Partial answers have been provided in the real-time literature to the question whether preemptive systems are better than non-preemptive systems. This question has been investigated by many authors according to several points of view and it still remains open. Compared to preemptive real-time scheduling, non-preemptive real-time scheduling and...

Non-preemptive real-time scheduling and the corresponding schedulability analyses have received considerable less attention in the research community, compared to preemptive real-time scheduling. However, non-preemptive scheduling is widely used in industry, especially in the case of hard real-time systems where missing deadlines leads to...

We consider the problem of fixed priority scheduling of non-preemptive strict periodic tasks in conjunction with sporadic preemptive tasks. There are few studies about the scheduling problem combining these two kinds of tasks. Moreover, only few results are available on scheduling non-preemptive strict periodic tasks since their performance...

We consider the problem of scheduling tasks with strict periods combined with sporadic tasks. Both types of task have fixed priorities and are preemptive. For a task with a strict period, %it is necessary to prove that for any job of the task, the difference between its starting time and its release time must be identical for every job. Tasks...
