HOW TO INSTALL THE GWL CODE

Introduction

The GWL code is released through the GPL-GNU license. It can be downloaded with the development version of the Quantum-Espresso through anonymous svn from here. At the moment the code has been tested with: ifort, g95,xlf95.

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 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
