Further to a discussion at the booth at PEARC23
You can limit the number of jobs that a user can submit by creating a qos that has limts set to whatever value. However the feed back to the user is not friendly (see below). A better solution would perhaps to have a data parameter, perhaps definable per partition, that would allow the OOD interface to give meaningful feedback before a user launches a job. Possibly just disabling the launch button with a tooltip feedback explaining why?
