[gridengine users] Signal sent to processes on requeue

[Hugh Macdonald]

Thanks Ben and Reuti,

I think (and I was reading up more on this after sending my initial 
email) that using prologs and epilogs will actually do exactly what I'm 
after - it's not so much specific job cleanup, as sending messages for 
job start/finish, which needs to happen on absolutely everything.


One question I did have about prolog/epilog scripts was how they deal 
with exit codes... The prolog script would, on the whole, exit with a 
code of 0, but how about the epilog? If the main job script exits with, 
say, 99, will the epilog run, and should that also return 99, or will 
Grid see the job script's 99 exit code, and still reschedule, even 
though the epilog script returns 0?
