[Condor-users] Antwort: Re: can jobs be executed while the condor submitter isturned off ?

[Tao.3.Chen@xxxxxxxxxxxxxxxxxxxxxxxxxxx]

Hi, Alex,
       Thank you
so much!
        I also checked
the condor workshop presentation, in it the job startup steps are  as
follows:
1. Startd sends collector ClassAd
describing itself.  (The Schedd does as well, but it has nothing interesting
to say yet.)
2. The user calls condor_submit
to submit a job.  The job is handed off to the schedd and condor_submit
returns.
3. The schedd alerts the collector
that it now has a job waiting.
4. The negotiator asks the collector
for a list machines able to run jobs and schedd queues with waiting jobs.
5. The negotiator contacts the
schedd to learn about the waiting job.
6. The negotiator matches the waiting
job with the waiting machine.
7. The negotiator alerts the schedd
and the startd that there is a match.
8. The schedd contacts the startd
to claim the match.
9. The schedd starts a shadow to
monitor the job.
10. The startd starts a starter
to start the job.
11. The starter and the shadow
contact each other.
11. The starter starts the job.
12. If the job is using the Condor
syscall library (typically through being condor_compiled), it will contact
the shadow to access necessary files.
      hmm....... So I
think you are right, the whole condor system architecture is designed as
the above, it is impossible to change. But I am not sure if there is any
special design which is adapted to the submitter off?Also, for my work
now ,I  need this kind of system which would allow the submitter unplug
or shutdown, and the jobs work well, any ideas?
 Good Luck!

No, In my experience the
submitter needs to be online until the last jobs’ execution is completed.
That is using the default configuration after installing condor in the
execute node. Every time I tried either to shutdown or unplug the computer
after submitting a set of jobs, the jobs go immediately into the hold state.
The reason why I leave it to some more experienced condor user.
I hope this statement
at helps a little in your quest of answers,
Respectfully,
Alex.

Hi, 
         I have read the manual and the some presentations
carefully, found that during the execution of job, the schedd daemon should
watch the progress of executing machine. And for the jobs in the queue,
the schedd daemon will maintain the persistent queue, contact the available
machines and match the job with executing machines. 
        does that mean if I submit several jobs in
the queue, the submitter should keep online and contact with the central
manager and the executing machine?
        Is that possible after submitting the jobs,
the submitter could be shut down, and the central manager takes the response
for the whole jobs?  Or are there any other kinds of software could
achieve this target? 
 Any ideas would be appreciated! Thanks in advance!
