Dear Dongbo Wang, 

in case you already have a converged WF using the same basis set etc., you can simply 
restart by SCF_GUESS RESTART and set MAX_SCF 1 to do a single diagonalization to 
compute your properties.

Best, 
Thomas Kühne

> Here, the non-scf computation mentioned is based on a converged result from scf computation. And I think this non-scf computation is necessary in some task, for example, computing band structure, DOS and some optical properties for large system. Programs like VASP (ICHARG keyword control it) and PWmat give option to do non-scf calculation. I am not sure CP2K have a same module to do non-scf. If some similar keywords exist, please let me know. Thank you so much.
