Abstract

Distributed parallel computing for a fluid-structure coupled simulation has been performed on a heterogeneous parallel computer cluster. The fluid and the structure dynamics are simulated on different parallel computers connected by a high-speed local network. These dynamics are coupled by a loose coupling method exchanging the boundary data between the fluid and the structure domains through the network. The data communication among parallel computers is realized by using the new communication library, Stampi, which has been developed to enable communication in a heterogeneous environment. The performance evaluation on a heterogeneous parallel computer cluster has shown that the distributed parallel computing for fluid-structure coupled simulations has the advantage of increasing the performance compared with the parallel computing on a single parallel computer.
