Tutorials Using the pwscf Interface¶
The pwscf plane-wave, density-functional theory code,
which is available as part of the
quantum-espresso distribution
(http://www.quantum-espresso.org), is fully interfaced to
wannier90 via the pw2wannier90 post-processing code that is also
available as part of quantum-espresso.
Note that both the pwscf executable pw.x and pw2wannier90.x can
be run in parallel, which for large calculations can reduce the
computation time very significantly. This requires compiling the code in
its parallel version, using the MPI libraries. Refer to the
quantum-espresso package for the documentation on how to
do so.
Moreover we remind here that both the wannier90 executable and
postw90.x can be run in parallel. In this case any number of
processors can be used, independently of the number used for pw.x and
pw2wannier90.x.
