Dear Li
I think using -nk is more straight forward, unless you only use very few k points.
Best wishes.

主题: [Pw_forum] diago_david_ndim


Dear QE users,
         In the manual, I found increasing the diago_david_ndim can lead to a faster calculation. Can I obtain a very high speed-up by endlessly increasing the value of diago_david_ndim  as long as the memory of my machine is enough?




Best regards!
