Abstract

This paper presents the design of a multitasking executive for a course on computer operating systems. The system described here allows us to illustrate some fundamental concepts of multiprocessing and to experiment parallel programming.The system built is a preempt multitask one, which implements semaphore as a synchronisation tool of concurrent programs. A software layer called SESSION MANAGER is built above the basic kernel which is hence isolated from user's processes.The whole system is thus conceived to be written and tested by students during their courses on basic systems.
