I tried with nodes=9 now. A bit better than ncpus=9, but unfortunately 
still wrong:

Messages:  cannot start job - RM failure, rc: 15044, msg: 'Resource 
temporarily unavailable REJHOST=node37 MSG=cannot allocate node 'node37' 
to job - node not currently available (nps needed/free: 4/1,  joblist: 
PE:  9.00  StartPriority:  -89
job can run in partition DEFAULT (47 procs available.  9 procs required)

For some unfathomable reason it is trying to allocate 4 procs on node37... 
Even though there are other nodes with 4 processors available... Or it 
could pick 1 processor from node37 and the rest from other nodes.

Best regards,
