WebJun 4, 2024 · Another issue, I want to discuss is the performance of the DFTB code when compiled with both MAGMA and PLUMED libraries. (since GPU is not supported with MPI code, Plumed and DFTB are compiled without MPI support) It is much faster (depending on the system size) when MAGMA eigensolver is used compared to other solvers. WebThe DFTB module can treat molecular as well as periodic systems (1D for nanotubes, 2D for surfaces, 3D for bulk), and as such can be used as a fast pre-optimizer for full molecular and periodic DFT calculations with ADF and BAND. The DFTB license also includes the semi-empirical MOPAC library, which uses similar approximations and is ... can o worms review
