CP2K is an open-source software package for performing atomistic simulations including electronic structure calculations using DFT and (post) Hartree-Fock (HF) methods as well as MD simulations using classical force fields. CP2K uses analytic Gaussian-type orbitals to form a local basis set, which can be used to simulate both periodic and non-periodic systems. Additional unique features include the auxiliary density matrix method (ADMM) for accelerating hybrid DFT calculations, the Gaussian and Augmented Plane Waves (GAPW) method for scalable all-electron calculations, and linear scaling DFT methods. Basic DFT tasks with CP2K have been interfaced with atomate2 using jobflow.
