The kernel of the Dalton2016 suite is the two powerful molecular electronic structure programs, Dalton and LSDalton. Together, the two programs provide an extensive functionality for the calculations of molecular properties at the HF, DFT, MCSCF, and CC levels of theory. Many of these properties are only available in the Dalton2016 suite.

Introduction[edit]

The kernel of the Dalton2016 suite is the two powerful molecular electronic structure programs, Dalton and LSDalton. Together, the two programs provide extensive functionality for the calculations of molecular properties at the HF, DFT, MCSCF, and CC levels of theory. Many of these properties are only available in the Dalton2016 suite.

Modules[edit]

$ module load nixpkgs/16.09 intel/2016.4 openmpi/2.0.2 dalton/2017-alpha

Notice that dalton/2017-alpha depends on a non-default version of Open MPI. For more on the module command see Using modules.

Usage[edit]

Here is an example:

  • Dalton input file: dft_rspexci_nosym.dal (see the examples below).
  • Molecule specification: H2O_cc-pVDZ_nosym.mol (see the examples below).
  • To use the atomic basis set installed with the program, supply option -b ${BASLIB} to the command line (see the examples below).
  • The number of processes can be set using a command line option or an environment variable:
    • Add the option -N ${SLURM_NTASKS} to the launcher command line (refer to Script 1 in the examples below);
    • or, export DALTON_NUM_MPI_PROCS=${SLURM_NTASKS} (refer to Script 2 in the examples below).

To run Dalton, load the module and use the launcher dalton: 

dalton -b ${BASLIB} -N ${SLURM_NTASKS}  -dal dft_rspexci_nosym.dal  -mol H2O_cc-pVDZ_nosym.mol

or 

export DALTON_NUM_MPI_PROCS=${SLURM_NTASKS}
dalton -b ${BASLIB}  -dal dft_rspexci_nosym.dal  -mol H2O_cc-pVDZ_nosym.mol
