JOB SCHEDULING METHOD BY IO CONFIGURATION

PROBLEM TO BE SOLVED: To provide a job scheduling being usable when having a large IO amount and especially, performing a large-scale file sharing in a field of processing large scale data at a high speed.SOLUTION: A computer system in which multiple nodes are connected by a network circuit, when scheduling a job to be executed in the computer system, by taking account of the IO configuration of the system, assigns a node being close in distance of IO route, to a disk device in which a data file for use in the job is stored, and secures the IO performance. When securing only a node being far in distance, the computer system copies the input file of the job in a disk device that is close to the secured node so as to secure the IO performance.
