What is CP2K?

CP2K is a quantum chemistry and solid state physics software packages that can perform atomistic simulations of solid state, liquid, molecular, periodic, material, crystal and biological systems. It is especially aimed at massively parallel and linear scaling electronic structure methods and state-of-the-art ab-initio molecular dynamics (AIMD) simulations.

CP2K is optimized for the mixed Gaussian and Plane-Waves (GPW) method based on pseudopotentials, but is able to run all-electron or pure plane-wave/Gaussian calculations as well.

Using CP2K at HPC system

CP2K includes support for:

  • libint : Hartree-Fock exchange
  • libxc : Exchange-correlation functionals for density-functional theory

To load the CP2K and the corresponding modules:

System CP2K version Compiler Command
HPC2021 2022.1 GCC 10.2 module load cp2k/2022.1

Both serial optimized and parallelized MPI/OpenMP version of CP2K are available in the cluster system.

CP2K binaries:

  • cp2k.sopt – Serial, Optimized
  • cp2k.ssmp – Single node + Multithreading (OpenMP)
  • cp2k.popt – Parallel (MPI), Optimized
  • cp2k.psmp – Parallel (MPI) + Multithreading (OpenMP)

How to run CP2K?

Basic command: cp2k.sopt -i [input_file] -o [output_file]

We prepared some sample input file and SLURM scripts for CP2K at /share1/cp2k/sample/. User can copy the files and modify for your use.
