am working on improving properties of doped metal oxides. Installation of QE-GPU-5.4.0 was done without any errors then I am trying to optimize my structure (CeO2). After successfully submission of my calculations, either I am reaching to a stage with <b>oscillations of total energy </b>OR calculation automatically <b>stops without any error</b><b>.</b> I thought of it's because of BAD input parameters, so I changed so many parameters as suggested by so many users in pw_forum like mixing_bata, mixing_dim, smearing, dgauss and based on exchange correlation functional (NCPP, USPP) I changed ecutwfc and ecutrho also, but NO use.<br><br>After through search, I got a similar previous reported problem (it's very old): <a href="http://qe-forge.org/pipermail/pw_forum/2009-March/086558.html" target="_blank">http://qe-forge.org/pipermail/<wbr>pw_forum/2009-March/086558.<wbr>html</a> <br><br></div><div class="gmail_default" style="font-family:times new roman,serif">Same above input file (mine) I tried in 4 processor CPU (desktop) installed QE-5.4.0.
