<div dir="ltr">Hi,<div><br></div><div>Thanks for pointing out the time estimate for me. The largest ADMM basis I can afford is FIT11 for Cs, Ag, In and pFIT3 for Cl. Also with these larger basis, the band gap change is quite small, say 0.015 eV. With larger ADMM basis, the band gap tends to be slightly smaller, contrary to the case of Si. Is the behavior of nonsensitive dependence on the ADMM basis related to the high ionicity of the present structure?</div><div><br></div><div>Best,</div><div><br></div><div>Xiaoming<br><br>On Tuesday, September 19, 2017 at 11:05:39 AM UTC-4, jgh wrote:<blockquote class="gmail_quote" style="margin: 0;margin-left: 0.8ex;border-left: 1px #ccc solid;padding-left: 1ex;">Hi <br> <br>I would first try a larger ADMM basis, e.g. pFIT3. <br> <br>The increase in CPU time for a full exchange calculation with <br>MOLOPT basis sets can be 100x - 1000x. <br> <br>regards <br> <br>Juerg <br>------------------------------<wbr>------------------------------<wbr>-- <br>Juerg Hutter Phone : ++41 44 635 4491 <br>Institut für Chemie C FAX : ++41 44 635 6838 <br>Universität Zürich E-mail: <a href="javascript:" target="_blank" gdf-obfuscated-mailto="NhuL_fvBAgAJ" rel="nofollow" onmousedown="this.href='javascript:';return true;" onclick="this.href='javascript:';return true;">hut...@chem.uzh.ch</a> <br>Winterthurerstrasse 190 <br>CH-8057 Zürich, Switzerland <br>------------------------------<wbr>------------------------------<wbr>--- <br> <br>-----<a href="javascript:" target="_blank" gdf-obfuscated-mailto="NhuL_fvBAgAJ" rel="nofollow" onmousedown="this.href='javascript:';return true;" onclick="this.href='javascript:';return true;">cp...@googlegroups.com</a> wrote: -----To: cp2k <<a href="javascript:" target="_blank" gdf-obfuscated-mailto="NhuL_fvBAgAJ" rel="nofollow" onmousedown="this.href='javascript:';return true;" onclick="this.href='javascript:';return true;">cp...@googlegroups.com</a>> <br>From: Xiaoming Wang <br>Sent by: <a href="javascript:" target="_blank" gdf-obfuscated-mailto="NhuL_fvBAgAJ" rel="nofollow" onmousedown="this.href='javascript:';return true;" onclick="this.href='javascript:';return true;">cp...@googlegroups.com</a> <br>Date: 09/19/2017 04:46PM <br>Subject: [CP2K:9441] Re: Hybrid functional calculation results show large difference with VASP <br> <br>Hi Marcella, <br>What do you mean by the 'smaller version'? If you are meaning a smaller basis set for ABS, I did the test. To my surprise, the results don't change much when I go to the smallest ABS, say cFIT3 for Cl, cFIT9 for Ag and In, cFIT7 for Cs. Is this behavior reasonable? <br>Without ADMM, it seems that the computation would take extremely long time with the same cpu cores. With ADMM, I can finish the calculation within couple of minutes. However, without ADMM, it has taken me almost one hour and the first OT step hasn't even appear in the output. Does this sounds reasonable as well? <br>Best,Xiaoming <br> <br>On Tuesday, September 19, 2017 at 4:58:43 AM UTC-4, Marcella Iannuzzi wrote:Hi, <br>Can you test your system without ADMM?

To be specific, I compared the DZVP and TZVP basis sets. The difference of the PBE band gap is within 0.01 eV. The PBE0 band gap without coulomb trunction also shows small difference, say ~0.01 eV. The band gap variation by coulomb truncation as in PBE0-TC-LRC scheme is larger, say 0.05 eV, but still not too much. <br>Any other advice? <br>Best,Xiaoming <br> <br> <br> <br> <br> <br> <br>-- <br> <br>You received this message because you are subscribed to the Google Groups "cp2k" group. <br> <br>To unsubscribe from this group and stop receiving emails from it, send an email to <a href="javascript:" target="_blank" gdf-obfuscated-mailto="NhuL_fvBAgAJ" rel="nofollow" onmousedown="this.href='javascript:';return true;" onclick="this.href='javascript:';return true;">cp2k+uns...@googlegroups.<wbr>com</a>. <br> <br>To post to this group, send email to <a href="javascript:" target="_blank" gdf-obfuscated-mailto="NhuL_fvBAgAJ" rel="nofollow" onmousedown="this.href='javascript:';return true;" onclick="this.href='javascript:';return true;">cp...@googlegroups.com</a>. <br> <br>Visit this group at <a href="https://groups.google.com/group/cp2k" target="_blank" rel="nofollow" onmousedown="this.href='https://groups.google.com/group/cp2k';return true;" onclick="this.href='https://groups.google.com/group/cp2k';return true;">https://groups.google.com/<wbr>group/cp2k</a>. <br> <br>For more options, visit <a href="https://groups.google.com/d/optout" target="_blank" rel="nofollow" onmousedown="this.href='https://groups.google.com/d/optout';return true;" onclick="this.href='https://groups.google.com/d/optout';return true;">https://groups.google.com/d/<wbr>optout</a>. <br> <br> <br></blockquote></div></div>
