The Vienna Ab initio Simulation Package (VASP) is an atomic scale materials modelling program for e.g. electronic structure calculations and quantum-mechanical molecular dynamics. Although the focus is on simulation of periodic structures like solids and surfaces, molecular structures can be simulated as well by the so-called supercell approach. VASP is a plane wave code using PAW (projector augmented wave) pseudopotentials. Exchange and correlation effects are described based on DFT (density functional theory) as well as Hartree-Fock and post Hartree-Fock methods.
Some features of VASP:
- Functionals: LDA, GGAs, metaGGAs, Hartree-Fock, Hartree-Fock/DFT hybrids
- Dynamics: Born-Oppenheimer molecular dynamics
- Relaxation: Conjugate gradient, quasi-Newton or damped molecular dynamics
- Transition state search: Nudged elastic band methods, climbing dimer method
- Linear response to electric fields: Static dielectric properties, Born effective charge tensors, piezoelectric tensors
- Green's function methods: GW quasiparticles
- Magnetism: Collinear and non-collinear, spin-orbit coupling
- Linear response to ionic displacements: Phonons, elastic constants, internal strain tensors

2 License and Citing
VASP is available only for groups with a valid group license. Furthermore every scientist has to be registered with his group VASP license at the VASP group in Vienna before we can grant access to the VASP binaries or pseudopotentials.
In future publications of work performed using VASP, the use of the software shall be properly acknowledged, e.g. in the form:
The calculations have been performed using the ab-initio total-energy and
molecular-dynamics program VASP (Vienna ab-initio simulation program)
developed at the Institut für Materialphysik of the Universität Wien [1,2].

If the PAW-version is used, an additional reference shell be made to:

3.1 Parallel computing and disk usage
Depending on the resources requested from the queueing system, the vasp script automatically detects whether to run the serial or the MPI-parallel version.
If running on multiple nodes, the job must run within a common job directory visible on all nodes. So in case of multi-node jobs, using /tmp/$USER is no option.
To lower the disk I/O demands of the VASP jobs one should add the options
LWAVE = .FALSE.; LCHARG = .FALSE.; LVTOT = .FALSE.
