Colin has answered most of your questions but I should point out:
1) Dagman uses the scheduler universe. you could also use it yourself
as a kind of service lite since it will always run on your local
machine and auto restart if the machine / condor service itself is
2) And more importantly from bitter experience:
If a user has changed their password since the last store cred their
jobs will still be accepted by the schedd system but when attempting
to run them they will fail to start. this then means you have a job
bouncing round the farm going through the claim cycle on multiple
machines for no useful effect.
This is very annoying and not tereribly obvious to the end user since
they simply see their job running (if they are clever they may notice
the machine changes a lot or stays in the ?????????????? state a lot)
but not getting anywhere.
If you can find a way to trigger a store cred on password change I
would suggest using it since the grief you get if the job triggers
preemptions across half your farm is immense...sadly this isn't
possible for me
It would be nice if someone from Condor could someone indicate if this
is a fixable problem or not...
