Re: [HTCondor-users] Why all jobs are sent to slots in the same machine?

[Nathan Panike <nwp@xxxxxxxxxxx>]

You could set 

requirements = SlotID == 1

But then you will miss open slots where SlotID > 1 (so it won't match slot2@xxxxxxxxxxxxxx)

Setting NUM_CPUS = 1 in the config will give you one slot per host.
