Abstract
With the recent advent of multicore chips, real-time applications are now increasingly being deployed on multiprocessors.
The underlying real-time operating systems (RTOSs) must hence adapt to become "multicore-ready".
This poses a challenge: which scheduling and synchronization algorithms should be used to maximize RTOS flexibility and efficiency on multicore platforms?
This talk focusses on two relevant results. In the first part, I present an overhead-aware scheduler evaluation methodology and a case study, which highlights that the traditional choice of fixed-priority scheduling is indeed not the best choice for multicore systems. In the second part, I present the first provably optimal multiprocessor real-time locking protocol, which answers a long-open question pertaining to blocking optimality in multiprocessor real-time systems.
