Exercise 5. Modify the task scheduling algorithm of Section 9.1.7 to allow the
controller to serve more than one task per frame. Specifically, every frame k the
controller chooses a service action s[k] from a set S of possible actions. Each
service action s ∈Sdetermines a clearance vector c(s)=(c
1
(s),...,c
N
(s)),
where c
i
(s) is the number of tasks of type i served if action s is used on a
given frame. It also incurs a delay
ˆ
D(s) and energy ˆe(s).
