[Pw_forum] Estimation of cpu time required without actually doing the calculation

[Prasenjit Ghosh]

Dear all,

Is there some way to estimate the time required for doing an scf iteration
using pw.x, without actually performing the calculation ?

I tried to make an estimate following the guideline given in the manual and
compared it with the actual CPU time required......the two results are not
matching......I am getting an abnormally high estimate of the CPU time
required........most probably I am doing something wrong.

By the way, in what units will I get the time by using the procedure
mentioned in the manual?

With regards,

Prasenjit
