ADF

Introduction

ADF (The Amsterdam Density Functional package) is a software for first-principles electronic structure calculations. It is particularly popular in the research areas of homogeneous and heterogeneous catalysis, inorganic chemistry, heavy element chemistry, various types of spectroscopy, and biochemistry.

BAND, also called ADF-BAND, is the name of a software package closely related to ADF. BAND can be used to study periodic systems: solids, surfaces, slabs, polymers, and reactions on surfaces. BAND is a part of ADF package here.

Running ADF on Graham

ADF 2016.106 and 2017.207 are installed on Graham cluster and available through the modules system. You can load them using either of.

[name@server $] module load adf/2016.106

[name@server $] module load adf/2017.207

Job Submission

Graham uses the Slurm scheduler; for details about submitting jobs, see Running jobs.

The following example is a full-node ADF job script, mysub.sh:

File : mysub.sh

#!/bin/bash
 #SBATCH --nodes=1 --ntasks-per-node=32  # 1 node with 32 cpus, you can modify it
 #SBATCH --mem-per-cpu=2G                # memory, should be <4G for full node job
 #SBATCH --time=00-03:00                 # time (DD-HH:MM)
 #SBATCH --output=adf_test.log           # output .log file

 module load adf/2017.207
 ADF adf_test.inp                # ADF command

The following is an example for the input file, adf_test.inp:

File : adf_test.inp

Examples

Examples for adf_test can be found on Graham under

/home/jemmyhu/tests/test_ADF/2017.207/test_adf/

Some user may do multi-step ADF runs within one job, see GO_H2O.run and GO_H2O.sh examples under

/home/jemmyhu/tests/test_ADF/2017.207/test_adf/

The same procedure applies to BAND job, see band_test.inp and band_test.sh examples under
