Abstract [en]
In this paper we present challenges that hinder the predictable integration and execution of real-time applications on multicore platforms. We investigate how shared resources, like CPU, memory-bus bandwidth, caches, and memory cause unpredictability and interference. We propose to adapt the traditional server-based scheduling approach on the multicore platforms with additional resource-reservations to control the shared access to such resources and present the multi-resource server as a solution such that the execution of real-time applications becomes predictable.
