2. Cluster Setup

Goal

Prepare the cluster account so the combined gas-phase workflow can run cleanly.

Bash Setup

Use the provided setup script:

  • File: defualt_bashrc_setup.sh
  • Edit your cluster's bash configuration with:
vi ~/.bashrc
  • And edit and save using common terminal commands (i.e I, wq, ESC)

Home Directory Check

Make sure the following directories are present in your home directory (cd will that you to your home directory):

  • nearline
  • projects
  • scratch
  • vasp
  • virtenv

If missing flders continue below:

Virtual Environment

  • Create a virtual environment if virtenv is not already present.
python -m venv virtenv
  • Edit the virtual environment path here:
# Path to your virtual environment
export VENV_PATH="/home/your_path/virtenv"
export ASE_ENV="/home/your_path/virtenv/bin/activate"
  • Assume placeholder paths are correct in the tutorial examples and replace them only when adapting to your own account.

VASP Setup

Created vasp with mkdir and a vasp_PP sub-folder within vasp.

Expected structure:

~/vasp/
~/vasp/vasp_PP/

Then unzip:

tar -xf potpaw_PBE.64 1.tgz

Rename the extracted folder to:

  • potpaw_PBE

Notes

  • The combined workflow uses one SLURM submission per molecule.
