Sixth International Workshop on
aPpplications of declArative
and object-oriented Parallel Programming
(PAPP 2009)

part of
The International Conference on Computational Science
May 25-27, 2009, Baton Rouge, Louisiana, U.S.A.


Aims and scope

Computational Science applications are more and more complex to develop and require more and more computing power. Bill McColl's post Sequential Computing Considered Harmful is an excellent summary of today's situation. Sequential computing cannot go further. Major companies in the computing industry now recognizes the urgency of reorienting an entire industry towards massively parallel computing (Think Parallel or Perish).

Parallel and grid computing are solutions to the increasing need for computing power. The trend is towards the increase of cores in processors, the number of processors and the need for scalable computing everywhere. But parallel and distributed programming is still dominated by low-level techniques such as send/receive message passing. Thus high-level approaches should play a key role in the shift to scalable computing in every computer.

Algorithmic skeletons, parallel extensions of functional languages such as Haskell and ML, parallel logic and constraint programming, parallel execution of declarative programs such as SQL queries, genericity and meta-programming in object-oriented languages, etc. have produced methods and tools that improve the price/performance ratio of parallel software, and broaden the range of target applications. Alos, high level languages offer a high degree of abstraction which ease the development of complex systems. Moreover, being based on formal semantics, it is possible to certify the correctness of critical parts of the applications.

The PAPP workshop focuses on practical aspects of high-level parallel programming: design, implementation and optimization of high-level programming languages, semantics of parallel languages, formal verification, design or certification of libraries, middlewares and tools (performance predictors working on high-level parallel/grid source code, visualisations of abstract behaviour, automatic hotspot detectors, high-level GRID resource managers, compilers, automatic generators, etc.), application of proof assistants to parallel applications, applications in all fields of computational science, benchmarks and experiments. Research on high-level grid programming is particularly relevant as well as domain specific parallel software.

The aim of all these languages and tools is to improve and ease the development of applications (safety, expressivity, efficienty, etc.). Thus the Sixth PAPP workshop focuses on applications.

The PAPP workshop is aimed both at researchers involved in the development of high level approaches for parallel and grid computing and computational science researchers who are potential users of these languages and tools.


We welcome submission of original, unpublished papers in English on topics including:

All the contributions should illustrate the proposed techniques on a significant application.

Paper submission and publication

Prospective authors are invited to submit full papers in English presenting original research. Submitted papers must be unpublished and not submitted for publication elsewhere. Papers will go through a rigorous reviewing process. Each paper will be reviewed by at least three referees. The accepted papers will be published in the Springer-Verlag Lecture Notes in Computer Science (LNCS) series, as part of the ICCS proceedings.

Submission must be done through the ICCS website: here.

We invite you to submit a full paper of 10 pages formatted according to the rules of LNCS, describing new and original results, no later than January 5, 2009 (hard deadline). Submission implies the willingness of at least one of the authors to register and present the paper.

An early email to papp at with your intention to submit a paper would be greatly appreciated (especially if you have doubts about the relevance of your paper).

Accepted papers

Accepted papers should be presented at the workshop. Authors will be invited to submit extended and revised versions of their papers. Accepted manuscripts will be published in a special issue of Scalable Computing: Practice and Experience.
