Hi Chris,
if memory serves correctly then the so called POSIX priority is one
range applied to all jobs. So you would be penalizing your jobs.
If you need this more often then you could either ensure that jobs
always are submitted with a negative priority (say -100) and then
regular users have a choice to go a bit above or below.
Or you use the functional policy which was more designed for what you
want to do, I think.
I also thought there might be a config parameter with which you can
influence behavior but a quick peek didn't prompt anything. So I either
was confusing this with something else or it is related to the
functional policy (didn't dig into that).
Hope this helps at least a bit (and I have not overlooked something
obvious thus confusing you),
Fritz

GE and UGE man pages are not clear about the scope of "-p" priority
values when a user uses it. It's been a long time since I needed this
and I wanted to confirm the scope of the behavior ..
Use case:
- I need to submit 100 personal jobs as "dag" with 10 jobs being
slightly more important than others
- I'm not an admin so I can't use priority values higher than 0
What I'd like to do:
- Submit 90 jobs with "-p -100" since I can't use value higher than zero
- Submit 10 jobs with "-p -10" to give priority to my 10 special tasks
My question:
- Does my use of "-p" to send lower-than-zero values for my submitted
jobs affect just MY jobs and the order in which they get dispatched or
will I end up penalizing myself globally because all the other jobs
from other users on the cluster are running with default "-p" values
of 0 assigned to them?
