CALL FOR CONTRIBUTIONS 7th Workshop on PARALLEL/HIGH-PERFORMANCE OBJECT-ORIENTED SCIENTIFIC COMPUTING (POOSC'08) at the EUROPEAN CONFERENCE ON OBJECT-ORIENTED PROGRAMMING (ECOOP 2008) Paphos, Cyprus, 7-11 July 2008 http://www.ccs3.lanl.gov/poosc08/ While object-oriented programming is being embraced in industry, particularly in the form of C++ and to an increasing extent Java and Python, its acceptance by the parallel scientific programming community is still tentative. In this latter domain performance is invariably of paramount importance, where even C++ is considered suspect, primarily because of real or perceived loss of performance. On the other hand, various factors practically dictate the use of language features that provide higher level abstractions than do C or older FORTRAN standards. These include increasingly complex physics models, numerical algorithms, and hardware--deep memory hierarchies, exponentially-increasing numbers of processors, and the advent of multi- and many-core processors and heterogeneous architectures. This workshop seeks to bring together practitioners and researchers in this growing field to `compare notes' on their work. The emphasis is on identifying specific problems impeding greater acceptance and widespread use of object-oriented programming in scientific computing; proposed and implemented solutions to these problems; and new or novel approaches, techniques or idioms for scientific and/or parallel computing. Presentations of work in progress are welcome. Specific areas of interest include, but are not limited to: * tried or proposed programming language alternatives to C++; * performance issues and their realized or proposed resolution; * issues specific to handling or abstracting parallelism, including the handling or abstraction of heterogeneous architectures; * specific points of concern for progress and acceptance of object-oriented scientific computing; * existing, developing, or proposed software; * frameworks and tools for scientific object-oriented computing; * schemes for user-level fault tolerance; * grand visions (of relevance). The workshop will consist of a sequences of presentations each followed by a discussion session. The workshop will conclude with an overall discussion. We expect the majority of the participants to give presentations. For authors of accepted presentations who require justification for travel the organizers can provide official letters of invitation. PUBLICATION Full papers accepted to the workshop will be published as a proceedings either in the Springer LNCS series or in the John von Neumann Institute for Computing NIC series, Forschungszentrum Juelich. Additionally, it is possible that a summary of the workshop will be published as an ECOOP Workshop Reader in Springer's LNCS series. SUBMISSION PROCEDURE Prospective authors are invited to submit abstracts, papers, or presentations (slides) in ASCII, PDF, postscript, or PowerPoint. Submitted materials will be distributed at the workshop.
