Hi,
Thanks for the clarification. I did not realize there was a hierarchy to
the node access policy and it looks like Maui obeys the same rules as
Moab in that regard. The CLASSCFG[] setting does not work for Maui,
unfortunately, but I was able to get what I want by reversing the
problem -- i.e. setting the default NODEACCESSPOLICY to be SHARED and
then setting SINGLEJOB only for all the parallel jobs via the submit
filter (by adding the RM extension).

Jay,
I was investigating this very issue myself recently. The documentation
is pretty clear (when you find the right place) in that you can only
increase the restrictions, SHARED is the lowest level.
Read the "Note" located here:
http://www.clusterresources.com/products/mwm/docs/13.3rmextensions.shtml#naccesspolicy
One possible option, although I'm not sure it is currently available
MAUI, would be to setup different queues with different policies.
The MOAB documentation says this can be done with the following setting:
CLASSCFG[batch] NODEACCESSPOLICY=SINGLEJOB
I am running MAUI, not MOAB, but have not tested this function.

Hi,
I'm trying to use the RM extensions with Maui 3.2.6p20 and Torque
2.3.0. My default setting in Maui for node allocation parameters is
as follows:
NODEACCESSPOLICY SINGLEJOB
NODEAVAILABILITYPOLICY DEDICATED
NODEALLOCATIONPOLICY MINRESOURCE
But, I'd like to submit a job to a serial queue that allows for SHARED
node access, and so I submit a job as follows:
qsub -Wx=NACCESSPOLICY:SHARED serial.job
where I request -lnodes=1:ppn=1
But this seems to be getting ignored and Maui continues to assume the
node access policy is SINGLEJOB. The log file shows the following
(where it seems to show that it accepts the RM extension but ignores it).
11/18 12:10:36 INFO: PBS attribute 'submit_args' value:
'-Wx=NACCESSPOLICY:SHARED serial.job ' (r: NULL)
11/18 12:10:36 INFO: PBS attribute 'x' value:

11/18 12:10:36 MQOSGetAccess(1493,NULL,QAL,QDef)
My question is whether the RM extension for NACCESSPOLICY actually
work? Am I missing some other setting (in Torque, for instance) that
needs to be done for this to work? I've tried the same syntax with
other RM extensions (HOSTLIST, for example), and those work, but
NACCESSPOLICY does not.
Thanks for any help.
Jay
