[gridengine users] One queue subordinate to two others

[Bastian Kronenbitter]

Hi Reuti,

Thank you for the fast answer.
Unifying them isn't really an option. They have different runtime and 
overall slot limits.
When I try to configure the queues the way you say it, I get the 
following message at the second queue:

denied: adding "B.q" to the subordinate_list of "A.q" would create a 
loop in the slotwise preemption configuration!

But first tests indicate, that configuring one the queues is sufficient. 
So thank you very much. I'll run some more tests, but right now I'm 
happy with this solution.

Regards, Bastian
