For developers (GitHub)
Where the modules with '5.4.4' or '5.4.1' in their version strings are the builds of the pure MPI VASP codes, and the modules with '2018' or '2017' in their version strings are the builds of the hybrid MPI+OpenMP VASP codes, which are avaiblable to the NERSC VASP 5 users through the VASP.
The development of Wannier90 is managed on the Wannier developers GitHub site where you will find details of on-going developments, and how to contribute to Wannier90.

Electronic Structure Codes
Wannier90 should be used in conjunction with an electronic structure code for calculating the eigenstates of the Hamiltonian operator. Currently, as far as we are aware, the following electronic structure codes interface to Wannier90:
- Quantum ESPRESSO (PWscf) – stable versions of the interface to Wannier90 are available in the ‘pwscf’ directory of the distribution
- Wien2k – using the wien2wannier interface
- VASP – details can be found in the vasp manual
- GPAW – see this tutorial
- pySCF – using the pyWannier90 interface
Additional packages interfaced to Wannier90
- EPW – An open-source F90/MPI code which calculates properties related to the electron-phonon interaction using density-functional perturbation theory (DFPT) and maximally-localised Wannier functions.
- Gollum – A program written in Matlab that computes the electrical and thermal transport properties of multi-terminal nano-scale systems. The program can compute transport properties of either user-defined systems described by a tight-binding (or Huckel) Hamiltonian, or more material-specific properties of systems composed of real atoms described by DFT Hamiltonians.
- NanoTCAD ViDES – An open-source Python code for simulating nanoscale devices through the self-consistent solution of the Poisson and the Schrodinger equations by means of the non-equilibrium Green’s function (NEGF) formalism.
- Z2Pack – A tool for calculating topological invariants. The method is based on tracking the evolution of hybrid Wannier functions, which is equivalent to the computation of the Wilson loop.
- WannierTools – An open-source software package for novel topological materials.
- Sisl – An API for manipulating, constructing and creating tight-binding matrices in a standard and uniform way, which also provides an interface to the TBtrans code for large-scale NEGF transport calculations.
- WannierBerri is a Python code for Wannier interpolation and tight-binding calculations of bandstructure, Berry curvature, orbital moment, as well as evaluating the Brillouin zone integrals (e.g., anomalous Hall effect). It is an alternative to postw90.x and features performance improvements and additional functionality.
The following programs should be installed to visualise the output of Wannier90:
- gnuplot is used to plot band structures. It is available for many operating systems and is often installed on unix/Linux distributions by default
- XCrySDen is used to visualise crystal and molecular structures, Wannier functions and Fermi surfaces. It is available for Unix/Linux, Windows (using cygwin) and OSX. To correctly display files from Wannier90, use XCrySDen version 1.4 or later.
- VESTA is another program that can be used to visualise structures and Wannier functions, in particular when outputted in Gaussian cube format.
MLWFs and the LAPW formalism
Technical notes on the calculation of MLWF within the LAPW formalism are now available, courtesy of Prof. Michel Posternak [PDF].

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.
In VASP, central quantities, like the one-electron orbitals, the electronic charge density, and the local potential are expressed in plane wave basis sets. The interactions between the electrons and ions are described using norm-conserving or ultrasoft pseudopotentials, or the projector-augmented-wave method.
To determine the electronic groundstate, VASP makes use of efficient iterative matrix diagonalisation techniques, like the residual minimisation method with direct inversion of the iterative subspace (RMM-DIIS) or blocked Davidson algorithms. These are coupled to highly efficient Broyden and Pulay density mixing schemes to speed up the self-consistency cycle.
- VASP is available only to USF research groups that already have an existing VASP license.
Running VASP on CIRCE
The VASP user guide is essential to understanding the application and making the most of it. The guide and this page should help you to get started with your simulations. Please refer to the Documentation section for a link to the guide.
- Note on CIRCE: Make sure to run your jobs from your $WORK directory!
- Note: Scripts are provided as examples only. Your SLURM executables, tools, and options may vary from the example below. For help on submitting jobs to the queue, see our SLURM User’s Guide.
VASP runs reasonably well on most types of hardware but its performance depends greatly upon the number of atoms in the system, the k-point configuration specified in the KPOINTS file, and the number of ionic or relaxation steps you specify in INCAR. For smaller systems with a small set of atoms and k-point configuration, Gigabit Ethernet is sufficient for communications, but for anything more involved, you will definitely want to use Myrinet or InfiniBand for an interconnect.
Various VASP binaries are available for use, based on what you need to do.
Please Note: The VASP GPU binaries can only be accessed by using a separate module (apps/vasp/5.4.4_gpu). This module will conflict with other VASP modules, and must be loaded without any other VASP versions, complier, or cuda modules. Everything needed for running the VASP GPU executables will be loaded using the vasp/5.4.4_gpu module. Please review our GPU Guide for details about running GPU jobs on the cluster via SLURM.
