SCHEDULING PROGRAM FOR JOB EXECUTION, SCHEDULING METHOD FOR JOB EXECUTION, SCHEDULING APPARATUS FOR JOB EXECUTION

摘要

PROBLEM TO BE SOLVED: To level out the execution start of a normal job input to a queue in order of input to the queue as far as possible, in scheduling of a job for performing control to allow execution of a job of high priority before a normal job of non-high priority, regarding a distributed processing system provided with the queue to which the job is input for each of a plurality of information processing units.;SOLUTION: On the basis of a processing termination predicted time point for a job under execution in each of the information processing units and a processing execution predicted time point for a job of high priority input to each queue, a queue selection reference value is calculated for each queue. A shift processing object job is shifted to a queue having the smallest queue selection reference value, processing for calculating a new queue selection reference value in the queue on the basis of the processing execution predicted time point for a shift processing object job is selected and sequentially executed as the shift processing object job, in order of earlier input time for the queue regarding the normal jobs input in every queue.;COPYRIGHT: (C)2008,JPO&INPIT
