Task Scheduling Observation and Stack Safety Analysis in Real Time Distributed Systems Using a Simulation Tool
Mikaël Briday, Jean-Luc Béchennec, Yvon Trinquet · 2006
This paper presents the ReTiS simulation tool and its use for real-time application analysis. Simulation concerns the operational architecture and takes into account the software (executable code of real-time tasks and real-time operating system) and the hardware (set of processors and networks). In this paper we show a mechanism that allows to detect task switch and to analyze task's stack (usage and corruption). This mechanism neither requires any application nor operating system code modification. We show its interest for the analysis of the temporal behavior of real-time applications in a distributed system
