[gridengine users] "Packing" jobs on nodes

Our clusters are homogeneous, so we are trying to do a first-level sort
on "load" where the load formula is simply "slots". If it did this much
correctly I could happily ignore it's second-level behavior. Have you
ever made this work as a first-level sort?
We have two clusters, one running 6.1u5 and the other running 6.2u2-1.
The 6.2u2-1 system appears to sort by sequence number in defiance of my
instructions to use "load" with a load formula of "slots". I have not
actually been able to deduce a coherent pattern of behavior for the
6.1u5 system, but it is clearly not packing the jobs.
What is the "Univa repo" you refer to?
