    Überblick zur Softwareentwicklung in Wissenschaftlichen Anwendungen

    Viele wissenschaftliche Disziplinen mĂŒssen heute immer komplexer werdende numerische Probleme lösen. Die KomplexitĂ€t der benutzten wissenschaftlichen Software steigt dabei kontinuierlich an. Diese KomplexitĂ€tssteigerung wird durch eine ganze Reihe sich Ă€ndernder Anforderungen verursacht: Die Betrachtung gekoppelter PhĂ€nomene gewinnt Aufmerksamkeit und gleichzeitig mĂŒssen neue Technologien wie das Grid-Computing oder neue Multiprozessorarchitekturen genutzt werden, um weiterhin in angemessener Zeit zu Berechnungsergebnissen zu kommen. Diese FĂŒlle an neuen Anforderungen kann nicht mehr von kleinen spezialisierten Wissenschaftlergruppen in Isolation bewĂ€ltigt werden. Die Entwicklung wissenschaftlicher Software muss vielmehr in interdisziplinĂ€ren Gruppen geschehen, was neue Herausforderungen in der Softwareentwicklung induziert. Ein Paradigmenwechsel zu einer stĂ€rkeren Separation von Verantwortlichkeiten innerhalb interdisziplinĂ€rer Entwicklergruppen ist bis jetzt in vielen FĂ€llen nur in AnsĂ€tzen erkennbar. Die Kopplung partitioniert durchgefĂŒhrter Simulationen physikalischer PhĂ€nomene ist ein wichtiges Beispiel fĂŒr softwaretechnisch herausfordernde Aufgaben im Gebiet des wissenschaftlichen Rechnens. In diesem Kontext modellieren verschiedene Simulationsprogramme unterschiedliche Teile eines komplexeren gekoppelten Systems. Die vorliegende Arbeit gibt einen Überblick ĂŒber Paradigmen, die darauf abzielen Softwareentwicklung fĂŒr Berechnungsprogramme verlĂ€sslicher und weniger abhĂ€ngig voneinander zu machen. Ein spezielles Augenmerk liegt auf der Entwicklung gekoppelter Simulationen.Fields of modern science and engineering are in need of solving more and more complex numerical problems. The complexity of scientiïŹc software thereby rises continuously. This growth is caused by a number of changing requirements. Coupled phenomena gain importance and new technologies like the computational Grid, graphical and heterogeneous multi-core processors have to be used to achieve high-performance. The amount of additional complexity can not be handled by small groups of specialised scientists. The interdiciplinary nature of scientiïŹc software thereby presents new challanges for software engineering. A paradigm shift towards a stronger separation of concerns becomes necessary in the development of future scientiïŹc software. The coupling of independently simulated physical phenomena is an important example for a software-engineering concern in the domain of computational science. In this context, different simulation-programs model only a part of a more complex coupled system. The present work gives overview on paradigms which aim at making software-development in computational sciences more reliable and less interdependent. A special focus is put on the development of coupled simulations
