Right. It looks like the pbs provider uses nodes= and doesn't mess with
ppn=, which means it allocate nodes as defined by the local policy
(which may mean cores instead of nodes).

I suggest setting workersPerNode to 1, but then you run into the
previous problem, which I'm trying to fix now and for which I have an
open ticket with PADS support.
