Dear cp2k developers and users,<div><br /></div><div>I have two questions about the Wannier calculation in cp2k. </div><div>1. <b>Parallel efficiency of the algorithm.</b> </div><div>I found that the efficiency of Wannier calculation is almost independent of the core number used for calculation. I wonder if this calculation is implemented in parallel and what is the expected parallel efficiency. The relevant section (using Jacobi algorithm for robustness):</div><div>&LOCALIZE<br />METHOD JACOBI<br />&PRINT<br />&WANNIER_CENTERS<br />FILENAME =wannier.xyz<br />&END WANNIER_CENTERS<br />&END PRINT<br />&END LOCALIZE<br /></div><div>2. <b>Localization based on wfn or other output of cp2k SCF calculation.</b> </div><div>If the parallel efficiency of the localisation algorithm is expected to be low, I prefer to use fewer cores to perform the localisation after SCF calculation. In other words, I would like to perform localisation only for a SCF-converged calculation. Is there any way to achieve this?</div><div><br /></div><div>Thanks in advance,</div><div>Jiaxin</div>
<p></p>
