Lectures

• DFT, PW, and PAW: "VASP: The basics(1). DFT, plane waves, PAW, ...".

• electronic convergence, BZ sampling: "VASP: The basics(2). electronic convergence, BZ sampling ...".

• Hybrid functionals: "VASP: Hybrid functionals".

• Dielectric properties: "VASP: Dielectric response. Perturbation theory, linear response, and finite electric fields".

• Performance: "VASP: running on HPC resources".

Environment Setup

After login, open a Terminal and enter following command

source ~/data/bin/setup_environment.sh 

The job scripts found in the tutorial files (job.sh, doall.sh, etc) work only if the environment variables "vasp_std, vasp_gam, vasp_ncl" are defined. This is done via

export vasp_std="mpirun -np 2 /home/notebook/data/bin/vasp_std"
export vasp_gam="mpirun -np 2 /home/notebook/data/bin/vasp_gam"
export vasp_ncl="mpirun -np 2 /home/notebook/data/bin/vasp_ncl"
