摘要

> Problem statement: This study proposed a TUF/UA real time scheduling algorithm known as Partition Preemptive Utility Accrual Scheduling (PUAS) also known as PPUAS algorithm. This algorithm addressed the overloaded problem that was identified in a uniprocessor scheduling environment and the necessity to design the scheduling algorithm in a multiprocessor environment. Approach: The PUAS algorithm was enhanced into the partitioned multiprocessor environment. The comparison of PUAS and PPUAS were made by using a discrete event simulation. Results: The proposed PUAS algorithm achieved a higher accrued utility for the entire load range as compared in the uniprocessor environment. Conclusion: Simulation results revealed that the proposed algorithms PPUAS are more efficient than the existing PUAS algorithm, producing a higher utility ratio and less abortion ratio making it suitable and efficient for real time application executed in multiprocessor environment.
