Re: [Condor-users] Wildcards/regexp in Rank expression

[Steven Timm <timm@xxxxxxxx>]

In the absence of wildcards in the meantime, I just added another
attribute to the job classad, such that all jobs from group_numi
now have another attribute called

agroup

So my Rank expression now reads

Rank = ((agroup == "group_numi") * 1000)

Is that all that is needed to achieve the desired effect:
Namely,
This node will prefer to run jobs from group_numi provided
that there are jobs from group_numi available to run

I have tried to test it but my cluster is pretty big and thus far
I haven't been able to fill up the cluster enough to see whether if the
setting is making any difference.
