Re: [Condor-users] Backup Scheduler

[Alex Iosup - EWI <A.Iosup@xxxxxxxxxx>]

Hermann,


You could try the High Availability Daemons [ http://research.cs.wisc.edu/condor/manual/v7.0/3_10High_Availability.html ]. Section 3.10.1, High Availability of the Job Queue, is what you're looking for. Afair, Condor is using a hot spares and a fail-over mechanism.

Regards,
Alexandru
