NOISEtte is a parallel computing code based on high-order vertex-centered numerical schemes for unstructured meshes. It is designed for the computational fluid dynamics and aeroacoustics simulations using tens of thousands of CPU cores of a supercomputer. The underlying numerical methods and models including spatial discretization, time integration, turbulence models, and far-field acoustic models are briefly outlined. The program implementation issues are considered in details. A special attention is paid to the two-level MPI+OpenMP parallelization.

Keywords: fluid dynamics, aeroacoustics, aerodynamics, parallel computing, MPI, OpenMP
