Special Track: Performance and Software Engineering in Scientific Computing at the Workshop on Parallel and Distributed Scientific and Engineering Computing (PDSEC’19)

Developers of simulation codes in scientific computing are mostly domain experts, but not experts in computer science. Hence, existing as well as newly developed codes routinely offer opportunities for improvements, regarding performance as well as software engineering. On the other hand, the main focus for application developers with a general computer science background is on usability as well as maintenance and readability. This often leads to conflicts of interests when scientific application developers and computer scientists work together.

Since parallel computing architectures are pervasive, the actual performance of these codes on parallel systems is important for both scientific competitiveness as well as efficient usage. Additionally, codes developed in research undergo continuous changes and are used on different computing systems, which necessitate the development and maintenance of frameworks for software infrastructure to keep the code usable over the years and across the changing computing system structures. Such code maintenance needs to address code restructuring and refactoring for performance and usability of the code. Thus this is a recurring process throughout the software life.

This special track at the PDSEC workshop focuses on performance engineering and software structure maintenance for codes in the scientific research area, in particular in the field of engineering. Our aim is to bring together code developers from the engineering field with HPC- and software experts. Submitted talks should cover at least one of the following topics:

  • Results and challenges from the application of performance analysis tools on computational codes in the engineering field.
  • Practice and success stories of performance improvements, with additional code description or method changes.
  • Experience, using special frameworks for software infrastructure maintenance, especially when using open source codes.
  • Best-practice results on scientific code lifecycle management.
