【Abstract】 Scheduling policy is the key issue in job management system.Firstly,this paper introduces the architecture and work principle of OpenPBS,and presents the problem of the default FIFO in OpenPBS.Secondly,it designs and implements multiple-partition backfilling policy based on common scheduling policies and the main elements of scheduling decision.Finally,the results by simulation indicate that the proposed policy develops the performance of OpenPBS.更多还原
