摘要:
A real-time system includes a plurality of processors for executing jobs of a plurality of periodic tasks each having predetermined period, assigns each job in a period of each of the tasks to the processors, calculates distribution of execution times during which jobs assigned are executed on the processors, determines, based on the distribution, whether each of the jobs finishes by a deadline within the period, determines that scheduling is impossible, when one of the jobs is determined not to finish by the deadline, determines whether the distribution of the execution times of the jobs each determined to finish by the deadline converge, and determines that scheduling is possible, when the distribution converge.
