Dear CP2K experts<div><br /></div><div>I attempt to simulate hydrated electron in the gas phase using B3LYP functional. The usage of ADMM does not speed up my simulation. It is slower (~25s per step) than simulation without using ADMM (~21s per step). I have tried to lower EPS_SCHWARZ to 1.0E-6 but it is still slower at ~25s per step.</div><div><br /></div><div>I would be very grateful for any possible advice with my input, and insight into the usage of ADMM for performance improvement. I am using CP2K v2024.1 compiled with libint-lmax=7 and MAX_CONTR=4. I am new to CP2K.</div><div><br /></div><div>I have attached the input/output files for the 2 simulations.</div><div><br /></div><div>Thank you!</div><div>Jia Yang</div>
