This paper argues that OFFSCHED fits to the niche of Multiprocessors real time systems by partitioning a system to two; the operating system and OFFSCHED. OFFSHCED is a hybrid system. It is hybrid because it is both real time and still a regular Linux server. Real time is mainly achieved by the NMI characteristic and the CPU isolation. It is a hybrid system because OFFSCHED scheduler interacts with the operating system. -Mike.
