CP2K

CP2K is a quantum chemistry and solid state physics software package that can perform atomistic simulations of solid state, liquid, molecular, periodic, material, crystal, and biological systems. CP2K provides a general framework for different modeling methods such as DFT using the mixed Gaussian and plane waves approaches GPW and GAPW. Supported theory levels include DFT, MP2, RPA, GW, tight-binding (xTB, DFTB), semi-empirical methods (AM1, PM3, PM6, RM1, MNDO, …), and classical force fields (AMBER, CHARMM, …). CP2K can do simulations of molecular dynamics, metadynamics, Monte Carlo, Ehrenfest dynamics, vibrational analysis, core level spectroscopy, energy minimization, and transition state optimization using NEB or dimer method.

CP2K is written in Fortran 2008 and can be run efficiently in parallel using a combination of multi-threading, MPI, and GPU acceleration (CUDA for NVIDIA GPUs, HIP/ROCm for AMD GPUs, and OpenCL).

Downloading CP2K source code

For end users, the preferred method is to go to Releases and download and extract one of the versioned tarballs cp2k-X.Y.tar.bz2.

For developers, the preferred method is to fork the cp2k/cp2k repository and download via git clone. To clone the current master (development version):

git clone https://github.com/cp2k/cp2k.git cp2k

To clone a release version vx.y:

git clone -b support/vx.y --recursive https://github.com/cp2k/cp2k.git cp2k
