Subject: [PATCH] Scheduler-test: implement base offset per node
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

...actually difficult to integrate into the existing scheme,
which is entirely level-based. Can only be added to the individual Jobs,
not to the planning and completion-jobs — which actually shouldn't be a problem,
since it is beneficial to dispatch the planning runs earlier
