INQUIRY PARALLEL PROCESSING SYSTEM AND MACHINE-READABLE RECORDING MEDIUM WHERE PROGRAM IS RECORDED

摘要

PROBLEM TO BE SOLVED: To increase the total throughput of the inquiry parallel processing system by leveling the loads on respective computer nodes for partial inquiry processing when inquiries are processed in parallel on a cluster system composed of the computer nodes. SOLUTION: An inquiry analyzing means 11 analyzes a received inquiry to derive a processing procedure divided into partial inquiries. An inquiry integrating processing means 14 when distributing the partial inquiries to respective computer nodes 2-1 to 2-n determines the distribution number of partial inquiries to the respective computer nodes 2-1 to 2-n by using a distribution number determining means 13 so that the respective computer nodes are equal in the number of partial inquiries. The computer nodes at distribution destinations process the distributed partial inquiries and send the results back and an inquiry integrating process means 14 on a computer node at a distribution source derives the whole result while merging the returned results of the partial inquiries.
