Hi all,<div><br /></div><div>I've tested the calculation on the three different compilations on my HPC cluster (7.1-Intel-2020a, 2022.1-foss-2022a and 2023.2-foss-2022a) and all three compilations crash with FFTW_PLAN_TYPE PATIENT enabled. However, the Intel version does seem to throw out some different error messages. I have attached the input and the standard outputs of the three calculations. </div><div><br /></div><div>I'm planning on doing long ab intio MD calculations and as the reference manual states "PATIENT planning is recommended for long ab initio MD runs.", so I wish to exploit this feature if possible. Can someone look into this matter or provide an answer as to why this is happening?</div><div><br /></div><div>Thanks in advance!</div><div><br /></div><div>Kind regards,</div><div>Léon<br /><br /></div><div class="gmail_quote"><div dir="auto" class="gmail_attr">On Wednesday 3 January 2024 at 16:41:13 UTC+1 Léon Luntadila Lufungula 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;">Hi everyone,<div><br></div><div>So I looked into my input file a bit further and tried switching settings on and off to find out if any of the settings is causing the crash and apparently "FFTW_PLAN_TYPE PATIENT" is the cause of CP2K crashing with CUTOFF < 800. Can someone with more knowledge of the code give their two cents if this is expected behaviour or possibly a bug in the 2023.2 version of CP2K?</div><div><br></div><div>Kind regards,</div><div>Léon<br><br></div><div class="gmail_quote"><div dir="auto" class="gmail_attr">On Wednesday 3 January 2024 at 14:50:31 UTC+1 Léon Luntadila Lufungula 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">Dear all,<div><br></div><div>A very happy 2024 to all of you!</div><div><br></div><div>I amtrying to run an ab-intio NVE trajectory to check the energy conservation for a given setup of parameters (EPS_SCF, EPS_DEFAULT, CUTOFF, REL_CUTOFF, TIMESTEP EXTRAPOLATION_ORDER) to find a suitable balance between accuracy and speed. However, when trying to reduce the value for the cutoff below 800, the calculation crashes before starting the MD run with a lot of errors written to the standard output (see attached file cutoff-700.stdout). Does anyone know why this happens and if it is a compilation problem or if it is connected to my input in some way?
