Hi Reuti,

I will answer for Jakob here as I am the guy who has set up the cluster
config.
Btw. SGE version is 8.1.8.

No. We use queuewise subordination. I did a couple of lengthy tests with
slotwise subordination but did not get any reliable results. I cannot
recall in detail what the problems were but it was so that we switched
to queuewise subordination.

Current config is

ssconf:
queue_sort_method                 load
load_formula                      np_load_avg

short.q:
subordinate_list      normal.q=1,medium.q=1

medium.q:
subordinate_list normal.q=1


Queuewise subordination works reliable in the respect that jobs are
suspended. It does not work at all when it comes to schedule depending
on queue hierachie.

My impression of the cause of the problem is that the rule for choosing
a node is still "least loaded". The queue running on a host is not taken
into account for this first decision.

So we have the situation that the suspending can happen to any queue
that happens to currently run on the least loaded node.


Regards

Gerik
