Hi Abhi, We don't quite do what you want but this setup may be OK for you. Create a standing reservation on the nodes that allows either jobs from group 'X' _or_ jobs under a particular walltime limit. That way the nodes can free up for group X within the given walltime. Tune that walltime limit to be acceptable to your community. Adding priority is a bit trickier. You might not want group 'X' to have a global higher priority (though that would be an option). You could add a queue 'Y' with an acl such that it is only accessible by group 'X' and have a priority on the queue (that is the class in maui). If you want to make the class only use the reserved nodes you would need additional settings. -- Gareth _______________________________________________ mauiusers mailing list [email protected] http://www.supercluster.org/mailman/listinfo/mauiusers
