Calculation Time
« on: April 6, 2017, 12:12 »
Hi. Nanosheet with 96 atoms has 48 reduced k points. Nanosheet with 72 atoms has 64 k points. Which one's dft calculation finishes early?

Given a small difference in the number of atoms as well as in the number of k-points for these two cases, it might be faster to actually do these two calculations than to guess which of the two is the fastest.
