science, University of
Tokyo. He participated in the design of several OOCP languages and
platforms, and their applications to computer music and distributed AI.
He co-headed an ESPRIT parallel computing action to develop an OOCP
programming environment for multiprocessors. He has performed tutorials
on OOCP at the main OOP conferences (TOOLS, ECOOP and OOPSLA).




TUTORIAL 4: AUTOMATIC PARALLELISATION FOR DISTRIBUTED-MEMORY SYSTEMS


Presenter: Hans P. Zima, Institute for Software Technology and Parallel
Systems,
                      University of Vienna, Austria


Objectives
In this tutorial, we describe the current state of the art in compiling
procedural languages (in particular, Fortran) for distributed-memory
multiprocessing systems (DMMPs), analyze the limitations of these
approaches, and outline future research. We introduce the language
extensions of Vienna Fortran which allow the user to write programs for
DMMPs using global addresses, and to specify the distribution of data
across the processors of the machine. We also introduce Message Passing
Fortran (MPF), a Fortran extension that allows the formulation of
explicitly parallel programs which communicate via explicit message
passing.


Contents
          I Current programming practice on DMMPs by means of a simple
example.
          II A programming model is introduced and an informal overview of
the relevant
                    elements of Vienna Fortran and MPF is provided.
          III Basic parallelisation is described by discussing the individual
phases
                    involved in the translation from Vienna Fortran to MPF. This
includes a
                    discussion of the procedures and various optimisation
techniques.
          IV Additional optimisation methods and advanced parallelization
techniques
                    including run-time analysis.
          V An overview of related work and a discussion of open research
issues.


Biography
Hans P. Zima is Professor for Computer Science, University of Vienna,
Austria, and Adjunct Professor, Computer Science, Rice University, USA.
