Re: [Condor-users] condor_rooster - how does it work


condor_rooster depends on there being offline ads for the hibernating machines. The offline ads are created when HIBERNATE becomes true, assuming your collector has been configured to support offline ads (configure OFFLINE_LOG).

Does that help?

Hello All,

As someone who has spent a lot of effort in tying to get our Condor pool to
work with power saving Windows execute hosts I was very interested in
using condor_rooster to wake up machines automatically according to
demand but I cannot for the life of me understand how it works.

Currently the power saving is performed by 3rd party s/w and we do
not use the hibernating features built into Condor. As far as I can
tell when the power saving kicks in, the Condor daemons get killed
and the machine disappears from the pool. I can't work out how
condor_rooster can work out if these machines are available for
wakeup when they are no longer publishing ClassAds.  I don't
see any persistent ClassAds for them - do I need to use the
HIBERNATE in the execute host config ?
Is there any more documenation available on this - the v. 7.4 manual is a bit
short on info on this.

thanks - in - advance,
