Abstract

In the presence of caches, preemptive scheduling may incur a significant overhead referred to as cache-related preemption delay (CRPD). CRPD is caused by preempting tasks evicting cached memory blocks of preempted tasks, which have to be reloaded when the preempted tasks resume their execution.
In this paper we experimentally evaluate state-of-the-art techniques to account for the CRPD during timing analysis. We find that purely synthetically-generated task sets may yield misleading conclusions regarding the relative precision of different CRPD analysis techniques and the impact of CRPD on schedulability in general. Based on task characterizations obtained by static worst-case execution time (WCET) analysis, we shed new light on the state of the art.
