Sorry, I'm just getting back around to this. I am trying to convert things
now. Most of it is straightforward, but I am further confused about time
limits. (Maybe that is the seed of my original problems.) Consider this
SRDAYS[userver171] MON TUE WED THU FRI
If I understand correctly from reading the TIMELIMIT description the
SRMAXTIME would have allowed anybody to use up to 5 hours of time during
Kim's standing reservation. Is that right? My original flawed intent was
to allow jobs outside the standing reservation period to use up to 5 hours
of CPU time.
So, I want Kim to have full access from 7am to 4pm and for nobody else's
jobs to be started during that time (it's ok if a job is started before but
complete during the reservation period). Further, outside the reservation
period I want to allow jobs to consume a maximum of 5 hours of CPU time.
How do I spell that? My first guess would be to define three reservations
to cover the entire 24 hours per day, 7 days per week. Something like this:
# Weekdays - Kim gets exclusive use
SRCFG[userver171] STARTTIME=07:00:00 ENDTIME=16:00:00
# Off hours weekdays - as above, except
SRCFG[userver171] STARTTIME=16:00:00 ENDTIME=07:00:00
# Weekends - as above, except
SRCFG[userver171] STARTTIME=00:00:00 ENDTIME=23:59:59
What I'm really after is a single queue (simpler user interface) with some
nodes having different properties at different times of the day or week
(established via config). Users should be able to submit jobs at any time
and "admin" (that would be me) shouldn't have to tweak node properties
on-the-fly to satisfy demands of the interactive use of the nodes.
Is there a tutorial on Maui configuration somewhere? I can't seem to find a
discussion of how this stuff works in the user or admin guides, though it
must be buried in there somewhere.
