    Dear Yin Li,<br>
    we do not have your computers so we cannnto reproduce your problem.
    What we could do is that you pay to us all a trip to Budapest, to
    have a look. Or you could just provide the output files.<br>
    <br>
    kind regards<br>

      <div>I found a strange behavior of my installed QE 5.1.1. </div>
      <div>I compiled Quantum Espresso 5.1.1 using the same compiler
        with the same library on the same OS (Ubuntu 14.04).  I just run
        the same input file on different computers. However, I got
        different output files. One could achieve convergence, another
        could not.  Which result is more reliable?</div>
      <div>Here is my input file.</div>
