DATA DISTRIBUTION DEVICE FOR PARALLEL OPERATION PROCESSING SYSTEM, DATA DISTRIBUTION METHOD, AND DATA DISTRIBUTION PROGRAM

摘要

[Problem] To efficiently distribute data to individual computation nodes of a parallel operation processing system. [Solution] In the parallel operation processing system (1), a plurality of operation servers (101) perform parallel processing of data read from a storage device (106) via an I/O management server (102A) and an I/O server (102B), thereby performing high-speed operation processing. When the high-speed operation processing is performed, and a job is inputted from a user terminal (103), the I/O management server (102A) refers to a host definition information table (151), a rank disposition information table (152), an acceleration mechanism location information table (153), and an application properties information table (154) to determine on which operation server (101) each process of an executable program is executed, and whether each process uses a calculation acceleration mechanism (105). When it is determined that a process uses the operation acceleration mechanism (105), and is processed using the operation server (101) having the operation acceleration mechanism (105), I/O bandwidth is allocated to the process with priority.
