Looking at the docs (http://www.clusterresources.com/products/maui/docs/13.3rmextensions.shtml#NACCESSPOLICY
) from the page you gave..... It shows a colon between arguments
naccesspolicy and singlejob. So, naccesspolicy:singlejob should be
what your trying. Did you try that?

According to the maui docs, the node access policy can be overridden
on a job-by-job basis using the naccesspolicy (described at the link
below). I’m able to submit my job with a singlejob node access
policy, but it appears that maui is letting other jobs onto the
nodes. Does this feature of maui work?
http://www.clusterresources.com/products/maui/docs/5.3nodeaccess.shtml
I have a cluster of 8 nodes with 2 processors each. The
jobnodematchpolicy is exactnode, so I get 8 processors on different
nodes when I submitting with qsub
qsub -l nodes=8:ppn=1,naccesspolicy=singlejob $myjob
Afterwards I submit another job with
qsub -l nodes=8:ppn=1 $mynextjob
I expect the 2nd job to wait because all 8 nodes are running with a
singlejob access policy. Instead this job gets 1 processor per node
and starts running right away.
Am I misunderstanding the nodeaccess policy?
