Abstract
Using software for large-scale simulations has become an important research
method in many disciplines. With increasingly complex simulations, simulation
software becomes a valuable assest. Yet, the quality of many simulation codes
is worrying. In this paper, we want to collect and structure the challenges for
a systematic simulation software engineering as a reference and the basis for
further research. We describe our own experiences with developing simulation
software and collaborating with non-computer-scientists. We complement our
experienced challenges with a brief literature review. We structured the
challenges for simulation software engineering into six areas: motivation and
recognition; education and training; developer turnover; software length of
life; verification, validation and debugging; and efficiency vs.
maintainability. Overcoming these challenges needs efforts from research
agencies, scientific computing researchers as well as software engineering
researchers.
