WLPP 2013 is a full-day workshop to be held at the PPAM 2013 focusing on highlevel programming for large-scale parallel systems and multicore processors, with special emphasis on component architectures and models. Its goal is to bring together researchers working in the areas of applications, computational models, language design, compilers, system architecture, and programming tools to discuss new developments in programming Grids and parallel systems. The workshop focuses on any language-based programming model such as OpenMP, Intel TBB and Ct, Microsoft .NET 4.0 parallel extensions (TPL and PPL), Java parallel extensions, HPCS languages (Chapel, X10 and Fortress), Unified Parallel C (UPC), Co-Array FORTRAN (CAF) and GPGPU
language-based programming models such as CUDA. Contributions on other high-level programming models and supportive environments for parallel and distributed systems are equally welcome.

This workshop will feature papers that explore experiences from application developers in the use of the language and performance of real applications, experiences in the implementation of tools supporting the development and parallelization of applications or supporting the final execution on different computing platforms. We also welcome experiences in moving ideas and concepts from one programming model to another.

Possible topics include, but are not limited to,

* Language and library implementations.
* Proposals for, and evaluation of, language extensions.
* Applications development experiences.
* Comparisons between programming models.
* Benchmark Suites and performance studies.
* Debuggers and performance analysis tools.
* Compiler Implementation and Optimization.
* Optimization Techniques.
* Hybrid Models (OpenMP-MPI etc.)

Please submit full papers via the PPAM Conference submission system (formatted according to the PPAM specification), not previously published or submitted for publication elsewhere. Please acknowledge the workshop chair (address below) by sending an email include a cover page with the title, abstract, names and e-mail of the authors. Please submit pdf-files.
