Assume you have two queues, queue A with some new hardware, and queue B with old hardware. Further, both queues have the same number of nodes and slots for SGE jobs, e.g. 10 slots per queue.
Now I submit 10 jobs. If both queues are empty and the nodes have the same load, I guess 5 of the jobs will run in queue A and 5 of them in queue B. But since B has older hardware, the jobs will take longer to finish.
Is there a way to ask SGE to try and "fill" the fast nodes in queue A first before "backing off" to the old queue B? I'm asking about both user and admin side of the question.
