although it's not something we have working, this is something I'd be keen to have. User exclusivity on a node is something that is important to the way that we use our clusters, so we currently use 'linear'. Most of our jobs are parallel, so allocating a whole node isn't terrible wasteful, but it would be nice to use con_res, then let users choose if they want to share jobs, but only with themselves.
