This paper outlines the distribution of an aeroacoustic application in a heterogeneous super computing environment. PACX-MPI, which is used for this distribution allows the coupling of different architectures without leaving the MPI context in the application itself. This makes the usage of a heterogeneous infrastructure very convenient from the applications point of view.Integrated simulation of fluid flow with its aeroacoustic is a typical multi-scale task with different numerical requirements in the involved parts. The different requirements can be spatially separated as the noise generating object is generally rather small when compared to the area which is to be computed for the sound propagation. A natural division into a domain of noise generation and a domain of noise propagation arises and the two different computational domains are only loosely coupled with numerical requirements very distinct from each other. We demonstrate how the parallel simulation of a 3D aeroacoustic testcase can benefit of the heterogeneity in the infrastructure by mapping the heterogeneous computational domain on the appropriate architectures.
