This paper considers the problem of preemptive hard real-time scheduling of sporadic graph tasks on a uniprocessor with Earliest Deadline First (EDF). A sporadic graph task associated to an application is characterized by a set of subtasks under precedence constraints with deadline constraints. We study feasibility conditions based on the computation of the worst case response time of any subtask of a graph task. We investigate the late deadline constraint.
