-*NOTE:* The building process requires a working installation of a C++ and a FORTRAN compiler. Many solutions are available, but the recommended option is the *GNU Compiler Collection* `gcc` with the addition of `g++` and `gfortran`. The parallel code implementation further requires the use of parallel compilers complying with the MPI standard (*OpenMPI*, *MPICH*).

Many solutions are available, but the recommended option is the *GNU Compiler Collection* `gcc` with the addition of `g++` and `gfortran`. Single-workstation multi-threaded parallelism is supported through _OpenMP_, while the multi-node code implementation further requires the use of parallel compilers complying with the _MPI_ standard (_OpenMPI_, _MPICH_).
