I have a question. I want to have cpt file every 10 000 000 steps. Is it possible to do that? I know that I can use option -cpt to save every specific time in minutes, but is it possible to do it in case of steps?
no that is not possible. An option is to stop the run at the desired number of step to get cpt file at a desired point and save it.
