60 atoms/cell is a very large primitive cell/supercell. I once tried with 58
atoms /cell with 1200 k-points and RMT=8.00. 1 SCF cycle took almost over 3
hours on 72 processors. So I reduced my k-mesh and ran the SCF
(non-availability of processors !!!!). 
If you do the same, may be on 100 processors, then you can expect 1 SCF
cycle to take around 1-2 hours.

Dear all,
 
I am new to this Wien2k program. So would you please answer me? Will it take
only hours or 1-2 days to run? 
 
I know the question might be too trivial, but hopefully those who have
experiences can help me out.
 
Thanks,
chee
