Description
Summary:碩士 === 國立臺灣大學 === 資訊工程學研究所 === 95 === This paper consider a scheduling problem for periodic jobs in a heterogeneous environment. There are m heterogeneous processors and n identical jobs. Jobs are available one at a time periodically. Each job is assigned to a processor. The goal is to minimizes the summation of completion time of all jobs. We propose a Minimum-Completion-First (MCF) for scheduling identical and periodic jobs to heterogeneous processors. We show that MCF is optimal under the restriction that the number of jobs is smaller than the amount of time unit for a fastest processor to process a job. We also conduct experiments to illustrate that MCF produces excellent schedules in general cases.
