In recent years, there was a tendency towards heterogeneous systems. Themain property of these systems is that communication resources and computationresources are non-uniform in architecture and performance. Often,communication links between physically close infrastructure nodes provide highperformance, e.g. in the sense of low latency or high bandwidth. A placementmethodology for such systems should minimise the overall communication costsand prevent blocking of long, low-performanced communication links. Thereforeapplication components with higher communication demands should be locatedcloser to each other. For this, we propose a placement methodology that isbased on a hierarchical application and infrastructure description. Due to ourhierarchical approach, no knowledge about the potentially complex semantics ofmulti-dimensional communication demands is needed for the optimisationduring the run-time of the placement. Our implementation shows a simple butefficient online-placement which also leads to a higher robustness in distributedembedded systems.
