HOW TO INSTALL THE GWL CODE

Introduction

The GWL code is released within the Quantum-Espresso. For the latest features and patches it is worth installing the development version.

Steps for installing

  1. Download install and compile the pw.x and the ph.x codes of the QE
  2. Go to the main QE directory
  3. Type: make gwl

Note

Some VERY old versions of the intel mkl package contain a bug in the lapack DSYEVR routine. A workaround to avoid the calling of this routine is:
replace pmat_type=4 with pmat_type=3 in the input files for the pw4gww.x code.
replace l_dsyevr=.true. with l_dsyevr=.false. in the following files of the pw4gww directory: fake_conduction.f90,pola_lanczos.f90,self_lanczos.f90
