Re: [HTCondor-users] prioritizing one group of machines over another

[Wayne Betts <wbetts@xxxxxxx>]

I do something similar in a small cluster with two groups of machines, in 
which I use the hostnames to determine rank.  If the hostnames are easily 
divided based on a regular expression match, you can try something like this:

NEGOTIATOR_POST_JOB_RANK = -1 * 
(regexp("<regex_for_less_desirable_hosts>",Machine)?1:0)

in which you have to supply a regular expression that will match the 
hostname of the slower, less reliable machines.

(or match the faster machines instead and change '-1' to '1').

That line is in /etc/condor/condor_config.local on the machine running the 
negotiator daemon.
