Dalton

Introduction

Le noyau de la suite logicielle Dalton2016 est constitué de deux puissantes applications pour l'étude des structures électroniques de molécules : Dalton et LSDalton. Ensemble, ces applications offrent des fonctionnalités étendues pour le calcul des propriétés moléculaires aux niveaux théoriques HF, DFT, MCSCF et CC. Plusieurs de ses propriétés sont uniques à la suite Dalton2016.

Modules

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

Remarquez que dalton/2017-alpha dépend d’une version OpenMPI autre que la version par défaut. Pour de l’information sur la commande module voyez Utiliser des modules.

Utilisation

Voici un exemple ː

• Dalton input file: dft_rspexci_nosym.dal (see Examples below)
• Molecule specification: H2O_cc-pVDZ_nosym.mol (see Examples below)
• To use the atomic basis set installed with the program, supply the option -b ${BASLIB}.
• 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
