Re: [Condor-users] job submitting to powerful machines.

["Alas, Alex [FEDI]" <aalas@xxxxxxxxxxxxx>]

Ian,
Thanks for your help, I think I need to give you more details of my
condor farm. I have 4 windows 2003 machines with 4 cpu per each box to
make a total of 16 CPU's for windows 52 boxes, and 3 windows xp machines
with 2 CPU's per each box to make a total of 6 CPU for windows 51 boxes.
The grand total of my pool is 22 CPUs. Below is a shot of my pool after
running condor_status.
I tried to apply your suggestions and I come up with the requirement
expression (REQUIREMENTS = (OpSys == "WINNT52" && SlotID == 3 || SlotID
== 4))  and it will run jobs on all windows 2003 machines on processors
3 and 4, if I use slotId 1 and 2 it will run it on xp and 2003 boxes on
slotid1 and slotid2. How can I direct my jobs for example to machine6 to
slots 1 and 3, Only. Or to all CPU's on machine6. 
Thanks for your help in advance,

Use rank if you want your jobs to *prefer* the better machines, but
don't care if it runs on the lesser machines. Use requirements if you
*only* want your jobs to run the better machines. The simplistic view of
Rank and Requirements:

        Requirements define what machines show up on the list of
possible matches.
        Rank helps sort the list.
        Top of the list gets popped and tried first.

If you always want to run in slot 1 or 2 regardless of how many CPUs the
machine is advertising:

requirements = SlotID == 1 || SlotID == 2

If you only want to run in slot 1 or 2 on machines that have >2 slots
advertised:

requirements = (TotalSlots > 2 && (SlotID == 1 || SlotID == 2)) ||
(TotalSlots <= 2)

No problem? :)
