9781528217583: An Optimal Scheduling Algorithm With a Competitive Factor for Real-Time Systems

Synopsis

This book examines real-time systems. These are systems in which the correctness of a task depends on the completion time of that task. The author presents an algorithm he has designed to schedule tasks in such systems when there are more tasks than can be completed. The algorithm ensures that the system will obtain at least one quarter of the possible value that an ideal omniscient scheduling algorithm could obtain. The algorithm can be implemented using balanced search trees and runs at an amortized cost of O(log n) time per task, where n bounds the number of tasks in the system at any instant.
