Thank you for the suggestions. When I run in PRINT_LEVEL medium the calculation stops at the same point. I have also tried running the calculation without the restart file. I will definitely try your suggestions regarding those few input parameters. Thanks for pointing out my mistake on the MAX_SCF line. We were originally using a similar input file for a much larger geometry optimization (706 atoms), so that's why I had the poor energy convergence threshold. When testing the system I just used a much smaller version of the system we were testing earlier, and I changed a minimal number of parameters, so the parameters used probably aren't ideal for this smaller system. <div><br></div><div>Hayden</div><div class="gmail_quote"><div dir="auto" class="gmail_attr">On Tuesday, February 9, 2021 at 9:01:13 AM UTC-5 tkuehne wrote:<br/></div><blockquote class="gmail_quote" style="margin: 0 0 0 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"><div style="word-wrap:break-word;line-break:after-white-space">Dear Hayden, <div><br></div><div>just a wild guess, but what WF RESTART are you reading? Was it created using exactly the same basis </div><div>and not a smaller one, in which case you may end up in a stall since CP2K tries to read more entries </div><div>from the RESTART file than is present. So you may try to simply delete the RESTART file if present. </div><div>But a few more general comments: There is no point in setting EPS_DEFAULT to 10^-14 when only </div><div>converging the „SCF“ to 10^-5. Using OT, where the mean preconditioned gradient deviation is used as </div><div>the convergence criterion, 10^-5 is on the very loose side in particular when doing total energy or even </div><div>geometry optimization. Moreover, using MAX_SCF 2500 the OUTER_LOOP is essentially ineffective, </div><div>except you were prepared to do many thousands of OT cycles ;)</div><div><br></div><div>Cheers, </div><div>Thomas</div><div><div><br><blockquote type="cite"></blockquote></div></div></div><div style="word-wrap:break-word;line-break:after-white-space"><div><div><blockquote type="cite"><div>Am 09.02.2021 um 14:51 schrieb Hayden Brandt <<a href data-email-masked rel="nofollow">br...@clarkson.edu</a>>:</div><br></blockquote></div></div></div><div style="word-wrap:break-word;line-break:after-white-space"><div><div><blockquote type="cite"><div><span style="font-family:Helvetica;font-size:12px;font-style:normal;font-variant-caps:normal;font-weight:normal;letter-spacing:normal;text-align:start;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px;text-decoration:none;float:none;display:inline!important">The input for the calculation is included below. Unfortunately I don't think I can post the full output because the file is too large. I doubt that this problem is a result of the system size, as the calculation involves just 88 atoms. I am running it on 256 cores, and the same calculation has finished in 63 minutes on a different cluster with the same number of cores. Thank you for your help.</span><br style="font-family:Helvetica;font-size:12px;font-style:normal;font-variant-caps:normal;font-weight:normal;letter-spacing:normal;text-align:start;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px;text-decoration:none"><br style="font-family:Helvetica;font-size:12px;font-style:normal;font-variant-caps:normal;font-weight:normal;letter-spacing:normal;text-align:start;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px;text-decoration:none"><div class="gmail_quote" style="font-family:Helvetica;font-size:12px;font-style:normal;font-variant-caps:normal;font-weight:normal;letter-spacing:normal;text-align:start;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px;text-decoration:none"><div dir="auto" class="gmail_attr">On Tuesday, February 9, 2021 at 8:42:19 AM UTC-5 rybk...@<a href="http://gmail.com/" target="_blank" rel="nofollow" data-saferedirecturl="https://www.google.com/url?hl=en&q=http://gmail.com/&source=gmail&ust=1612965858681000&usg=AFQjCNEvk2bGoODc8JLY9FfOKxiYz-cQQQ">gmail.com</a><span> </span>wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;border-left-color:rgb(204,204,204);padding-left:1ex">Dear user,<div><br></div><div>it may well be, that your calculation is too slow. Perhaps, it's a very large system on the small computer. In any case, it's difficult to judge without a relevant input.</div><div><br></div><div>Yours,</div><div><br></div><div>Vladimir<br><br></div><div class="gmail_quote"><div dir="auto" class="gmail_attr">вторник, 9 февраля 2021 г. в 13:38:21 UTC+1,<span> </span><a rel="nofollow">br...@clarkson.edu</a>:<span> </span><br></div></div><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;border-left-color:rgb(204,204,204);padding-left:1ex">We are running CP2K 7.1
