Performance Analysis of CP2K Code for Ab Initio Molecular Dynamics

  title={Performance Analysis of CP2K Code for Ab Initio Molecular Dynamics},
  author={Dewi Yokelson and Nikolay V. Tkachenko and Robert W. Robey and Ying Wai Li and Pavel A. Dub},
Using a realistic molecular catalyst system, we conduct scaling studies of ab initio molecular dynamics simulations using the CP2K code on both Intel Xeon CPU and NVIDIA V100 GPU architectures. We explore using process placement and affinity to gain additional performance improvements. We also use statistical methods to understand performance changes in spite of the variability in runtime for each molecular dynamics timestep. We found ideal conditions for CPU runs included at least four MPI…

It is shown that the exact calculation of the electronic groundstate at each MD timestep is feasible using modern iterative matrix diagonalization algorithms and together with the use of ultrasoft pseudopotentials, ab initio MD simulations can be extended to open-shell transition metals with a high density of states at the Fermi-level.
Accurate and efficient linear scaling DFT calculations with universal applicability.
This work uses an ansatz based on localized support functions expressed in an underlying Daubechies wavelet basis to obtain an amazingly high accuracy and a universal applicability while still keeping the possibility of simulating large system with linear scaling walltimes requiring only a moderate demand of computing resources.
Gaussian basis sets for accurate calculations on molecular systems in gas and condensed phases.
A library of Gaussian basis sets that has been specifically optimized to perform accurate molecular calculations based on density functional theory and can be used in first principles molecular dynamics simulations and is well suited for linear scaling calculations.
Quickstep: Fast and accurate density functional calculations using a mixed Gaussian and plane waves approach
It is shown how derivatives of the GPW energy functional, namely ionic forces and the Kohn–Sham matrix, can be computed in a consistent way and the computational cost is scaling linearly with the system size, even for condensed phase systems of just a few tens of atoms.
PACKMOL: A package for building initial configurations for molecular dynamics simulations
This work has developed a code able to pack millions of atoms, grouped in arbitrarily complex molecules, inside a variety of three‐dimensional regions, which can be intersections of spheres, ellipses, cylinders, planes, or boxes.
