Data transfer control method of parallel distributed processing system, parallel distributed processing system, and recording medium

摘要

A parallel distributed processing system includes multiple parallel distributed processing execution servers which stores data blocks pre-divided in a storage device and executes tasks processing the data blocks in parallel, and a management computer controlling the multiple parallel distributed processing execution servers. The management computer collects resource use amounts of the multiple parallel distributed processing execution servers, acquires states of data blocks and tasks held by the multiple parallel distributed processing execution servers, selects a second parallel distributed processing execution server transferring a data block to the first parallel distributed processing execution server, based on processing progress situations of the data blocks held by the multiple parallel distributed processing execution servers and the resource use amounts of the multiple parallel distributed processing execution servers, and transmits a command to transfer the data block to the first parallel distributed processing execution server, to the selected second parallel distributed processing execution server.
