Enhancement of System Performance Using PeSche Scheduling Algorithm on Multiprocessors

Abstract

The scheduling techniques have been investigated by the job execution process in a system in order to maximize multiprocessor utilization. DPM (dynamic power management) and DVFS (dynamic voltage and frequency scaling) are two general strategies for lowering energy use. PeSche (performance enhanced scheduling) is a proposed scheduling algorithm that has been designed for an optimal solution. CodeBlocks were used to run the extensive simulations. In terms of computing performance (average waiting time and average turnaround time), the PeSche scheduling algorithm outperformed recently reported scheduling algorithms such as SJF, RR, FCFS, Priority, and SJF-LJF. PeSche scheduling algorithm gives better results by assigning the priority in terms of energy time ratio, programming running time, total energy and total time than existed algorithms. In comparison to minimum energy schedule (MES) and slack utilization for reduced energy (SURE), PeSche used less energy.
