Is it possible to save a running program and reload next time ?

Hi,

I have a program which will continue to run for several days. When it is 
running, I can't do anything except waiting because it takes over most 
of the CUP time.

Is it possible that the program can save all running data to a file when 
I want it to stop, and can reload the data and continue to run from 
where it stops when the computer is free ?

Regards,
