[slurm-users] Reproducible irreproducible problem (timeout?)

[Laurence Marks]

It is a University "supercomputer", not a national facility. 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.
