Hi Varun,
For each of your questions below, the answer depends on how your local
administrator configured it.
The "mf" probably just checks that amount of memory is available at job
start, but does not reserve the memory.
The request can be configured to be per slot or per job.
Similarly, "cores" can be configured to map to "slots" or to something else.
If you request more than one slot, those allocated slots can be on the
same machine or across multiple machines, depending on configuration.
'man sge_intro' is a good start, but there is also the docs collected
here: http://arc.liv.ac.uk/SGE/howto/howto.html

HI Everyone,
I have been using SGE for some time but I still have lots of doubts. I
hope to find my solution here.
When I submit my job using qsub and using arguments like -l mf=8G does
-l mf=8G provides me 8GB ram for that job to run??
This job which i Submit runs on one computer or several computers??
What does slots mean when I use qstat I see slots = 1. When I use -pe
threaded 2 as one of the arguments of qsub slots changes to 2.
Does this also mean when I use the command qsub -l mf=8G -pe threaded 2
, the total memory(RAM) becomes 16 gb (8x2) and this job is now running
on 2 computers??
Also what do we mean by cores?
Is there a manual apart from man pages where I can read about these
things for SGE
Hope to hear from you
Regards
varun
