摘要： A plurality of computers to execute jobs, a management computer to manage the execution of jobs and the disposition of data in the computers and a storage device storing data are interconnected via a network. The management program for the management computer divides the data into distributed data according to hint information and distributively disposes the distributed data and their replicas in memory storages allocated in memories of the computers. The computers execute the job using the distributed data allocated to their own memory. In the event of a fault in any of the computers, the management computer requests computers having the replicas of those distributed data disposed in the faulted computer to re-execute the job.

摘要： Provided is a computer system comprising a computer and a plurality of storage devices. The plurality of storage devices store divided data which is obtained by dividing data contained in a file which can be accesed by the computer. The computer holds configuration information of the processor included in the computer and configuration information of the file which is stored by dividing the file; divides an I/O request of the file into a plurality of I/O requests for the plurality of storage devices; determines whether a predetermined condition is satisfied or not; and assigns a plurality of I/O threads of a number determined based on a result of the determination to the divided plurality of I/O requests. The processor inputs/outputs the divided data of the file held in the plurality of storage devices by using the assigned the plurality of I/O threads.
