[Condor-users] running commands when jobs start and stop

[Jeff Strunk <jstrunk@xxxxxxxxxxxxxxx>]

Since Condor 7.2 isn't ready to put our computers to sleep yet, we are 
using sleepd. sleepd can be prevented from making a computer sleep by 
running the command 'sleepctl off'. I wrote a wrapper in bash for that 
and set HOOK_PREPARE_JOB to run it. I did the same thing for 
HOOK_JOB_EXIT to enable sleeping.

I noticed that HOOK_PREPARE_JOB gets run when condor starts up and when 
a job is about to run. This make our computers never sleep. Is there a 
better hook or a way to make this hook only run when a job is starting?

Since this hook gets the classad as stdin, I tried adding the following 
to my wrapper to prevent it from running when no job is about to run.

if ( [ ! -t 0 ] && ( cat - | grep -i mytype | grep -i job > /dev/null ))

This should only succeed if STDIN has a line like:
MyType = "Job"

Unfortunately, my test systems say that sleeping is disabled after 
condor is restarted.

Any suggestions?
