Aim-oriented Feedback-driven Auto-tuning
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Automatic feedback-driven quota tuning. Instead of setting the absolute quota
value, users can repeatedly provide numbers representing how much of their goal
for the scheme is achieved as feedback. DAMOS then automatically tunes the
aggressiveness (the quota) of the corresponding scheme. For example, if DAMOS
is under achieving the goal, DAMOS automatically increases the quota. If DAMOS
is over achieving the goal, it decreases the quota.
