Hi, first, thank you for this awesome software!<br /><br />I am planning to run a lot of water single point calculations (forces and energies) for water on LUMI-G. I am currently using this installation https://lumi-supercomputer.github.io/LUMI-EasyBuild-docs/c/CP2K/#user-documentation. This recommends a slightly different setup (6 openMP vs 3 in https://pubs.aip.org/aip/jcp/article/158/16/164109/2886896, which I understand was done during pilot phase). Is this installation up to date, and what is generally the best jobsetup currently?<div><br /></div><div>Then, to get best performance for hybrids and double hybrids on LUMI, do you have any specific recommendations? From https://pubs.aip.org/aip/jcp/article/160/6/064116/3263749, https://pubs.aip.org/aip/jcp/article/160/6/064116/3263749, https://pubs.aip.org/aip/jcp/article/158/16/164109/2886896, and rapid developments I am little confused on what I should be running to get reasonable numerical accuracy (at each level of theory) for lowest amount of cost. So far it seems standard input file (4c) for hybrid functionals and use the SOS of https://pubs.aip.org/aip/jcp/article/158/16/164109/2886896 for RI-MP2.</div><div><br /></div><div><br /></div><div>All the best,</div><div>Sigbjørn</div><div> </div>
