Abstract

This paper presents work in progress on an analysis method for message queues in a real-time multi-tasking system. This analysis will later be compared with simulation results, in which variations/distributions of execution times, task periods etc will be considered. The intention is to evaluate the level of pessimism in the analytical worst-case analysis, compared to the execution scenarios that actually occur in the real system. We will use these results as a basis for future work in the ARTES project RATAD, which aims at developing schedulability analysis with a wider applicability, by integrating reliability into real-time scheduling theory. What we want is a method for integrating reliability into classical real-time scheduling, so that we can guarantee, up to some level, that our system is working properly. This is to be compared with the classical 0/1 results of the schedulability theory.
