<body class='hmmessage'><div dir='ltr'>Dear All,<div><br></div><div>Here is my problem. I can calculate the silicon band structure example given in the tutorials (one of pwscf examples) by using my desktop computer with no problem. However when I use the cluster in the campus, I can not get the bands.x run properly. It always gives the following error message in the bands.out file. (see below) I changed it to &bands and run it again. The output file looks the same. I look through the bands.f90 file and the error originates from a subroutine mp_bcast. The variable ios (I have no idea what it actually corresponds) has to be zero to avoid error message, if I read this correctly. </div><div><br></div><div>By the way a similar program dos.x works very well in the same cluster. </div><div><br></div><div>Thanks </div><div><br></div><div><div>  2      Program BANDS v.5.0.2 (svn rev. 9392) starts on 25Sep2013 at 10:57:34</div><div>  3 </div><div>  4      This program is part of the open-source Quantum ESPRESSO suite</div><div>  5      for quantum simulation of materials; please cite</div><div>  6          "P. Giannozzi et al., J. Phys.:Condens. Matter 21 395502 (2009);</div><div>  7           URL http://www.quantum-espresso.org",</div><div>  8      in publications or presentations arising from this work. More details at</div><div>  9      http://www.quantum-espresso.org/quote.php</div><div> 10 </div><div> 11      Parallel version (MPI), running on     8 processors</div><div> 12      R & G space division:  proc/nbgrp/npool/nimage =       8</div><div> 13 *** namelist &inputpp no longer valid: please use &bands instead</div><div> 14 </div><div> 15 </div><div> 16  %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%</div><div> 17 </div><div> 18  %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%</div><div> 19      Error in routine bands (17):</div><div> 20      reading bands namelist</div><div> 21  %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%</div><div> 22  %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%</div><div> 23      Error in routine bands (17):</div><div> 24      reading bands namelist</div><div> 25  %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%</div><div> 26 </div><div> 27      stopping ...</div><div> 28      Error in routine bands (17):</div><div> 29      reading bands namelist</div><div> 30  %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%</div><div> 31 </div><div> 32      stopping ...</div><div> 33 </div><div> 34  %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%</div><div> 35      Error in routine bands (17):</div><div> 36      reading bands namelist</div><div> 37  %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%</div><div> 38 </div><div> 39      stopping ...</div><div> 40 </div><div> 41  %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%</div><div> 42      Error in routine bands (17):</div><div> 43      reading bands namelist</div><div> 44  %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%</div><div> 45 </div><div> 46      stopping ...</div><div> 47 </div><div> 48  %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%</div><div> 49      Error in routine bands (17):</div><div> 50      reading bands namelist</div><div> 51  %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%</div><div> 52 </div><div> 53      stopping ...</div><div> 54 </div><div> 55      stopping ...</div></div><div><br></div>                                       </div></body>
