Description
Dalton (named after John Dalton) is an ab initio quantum chemistry computer program designed to to allow convenient, automated determination of a large number of molecular properties based on an HF, HF-srDFT, DFT, MP2, CC, CI, MCSCF, or MC-srDFT reference wave function. For additional information on features please visit the Description of the Dalton suite features web page.
Availability
Dalton is available on selected bwHPC-Clusters. A complete list of versions currently installed on the bwHPC-Clusters can be obtained from the Cluster Information System (CIS).
In order to check which versions of Dalton are installed on the compute cluster, run the following command:
$ module avail chem/dalton
License
Dalton is free, open-source software released under the GNU Lesser General Public License (LGPL). Anyone interested in using the Dalton program suite must read the conditions described in its license agreement.
Usage
Loading the module
You can load the default version of Dalton with the command:
$ module load chem/dalton
The module will try to load modules it needs to function (e.g. compiler, mpi, numlibs). If loading the module fails, check if you have already loaded one of those modules, but not in the version needed for Dalton. If you wish to load a specific (older) version (if available), you can do so using e.g. 'module load chem/dalton/version' to load the version you desires.
$ module avail chem/dalton ------------------------ /opt/bwhpc/common/modulefiles ------------------------- chem/dalton/2013 $ module load chem/dalton/2013
Program Binaries
You can find the Dalton binaries in the main folder of the Dalton system.
After loading the Dalton module ('module load chem/dalton/version') it's path is
also set to the local $PATH- and $DALTON_BIN_DIR environments.
$DALTON_BIN_DIR=/opt/bwhpc/common/chem/
$ : Example with Dalton 2013 $ echo $DALTON_BIN_DIR /opt/bwhpc/common/chem/dalton/2013/bin $ ls -F $DALTON_BIN_DIR basis/ DALTON.STAT GIT_HASH lsdalton.x* tools/ dalton* dalton.x* lsdalton* lslib_tester.x* VERSION
- A '/' at the end of a file name indicates a directory/folder.
- '*' is an executable file.
Disk Usage
Scratch files are written to the current directory by default. Please change to a local directory or to your local workspace (preferred) before starting your calculations.
'dalton_repo' is an example name of a repository you created by using the command 'ws_allocate'.
$ cd $(ws_find dalton_repo) ['your-id'-dalton_repo-0]$ pwd /work/workspace/scratch/'your-id'-dalton_repo-0 ['your-id'-dalton_repo-0]$
Examples
bwHPC examples
You can copy a simple interactive example to your workspace and run it, using 'msub'
$ cd $(ws_find dalton_repo) $ cp $DALTON_EXA_DIR/bwunicluster-dalton-example.moab . $ cp bwunicluster-dalton-example.moab mydaltonjob.moab § vi mydaltonjob.moab # do your own modifications $ msub mydaltonjob.moab # start job submission
It is strongly recommended to use $DALTON_EXA_DIR to find the bwHPC examples.
