How to stop Mavericks from sleeping when display turns off?
I use my iMac to run processes that go overnight. But, the Energy Saver panel in OS X Mavericks no longer shows separate controls for "display sleep" vs "computer sleep".
I want the display to sleep after a short time, but want to set the computer to not sleep at all when I have a process for it to run that will take many hours.
How can I set this?
Right now, it looks like I have to have the display set to never sleep all night, in order to have the computer never sleep, which is pretty bad!
Thanks very much for any help,

(To be clear, with the default settings the computer definitely did go to sleep even though my program was still running -- a process that should have taken about 3 hours instead sat all night and finished only when I woke the computer in the morning, making me wait the final two hours for it to finish. This is R code that calls ImageJ routines repeatedly.)
