[OOD-users] Jupyter App -- satisfy password request && database connection error

[Shawn Doughty]

Hi,

You mean jupyter notebook? I used the regular batchconnect version from OOD
git and then just tweaked a couple of settings using native slurm
connection. This shouldn't have to go over TurboVNC?   Happy to send you a
copy of our setup here.  Users are really liking jupyter, the only thing I
noticed is it has a tendency to barf when running out of memory which is
why we give users the choice to pick cores and memory.
