Abstract
In this paper we study the performance of offline multiprocessor realtime schedules that
allows task migration compared to those that forbid migration. We consider an offline schedul
ing problem in which a given collection of tasks each with release time, computation time and
deadline are to be run on a multiprocessor system. A preemptive schedule allows the execu
tion of a task to be temporarily suspended and resumed at a later time. A migrative schedule
allows the task to resume on any processor whereas the nonmigrative schedule allows the task
