Many realtime systems rely on static scheduling algorithms. This includes cyclic scheduling, rate monotonic scheduling and fixed schedules created by offline scheduling techniques such as dynamic programming, heuristic search, and simulated annealing. However, for many realtime systems, static scheduling algorithms are quite restrictive and inflexible. For example, highly automated agile manufacturing, command, control and communications, and distributed realtime multimedia applications all operate over long lifetimes and in highly nondeterministic environments. Dynamic realtime scheduling algorithms are more appropriate for these systems and are used in such systems. Many of these algorithms are based on earliest deadline first (EDF) policies. There exists a wealth of literature on EDFbased scheduling with many extensions to deal with sophisticated issues such as precedence constraints, resource requirements, system overload, multiprocessors, and distributed systems. Deadline Scheduling for RealTime Systems: EDF and Related Algorithms aims at collecting a significant body of knowledge on EDF scheduling for realtime systems, but it does not try to be allinclusive (the literature is too extensive). The book primarily presents the algorithms and associated analysis, but guidelines, rules, and implementation considerations are also discussed, especially for the more complicated situations where mathematical analysis is difficult. In general, it is very difficult to codify and taxonomize scheduling knowledge because there are many performance metrics, task characteristics, and system configurations. Also, adding to the complexity is the fact that a variety of algorithms have been designed for different combinations of these considerations. In spite of the recent advances there are still gaps in the solution space and there is a need to integrate the available solutions. For example, a list of issues to consider includes: • preemptive versus nonpreemptive tasks, • uniprocessors versus multiprocessors, • using EDF at dispatch time versus EDFbased planning, • precedence constraints among tasks, • resource constraints, • periodic versus aperiodic versus sporadic tasks, • scheduling during overload, • fault tolerance requirements, and • providing guarantees and levels of guarantees (meeting quality of service requirements). Deadline Scheduling for RealTime Systems: EDF and Related Algorithms should be of interest to researchers, realtime system designers, and instructors and students, either as a focussed course on deadlinebased scheduling for realtime systems, or, more likely, as part of a more general course on realtime computing. The book serves as an invaluable reference in this fastmoving field.
