Dear CP2K community,<div><br /></div><div>I am running PBE0-D3 (50% HFX exchange) on several molten salt systems and I found that LiCl system is running much slower than KCl (I used identical input files for them, except coordinate-related information).</div><div>The following is HFX information the log file reports:</div><div>For LiCl:</div><div>
