 The purpose of the CP2K benchmark suite is to provide performance which can be used to guide users towards the best configuration (e.g. machine, number of MPI processors, number of OpenMP threads) for a particular problem, and give a good estimation for the parallel performance of the code for different types of method. Five benchmarks are provided: ''H2O-64'', ''Fayalite-FIST'', ''LiH-HFX'', ''H2O-DFT-LS'' and ''H2O-64-RI-MP2''. Descriptions of each benchmark along with performance figures are below. The purpose of the CP2K benchmark suite is to provide performance which can be used to guide users towards the best configuration (e.g. machine, number of MPI processors, number of OpenMP threads) for a particular problem, and give a good estimation for the parallel performance of the code for different types of method.

-//Ab-initio// molecular dynamics of liquid water using the Born-Oppenheimer approach, using [[Quickstep]] DFT. Production quality settings for the basis sets (TZV2P) and the planewave cutoff (280 Ry) are chosen, and the Local Density Approximation (LDA) is used for the calculation of the Exchange-Correlation energy.  The configurations were generated by classical equilibration, and the initial guess of the electronic density is made based on Atomic Orbitals.  The system contains 64 water molecules (192 atoms, 512 electrons) in a 12.4 Å<sup>3</sup> cell.+//Ab-initio// molecular dynamics of liquid water using the Born-Oppenheimer approach, using [[Quickstep]] DFT.
