and now the earth is rotating again in a right direction

thanks

There is an expert parameter which allows you to output wall clock time in the output, should be useful in your case.

Code:

Wall clock time = t

ok, i'll try it, thanks!

Here, the wall clock seconds means the required time for the solution only, or the partitioning etc is involved?
