Re: [Condor-users] Configuration

[Dan Bradley <dan@xxxxxxxxxxxx>]

Joe,

Support for this sort of group sharing policy is in active development.  
In lieu of the full solution, there are various ways to get almost what 
you want, with some undesired consequences.

One way is to pre-assign 100 machines to the group so that their jobs 
only run there.  Example:

#In the global condor_config
START = (...) && (TARGET.Group =?= UNDEFINED || MY.Group =?= TARGET.Group)
STARTD_EXPRS = Group
SUBMIT_EXPRS = Group

#In the local config file on the 100 machines:
Group = "OSG"

Depending on whether you also want them to have absolute (preemption) 
priority on those machines, you can also set the machine RANK expression:

RANK = TARGET.Group =?= MY.Group

The main disadvantage to this setup is that the 100 nodes are hard-wired 
rather than being chosen opportunistically.
