Hi Sabuj, I think the load is only taken into account if you leave NODEAVAILABILITYPOLICY with the default setting or explicitly set UTILIZED or COMBINED (for PROCS). I prefer to set NODEAVAILABILITYPOLICY DEDICATED So that processors are logically allocated rather than considering load. -- Gareth _______________________________________________ mauiusers mailing list [email protected] http://www.supercluster.org/mailman/listinfo/mauiusers
