This work presents the newly developed three-dimensional parallel hydrodynamics code TraMP together with a generic C++ library for automatic parallelization of fi-nite difference schemes on structured grids. Furthermore we present two astrophysical applications, namely the problem of oscillating n-dimensional polytropes and exten-sive studies on the evolution of circumbinary disks including the accretion process and spectral distribution of the emitted energy. TraMP is based on the freely available POOMA library, which has been extensively extended and optimized for our needs. We were able to greatly improve parallel perfor-mance of the POOMA library by introducing native support for MPI and OpenMP. Ex-tensive performance measurements have shown that the parallel performance of TraMP scales up to 128 processors and more. The implemented infrastructure for Cartesian, cylindrical and spherical coordinate systems allows for easy covariant implementation of the finite difference schemes in TraMP. In the appendix an introduction to the POOMA library is given and the C++ techniques used by POOMA are briefly presented
