Working setup and testing setups

This section describes the current working setup based under the condition that the installation is successful and a model run is starting for a given time stamp of input data. Unstable means that for the current namelist-files some model runs end preliminary with an error. The different setups will be categorized in

{compiling, not_compiling}
{debug_build, normal_build, hybrid_build, combined_build}
{stable, running, unstable, not_running}

All setups for WRFV3.x use gcc/gcc-libs/gcc-gfortran 6.3.1-2 until described otherwise. WRFV4 uses the latest version of gcc/gcc-gfortran: 9.x.x.

current setup:
- WRF Model and WPS v4.0.2 [compiling, normal_build, running]
  - NetCDF v4.6.1 / NetCDF-Fortran Library v4.4.5
  - mpi v3.3, libpng v1.6.36, zlib v1.2.11, JasPer v1.900.2
testing setup:
- preparing WRF Model and WPS v4.1
tested setups:
- WRF Model and WPS v3.8.1 [compiling, normal_build, unstable]
  - NetCDF v4.4.1.1 / NetCDF-Fortran Library v4.4.4
  - mpi v3.2, libpng v1.6.34, zlib v1.2.11, JasPer v1.900.2
- WRF Model and WPS v3.9 [compiling, normal_build, unstable]
  - NetCDF v4.5.0 / NetCDF-Fortran Library v4.4.4
  - mpi v3.2.1, libpng v1.6.34, zlib v1.2.11, JasPer v1.900.1
