Abstract: The paper is devoted to the extended parallelization for numerical experiments in fluid dynamics and aeroacoustics on heterogeneous systems that combines computing units of different architectures, namely CPU and GPU. A hybrid two-level MPI+OpenMP parallel model is extended with OpenCL in order to engage GPUs. In doing so the third level of parallelism appears. A model of an algorithm for unstructured meshes is presented.

Keywords: CFD, computational aeroacoustics, parallel computing, MPI, OpenMP, GPU, OpenCL.
