ELPH_USEBLAS = [logical]
Default: ELPH_USEBLAS = .TRUE.
Description: Toggles the use of BLAS routines for computing electron-phonon matrix elements.
| Mind: Available as of VASP 6.5.0 |
This is a performance setting that can offer a significant performance boost.
If ELPH_USEBLAS = True, then VASP uses BLAS routines when computing the electron-phonon matrix elements.
Otherwise, VASP-internal routines are used.
