Right now, the user can see what node is running a given job, but there is no listing of all jobs currently being executed. There is also no way to see all jobs running on a particular node. After a request from a project operator and a good amount of discussion, it has been brought to my attention that the Resource Manager client has a good number of options for providing information about specific things but doesn't provide much in the way of broad info.
Therefore, to help in that avenue, I think that the RM needs a feature that will list all jobs executing and show what nodes are executing those jobs in addition to whatever other info is needed by the user. Currently, the additional info requested is the queue name and load value of the listed jobs.
