(1) is the memory percentage in top for a process is relative to memory or relative to memory+swap?
(2) if it is the former, how can I get the latter? Vice versa.
(3) To determine if it is proper to run another executable, should I look into memory only or memory+swap? Or in which cases for example shall I consider which?
(4) Roughly speaking, to what extent the memory (or memory+swap) is used that I should better wait instead of submitting another job (of course it is not very small)?
Thanks and regards!
