What is VASP?

The Vienna Ab initio Simulation Package (VASP) is a computer program for atomic scale materials modelling, e.g. electronic structure calculations and quantum-mechanical molecular dynamics, from first principles.

VASP computes an approximate solution to the many-body Schrödinger equation, either within density functional theory (DFT), solving the Kohn-Sham equations, or within the Hartree-Fock (HF) approximation, solving the Roothaan equations. Hybrid functionals that mix the Hartree-Fock approach with density functional theory are implemented as well. Furthermore, Green’s functions methods (GW quasiparticles, and ACFDT-RPA) and many-body perturbation theory (2nd-order Møller-Plesset) are available in VASP.

Permission of using VASP

VASP is an licensed software which is available for research groups with valid VASP licenses. Proof of a license is required before being granted access to VASP on our systems. If your group have a valid academic VASP license, please ask your group leader/license holder to register your account under his VASP-group member via VASP Portal (or contact Materials Design if purchased via Materials Design Inc.). ITS will validate with VASP/Materials Design to confirm you are authorised to use VASP in our facilities. Upon confirmation from VASP, we will grant the access.

The license of VASP only grant access to a limited number of users in your research group. The license holder are responsible to maintain the list for any changes (e.g. student graduation, personnel change).

If you have a license for 4.6 version but you would like to access the 5.x versions, you must upgrade your license.

Authorized user will be assigned in the group of “vasp4”, “vasp5” and/or “vasp6” according to the license version. Otherwise you will not have permission to run VASP. You may check your group membership with command “groups“:

$ groups
$ student vasp5

Using VASP in HPC system

To setup required environment variables for VASP, please use following command:

System VASP version Release Command
HPC2015 VASP 4 4.6 module load vasp4/impi/4.6
VASP 5 5.3 module load vasp5/impi/5.3
5.4.1 module load vasp5/impi/5.4.1
5.4.4 module load vasp5/impi/5.4.4
VASP 6 6.1.2 module load vasp6/impi/6.1.2
HPC2021 VASP 5 5.4.4 module load vasp5/5.4.4
VASP 6 6.2.0 module load vasp6/6.2.0
6.2.1 module load vasp6/6.2.1

(A) Prepare input files

Prepare input files (i.e. INCAR, KPOINTS, POSCAR, POTCAR and so on).

(B) Naming of VASP Executable files

Name Version Description
vasp_std Standard Compiled with -DNGZhalf
vasp_gam Gamma-only Compiled with -DNGZhalf and -DwNGZhalf. Optimized for gamma-point calculations, faster but allow calculations at gamma-point only.
vasp_ncl Non-collinear Compiled without -DNGZ*. For non-collinear/spin-orbit coupling calculations. It uses more memory than the other versions.
vasp_gpu_std Standard (GPU-enabled) Standard version accelerated with GPU. (support after VASP 5.4.1)
vasp_gpu_ncl Non-collinear (GPU-enabled) Non-collinear version accelerated with GPU. (support after VASP 5.4.1)

(C) Submit batch job

Sample of input files and PBS command file are available in /share1/vasp/sample/. Explanation is embedded in these files. You may modify it upon your requirements(e.g. vasp_std/vasp_gam/vasp_ncl, number of nodes)

To submit a job, copy the sample PBS/SLURM command file to directory where input files exists and then type:

HPC2015 qsub -q [queue_name] pbs-vasp.cmd
HPC2021 sbatch slurm-vasp.cmd
