My most critical Maui bug is logged in your bugzilla as number 141.
(There are also a bug number 83, that looks similar.)
Please include it within "all known bugs", that you are fixing now! I would
really appreciate that.
The MAXNODE configuration parameter does not work.
It should be easy for you to repeat the problem on your systems:
1/ Start with a simple Maui configuration like (I skip the
SERVER*/ADMIN/RMCFG/RMPOLLINTERVAL/LOG* preambles):
QUEUETIMEWEIGHT 10
XFACTORWEIGHT 1
QOSWEIGHT 1
FSPOLICY [NONE]
BACKFILLPOLICY BESTFIT
NODEALLOCATIONPOLICY LASTAVAILABLE
RESERVATIONPOLICY CURRENTHIGHEST
RESERVATIONDEPTH 10
JOBPRIOACCRUALPOLICY FULLPOLICY
NODEACCESSPOLICY SINGLEJOB
JOBNODEMATCHPOLICY EXACTNODE
QOSCFG[DEFAULT] PRIORITY=10000 XFWEIGHT=1000 QTWEIGHT=4
2/ Add MAXNODE lines for a user and the group of that user, like:
USERCFG[lka] MAXNODE=5
GROUPCFG[nsc] MAXNODE=5
3/ Submit a lot of jobs as that user and wait until her/his jobs run on
a total of at least five nodes.
4/ Run a 'showq' and look at all the jobs of that user, that should be
'blocked', but actually is 'idle' (the demonstration is done on a system
where each node has only one processor, and here MAXNODE could be
substituted with a MAXPROC, but most of our systems have more than one
processor on each node):
# showq

6 Idle Jobs
BLOCKED JOBS----------------
JOBNAME USERNAME STATE PROC WCLIMIT QUEUETIME
5/ Only job number 55818 should be running, the other 'lka' jobs should
be 'blocked' and neither 'running' nor 'idle'.
The demo was run with Maui version 3.2.6p19-snap.1171482917.
I would at least like the MAXNODE parameter to work for GROUP, QOS or
CLASS, but of course it would be nice to have it working also on USER,
please.
