Abstract:
Even though real-time systems have the stringent constraint of completing tasks before their deadlines, many existing real-time operating systems do not implement fault tolerance capabilities. In this paper we describe the development and implementation of a non-preemptive fault tolerant real-time policy for aperiodic dynamic tasks. We implemented non-preemptive fault-tolerant scheduling and recovery mechanism in the RT Mach operating system. The scheme is based on providing sufficient slack for each task to re-execute in case of transient and intermittent faults. In this implementation on RT Mach we created new kernel mechanisms and took advantage of some existing ones, with relatively few modifications.
