Is this Northwestern’s Quest HPC or another one? I know at least a few of the people involved with Quest, and I wouldn’t have thought they’d be in dire need of coaching.
And to follow on with Davide’s point, this really sounds like a case for submitting multiple jobs with dependencies between them, as per [1, 2, 3].

Hence they are not that expert, which is why I am asking here. I am pretty certain that it is some form of communication issue, but beyond that it is not clear. If I get suggestions such as "why don't they look for ABC in XYZ" then I may persuade them to look at specifics. They will need the coaching, alas.
