Re: [Condor-users] How to switch jobs from idle to run state ?

[Matthew Farrellee <matt@xxxxxxxxxx>]

That's one benefit of Condor even on a single machine. Todd typically has a few slides during Condor Week about how Condor on a single machine still has benefits. You could check out the presentations...

http://www.cs.wisc.edu/condor/CondorWeek2009/monday_condor.html

As for your specific problem. If you are using the default policies in Condor and working at the machine's console then your activity there might be kicking the job off.

If you want to learn all there is to know about Condor policy you can read...

http://www.cs.wisc.edu/condor/manual/v7.3/3_5Policy_Configuration.html

Chances are all you really need to do right now is put the following in your local config file.

 START = True
 SUSPEND = False
 PREEMPT = False
 KILL = False

You can find the local config file with: condor_config_val LOCAL_CONFIG_FILE

Best,


matt
