CPMD added to alphabetical listing

I’ve added CPMD to the alphabetical listing of applications.

CPMD is an ab initio electronic structure and molecular dynamics (MD) program using a plane wave/pseudopotential implementation of density functional theory (DFT). It is mainly targeted at Car-Parrinello MD simulations, but also supports geometry optimizations, Born-Oppenheimer MD, path integral MD, response functions, QM/MM, excited states and calculation of some electronic properties.

Full installation instructions are available on the website together with the user manual and examples.

The examples can run effectively on an Intel Core i5 (2.53 GHz, OS/X) with 4 GB of available memory (most of tests require ca. 1GB, few more). Nonetheless, references have been generated on an IBM Blade power7 (with 8 mpi tasks and 1 OMP task per CPMD run) with 64 GB of available memory. Estimates of the execution time and memory requirements will be given based on this more performant setup.

CPMD capabilities

  • Works with norm conserving or ultrasoft pseudopotentials
  • LDA, LSD and the most popular gradient correction schemes; free energy density functional implementation
  • Isolated systems and system with periodic boundary conditions; k-points
  • Molecular and crystal symmetry
  • Wavefunction optimization: direct minimization and diagonalization
  • Geometry optimization: local optimization and simulated annealing
  • Molecular dynamics: constant energy, constant temperature and constant pressure
  • Path integral MD
  • Response functions
  • Excited states
  • Many electronic properties
  • Time-dependent DFT (excitations, molecular dynamics in excited states)
  • Coarse-grained non-Markovian metadynamics

CPMD is free for non-profit organisations.
