High Performance Computing plays an important role for numerical simulation and modelling in computational science as well as academic and industrial research. At the same time, using large-scale parallel systems efficiently is also becoming more difficult.  A number of tools addressing parallel program development and analysis have emerged in the High Performance Computing community over the last decade. They may have started as collection of small helper script, but in the meantime matured to production grade frameworks. Powerful user interfaces and a rich body of documentation allows easy usage by non-specialist. In fact, some of the tools have been commercialized, while others are driven as open source by a broadening research community.

This book represents the proceedings of the 15th International Parallel Tools Workshop, held in Dresden, Germany, September 19-20, 2024 - which is a forum to discuss the latest advances in parallel tools.
