DISTRIBUTED PARALLEL DATA PROCESSOR AND RECORDING MEDIUM WITH DISTRIBUTED PARALLEL DATA PROCESSING PROGRAM, AND DISTRIBUTED PARALLEL DATA PROCESSING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a distributed parallel data processor for realizing high- processing performance, high reliability, and high extendibility by dividing large-scale data, and operating the distributed redundant storage of redundantly divided plural data, and to provide a device and method and system for improving throughput by operating load distribution for preventing the deterioration of the hit rate of cache, and to provide its recording medium. SOLUTION: At partial processing of each divided data, when a computer which makes hits of cache is present, partial processing is requested to the computer, and when any computer mis-hits the cache, the partial processing is requested to a computer whose load is minimum. Thus, it is possible to improve throughput by operating load distribution for preventing the deterioration of the hit rate of cache.
