Hi Andreas,

the prioritisation I seen on one of my clusters is something like

16308 0.08690 debug      dph0elh      r     02/18/2007 17:38:28 miranda.q at m2007   128

.....
the priorities are different and adjusted by the system.

on my new set up of another cluster is see

-----------------------------------------------------------------------------------------------------------------

   2906 0.55500 xi.0.1_470 irpn         r     02/27/2007 15:23:39 medium.q at cdm10.phyastcl.dur.ac     1 85
   2906 0.55500 xi.0.1_470 irpn         r     02/27/2007 15:23:39

All the priorities are the same.


I compared the configurations of both and I could not see any difference ..



the output of qconf -ssconf is
