<div dir="ltr">Dear All,<br><br>When I perform the scf calculation with high kp (45 45 45) and cut-off (42 Ry), the parallel execution ph.x fails and stops (q-points in <a href="http://ph.in">ph.in</a>: 4 4 3). but lowering the kp (15 15 15) and cut-off (22 Ry) solves the problem and the parallel ph.x goes on without any problem. Does this mean that I can not calculate phonon spectra with this accuracy?<br>
Also, the calculations are for metals.<br><br><br>> Dear PWscf users,<br>
><br>
> I have encountered a problem during parallel execution of ph,x<br>
><br>
> Actually the parallel pw,x performs good and without any error, but ph.x does not work,<br>
> I lowered the kpoints and kinetic-energy cut-off and the problem solved and ph.x works properly.<br>
> I need high accuracy in my calculation, so I cannot lower the kpoints and cut-off.<br>
> How can I perform parallel ph.x without lowering the computational parameters?<br>
><br>
> Any help would be appreciated.<br>
> Thanks.<br>
