VASP¶
VASP Status¶
VASP: The Vienna Ab initio Simulation Package version 6.2.0 is operational with OpenACC GPU support on the HPC for the Standard, Gamma Ponit and Non-Collinear versions.
VASP Overview¶
From 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.
VAPS Quickstart Command Line Guide¶
VASP Quickstart Command Line Guide¶
VASP must be started via the MPI wrapper script. If your SLURM Script has requested a GPU, VASP will autodetect and use the GPU for all supported operations. Substitute the VASP binary of your requirements.
