sci-physics BigDFT is a package whose main program allows one to find the total energy, charge density and electronic structure of systems made of electrons and nuclei (molecules and periodic solids) within Density Functional Theory (DFT), using pseudopotentials and a wavelets basis. BigDFT-ABI is its fork by ABINIT developers to serve as a library for sci-physics/abinit. Enable support for nVidia CUDA Enable support for reading and writing the European Theoretical Spectroscopy facility (ETSF) file format. Enable support for OpenCL GPU acceleration.
