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