TaskProlog is called as a subshell? In that case it can't alter caller's
env... But IIUC someone made it work, and that confuses me...
Seems I finally managed to understand TaskProlog script! It's more
involved than I thought. :(
The script is run (on the first allocated node, IIUC) in a subshell (so
a direct export can't work), and *its output* is processed in the job
shell. Please correct me if I'm wrong.
That's why the FAQ https://slurm.schedmd.com/faq.html uses lines like
echo "print ..."
Changing my TaskProlog.sh from
export TMPDIR=...
to
echo "export TMPDIR=..."
fixed it. Now I'm quite happier :)
