An Aspect-Oriented Approach for Disaster Prevention Simulation Workflows on Supercomputers, Clusters, and Grids

Computer simulation is an important factor in today's disaster prevention procedures. Simulation codes assess the evolution and impact of various physical phenomena in domains such as nuclear and environmental sciences, and ultimately help saving lives. However, new and more computationally demanding models, and new regulations for personnel training have increased the demand for computational power. While the existing simulation codes can be ported to computing environments that can meet the new demand, such as supercomputers, clusters, and grids, it is too expensive and time-consuming to rewrite and re-certify them. Instead, in this work we propose an aspect-oriented approach that takes existing simulation functionality and combines it with functionality required to run the simulation on different computing environments transparently to the simulation developer. Through experiments in the DAS-3 multi-cluster grid we show that our approach increases the reusability, the maintaina...
