Computing system and control method

Abstract

A parallel or grid computing system that having a plurality of nodes and achieves job scheduling for the nodes with a view toward system efficiency optimization. The parallel or grid computing system has a plurality of nodes for transmitting and receiving data and a communication path for exchanging data among the nodes, which are either a transmitting node for transmitting data or a receiving node for processing a job dependent on transmitted data, and further has a time measuring means for measuring the time interval between the instant at which data is called for by a job and the instant at which the data is transmitted from a transmitting node to a receiving node, a time counting means for adding up the measured wait time data about each job, and a job scheduling means for determining the priority of jobs in accordance with the counted wait time and for scheduling jobs.
