Outline of Final Research Achievements |
Because the data management cluster often read data, we established a method to read the copy data which I held for high-reliability. We implemented prototype. We confirmed feasibility and evaluated performance and confirmed enough performance even if access concentrated on specific data. We established a method to place a virtual node by frequency of the data access. We compared it and evaluated it by a simulation experiment. We implemented the prototype of the platform which controlled a dispersed cluster and confirmed feasibility by operation check and a performance evaluation.
