[Pw_forum] optimizing pw input parameters

[meisam aghtar]

Dear all
which parameters should be optimized sequencly in a scf runing? the parameters are celldm(1),ecutwfc, ecutrho,mixing-beta and K-points.
another problem is that for optimizing the ecutwfc the system converges for some numbers and it doesn't for some more. I have to mention that there is overlap in davidson diagonalization.
