Strategic Optimization of Computation Nodes Allocation in a Coupled Simulation: Computational Fluid Dyanmics and Aero Acoustic Simulations

Computer simulations need a large amount of computational resources. We've believed that tightly-coupled computer is the first choice to perform the large scale simulations. This approach developing supercomputers never allows users to execute the interactive simulations so far. Here, a real time simulation indicates an interactive or streaming supercomputing, not batch queue one. The advantage of the streaming can be found when users execute coupled simulations combining a number of different simulations. To overcome the conventional batch queue supercomputing, we consider the effect of the characteristics of the internet. We proposed a strategic streaming supercomputing model to estimate total cost of the coupled simulation in widely distributed computing environment.
