I was worried that I had lost the simulation, but upon booting the machine up, I heard the processor kick in.  It sounded like the simulation had resumed.

write your results, let's say every hour or 30' on your disk.
something like
if (substr(date(),...)=='30') write.table(...)
where it could take place
