| Outline of Final Research Achievements |
In this research, we newly proposed a macro-level approach to reduce the total energy consumption of a server to perform application processes. We newly discussed a migration approach where processes migrate to another server which is expected to consume smaller energy. Especially, processes migrate from a host server to a guest server by migrating virtual machines. By using virtual machines, processes on virtual machines can migrate without suspending the processes, i.e. live migration. As number of processes increases, virtual machines are newly created. A group of virtual machines migrate among servers. We also developed an eco simulator where the electric energy to be consumed by servers to perform application processes can be obtained. In the evaluation using the eco simulator, the total electric energy consumption [J] of servers and average execution time [sec] of processes can be reduced in the virtual machine algorithm proposed in this research compared with other algorithms.
