Resource Management in Real-time Systems and Networks

Real-time computing and communication are enabling technologies for many current and future application areas. Many future real-time systems are expected to be highly dynamic. These systems operate for long periods in fault-prone non-deterministic environments under timing constraints. They need to be robust while delivering high real-time performance. Multiprocessor/Distributed systems are natural candidates for satisfying such requirements because of their potential for high performance and reliability. Such high-performance real-time systems demand efficient techniques for resource management [dynamic scheduling of real-time tasks (messages) onto processors (network) in the system]. In this talk, I first discuss two related issues in the area of resource management in multiprocessor/distributed real-time systems: (i) Dynamic task scheduling -- dynamic allocation of processors (including other resources) and time to real-time tasks, which have fault-tolerant requirements and/or resource constraints and/or precedence constraints among them, in such a way the timing constraints of these tasks are met. (ii) Resource reclaiming -- the problem of utilizing the resources left unused by a task when it executes less than its worst-case computation time or when a task is deleted from the current schedule. Resource reclaiming is used to adapt dynamically to these unpredictable situations to improve system performance. Then, I move onto the most important related issue of providing quality-of-service (QoS) guarantees on timeliness of message delivery and failure-recovery in real-time communication networks.
