[GE users] Subjob or parent/child semantics in SGE?

Grid Engine does not currently support the concept of a parent/child 
relationship between jobs. You're on the right track for building it 
yourself, though. If you use a strict naming pattern and a custom 
terminate method, you should be able to get the subjob behavior.

Having worked quite long with LSF/Symphony this was a handy feature, e.g. if the parent job had been killed all the subsequent child jobs have been killed automatically as well if necessary. This of course is only possible if the middleware knows about this relationship between the jobs.
