<p>Dear all!</p>
<p><br>
</p>
<p>I am trying to use HSE to correct the band-gap (YAMBO has turned out quite memory heavy for this system) and I am running in some problems on QE 6.1 on the cluste (but not older version QE 5.x on my local machine) which seems to be related to the new ACE
algorithm for handling the exchange part; the error message is </p>
<p><br>
</p>

<pre style="font-family:courier,"courier new",monospace;font-size:14px;white-space:pre-wrap;word-wrap:break-word;margin-top:0px;margin-bottom:0px">task # 2 from DPOTRF : error # 1 Cholesky failed in
aceupdate. </pre>
<br>
<p></p>
<p>the exactly same input works without problems in the old QE versions where ACE was not the default, I believe (according to <span>T.A. Barnes et al. / Computer Physics Communications 214 (2017) 52–58 )</span>. So here is my simple question:</p>
<p><br>
</p>
<p>can I turn ace off?</p>
<p><br>
</p>
<p>I know there is a variable "use_ace" but I wanted to ask here before I break something...</p>

<div>* Hybrid functionals: ACE is now the default for scf calculations (it wasn't<br>
in 6.1 contrary to what previously stated in this file); it is disabled<br>
for TD-DFPT. See variable "use_ace".</div>

<p>Thanks in advance for your time and help!</p>
