Scheduling is a resource management framework allowing to trade precision for timeliness.
In this talk, in addition to presenting the optimal and efficient solution to the optimal periodic RBRT Scheduling problem, we describe how the framework can be used to express and exploit tradeoffs on additional requirement dimensions such as power-efficiency and reliability without compromising timeliness. In RBRT scheduling model, each real-time task is logically decomposed into a mandatory part and an optional part. A reward function is associated with the execution of the optional part. In the first part of the talk, we discuss the solution to the optimal periodic RB scheduling problem which was open prior to our work. The RT-DVS problem is to minimize the energy consumption through the DVS, while still meeting all the deadlines.
