Component-based design for adaptive large-scale infectious disease simulation

Component-based design improves productivity by concentrating development efforts on one component at a time without having to worry about a change having an application-wide effect. In this paper, we demonstrate the usefulness of componentbased approach in the development of an infectious disease simulator. Specifically, we have explored the possibility of self performance tuning at runtime through the use of hot-swappable components by incrementally develop optimised component variants easily. The application has achieved 4 times speedup using dynamic kernel adaptation and a further 5.3 times speedup through parallelisation on a multicore and GPU server.
