<div class="moz-cite-prefix">Hi Federico<br>
<br>
have you been working with 6.3 stable version or with the develop
version(s) ? <br>
does the error occur with this system or also with other systems ?
<br>
what MPI library are you using ? <br>
have you tried to compile using the ELPA library ? <br>
<br>
sorry for replying with more questions and no answer <br>
Pietro <br>

<div>Both QE versions are compiled with INTEL 2018 on a Xeon
Gold 6128 based cluster linking MKL libraries</div>
<div>The error is reproduced on all the different nodes of the
cluster.</div>
<div><br>
</div>
<div>I check that the zhpev_drv.f90 routine, where the error
seems to come from, is in the<font face="monospace,

idea about the why and the how.</div>
<div>I am not convinced it is related to memory problem.</div>
<div><br>
</div>
<div>Is there anyone who can give me some hints?</div>
