With blocked, do you mean that they are in Idle state or Deferred state?
I assume your jobs are Idle, that is, do the largest jobs stay on the top of
the list when you do showq -i. (If not, you have set some throttling policies
in maui that prevent them from becoming eligible for scheduling.)
Have you set the RESERVATIONDEPTH in maui.cfg?
We have set
to make the three jobs with highest priority set reservations on nodes so they
can build up resources over time until they are able to start. Backfill makes
it possible to fill in shorter jobs while the big jobs are waiting to start.
