William, thank you for your advice.
I will try both.

Hi,
I tried to understand load scaling. But it is still unclear for me.
Let's assume two hosts.
hostA very fast machine
hostB regular speed machine
Even though np_load_avg of hostA is much higher than hostB,
a job still runs faster on hostA. But in this case gridengine usually
submits the job to hostB because its np_load_avg is lower.
I want to tune this environment by changing load scaling.
But I don't know how.
There probably isn't a built in "load sensor" that directly reflects what you
want. You could:
1)Write your own load sensor that reflects your notion of which node is more
preferable then use that for the load_formula.
2)Change the queue_sort_method to seqno and give the queues on hostA a lower
sequence number. You could add a
np_load_avg based load_threshold that will stop jobs being assigned to a host
if it is overloaded.
