At the moment I don't know if I checked it with "qstat -j", but I checked it - 
when I'm in the office again I probably have the output still on some screen 
window so I can tell it exactly. And I did do a test: I removed the PE 
temporarely from the queue - with the result that the jobs could not start 
anymore (as respected).
