Multiple sporadic servers as a mechanism for rescheduling aperiodic tasks are applicable to today's computer environments. A developed simulation tool enables evaluation of its performance for various task sets and server parameters. By increasing the number of servers, aperiodic task response time is reduced; system utilization and the number of reschedulings are increased whereas periodic task execution is disrupted insignificantly proper selection of server parameters improves task response time, and decreases the number of unnecessary reschedulings. Simulation results prove model correctness and simulation accuracy. The simulator is applicable to developing rescheduling algorithms and their implementation into real environments.
