I made sure that no 2 schedulers are running at the same time. So 
unfortunately that is not the issue.

I am stuck with using properties in server_priv/nodes and submitting 
jobs with "-l nodes=1:property". At the moment this is an acceptable 
workaround since the property scales 1:1 to the processors. But once I 
need _1_ resource per machine and not per cpu this approach will not 
work any more.

qsub -W -x="GRES:resname" will just not work here. Does anyone have 
another idea what I might have missed?
