<div dir="ltr">Okay thank you for the insight. I figured it was not a show stopper. Good to have the additional context regarding it being a change from the historical norm, and that it is associated with libxc which wasn't clear to me.</div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Sun, Nov 9, 2025 at 2:36 AM Pietro Davide Delugas <<a href="mailto:pdelugas@sissa.it">pdelugas@sissa.it</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<div dir="auto">No, at least not for what concerns correctness of the results.
<div dir="auto">With the new versions of libxc that test is regularly taking 35 iterations to converge instead of the 25 in the benchmark, but converges to the same ground state as in the benchmark. </div>

<div>Hello,</div>
<div><br>
</div>
<div>I am new to QE and I finally got v7.5 installed w/flags for libxc v7.0.0 </div>
<div>This is in a virtual machine Ubuntu 24.04.3 LTS</div>
<div>When I ran the QE self test it passed 251 out of 252 tests.</div>
<div><br>
</div>
<div>The only one that failed had the following console output.</div>
<div><br>
</div>
<div>pw_metaGGA - metaGGA-spin.in: **FAILED**.<br>
n1<br>
ERROR: absolute error 1.00e+01 greater than 8.00e+00. (Test: 25.0. Benchmark: 35.0.)</div>
<div><br>
</div>
<div>Is this cause for any concern? and if so is there any further diagnostics to pinpoint the root cause?</div>
<div>Sincerely,</div>
<div>Michael Dayan</div>
