As long as Grid Engine is not using more job slots than the configured number
(the no. of processors in the system by default), then it is the correct
behaviour.
The OS should spread the tasks around evenly.How many tasks are there on your
12-core machine?

Well. But how can I avoid that processor cores are allocated twice? If I use
"-binding" to qsub than I first must know which cores are already used on the
whole cluster and then choose the ones which are free. Is there not a less
circuitous way?
