Data distribution apparatus, data distribution method, and data distribution program for parallel computing processing system

Abstract

A problem is to distribute data efficiently to each computing node in a parallel computing processing system. A parallel computing processing apparatusaccomplishes high-speed computing processing by processing the data read out from a plurality of storage apparatusesvia an I/O management serverA and an I/O serverB in parallel by a plurality of computing servers. During the above, when a job is submitted from a user terminal, the I/O management serverA determines, with respect to a program to be executed, which of the computing serversexecutes each of the processes of the program and whether each of the processes uses a computing acceleration modulewith referring to a host definition information table, a rank arrangement information table, an acceleration module location information table, and an application characteristics information table. If the I/O management serverA determines that each of the processes uses the computing acceleration moduleand the process concerned is processed by the computing serverhaving the computing acceleration module, the I/O management serverA allots an I/O bandwidth for the process concerned preferentially.
