Description

From the NERSC website: SIESTA is an O (N) DFT code for electronic structure calculations and ab initio molecular dynamics simulations for molecules and solids. It uses norm-conserving pseudopotentials and linear combination of numerical atomic orbitals (LCAO) basis set.

Version

  • 3.1

Authorized Users

  • CIRCE account holders
  • RRA account holders
  • SC account holders

Platforms

  • CIRCE cluster
  • RRA cluster
  • SC cluster

Modules

SIESTA requires the following module file to run:

  • apps/siesta/3.1

Running SIESTA Jobs on CIRCE

The SIESTA user guide is essential to understanding the application and making the most of it. The guide and this page should help you to get started with your simulations. Please refer to the Documentation section for a link to the guide.

  • Note on CIRCE: Make sure to run your jobs from your $WORK directory!
  • Note: Scripts are provided as examples only. Your SLURM executables, tools, and options may vary from the example below. For help on submitting jobs to the queue, see our SLURM User’s Guide.

Submitting Jobs

If, for example, you have an SIESTA input file named input.in, you would set up a submit script like this:

The script below (for testing, name it “siesta-test.sh”) can be copied into your job directory (the folder with your input files) and modified so that you can submit batch processes to the queue.

#!/bin/bash
#
#SBATCH --comment=siesta-test
#SBATCH --ntasks=4
#SBATCH --job-name=siesta-test
#SBATCH --output=output.%j.siesta-test
#SBATCH --time=01:00:00

#### SLURM 4 processor SIESTA test to run for 1 hour.

module purge
module load apps/siesta/3.1

mpirun siesta < input.in

 
Next, you can change to your job’s directory, and run the sbatch command to submit the job:

[user@login0 ~]$ cd my/jobdir
[user@login0 jobdir]$ sbatch ./siesta-test.sh
  • You can view the status of your job with the “squeue -u <username>” command
