Dear All,<div><br></div><div>I am performing a geometry optimization of a Au cluster by 1 node, 96 core, using PBE and DZVP-MOLOPT-SR-GTH. I think this should be a simple process, but it went wrong. <br><br>At the beginning it went well and each SCF step took 7~8s and SCF converged very fast. But after 1-2 hours it became very slow, each SCF step took several hundred seconds and the 3000s. And finally it went down. I tried it several times until I noticed that the memory occupied by cp2k was increasing linearly, i.e. it never released the memory. <br><br>I tried cp2k9.1 and cp2k8.3, all went wrong.I’m really confused and don’t know what to do.<br><br>I am really appreaciate it if you can help me with this problem.<br></div><div><br></div><div><br></div><div>Best,</div><div><br></div><div>Jessie</div>
<p></p>
