Scheduling imprecise tasks in real-time distributed systems

The imprecise computation technique has been proposed as an approach to the construction of real time systems that are able to provide both guarantee and flexibility. The paper analyzes the utilization of imprecise computation in the scheduling of distributed real time applications. First we discuss the main problems associated with that goal, and we define a task model suitable for distributed environments. Then, the paper presents an approach to the scheduling of distributed imprecise tasks. Finally, we describe specific scheduling algorithms to be used within the proposed approach.
