Abstract

Modern PCs are equipped with multi-many core capabilities which enhance their computational power and address important issues related to the efficiency of the scheduling processes of the modern operating system in such hybrid architectures. The aim of our work is to implement a simulation framework devoted to the study of the scheduling process in hybrid systems in order to improve the system performance. Through the simulator we are able to model events and to evaluate the scheduling policy for heterogeneous systems. We implemented as a use case a simple scheduling discipline, a non-prehemptive priority queue.
